Description

物品管理システムおよび物品管理方法Article management system and article management method
　本発明は、例えば物流倉庫または物流センタにおける在庫の混載積付および格納指示等の物品管理に関する。 The present invention relates to article management such as stock loading and storage instruction in a distribution warehouse or distribution center, for example.
　倉庫において保管エリアの間口の利用効率を高めるために、物量の少ない在庫物品同士を組み合わせて１つのロケーションに混載格納する場合がある。また、保管エリアに格納された物量の少ない在庫物品同士を１ロケーションに集める（以降、棚寄せと称す）場合がある。 In order to increase the utilization efficiency of the frontage of the storage area in the warehouse, there are cases where stock items with a small quantity are combined and stored in one location. In addition, there are cases where inventory items with a small quantity stored in the storage area are collected in one location (hereinafter referred to as shelving).
　ここで、複数の在庫物品を組み合わせて棚寄せを行う技術として、特開２０１６―２２２４５５号公報（特許文献１）に記載の技術がある。 Here, there is a technique described in Japanese Patent Application Laid-Open No. 2016-222455 (Patent Document 1) as a technique for performing shelving by combining a plurality of inventory items.
　特許文献１には、「対象倉庫の荷役作業の決定において、対象倉庫内に現在保管中の製品の少なくとも保管位置を示す在庫情報と出荷条件を示す出荷製品情報とをもとに、現在保管中の製品を出荷条件の近い製品同士のグループに分け、対象倉庫の制約条件および在庫情報をもとに、グループ内の各製品を集めて配置するエリアをグループ毎に決定する。」と記載されている。 Patent Document 1 states that “in the determination of the cargo handling operation of the target warehouse, the product is currently stored based on the inventory information indicating at least the storage position of the product currently stored in the target warehouse and the shipped product information indicating the shipping conditions. Are divided into groups of products with similar shipping conditions, and based on the constraint conditions and inventory information of the target warehouse, the area in which the products in the group are collected and arranged is determined for each group. " Yes.
　特許文献１：特開２０１６－２２２４５５号公報 Patent Document 1: Japanese Patent Application Laid-Open No. 2016-222455
　倉庫の保管エリアでは、入荷した商品を保管エリアで保持し、配送・出荷先からのオーダに応じて出荷を行う。保管エリアへの格納作業では、一般的にはパレット（Ｐａｌｌｅｔ：以降、ＰＬと称す）に入荷検品後の商品を１ロケーション（以降、ロケと称す）に格納できる物量だけ積付けてから格納する。 In the storage area of the warehouse, the received products are held in the storage area and shipped according to orders from the delivery / shipping destination. In the storage operation in the storage area, in general, a product after arrival inspection is loaded onto a pallet (Pallet: hereinafter referred to as PL) after being loaded in an amount that can be stored in one location (hereinafter referred to as location).
　入荷商品によっては、入荷物量が１ＰＬに満たない場合、または、入荷物量が１ＰＬを超えるが、１ＰＬに満たない端数を含む場合がある。そのような場合には、複数の種類の商品を混載させて１ＰＬに積み付けてから保管エリアに格納する。これは、保管エリアの間口数に制限があることから、なるべく１ＰＬに積み付ける物量を増やして各間口の利用効率を高めることで、在庫のないロケーション（以降、空きロケと称す）を多く確保するためである。また、同様の目的で保管エリアに格納された物量の少ない在庫商品同士を１ロケーションに固める棚寄せが行われる場合がある。以降、複数種類の商品が混載されたＰＬを混載ＰＬと称す。 Depending on the products received, the amount of incoming goods may be less than 1PL, or the amount of incoming goods may exceed 1PL but may include fractions that are less than 1PL. In such a case, a plurality of types of commodities are mixedly loaded and stacked in 1PL and then stored in the storage area. This is because there is a limit on the number of storage areas, so as much as possible to increase the amount of goods to be loaded in 1PL and increase the usage efficiency of each frontage, thereby securing a large number of locations that are not in stock (hereinafter referred to as empty locations). Because. In addition, for the same purpose, there may be a case where shelves that stock items with a small quantity stored in the storage area are consolidated into one location. Hereinafter, a PL in which a plurality of types of products are mixedly mounted is referred to as a mixed PL.
　ここで、混載ＰＬでは、ＰＬ上の各商品の出荷傾向の違いから、各商品が消費（出荷）され尽くすまでの日数にばらつきが生じる。ここで、ある日（格納期間を計測した日）から商品の物量が消費され尽くすまでに掛かる日数を格納期間と称す。混載ＰＬにおいて、格納期間のばらつき（偏差）が大きい商品同士を混載させてしまうと、ＰＬ上の各商品の出荷が進むことで、ＰＬ上に格納期間の長い商品のみが残った状態となり、充填率(ロケに積付けた商品の容積/あるロケの容積)の低い状態となる。以降、このように混載ＰＬ上で１ＰＬに満たない物量の商品が残った状態のロケを歯欠け（低充填率）ロケと称す。なお、歯欠け（低充填率）ロケは単一商品が格納されたロケにおいても出荷が進めば発生するが、以降は混載ＰＬにおける積付商品の格納期間の違いから生じる歯欠け（低充填率）ロケを対象として扱う。 Here, in the mixed loading PL, the number of days until each product is consumed (shipped) varies due to the difference in the shipping tendency of each product on the PL. Here, the number of days taken from a certain day (the date when the storage period is measured) until the product quantity is consumed is referred to as a storage period. In mixed loading PL, if products with a large variation (deviation) in storage period are mixed and loaded, the shipment of each product on the PL advances, so that only the product with a long storage period remains on the PL. The rate (volume of goods loaded on location / volume of location) is low. Hereinafter, the location where the product with the quantity less than 1 PL remains on the mixed load PL is referred to as a tooth missing (low filling rate) location. In addition, tooth missing (low filling rate) location occurs even in locations where a single product is stored, but after that, tooth missing (low filling rate) caused by the difference in the storage period of the loaded product in the mixed loading PL ) Treat location as a target.
　歯欠け（低充填率）ロケは、同ロケ全ての商品が消費され尽くされないと別のＰＬを格納することができないため、これが多数発生すると間口の利用効率および回転率が低下してしまう。また、仮に歯欠け（低充填率）ロケの在庫を日々棚寄せすることができれば、間口の利用効率・回転率低下の問題は解決できるが、現実の物流倉庫では作業員の人数および作業時間帯が限られており、日々棚寄せを行うことは困難である。 Since the missing tooth (low filling rate) location cannot store another PL unless all the products in the location are consumed, the use efficiency and the rotation rate of the frontage are reduced when a large number of such locations occur. Also, if inventory of missing teeth (low filling rate) location can be stocked every day, the problem of frontage utilization efficiency and rotation rate decline can be solved, but in an actual distribution warehouse, the number of workers and work hours However, it is difficult to carry out shelving every day.
　特許文献１の技術は、倉庫に格納済の商品を棚寄せする場合の混載組合せの最適化に関するものである。同技術では、出荷製品情報を入力として、出荷時期および出荷先が近い在庫同士を１つまたは複数のロケに集めて配置するような混載指示を導出することで、保管エリアの空きロケの確保とその後の出荷作業効率の向上を図っている。しかし、前述の通り、棚寄せ作業を毎日のように行うことは困難であることから、入庫格納の段階でなるべく出荷時期が近い商品同士を混載させておくことが望まれる。 The technology of Patent Document 1 relates to optimization of a mixed combination when shelving items stored in a warehouse. With this technology, the shipment product information is input, and by deriving a mixed loading instruction that collects and arranges stocks close to the shipment date and destination in one or more locations, it is possible to secure empty locations in the storage area. The subsequent shipping work efficiency is improved. However, as described above, since it is difficult to carry out the shelving work every day, it is desirable to mix products that are as close as possible to shipment at the storage and storage stage.
　ここで、仮に特許文献１の技術を活用して入庫格納の段階で混載組合せを生成するためには、出荷製品情報が必要となる。ところが、特に、ＤＣ（Ｄｉｓｉｔｒｉｂｕｔｉｏｎ　Ｃｅｎｔｅｒ：保管型）の倉庫では、格納期間が長いもので数週間に及ぶため、入庫格納の段階で出荷製品情報が確定しており、かつ、それを入手可能であるとは限らない。出荷製品情報が入手不可能な状況では、特許文献１の技術を活用できない。 Here, in order to generate a mixed combination at the stage of storing goods using the technique of Patent Document 1, shipment product information is required. However, especially in DC (Distribution Center) warehouses, the storage period is long and it takes several weeks, so the shipping product information is finalized at the storage stage and can be obtained. Is not limited. In the situation where shipping product information is not available, the technique of Patent Document 1 cannot be utilized.
　以上によって、出荷製品情報が入手できない状況でも、入庫格納の段階で格納期間を予測して混載商品の組合せを最適化する混載積付・格納指示方式の立案が必要となる。 As described above, even when the shipment product information is not available, it is necessary to plan a mixed loading / storage instruction method that optimizes the combination of mixed products by predicting the storage period at the storage and storage stage.
　上記課題を解決するために、本発明の物品管理システムは、品目ごとに、他の品目の物品と混載して保管エリアに格納するか否かを決定する対象である混載候補の物品の数量、前記保管エリアに格納されている物品の数量、前記物品の前記保管エリアからの搬出順序、および、前記物品の前記保管エリアからの搬出実績を保持する記憶部と、前記記憶部に保持された情報に基づいて、品目ごとに、前記混載候補の物品の前記保管エリアからの搬出が終了する時期を予測する期間計算部と、前記予測された時期が互いに近い混載候補の物品の組合せを、前記保管エリアの同一の区画に格納される混載組合せとして決定する混載組合せ決定部と、前記決定した混載組合せを出力する出力部と、を有することを特徴とする。 In order to solve the above-mentioned problem, the article management system of the present invention provides, for each item, the quantity of articles that are candidates for mixed loading, which are targets for determining whether or not to be mixed with articles of other items and stored in a storage area. A storage unit that holds the quantity of articles stored in the storage area, the order of carrying out the articles from the storage area, and the results of carrying out the articles from the storage area, and information held in the storage unit Based on the above, for each item, a period calculation unit that predicts when the carrying out of the mixed loading candidate article from the storage area is completed, and a combination of the mixed loading candidate article whose predicted time is close to each other It has a mixed combination determination part determined as a mixed combination stored in the same section of the area, and an output part that outputs the determined mixed combination.
　出荷製品情報のない場合でも、格納期間が似通った商品同士で混載組合せを導出することができ、混載する商品の格納期間の違いから生じる歯欠け（低充填率）ロケの発生を抑止して保管エリアの間口の利用効率・回転率を高めることができる。 Even when there is no shipment product information, it is possible to derive a mixed loading combination between products with similar storage periods, and suppress the occurrence of missing teeth (low filling rate) location caused by the difference in the storage period of mixed products. Use efficiency and turnover at the frontage of the area can be increased.

　以下、本発明の実施形態の詳細を説明する。 Hereinafter, details of the embodiment of the present invention will be described.
　図１は、本発明の実施例１の混載積付・格納指示装置が使用される倉庫のレイアウトの説明図である。 FIG. 1 is an explanatory diagram of a layout of a warehouse in which the mixed loading / storage instruction apparatus according to the first embodiment of the present invention is used.
　図１に例示する倉庫１００は、保管エリア１０１及びアクティブエリア１０２を含む。保管エリア１０１は、複数のロケ１０３を含み、入荷バース１０４に到着した商品は、ＰＬに積付けられた後にいずれか１つのロケ１０３に保管される。すなわち、各ロケは、保管エリア１０１内の区画であり、商品の格納位置である。 The warehouse 100 illustrated in FIG. 1 includes a storage area 101 and an active area 102. The storage area 101 includes a plurality of locations 103, and the products that arrive at the arrival berth 104 are stored in any one location 103 after being loaded on the PL. In other words, each location is a section in the storage area 101 and is a storage position of a product.
　出荷される商品の最小単位はピース（Ｐｃｓ）であるが、保管エリア１０１では、通常、所定の数のＰｃｓがケース（ＣＳ）にまとめられており、ＣＳごとに出荷される場合もある。商品がＣＳごとに出荷される場合（これをＣＳ出荷と称す）、ロケ１０３から取り出されたＣＳが出荷バース１０５に運ばれ出荷される。商品がＰｃｓごとに出荷される場合、必要に応じて商品がアクティブエリア１０２に補充され、そこから必要なＰｃｓ数の商品が出荷バース１０５に運ばれ、出荷される。すなわち、アクティブエリア１０２は、Ｐｃｓ（単品）の商品を保管するエリアである。 The minimum unit of goods to be shipped is a piece (Pcs), but in the storage area 101, a predetermined number of Pcs are usually collected in a case (CS) and may be shipped for each CS. When the product is shipped for each CS (this is referred to as CS shipping), the CS taken out from the location 103 is transported to the shipping berth 105 and shipped. When a product is shipped for each Pcs, the product is replenished to the active area 102 as necessary, and a necessary number of Pcs products are transported to the shipping berth 105 and shipped. In other words, the active area 102 is an area for storing Pcs (single item) products.
　なお、図１に示すレイアウトは一例であり、本発明は任意のレイアウトの倉庫に適用することができる。例えば、保管エリア、アクティブエリア、入荷バース及び出荷バースの位置関係は任意であり、保管エリアに含まれるロケ数も任意である。 The layout shown in FIG. 1 is an example, and the present invention can be applied to a warehouse having an arbitrary layout. For example, the positional relationship between the storage area, the active area, the incoming berth and the shipping berth is arbitrary, and the number of locations included in the storage area is also arbitrary.
　実施例１では、保管エリア１０１内の１つのロケ１０３に対して、１ＰＬずつ格納されるものとして説明する。また、１ＰＬには１つまたは複数のＳＫＵ（Ｓｔｏｃｋ　Ｋｅｅｐｉｎｇ　ｕｎｉｔ）の商品が載っているものとし、１ＳＫＵは１商品の１ロット名に相当するものとする。また、実施例１で想定する倉庫１００では、同一商品に対してロット名の５０音順（降順）でＣＳ出荷および補充の引当が掛かる（すなわちその順で出荷および補充が行われる）ものとする。 In the first embodiment, it is assumed that 1 PL is stored for each location 103 in the storage area 101. In addition, it is assumed that one PL or a plurality of SKU (Stock Keeping Unit) products are included in 1PL, and one SKU corresponds to one lot name of one product. Further, in the warehouse 100 assumed in the first embodiment, it is assumed that CS shipment and replenishment are allocated to the same product in the order of the alphabetical order of the lot name (descending order) (that is, shipping and replenishment are performed in that order). .
　但し、本発明の装置の適用範囲はロット管理がされている商品に限定されるものではない。同一の商品が複数のロケに格納されている場合に、その商品の引当順序が倉庫の運用上決まっているならば、本発明の装置は適用可能である。 However, the scope of application of the apparatus of the present invention is not limited to products for which lot management is performed. In the case where the same product is stored in a plurality of locations, the apparatus of the present invention is applicable if the order of allocation of the product is determined by the operation of the warehouse.
　ここで、引当順序とは、保管エリアに格納されている商品が出荷および補充の少なくともいずれかのために保管エリアから搬出される順序であり、本実施例では上記のとおりロット名の順に商品が搬出される。しかし、ロット名は引当順序を決定する情報の一例であり、実際には種々の情報に基づいて引当順序を決定することができる。例えば、記憶部１１に商品が入荷した順序を示す情報が保持され、その順序がそのまま引当順序として使用されてもよい。あるいは、例えば商品が食品である場合などのように、商品の消費期限が定められている場合は、記憶部１１に商品の消費期限を示す情報が保持され、消費期限が早く到来する順に商品が搬出されてもよい。 Here, the allocation order is the order in which the products stored in the storage area are carried out of the storage area for at least one of shipment and replenishment. In this embodiment, the products are arranged in the order of the lot names as described above. It is carried out. However, the lot name is an example of information for determining the allocation order. In practice, the allocation order can be determined based on various information. For example, information indicating the order in which products are received may be stored in the storage unit 11, and the order may be used as it is as an allocation order. Or when the expiration date of goods is defined, for example, when the goods are food, for example, the information indicating the expiration date of the goods is stored in the storage unit 11, and the products are listed in the order in which the expiration dates come earlier. It may be carried out.
　以降の説明では、入荷バースに到着後の商品を積み付けて、これから格納を行うＰＬを「格納ＰＬ」、保管エリアに保管済の在庫商品が積み付けられたＰＬを「在庫ＰＬ」と呼ぶ。 In the following description, the product that arrives at the arrival berth is loaded and the PL to be stored is called “stored PL”, and the PL that is stocked in the storage area is called “stock PL”.
　図２は、本発明の実施例１の混載積付・格納指示装置１０のハードウェア構成を示すブロック図である。 FIG. 2 is a block diagram showing a hardware configuration of the mixed loading / storage instruction apparatus 10 according to the first embodiment of the present invention.
　図２に示す混載積付・格納指示装置１０は、例えば倉庫等における物品の混載積付・格納指示といった物品管理のための処理を行うシステムの一例であり、相互に接続された記憶部１１及び演算部１２を有する計算機である。記憶部１１は、例えば半導体記憶装置、磁気ディスク装置、又はそれらの組合せ等であり、演算部によって実行されるプログラム及び演算部の処理の際に参照されるデータ等を格納する。演算部１２は、記憶部１１に格納されたプログラムに記述された命令に従って、後述する種々の処理を実行するプロセッサである。 A mixed loading / storage instruction device 10 shown in FIG. 2 is an example of a system that performs processing for article management, such as an instruction for mixed loading / storage of articles in a warehouse or the like. This is a computer having a calculation unit 12. The storage unit 11 is, for example, a semiconductor storage device, a magnetic disk device, or a combination thereof, and stores a program executed by the calculation unit, data that is referred to in the processing of the calculation unit, and the like. The arithmetic unit 12 is a processor that executes various processes described later in accordance with instructions described in a program stored in the storage unit 11.
　混載積付・格納指示装置１０には、入力部１３及び出力部１４が接続される。入力部１３は、例えばキーボード、マウスおよびハンディターミナルのような、情報の入力を受け付けるデバイスであり、出力部１４は、例えば画像表示装置、プリンタおよびハンディターミナルのような、情報を出力するデバイスである。 An input unit 13 and an output unit 14 are connected to the mixed loading / storage instruction device 10. The input unit 13 is a device that receives information input, such as a keyboard, a mouse, and a handy terminal. The output unit 14 is a device that outputs information, such as an image display device, a printer, and a handy terminal. .
　ここで、近年の倉庫業務では機械化が進んでおり、ＰＬへの商品の積付作業や格納作業を自動積付ロボットまたは自動搬送ロボットなどの機械が執り行う形態が見られている。そのような場合に備え、出力部１４は、倉庫業務を行う機械が読み込めるような形で推奨混載組合せリスト１９を出力できる機能を備えていることが望ましい。これによって、機械によって混載積付作業および格納作業を行う場合にも、保管エリアの間口の利用効率・回転率の高い混載積付の組合せを実現することが可能となる。 Here, mechanization is progressing in recent warehouse operations, and there is a form in which a machine such as an automatic loading robot or an automatic transfer robot performs a loading operation and a storing operation of goods on a PL. In preparation for such a case, it is desirable that the output unit 14 has a function of outputting the recommended mixed combination list 19 in a form that can be read by a machine that performs warehouse operations. This makes it possible to realize a combination of mixed loading with high utilization efficiency and high rotation rate of the frontage of the storage area even when performing the mixed loading operation and the storage operation by the machine.
　混載積付・格納指示装置１０は、さらに、演算部１２に接続されたネットワークインターフェースを介して倉庫内ネットワークに接続される。図２は、本発明の実施例１の混載積付・格納指示装置１０を倉庫内ネットワークに接続した場合のネットワーク構成を示している。一般的に倉庫内ネットワークには、ＷＭＳ（Ｗａｒｅｈｏｕｓｅ　Ｍａｎａｇｅｍｅｎｔ　Ｓｙｓｔｅｍ）と呼ばれる、商品の在庫管理などを行う倉庫管理システムのデータベース１５及びアプリサーバ１６が接続されている。ネットワークの形態は有線又は無線のいずれであってもよい。また、実施例１の混載積付・格納指示装置１０は、倉庫管理システムデータベース１５内のなるべく最新のデータを読み込むことが可能であれば、必ずしも倉庫内ネットワークに接続されていなくとも、利用可能である。 The mixed loading / storage instruction device 10 is further connected to a network in the warehouse via a network interface connected to the calculation unit 12. FIG. 2 shows a network configuration when the mixed loading / storage instruction apparatus 10 according to the first embodiment of the present invention is connected to a warehouse network. In general, the warehouse network is connected with a database 15 and an application server 16 of a warehouse management system called WMS (Warehouse Management System) for managing inventory of goods. The form of the network may be either wired or wireless. Further, the mixed loading / storage instruction device 10 of the first embodiment can be used even if it is not necessarily connected to the warehouse network, as long as the latest data in the warehouse management system database 15 can be read. is there.
　図３は、本発明の実施例１の混載積付・格納指示装置１０の構成を示す機能ブロック図である。 FIG. 3 is a functional block diagram showing the configuration of the mixed loading / storage instruction apparatus 10 according to the first embodiment of the present invention.
　図３では、混載積付・格納指示装置１０が倉庫管理システムデータベース１５および倉庫管理システムアプリサーバ１６とは独立した計算機上に実装されて動作することを想定して説明する。但し、本発明の実施形態はこの形態に限る必要は無い。例えば、後述する混載積付・格納指示装置１０の機能が、倉庫管理システムアプリサーバ１６上で動作する１つのアプリケーションという形で実現されても良い。 In FIG. 3, the explanation will be made on the assumption that the mixed loading / storage instruction apparatus 10 is mounted on a computer independent of the warehouse management system database 15 and the warehouse management system application server 16 and operates. However, the embodiment of the present invention need not be limited to this form. For example, the function of the mixed loading / storage instruction device 10 to be described later may be realized in the form of one application that operates on the warehouse management system application server 16.
　図３の記憶部１１は、図２の倉庫管理システムデータベース１５から、倉庫の在庫データ１１１および過去の在庫消費実績１１２を読み込んで保持している。また、記憶部１１は、商品マスタ１１０、区分けルール１１３、制約条件１１４およびロケマスタ１１５を合わせて保持している。 3 reads and holds warehouse inventory data 111 and past inventory consumption results 112 from the warehouse management system database 15 of FIG. In addition, the storage unit 11 holds a product master 110, a classification rule 113, a constraint condition 114, and a location master 115.
　なお、上記の在庫消費実績１１２および後述する在庫消費ＣＳ数１１２ｃ（図１２参照）等における「消費」とは、商品が出荷または補充等のために保管エリア１０１から搬出され、その結果、保管エリア１０１内に存在しなくなることを意味する。 Note that “consumption” in the above-mentioned inventory consumption record 112 and the inventory consumption CS number 112c (see FIG. 12) described later, etc. means that the product is unloaded from the storage area 101 for shipment or replenishment. This means that it no longer exists in 101.
　図３の演算部１２は、入力部１３が読み込んだ入荷予定リスト１７と、記憶部１１から読み込んだ上記の各種データ１１０～１１５とを用いて、推奨混載組合せリスト１９を導出する。図３の演算部１２は、混載候補抽出部１２０、総在庫数計算部１２１、平均在庫消費数計算部１２２、格納期間算出部１２３、格納期間比較部１２４、及び混載組合せ決定部１２５というプログラムモジュールを保持している。後述するように、混載候補抽出部１２０は、混載候補商品（商品名）１８１を含む混載候補商品リスト１８を生成する。総在庫数計算部１２１は、混載候補商品までの総在庫数２０を計算する。平均在庫消費数計算部１２２は、混載候補商品の平均在庫消費数２１を計算する。格納期間算出部１２３は、格納期間２２を算出する。格納期間比較部１２４は、混載候補商品区分けリスト２３を生成する。 3 uses the arrival schedule list 17 read by the input unit 13 and the various data 110 to 115 read from the storage unit 11 to derive the recommended mixed combination list 19. 3 includes a mixed loading candidate extraction unit 120, a total inventory number calculation unit 121, an average inventory consumption number calculation unit 122, a storage period calculation unit 123, a storage period comparison unit 124, and a mixed loading combination determination unit 125. Holding. As will be described later, the mixed loading candidate extraction unit 120 generates a mixed loading candidate product list 18 including a mixed loading candidate product (product name) 181. The total inventory quantity calculation unit 121 calculates the total inventory quantity 20 up to the mixed candidate product. The average inventory consumption number calculation unit 122 calculates the average inventory consumption number 21 of the mixed candidate product. The storage period calculation unit 123 calculates the storage period 22. The storage period comparison unit 124 generates a mixed candidate product classification list 23.
　ここで、プログラムモジュール１２０から１２５は実際には記憶部１１の中にプログラムとして書き込まれているものである。よって、演算部１２がそれらのプログラムを読み込んで図５にて説明するステップＳ１～Ｓ１０の処理を実行するが、本明細書では便宜的に各ステップの処理の主体は前記１２０～１２５のいずれかのプログラムモジュールであるものとして説明する。 Here, the program modules 120 to 125 are actually written as programs in the storage unit 11. Therefore, the calculation unit 12 reads those programs and executes the processing of steps S1 to S10 described in FIG. 5. In this specification, for the sake of convenience, the main body of the processing of each step is any one of the above 120 to 125. It is assumed that the program module is
　図４は、本発明の実施例１における入力部１３の一形態を示す説明図である。 FIG. 4 is an explanatory diagram showing one form of the input unit 13 according to the first embodiment of the present invention.
　ここでは、計算機の表示部に表示されるＧＵＩ（Ｇｒａｐｈｉｃａｌ　Ｕｓｅｒ　Ｉｎｔｅｒｆａｃｅ）として入力部１３を説明する。 Here, the input unit 13 will be described as a GUI (Graphical User Interface) displayed on the display unit of the computer.
[規則91に基づく訂正 04.08.2017]　
　混載積付・格納指示装置１０の利用者は、入力部１３のモード選択欄５０１の中からいずれかひとつの機能を選択する。図４の例では、モード選択欄５０１において、混載積付指示５０１ａ、詰込み格納指示５０１ｂおよび棚寄せ指示５０１ｃのいずれかが選択可能である。[Correction 04.08.2017 based on Rule 91]
The user of the mixed loading / storage instruction device 10 selects any one function from the mode selection field 501 of the input unit 13. In the example of FIG. 4, in the mode selection column 501, any of the mixed loading instruction 501a, the stuffing / storage instruction 501b, and the shelving instruction 501c can be selected.
　ここで、モード選択欄５０１における混載積付指示５０１ａは、入荷格納の段階で入荷商品１７１同士の混載組合せを導出する機能を動作させる指示であり、この機能については実施例１にて説明する。詰込み格納指示５０１ｂは、１ＰＬ分の物量に満たない入荷商品１７１を、保管エリアの在庫の存在するロケに詰込み格納指示を出す機能を動作させる指示である。この機能の詳細は実施例２にて説明する。最後に棚寄せ指示５０１ｃは、保管エリアの在庫同士を組合せて混載組合せの生成を行う機能を動作させる指示のことである。この機能の詳細は実施例３にて説明する。 Here, the mixed loading instruction 501a in the mode selection column 501 is an instruction to operate a function for deriving a mixed loading combination of the incoming goods 171 at the stage of receiving and storing, and this function will be described in the first embodiment. The stuffing storage instruction 501b is an instruction to operate the function of issuing a stuffing storage instruction to the location where the stock in the storage area is in stock for the goods 171 that are less than the quantity for 1PL. Details of this function will be described in the second embodiment. Finally, the shelf gathering instruction 501c is an instruction to operate a function for generating a mixed combination by combining stocks in the storage area. Details of this function will be described in a third embodiment.
　入力部１３は、さらに、入荷予定リスト名入力欄５０２および実行ボタン５０３を含む。利用者が入荷予定リスト名入力欄５０２に入荷予定リストを識別する情報を入力し、モード選択欄５０１においていずれかの機能を指示して、実行ボタン５０３を操作すると、混載積付・格納指示装置１０は、入荷予定リスト名入力欄５０２に入力された情報によって識別される入荷予定リストを対象として、モード選択欄５０１において指示された機能が実行される。 The input unit 13 further includes a scheduled arrival list name input field 502 and an execution button 503. When the user inputs information for identifying the arrival schedule list in the arrival schedule list name input field 502, designates any function in the mode selection field 501, and operates the execution button 503, the mixed loading / storage instruction device 10, the function instructed in the mode selection column 501 is executed for the arrival schedule list identified by the information input in the arrival schedule list name input field 502.

　以降、図５を用いて本発明の実施形態について詳細を説明する。 Hereinafter, the embodiment of the present invention will be described in detail with reference to FIG.
[規則91に基づく訂正 04.08.2017]　
　ステップＳ１（図５）：演算部１２は、記憶部１１から各種データ１１０～１１５を取得する。[Correction 04.08.2017 based on Rule 91]
Step S1 (FIG. 5): The calculation unit 12 acquires various data 110 to 115 from the storage unit 11.
[規則91に基づく訂正 04.08.2017]　
　ステップＳ２（図５）：混載候補抽出部１２０は、入力部１３から終了の入力があれば、装置全体の動作を終了させる。何も入力がない場合は、入力待ちを継続する。ただし、入荷予定リストおよびモードの指定を含む実行指示が入力された場合は、後述するＳ３が実行される。[Correction 04.08.2017 based on Rule 91]
Step S2 (FIG. 5): If there is an end input from the input unit 13, the mixed candidate extraction unit 120 ends the operation of the entire apparatus. If there is no input, the input wait is continued. However, when an execution instruction including the arrival schedule list and mode designation is input, S3 described later is executed.
[規則91に基づく訂正 04.08.2017]　
　ステップＳ３（図５）：混載候補抽出部１２０は、入力部１３のモード選択欄５０１において混載積付指示５０１ａが指定され、入荷予定リスト名入力欄５０２において入荷予定リスト１７（入荷商品名１７１、ロット名１７２、入荷予定日時１７３、入荷ＣＳ数１７４、カテゴリ１７５）が入力され、かつ実行ボタン５０３を介して実行指示が入力された場合、ステップＳ４に進む。何も入力がない場合は、入力待ちを継続する。[Correction 04.08.2017 based on Rule 91]
Step S3 (FIG. 5): The mixed loading candidate extraction unit 120 designates the mixed loading instruction 501a in the mode selection column 501 of the input unit 13, and the scheduled loading list 17 (arrived shipping product name 171; If a lot name 172, scheduled arrival date and time 173, received CS number 174, category 175) are input and an execution instruction is input via the execution button 503, the process proceeds to step S4. If there is no input, the input wait is continued.
　入荷予定リスト１７は、入荷商品名１７１、ロット名１７２、入荷予定日時１７３、入荷ＣＳ数１７４およびカテゴリ１７５を含む。ここでカテゴリ１７５とは、入荷予定リスト１７の中のどの商品同士を混載させるかをユーザが指定するためのものである。本実施例では、カテゴリ１７５の列に同一の文言（すなわち同一の値）があるもの同士で混載組み合わせが導出される。例えば、ユーザは入荷予定日時１７３が近い（例えば入荷予定日時１７３の差が所定の値より小さい）商品同士、および、同一の入荷トラックの便で入荷される商品同士を同一カテゴリに指定することが想定される。入荷する時期が異なる商品を混載しようとすると、先に入荷する商品が入荷してから後に入荷する商品が入荷するまで当該商品を保管エリア１０１に格納できないが、上記のように、近い時期に入荷する商品の範囲内で混載組合せを導出することによって、効率的に入荷の格納を行うことができる。 The arrival schedule list 17 includes an arrival product name 171, a lot name 172, an expected arrival date and time 173, an arrival CS number 174, and a category 175. Here, the category 175 is for the user to specify which products in the arrival schedule list 17 are mixed. In the present embodiment, the mixed combination is derived from those having the same wording (that is, the same value) in the column of the category 175. For example, the user may designate the products that are close to the scheduled arrival date and time 173 (for example, the difference between the scheduled arrival dates and times 173 is smaller than a predetermined value) and the products that are received on the same arrival truck as the same category. is assumed. If you try to load products that arrive at different times, you cannot store the products in the storage area 101 until the products that arrive later arrive after the products that arrive first. By deriving the mixed combination within the range of the product to be received, the arrival can be efficiently stored.
　なお、もし入荷トラック便名または入荷予定日時が同一の入荷商品を同一カテゴリとするのであれば、カテゴリ１７５の列に入荷トラック便名または入荷予定日時１７３の列と同じ値を入力すれば良い。入荷予定リスト１７の詳細は、図６を参照して後述する。 It should be noted that if a received product having the same arrival truck flight name or scheduled arrival date / time is set to the same category, the same value as that of the incoming truck flight name or scheduled arrival date / time 173 may be entered in the column of category 175. Details of the arrival schedule list 17 will be described later with reference to FIG.
　ここで、入力部１３は、例えば、ハンディターミナルの画面によって実現されても良い。この場合、例えば入荷予定リスト１７の各行に１つずつバーコードが印字された列を追加しておき、利用者がハンディターミナルなどで各行のバーコードを読み取ることによって入荷予定リスト１７を入力しても良い。このような形態の場合、倉庫の入荷バース１０４の作業員が本装置１０を使う場合に、実物に表示された入荷商品名と入荷予定リスト１７の入荷商品名１７１とを照合しながら推奨混載組合せリスト１９を出力することができ、入荷検品作業およびＰＬへの積付作業の効率化が図れる。 Here, the input unit 13 may be realized, for example, by a handy terminal screen. In this case, for example, a column in which a barcode is printed is added to each line of the arrival schedule list 17, and the user inputs the arrival schedule list 17 by reading the barcode of each line with a handy terminal or the like. Also good. In the case of such a form, when the worker of the arrival berth 104 in the warehouse uses the apparatus 10, the recommended mixed loading combination is performed while comparing the arrival product name displayed in the actual product with the arrival product name 171 in the arrival schedule list 17. The list 19 can be output, and the efficiency of the incoming inspection work and the loading work to the PL can be improved.

　ステップＳ４（図５）：混載候補抽出部１２０は、入荷予定リスト１７および商品マスタ１１０を参照して、混載候補商品を抽出し、混載候補商品リスト１８を生成する。混載候補商品リスト１８の詳細は、図７を参照して後述する。[Correction 04.08.2017 based on Rule 91]
Step S4 (FIG. 5): The mixed loading candidate extraction unit 120 refers to the arrival schedule list 17 and the product master 110, extracts mixed loading candidate products, and generates a mixed loading candidate product list 18. Details of the mixed candidate product list 18 will be described later with reference to FIG.
　ここで、混載候補商品リスト１８に含まれるＰＬ換算入荷物量１８２は、それぞれの商品の入荷量（例えば入荷ＣＳ数）を、ＰＬ数に換算した値（言い換えると、入荷した商品を積み付けるために必要なＰＬの数）であり、商品マスタ１１０に定義された１ＰＬあたりの積付可能ＣＳ数１１０ｂを用いて式（１）によって算出される。 Here, the PL converted arrival amount 182 included in the mixed candidate product list 18 is a value obtained by converting the arrival amount (for example, the number of received CSs) of each item into the number of PLs (in other words, for loading the received items). The number of necessary PLs), and is calculated by the equation (1) using the CS number 110b that can be loaded per 1PL defined in the product master 110.
ＰＬ換算入荷物量１８２
＝入荷ＣＳ数１７４／１ＰＬあたり積付可能ＣＳ数１１０ｂ　式（１） PL conversion amount 182
= Number of CSs that can be loaded per received 174 / 1PL 110b Formula (1)
　また、混載候補商品リスト１８に含まれる混載対象物量１８３は、入荷ＣＳ数１７４を１ＰＬあたり積付可能なＣＳ数１１０ｂで割った余り（すなわち、式（１）の計算結果の小数点以下の部分）が該当する。また、混載対象物量１８３が生じる入荷商品が混載候補商品１８１にあたる。本実施例では、上記のようにして計算された混載対象物量１８３が示す数量の混載候補商品１８１が、他の品目の商品と混載して保管エリア１０１に格納するか否かを決定する対象となる。 Further, the mixed load target amount 183 included in the mixed load candidate product list 18 is the remainder obtained by dividing the received CS number 174 by the CS number 110b that can be loaded per 1PL (that is, the portion after the decimal point of the calculation result of Expression (1)). Is applicable. In addition, a received product in which the mixed load amount 183 is generated corresponds to the mixed load candidate product 181. In the present embodiment, an object for determining whether or not the mixed loading candidate product 181 of the quantity indicated by the mixed loading target amount 183 calculated as described above is to be mixed with other items and stored in the storage area 101. Become.
[規則91に基づく訂正 04.08.2017]　
　ステップＳ５（図５）：総在庫数計算部１２１は、混載候補商品リスト１８および在庫データ１１１から、混載候補商品名１８１と同一名の商品で、かつ、ロット名１１１ｃを参照して、ロット名ごとの（すなわち引当順序ごとの）商品の在庫数に基づいて引当順序が早い同一商品の在庫ＣＳ数１１１ｄを取得して、混載候補商品までの総在庫数２０を算出する。混載候補商品までの総在庫数２０は、混載候補商品よりも引当順序の早い全ての同一商品の在庫ＣＳ数の総和に、混載候補商品のＣＳ数を加算した数として算出される。言い換えると、混載候補商品までの総在庫数２０は、混載候補商品名１８１と同一名の（すなわち同一品目の）商品を、引当順序に従って保管エリア１０１から搬出していった場合に、混載候補商品の搬出が終了するまでに搬出される当該品目の商品の数に相当する。これを計算することによって、混載候補商品の搬出が終了する時期を精度よく予測することができる。[Correction 04.08.2017 based on Rule 91]
Step S5 (FIG. 5): The total stock quantity calculation unit 121 refers to the lot name 111c from the mixed candidate product list 18 and the inventory data 111 with the same name as the mixed candidate product name 181 and the lot name 111c. The inventory CS number 111d of the same product with the early allocation order is acquired based on the inventory number of each product (that is, for each allocation order), and the total inventory number 20 up to the mixed candidate product is calculated. The total inventory number 20 up to the mixed candidate product is calculated as the sum of the CS numbers of the mixed candidate product added to the sum of the inventory CS numbers of all the same products that are allocated earlier than the mixed candidate product. In other words, the total inventory number 20 up to the mixed loading candidate product is the mixed loading candidate product when a product having the same name as the mixed loading candidate product name 181 (that is, the same item) is carried out from the storage area 101 according to the allocation order. This corresponds to the number of commodities of the item to be unloaded before the end of unloading. By calculating this, it is possible to accurately predict when the mixed candidate product has been taken out.
[規則91に基づく訂正 04.08.2017]　
　ステップＳ６（図５）：平均在庫消費数計算部１２２は、混載候補商品名１８１および在庫消費実績１１２から、混載候補商品の平均在庫消費数２１を算出する。ここで在庫消費とは、ＣＳ出荷またはアクティブエリア１０２への補充などのために保管エリア１０１から各商品が消費されていくこと（すなわち各商品が保管エリア１０１から搬出された結果、保管エリア１０１内には存在しなくなること）の総称である。例えば在庫消費実績はＣＳ出荷実績および補充実績が含まれる。平均在庫消費数２１は、単位時間（例えば１日）当たりの在庫消費の平均であり、式（２）によって算出される。[Correction 04.08.2017 based on Rule 91]
Step S <b> 6 (FIG. 5): The average inventory consumption number calculation unit 122 calculates the average inventory consumption number 21 of the mixed candidate product from the mixed candidate product name 181 and the inventory consumption result 112. Here, the inventory consumption means that each product is consumed from the storage area 101 for CS shipment or replenishment to the active area 102 (that is, as a result of each product being carried out from the storage area 101, Is a general term for the fact that it no longer exists. For example, the inventory consumption record includes a CS shipment record and a replenishment record. The average inventory consumption number 21 is an average of inventory consumption per unit time (for example, one day), and is calculated by Expression (2).
平均在庫消費数２１
＝Σ在庫消費パタンごとの一定期間の在庫消費数の総和／一定期間の日数　式（２） Average inventory consumption 21
= Sum of inventory consumption for a certain period for each Σ inventory consumption pattern / number of days for a certain period (2)
[規則91に基づく訂正 04.08.2017]　
　ステップＳ７（図５）：格納期間算出部１２３は、各混載候補商品１８１の格納期間２２を、混載候補商品までの総在庫数２０および平均在庫消費数２１から、式（３）によって算出する。[Correction 04.08.2017 based on Rule 91]
Step S <b> 7 (FIG. 5): The storage period calculation unit 123 calculates the storage period 22 of each consolidated candidate product 181 from the total inventory number 20 and the average inventory consumption number 21 up to the consolidated candidate product by Equation (3).
格納期間２２
＝混載候補商品までの総在庫数２０／平均在庫消費数２１　式（３） Storage period 22
= Total inventory number of up to 20 candidate products / average inventory consumption number 21 formula (3)
　格納期間２２は、混載候補商品１８１が保管エリア１０１から全て搬出されるまでの期間の長さである。このような格納期間２２の評価を行うことで、混載候補商品１８１が引当順序に則ってこれまでの実績と同じ速さで消費されると仮定した場合に、保管エリア１０１に格納されてから何日でＰＬ上から消費され尽くすかの予測が可能となる。なお、格納期間２２の始点は格納期間２２の計算を行った時点（より正確には、混載候補商品までの総在庫数２０の計算の基となる在庫データ１１１が取得された時点）であり、終点は全ての混載候補商品１８１の保管エリア１０１からの搬出が終了する時点である。このため、例えばある二つの品目の商品について計算した格納期間２２の長さが近いことは、それらの品目の混載候補商品１８１の保管エリア１０１からの搬出が終了する時期が互いに近いことを示している。 The storage period 22 is the length of a period until all the mixed candidate products 181 are carried out from the storage area 101. By evaluating the storage period 22 as described above, if it is assumed that the mixed candidate product 181 is consumed at the same speed as the past results in accordance with the allocation order, what is stored in the storage area 101? It is possible to predict whether or not it will be consumed from the PL on a daily basis. The starting point of the storage period 22 is the time when the storage period 22 is calculated (more precisely, the time when the inventory data 111 that is the basis of the calculation of the total inventory number 20 up to the mixed candidate product is acquired), The end point is a point in time when all the mixed loading candidate products 181 are unloaded from the storage area 101. For this reason, for example, the length of the storage period 22 calculated for a product of two items is close, indicating that the time when the export of the mixed candidate product 181 of those items from the storage area 101 ends is close to each other. Yes.

　ステップＳ８（図５）：格納期間比較部１２４は、各混載候補商品１８１の格納期間２２とカテゴリ１７５と区分けルール１１３とを参照して、混載候補商品１８１をカテゴリ１７５および区分けルール１１３で区分けして、混載候補商品区分けリスト２３を生成する。すなわち、格納期間比較部１２４は、カテゴリ１７５ごとの各混載候補商品１８１を、格納期間２２と区分けルール１１３の格納期間幅１１３ｂとを照合して、該当する区分１１３ａに区分ける。混載候補商品区分けリスト２３の詳細は、図１４を参照して後述する。[Correction 04.08.2017 based on Rule 91]
Step S <b> 8 (FIG. 5): The storage period comparison unit 124 refers to the storage period 22 of each mixed loading candidate product 181, the category 175, and the classification rule 113, and classifies the mixed loading candidate product 181 by the category 175 and the classification rule 113. Thus, the mixed candidate product classification list 23 is generated. That is, the storage period comparison unit 124 classifies each mixed candidate product 181 for each category 175 into the corresponding section 113a by comparing the storage period 22 with the storage period width 113b of the classification rule 113. Details of the mixed candidate product classification list 23 will be described later with reference to FIG.

　ステップＳ９（図５）：混載組合せ決定部１２５は、混載候補商品区分けリスト２３、制約条件１１４および各混載候補商品１８１の混載対象物量１８３を参照して、ステップＳ８において同一区分に区分けられた混載候補商品１８１同士で、推奨の混載組合せを導出する。また、混載組合せ決定部１２５は、混載候補商品リスト１８の全混載候補商品１８１に対して推奨混載組合せを導出し終わったら、推奨混載組合せリスト１９を生成する。推奨混載組合せリスト１９の詳細は、図８を参照して後述する。また、ステップＳ９で実行される処理の詳細は、ステップＳ９１～Ｓ９４（図１６）を参照して後述する。[Correction 04.08.2017 based on Rule 91]
Step S9 (FIG. 5): The mixed loading combination determination unit 125 refers to the mixed loading candidate product classification list 23, the constraint condition 114, and the mixed loading target amount 183 of each mixed loading candidate product 181, and the mixed loading classified into the same classification in Step S8. A recommended mixed loading combination is derived between the candidate products 181. Further, the mixed combination combination determination unit 125 generates the recommended mixed combination list 19 after derivation of the recommended mixed combination for all the mixed candidate products 181 in the mixed candidate product list 18. Details of the recommended mixed combination list 19 will be described later with reference to FIG. Details of the processing executed in step S9 will be described later with reference to steps S91 to S94 (FIG. 16).

　入荷予定リスト１７は、入荷商品１７１、ロット名１７２、入荷予定日時１７３、入荷ＣＳ数１７４およびカテゴリ１７５から構成される。入荷商品１７１は、入荷する商品を識別する情報（例えば商品名）である。ロット名１７２は、入荷する商品のロットを識別する情報である。ロット管理がされていない倉庫ではロット名１７２は不要である。入荷予定日時１７３は、入荷する商品の入荷予定の日時である。入荷ＣＳ数１７４は、入荷する商品の数量を示す。入荷ＣＳ数１７４の単位は必ずしもＣＳである必要はなく、Ｐｃｓ数単位で表示されても良い。 The arrival schedule list 17 includes an arrival product 171, a lot name 172, a scheduled arrival date and time 173, an arrival CS number 174, and a category 175. The incoming product 171 is information (for example, a product name) for identifying the incoming product. The lot name 172 is information for identifying the lot of the product to be received. The lot name 172 is not necessary in a warehouse where lot management is not performed. The scheduled arrival date and time 173 is the scheduled date and time of arrival of the product to be received. The number of received CSs 174 indicates the quantity of products to be received. The unit of the received CS number 174 is not necessarily the CS, and may be displayed in the Pcs number unit.
　カテゴリ１７５は、図５を参照して説明した通り、ユーザが混載を許容する商品を指定するために与えられる情報である。図６の例では、１月２４日の１０：００に入荷する商品名「Ａ」、「Ｂ」および「Ｃ」で識別される３種の商品には同一のカテゴリ「１」が与えられ、１月２４日の１５：００に入荷する商品名「Ｄ」で識別される商品には上記と異なるカテゴリ「２」が与えられる。 As described with reference to FIG. 5, the category 175 is information given for the user to specify a product that allows mixed loading. In the example of FIG. 6, the same category “1” is given to the three types of products identified by the product names “A”, “B” and “C” received at 10:00 on January 24, A category “2” different from the above is given to the product identified by the product name “D” received at 15:00 on January 24th.
　例えば、同時に（又は近い時間帯に）入荷する商品は混載しやすいが、離れた時間帯に入荷する商品は、それらを混載しようとすると、先に入荷した商品をＰＬに積み付けてから、後で入荷する商品の入荷を待つ必要があるため、混載に適していない。このため、例えば、同時に（又は近い時間帯に）入荷する商品は同一のカテゴリに分類され、離れた時間帯に入荷する商品は異なるカテゴリに分類されてもよい。 For example, products that arrive at the same time (or at a close time) are likely to be mixed, but products that arrive at a distant time will be loaded after loading the products that have been received earlier into the PL. It is not suitable for mixed loading because it is necessary to wait for the arrival of the goods that arrive at. For this reason, for example, products that arrive at the same time (or at a close time) may be classified into the same category, and products that arrive at a distant time may be classified into different categories.
　図７は、本発明の実施例１の混載積付・格納指示装置１０が保持する混載候補商品リスト１８の例を示す説明図である。 FIG. 7 is an explanatory diagram showing an example of the mixed loading candidate product list 18 held by the mixed loading / storage instruction apparatus 10 according to the first embodiment of the present invention.
　混載候補商品リスト１８は、混載候補商品１８１、ロット名１７２、カテゴリ１７５、ＰＬ換算入荷物量１８２、混載対象物量１８３および混載対象ＣＳ数１８４から構成される。混載候補商品リスト１８は、ステップＳ４の処理を経て、入荷予定リスト１７の入荷商品１７１の中で混載候補商品１８１のみが抽出されて表示される。 The mixed loading candidate product list 18 is composed of a mixed loading candidate product 181, a lot name 172, a category 175, a PL converted package amount 182, a mixed loading target amount 183, and a mixed loading target CS number 184. The mixed loading candidate product list 18 is extracted and displayed from the received products 171 in the scheduled arrival list 17 through the process of step S4.
　具体的には、混載候補商品１８１は、混載候補商品を識別する情報（例えば商品名）である。ロット名１７２およびカテゴリ１７５は、それぞれ、入荷予定リスト１７に含まれるものに対応する。ＰＬ換算入荷物量１８２は、それぞれの商品について、式（１）によって計算される。混載対象物量１８３は、式（１）の計算結果の端数（すなわち小数点以下の）部分である。混載対象ＣＳ数１８４は、混載対象物量１８３をＣＳ数に換算した値である。 Specifically, the mixed loading candidate product 181 is information (for example, a product name) for identifying the mixed loading candidate product. The lot name 172 and the category 175 respectively correspond to those included in the arrival schedule list 17. The PL converted amount 182 is calculated for each product according to Equation (1). The mixed object amount 183 is a fractional part (that is, after the decimal point) of the calculation result of Expression (1). The mixed loading target CS number 184 is a value obtained by converting the mixed loading target amount 183 into the CS number.
　図８は、本発明の実施例１の混載積付・格納指示装置１０によって出力される推奨混載組合せリスト１９の例を示す説明図である。 FIG. 8 is an explanatory diagram showing an example of the recommended mixed loading combination list 19 output by the mixed loading / storage instruction apparatus 10 according to the first embodiment of the present invention.
　推奨混載組合せリスト１９は、混載候補商品１８１、ロット名１７２、入荷予定日時１７３、カテゴリ１７５、総入荷数１９１、推奨積付ＰＬ１９２、推奨積付物量１９３および予想格納期間２２から構成される。 The recommended mixed loading combination list 19 includes a mixed loading candidate product 181, a lot name 172, a scheduled arrival date and time 173, a category 175, a total arrival number 191, a recommended loading PL 192, a recommended loading amount 193, and an expected storage period 22.
　この中で、総入荷数１９１は、入荷予定リスト１７の入荷ＣＳ数１７４と混載候補商品リスト１８のＰＬ換算入荷物量１８２の両方を引用して表示する。 Among them, the total arrival number 191 displays both the arrival CS number 174 in the arrival schedule list 17 and the PL converted arrival amount 182 in the mixed candidate product list 18.
　推奨積付ＰＬ１９２は、混載候補商品１８１をどのＰＬに積付ければ良いかを表すもので、後述のステップＳ９４にて決定される。推奨積付物量１９３は、混載候補商品１８１の推奨積付ＰＬ１９２に対する積付け物量を、ＣＳ数と、それに相当するＰＬ数の両方で表したものである。 The recommended loading PL 192 indicates to which PL the mixed candidate product 181 should be loaded, and is determined in step S94 described later. The recommended load amount 193 represents the load amount for the recommended load PL 192 of the mixed loading candidate product 181 by both the CS number and the corresponding PL number.
　ここで、本発明の混載積付・格納指示装置１０は基本的には混載候補商品１８１の商品名とロット名１７２がいずれも同一である商品を複数のＰＬに分割して積み付けることはないものとする。すなわち、推奨積付物量１９３は、基本的には混載候補商品リスト１８の混載対象物量１８３と同一の値になる。これは、仮に複数ＰＬに分割することを許容すると、同一商品の同一ロット名が複数ロケに分散することになり、出荷作業者の負担および作業工数が増大するためである。 Here, the mixed loading / storage instruction apparatus 10 of the present invention basically does not divide and stack products having the same product name and lot name 172 of the mixed loading candidate products 181 into a plurality of PLs. Shall. That is, the recommended product amount 193 basically has the same value as the mixed object amount 183 in the mixed candidate product list 18. This is because if it is allowed to be divided into a plurality of PLs, the same lot name of the same product is distributed to a plurality of locations, increasing the burden on the shipping operator and the number of work steps.
　なお、推奨混載組合せリスト１９は、例えば推奨混載組合せリスト１９の各行に1枚ずつ、図８の各列の情報を印字したラベルを発行するような形態で出力されても良い。 Note that the recommended mixed combination list 19 may be output in a form in which, for example, one label is printed on each row of the recommended mixed combination list 19 and a label on which information of each column in FIG. 8 is printed.
　図９は、本発明の実施例１の混載積付・格納指示装置１０によって出力される推奨混載組合せリスト１９の別の例を示す説明図である。 FIG. 9 is an explanatory diagram showing another example of the recommended mixed loading combination list 19 output by the mixed loading / storage instruction apparatus 10 according to the first embodiment of the present invention.
　具体的には、図９は、推奨混載組合せリスト１９の各行をラベルに印字する例を示した図である。図９に示すラベルには、図８に示した推奨混載組合せリスト１９と同様の情報が印字される。ただし、１枚のラベルに、図８に示した推奨混載組合せリスト１９の１行分の混載候補商品名１８１、ロット名１７２、入荷予定日時１７３、カテゴリ１７５、推奨積付ＰＬ１９２、総入荷数１９１、予想格納期間２２および推奨積付物量１９３が印字される。 Specifically, FIG. 9 is a diagram showing an example in which each line of the recommended mixed combination list 19 is printed on a label. Information similar to the recommended mixed combination list 19 shown in FIG. 8 is printed on the label shown in FIG. However, on one label, the mixed loading candidate product name 181, lot name 172, scheduled arrival date and time 173, category 175, recommended loading PL 192, total number of arrivals 191 for one line of the recommended mixed loading combination list 19 shown in FIG. 8. The expected storage period 22 and the recommended load amount 193 are printed.
　この形態の場合は、ユーザが混載候補商品１８１の実物にそのラベルを貼ることで、積付作業員が間違えずにＰＬに商品を積付けられるという効果が期待できる。また、推奨混載組合せリスト１９を自動積付ロボットなどの機械が読込み可能な形で出力しておけば、積付作業を自動化することができる。 In the case of this form, it can be expected that the product can be loaded on the PL without the mistake of the loading worker by the user attaching the label to the actual mixed loading candidate product 181. If the recommended mixed combination list 19 is output in a form that can be read by a machine such as an automatic loading robot, the loading operation can be automated.
　図１０は、本発明の実施例１の混載積付・格納指示装置１０が保持する商品マスタ１１０の例を示す説明図である。 FIG. 10 is an explanatory diagram showing an example of the product master 110 held by the mixed loading / storage instruction device 10 according to the first embodiment of the present invention.
　商品マスタ１１０は、商品名１１０ａ、１ＰＬあたり積付可能ＣＳ数１１０ｂおよび商品属性１１０ｃから構成される。１ＰＬあたり積付可能ＣＳ数１１０ｂは、ＰＬ容積（すなわちＰＬ上に積み付けて良い商品の容積）を、各商品の１ＣＳ当たりの容積で割ることで算出できる。本実施例では１ＰＬが置かれる区画を１ロケとしていることから、１ＰＬあたり積付可能ＣＳ数１１０ｂは、１ロケに格納可能な商品の数量に相当する。 The product master 110 includes a product name 110a, a CS number 110b that can be loaded per 1PL, and a product attribute 110c. The CS number 110b that can be loaded per 1PL can be calculated by dividing the PL volume (that is, the volume of products that can be stacked on the PL) by the volume per 1CS of each product. In this embodiment, since the section where 1PL is placed is one location, the CS number 110b that can be loaded per 1PL corresponds to the quantity of products that can be stored in one location.
[規則91に基づく訂正 04.08.2017]　
　商品属性１１０ｃは商品の性質を記述するための列であり、商品属性１１０ｃの値としては、例えば要冷品（具体的には例えば生鮮食品および乳製品など）、危険品（具体的には例えば毒物など）などが考えられる。倉庫では、要冷品は空調エリア、危険品は入退室管理がなされた専用エリアなどに格納される。また、同一の商品属性１１０ｃ同士の商品を混載させることが一般的である。そのため後述のステップＳ９２およびＳ９３（図１６）では、まず商品属性１１０ｃが同一である商品同士で混載組合せを導出し、次に混載組合せが生成できなかった商品に対しては、制約条件１１４において混載可能（Ｔｒｕｅ）に指定されている商品属性１１０ｃの組合せに限って、混載組合せを生成する。なお、各商品１１０ａには基本的には何らかの商品属性１１０ｃを定義するものとするが、特に性質がない商品は「一般品」などの名称を定義しておけばよい。[Correction 04.08.2017 based on Rule 91]
The product attribute 110c is a column for describing the nature of the product, and the value of the product attribute 110c is, for example, a cold product (specifically, for example, fresh food or dairy product) or a dangerous product (specifically, for example, Toxic substances). In the warehouse, cool items are stored in an air-conditioning area, and dangerous items are stored in a dedicated area where entry / exit management is performed. Further, it is common to mix products with the same product attribute 110c. Therefore, in later-described steps S92 and S93 (FIG. 16), first, a mixed-load combination is derived between products having the same product attribute 110c, and then a product for which a mixed-load combination could not be generated is mixed-loaded in the restriction condition 114. A mixed combination is generated only for combinations of the product attributes 110c designated as “true”. Each product 110a basically defines some product attribute 110c, but a product having no particular property may be defined with a name such as “general product”.
　図１１は、本発明の実施例１の混載積付・格納指示装置１０が保持する在庫データ１１１の例を示す説明図である。 FIG. 11 is an explanatory diagram showing an example of inventory data 111 held by the mixed loading / storage instruction apparatus 10 according to the first embodiment of the present invention.
　在庫データ１１１は、保管エリア１０１の各ロケに保管されている在庫商品の商品名、ロット名および物量が分かれる情報であればよく、少なくともロケコード１１１ａ、商品名１１１ｂ、ロット名１１１ｃおよび在庫数（例えば在庫ＣＳ数１１１ｄ）が含まれていれば良い。但しロット管理がされていない倉庫では、ロット名１１１ｃは不要である。図１１に示す在庫データ１１１の例は、さらに、在庫数をＰＬ数に換算したＰＬ換算在庫数１１１ｅ、および、各ＰＬを識別するＰＬ名等の在庫ＰＬ１１１ｆを含む。 The stock data 111 may be information that separates the product name, lot name, and quantity of stock products stored in each location in the storage area 101. At least the location code 111a, the product name 111b, the lot name 111c, and the number of stocks ( For example, the inventory CS number 111d) may be included. However, the lot name 111c is unnecessary in a warehouse where lot management is not performed. The example of the inventory data 111 shown in FIG. 11 further includes a PL-converted inventory number 111e obtained by converting the inventory number into a PL number, and an inventory PL 111f such as a PL name for identifying each PL.
　図１２は、本発明の実施例１の混載積付・格納指示装置１０が保持する在庫消費実績１１２の例を示す説明図である。 FIG. 12 is an explanatory diagram showing an example of an inventory consumption record 112 held by the mixed loading / storage instruction apparatus 10 according to the first embodiment of the present invention.
[規則91に基づく訂正 04.08.2017]　
　在庫消費実績１１２は、保管エリア１０１からの在庫が消費される全パタン（例えば保管エリア１０１からのＣＳ出荷と、アクティブエリア１０２への補充の両方など）が網羅されていることが望ましい。在庫消費実績１１２には、少なくとも在庫消費が行われた日時１１２ａ、商品名１１２ｂおよび在庫消費ＣＳ数１１２ｃが含まれていれば良い。[Correction 04.08.2017 based on Rule 91]
The inventory consumption record 112 desirably covers all patterns in which the inventory from the storage area 101 is consumed (for example, both CS shipment from the storage area 101 and replenishment to the active area 102). The inventory consumption record 112 may include at least the date and time 112a when the inventory was consumed, the product name 112b, and the inventory consumption CS number 112c.
　図１３は、本発明の実施例１の混載積付・格納指示装置１０が算出する格納期間２２の考え方の説明図である。 FIG. 13 is an explanatory diagram of the concept of the storage period 22 calculated by the mixed loading / storage instruction apparatus 10 according to the first embodiment of the present invention.
　図１３は、Ａ、Ｂ、Ｃの３つの混載候補商品が存在すると仮定した場合のそれぞれの格納期間２２を示している。横軸は現在（本発明の装置を利用した日付）からの日数を表す。また、ステップＳ７によって算出した各混載商品の格納期間２２の終期（すなわち引当終了日）を図１３において黒丸で記す。図１３の破線部は、各混載候補商品よりも引当順序の早い別ロット名の同一商品の在庫ＰＬへの引当期間を表している。 FIG. 13 shows the respective storage periods 22 when it is assumed that three mixed candidate products A, B, and C exist. The horizontal axis represents the number of days from the present (date when the device of the present invention is used). Further, the end of the storage period 22 (that is, the allocation end date) of each mixed product calculated in step S7 is marked with a black circle in FIG. A broken line portion in FIG. 13 represents an allocation period for the inventory PL of the same product having a different lot name earlier in the allocation order than the respective mixed candidate products.
　図１４は、本発明の実施例１の混載積付・格納指示装置１０が保持する区分けルール１１３および混載積付・格納指示装置１０が生成する混載候補商品区分けリスト２３の例を示す説明図である。 FIG. 14 is an explanatory diagram illustrating an example of the classification rule 113 held by the mixed loading / storage instruction device 10 according to the first embodiment of the present invention and the mixed loading candidate product classification list 23 generated by the mixed loading / storage instruction device 10. is there.
　区分けルール１１３は、ステップＳ９で推奨混載組合せを導出するために必要なもので、格納期間２２をある日数の幅で区分けしたものである。区分けルール１１３の１行が１区分に当たる。 The sorting rule 113 is necessary for deriving the recommended mixed loading combination in step S9, and the storage period 22 is divided by a certain number of days. One line of the division rule 113 corresponds to one division.
　本実施例の混載積付・格納指示装置１０は、ステップＳ８にて、混載候補商品１８１の格納期間２２と、各区分１１３ａに指定された格納期間幅１１３ｂの日数の幅の上限および下限とを比較して、各混載候補商品１８１がどの区分１１３ａに該当するかを決定する。図１４の例では、混載対象商品の商品名２３ａに記載されているように、格納期間２２がそれぞれ５日、１０日、４日である商品Ａ、Ｂ、Ｃが、それぞれ番号２、３、２の区分に決まったことを示している。混載候補商品区分けリスト２３は、カテゴリ１７５ごとに作成される。 In step S8, the mixed loading / storage instruction apparatus 10 according to the present embodiment determines the storage period 22 of the mixed loading candidate product 181 and the upper and lower limits of the number of days of the storage period width 113b specified for each section 113a. In comparison, it is determined which category 113a each mixed candidate product 181 corresponds to. In the example of FIG. 14, as described in the product name 23a of the product to be mixed, the products A, B, and C whose storage periods 22 are 5 days, 10 days, and 4 days are numbers 2, 3, and It is shown that it was decided in 2 categories. A mixed candidate product classification list 23 is created for each category 175.
　ここで区分けルール１１３に指定する区分１１３ａの数と、各区分に指定する格納期間幅１１３ｂの値は任意であるが、区分１１３ａ間で指定した格納期間幅１１３ｂが重複しないようにする。また、区分１１３ａの数が多過ぎると一つの区分に複数の商品が分類されにくくなるため、混載組合せが導出されにくくなる。一方、区分１１３ａの数が少な過ぎると格納期間が異なる商品同士が混載されやすくなり、本発明の効果が発揮されない懸念がある。そのため、例えば、各商品の格納期間の分布を調べて、その分布の統計値（平均値、中央値、最頻値、分散、標準偏差など）を加味して区分１１３ａの数と格納期間幅１１３ｂを定めることが望ましい。 Here, the number of the divisions 113a designated in the division rule 113 and the value of the storage period width 113b designated in each division are arbitrary, but the storage period widths 113b designated between the divisions 113a are not overlapped. In addition, if the number of the sections 113a is too large, it is difficult for a plurality of products to be classified into one section, so that it is difficult to derive a mixed combination. On the other hand, if the number of sections 113a is too small, products with different storage periods are likely to be mixed and there is a concern that the effects of the present invention will not be exhibited. Therefore, for example, the distribution of the storage period of each product is examined, and the number of the divisions 113a and the storage period width 113b are added by taking into account the statistical values (average value, median value, mode value, variance, standard deviation, etc.) of the distribution. It is desirable to define
　なお、本実施例では上記のように格納期間を複数の区分に分けて同一の区分に属する格納期間を有する商品を混載候補としているが、これは、格納期間の長さが近い（すなわち混載候補商品の搬出が終了する時期が近い）商品の組合せを特定する方法の一例である。このような区分を利用することによって、格納期間の長さに応じた商品の分類を簡単に行うことができる。しかし、混載積付・格納指示装置１０は、上記以外の方法で格納期間の長さが近い商品の組合せを特定し、それらを混載候補としてもよい。 In the present embodiment, as described above, the storage period is divided into a plurality of sections, and products having storage periods belonging to the same section are used as mixed loading candidates. This is an example of a method for specifying a combination of products (which is close to the time when the delivery of the products ends). By using such a classification, it is possible to easily classify products according to the length of the storage period. However, the mixed loading / storage instruction apparatus 10 may identify combinations of products having a storage period close to the length by a method other than the above, and may use them as mixed loading candidates.
　図１５は、本発明の実施例１の混載積付・格納指示装置１０が保持する制約条件１１４の例を示す説明図である。 FIG. 15 is an explanatory diagram illustrating an example of the constraint condition 114 held by the mixed loading / storage instruction apparatus 10 according to the first embodiment of this invention.
　図１５の例では、制約条件１１４として、商品属性１（１１４ａ）、商品属性２（１１４ｂ）、および混載可能１１４ｃが記述される。ここで商品属性１（１１４ａ）および商品属性２（１１４ｂ）は商品マスタ１１０の商品属性１１０ｃと同一の文言（値）を記載するものとする。図１５の例では、一般品、要冷品、危険品の三種類が存在する倉庫で、それぞれの組合せパタン（要冷品と一般品、要冷品と危険品、危険品と一般品）について、混載を許容するかを混載可能１１４ｃにＴＲＵＥ／ＦＡＬＳＥで記述する。 In the example of FIG. 15, the product attribute 1 (114a), the product attribute 2 (114b), and the loadable 114c are described as the constraint condition 114. Here, product attribute 1 (114a) and product attribute 2 (114b) describe the same wording (value) as product attribute 110c of product master 110. In the example of FIG. 15, there are three types of warehouses, general goods, refrigerated goods, and dangerous goods. For each combination pattern (cooled goods and general goods, refrigerated goods and dangerous goods, dangerous goods and general goods) Whether to allow mixed loading is described in TRUE / FALSE in the mixed loading possible 114c.
[規則91に基づく訂正 04.08.2017]　
　図１５の例では各行ともＦＡＬＳＥに指定されており、いずれの組合せパタンとも混載は許容されないことを意味する。しかし、例えば保管エリアの物量が多い場合には、一般品と要冷品を混載させて要冷エリアに格納することも考えられる。そのような場合には、要冷品と一般品の組合せの行の混載可能１１４ｃをＴＲＵＥに書き換えれば、要冷品と一般品の混載組合せが導出できる。[Correction 04.08.2017 based on Rule 91]
In the example of FIG. 15, each row is designated as FALSE, which means that any combination pattern is not allowed to be mixed. However, for example, when there is a large amount of material in the storage area, it is conceivable that a general product and a cold-required product are mixed and stored in the cold-required area. In such a case, if the mixed mountable 114c in the row of the combination of the cold-required product and the general product is rewritten to TRUE, the mixed combination of the cool-required product and the general product can be derived.
　図１６は、本発明の実施例１の混載積付・格納指示装置１０がステップＳ９において実行する詳細な処理を示すフローチャートである。以下、各ステップについて説明する。 FIG. 16 is a flowchart showing detailed processing executed in step S9 by the mixed loading / storage instruction apparatus 10 according to the first embodiment of the present invention. Hereinafter, each step will be described.

　ステップＳ９１（図１６）：混載組合せ決定部１２５は、各カテゴリ１７５の混載候補商品区分けリスト２３の中で、同一区分に区分けられた混載対象商品の商品名２３ａ、それぞれの商品名に対応する混載対象物量１８３、および商品属性１１０ｃを取得する。[Correction 04.08.2017 based on Rule 91]
Step S91 (FIG. 16): The mixed loading combination determination unit 125 includes the product names 23a of the mixed loading target products classified into the same category in the mixed candidate product classification list 23 of each category 175, and the mixed loading corresponding to each product name. The object amount 183 and the product attribute 110c are acquired.
[規則91に基づく訂正 04.08.2017]　
　ステップＳ９２（図１６）：混載組合せ決定部１２５は、各カテゴリ１７５の混載候補商品区分けリスト２３に登録された混載対象商品の商品名２３ａによって識別される商品（以下、単に商品２３ａとも記載する）のうち、区分１１３ａが共通し、かつ、商品属性１１０ｃも共通する複数の商品２３ａの組合せを抽出し、抽出した各商品２３ａの混載対象物量１８３の総和が１ＰＬ以下になる範囲で、混載ＰＬに積み付けられる商品の組合せを生成する。これによって、ロケの回転率の向上に寄与し、かつ、実際に積み付け可能な商品の組合せが生成される。[Correction 04.08.2017 based on Rule 91]
Step S92 (FIG. 16): The mixed combination determination unit 125 is a product identified by the product name 23a of the mixed target product registered in the mixed candidate product classification list 23 of each category 175 (hereinafter also simply referred to as a product 23a). Among them, the combination of a plurality of products 23a having the same category 113a and the same product attribute 110c is extracted, and the combined load quantity 183 of each extracted product 23a is within the range of 1PL or less in the mixed load PL. Generate a combination of products to be stacked. As a result, a combination of commodities that contributes to an improvement in location rotation rate and can be actually stacked is generated.
　ここで、混載ＰＬの組合せの生成方法は特に問わないが、倉庫現場では格納ＰＬの数はなるべく少ない方が良いと考えられることから、例えばナップザック問題などのアルゴリズムを用いて、生成される混載ＰＬ数を最小化する混載組合せ生成を行うと良い。 Here, the generation method of the mixed-PL combination is not particularly limited. However, since it is considered that the number of stored PLs should be as small as possible at the warehouse site, the mixed-PL generated using, for example, an algorithm such as a knapsack problem. It is preferable to perform mixed combination generation that minimizes the number.
　但し、１ＰＬに積付ける商品（ＳＫＵ）数が多過ぎると、ある商品ＳＫＵの上に別のＳＫＵの商品を積み付けるような不安定な荷姿となって格納作業時に運搬がしづらくなったり、出荷作業時の誤ピックの要因となったりする。そのような事態を避けるために、１ＰＬに積付可能なＳＫＵ数の制限を設けて、その範囲内でＰＬに商品を積み付けるように商品の組合せを決定しても良い。 However, if there are too many products (SKUs) to be loaded on 1PL, it will become an unstable package like loading products of another SKU on one product SKU, making it difficult to carry during storage work, It may be a cause of erroneous picking during shipping work. In order to avoid such a situation, a limit on the number of SKUs that can be loaded on 1PL is provided, and a combination of products may be determined so that products are loaded on the PL within that range.

　ステップＳ９３（図１６）：混載組合せ決定部１２５は、各カテゴリ１７５の混載候補商品区分けリスト２３の商品２３ａであって、ステップＳ９２で混載組合せに含まれなかった商品のうち、区分１１３ａが共通し、かつ、その商品の商品属性１１０ｃと制約条件１１４を参照して、混載可能１１４ｃの列がＴｒｕｅに指定されている組合せに限定して、混載対象物量１８３の総和が１ＰＬ以下になる範囲で混載組合せを生成する。[Correction 04.08.2017 based on Rule 91]
Step S93 (FIG. 16): The mixed loading combination determination unit 125 has a common category 113a among the products 23a in the mixed loading candidate product classification list 23 of each category 175 and not included in the mixed loading combination in Step S92. In addition, referring to the product attribute 110c of the product and the constraint condition 114, only the combination in which the column of the mountable 114c is specified as True is combined, and the combined load amount 183 is mixed within a range of 1PL or less. Generate a combination.
　図１４の例では、区分１１３ａの値「２」に対応する混載対象商品の商品として商品Ａおよび商品Ｃが登録されている。これらの商品の混載対象物量１８３はいずれも０．５ＰＬであるため、それらの合計は１ＰＬとなる。また、それらの商品属性１１０ｃはいずれも「一般品」である。このため、混載組合せ決定部１２５は、ステップＳ９２において、商品Ａと商品Ｃの組合せを混載組合せとして生成することができる。 In the example of FIG. 14, a product A and a product C are registered as products of the mixed loading target product corresponding to the value “2” of the category 113a. Since the mixed load amount 183 of these commodities is 0.5 PL, the total of them is 1 PL. In addition, those product attributes 110c are all “general products”. For this reason, the mixed loading combination determination unit 125 can generate a combination of the products A and C as a mixed loading in step S92.
　上記の例において、仮に、商品Ａと商品Ｃの商品属性１１０ｃが異なっていたとすると、それらの組合せはステップＳ９２では混載組合せとして生成されない。しかし、それらの商品属性１１０ｃの組合せに対応する混載可能１１４ｃの値がＴｒｕｅであれば、混載組合せ決定部１２５は、ステップＳ９３において、それらの組合せを混載組合せとして生成することができる。 In the above example, assuming that the product attributes 110c of the product A and the product C are different, those combinations are not generated as a mixed combination in step S92. However, if the value of the mountable 114c corresponding to the combination of the product attributes 110c is True, the combined combination determination unit 125 can generate the combination as a combined combination in step S93.

　ステップＳ９４（図１６）：混載組合せ決定部１２５は、ステップＳ９２およびＳ９３のいずれかで同一のＰＬに積付けるべきと判定した混載候補商品２３ａに対して、同一の推奨積付ＰＬ名１９２を付与する。[Correction 04.08.2017 based on Rule 91]
Step S94 (FIG. 16): The mixed loading combination determination unit 125 gives the same recommended loading PL name 192 to the mixed loading candidate product 23a determined to be loaded on the same PL in any of steps S92 and S93. To do.
　図１７Ａおよび図１７Ｂは、本発明の実施例１の効果を説明する図である。 FIG. 17A and FIG. 17B are diagrams for explaining the effect of the first embodiment of the present invention.
　図１７Ａおよび図１７Ｂに示すグラフの横軸は格納期間、縦軸はＰＬ上の商品のＣＳ数を表している。図１７Ａは、本発明を用いずに仮に格納期間５日の商品Ａと、格納期間１０日の商品Ｂを混載させた混載ＰＬの、保管エリアにおける在庫の減り方を現している。図１７Ａでは、商品Ａが消費されてから商品Ｂが消費されるまでの５日間、商品ＢがＰＬ上に残り続けるため、この５日間は当該ＰＬが置かれているロケが歯欠け（低充填率）ロケになってしまい、別のＰＬをこのロケに格納することが難しい。 17A and 17B, the horizontal axis represents the storage period, and the vertical axis represents the CS number of products on the PL. FIG. 17A shows how to reduce the stock in the storage area of the mixed load PL in which the product A for the storage period 5 days and the product B for the storage period 10 days are mixed without using the present invention. In FIG. 17A, since the product B remains on the PL for 5 days from the consumption of the product A to the consumption of the product B, the location where the PL is placed is missing teeth (low filling) for 5 days. It is difficult to store another PL in this location.
　ここで、歯欠け（低充填率）ロケとは、商品が疎らなロケ、すなわち、積み付け可能な数量に満たない数量の商品が積み付けられたＰＬが置かれているロケである。 Here, the missing tooth (low filling rate) location is a location where a product is sparse, that is, a location where a product with a quantity less than the quantity that can be stacked is placed.
　なお、歯欠け（低充填率）ロケに対しては、実施例２で示すような詰込みの格納を行うことはできるが、この場合は、詰込み格納をしたい商品を格納済の在庫ＰＬに移し変えて、かつそれまで格納商品を載せていたＰＬを片付けるなどの追加作業が発生する。また、発明が解決しようとする課題で述べた通り、棚寄せ作業を行えば歯欠け（低充填率）ロケを除去できるが、棚寄せ作業を日々行うことは難しい。そのため、入庫格納段階で、格納期間の近い商品同士の混載組合せを行うことで、歯欠け（低充填率）ロケの発生を抑えることが望ましい。本実施例によれば、入庫格納段階で、歯欠け（低充填率）ロケの発生を抑えることができる。 In addition, although it is possible to store clogging as shown in the second embodiment for a missing tooth (low filling rate) location, in this case, a product to be stored is stored in the stored inventory PL. Additional work, such as moving away and clearing up the PL that had been storing the stored goods, will occur. In addition, as described in the problem to be solved by the invention, if the shelving operation is performed, the tooth chipping (low filling rate) location can be removed, but it is difficult to perform the shelving operation every day. For this reason, it is desirable to suppress the occurrence of missing teeth (low filling rate) location by performing a mixed combination of commodities with similar storage periods at the storage stage. According to the present embodiment, it is possible to suppress the occurrence of missing teeth (low filling rate) location at the storage and storage stage.
　図１７Ｂは、本発明を用いて、格納期間５日の商品Ａと格納期間６日の商品Ｃを混載させた場合の在庫の減り方を表している。この場合の歯欠け（低充填率）ロケ発生期間は1日に削減される。これによって、無駄な歯欠ロケ発生期間を抑えることができ、保管エリアの間口の利用効率および回転率が向上する。 FIG. 17B shows how the inventory is reduced when the product A with the storage period of 5 days and the product C with the storage period of 6 days are mixedly loaded using the present invention. In this case, the missing tooth (low filling rate) location occurrence period is reduced to one day. As a result, it is possible to suppress the generation period of useless tooth missing and improve the utilization efficiency and rotation rate of the frontage of the storage area.
　また、格納作業を行う作業員は、本装置が出力する推奨混載組合せリスト１９の予想格納期間２２を参照して、予想格納期間２２が短い商品同士の混載ＰＬを出荷作業のしやすいロケ（例：出荷バース近くの１段目の棚）に、予想格納期間２２が長い商品同士の混載ＰＬを、出荷作業はしづらいが移動棚などの保管効率を重視したロケに格納することで、出荷作業のしやすいロケは常に回転率が高い状態を保つことができ、出荷作業全体の効率の向上も期待できる。 In addition, the worker who performs the storage work refers to the expected storage period 22 in the recommended mixed combination list 19 output by the present apparatus, and the location (for example, the mixed PL of products having a short expected storage period 22 can be easily shipped. : The first stage shelf near the shipping berth) is shipped by storing the mixed load PL of products with a long expected storage period 22 in a location that is difficult to ship but places importance on storage efficiency such as a moving shelf. Locations that are easy to wear can always maintain a high rotation rate, and an improvement in overall shipping efficiency can also be expected.
　次に、本発明の実施例２について説明する。以下に説明する相違点を除き、実施例２のシステムの各部は、図１～図１７に示された実施例１の同一の符号を付された各部と同一の機能を有するため、それらの説明は省略する。 Next, Example 2 of the present invention will be described. Except for the differences described below, each part of the system of the second embodiment has the same functions as the parts denoted by the same reference numerals in the first embodiment shown in FIG. 1 to FIG. Is omitted.
　実施例１では入荷段階で１ＰＬに満たない端数の入荷ＳＫＵ（１商品、１ロット）を混載させてから格納する場合について説明した。しかし、実際の倉庫業務では、１ＰＬに満たない物量の入荷商品を、保管エリアの在庫ＰＬに詰め込む場合がある。このような格納を詰込み格納と称する。 In the first embodiment, a case has been described in which a stock SKU (one product, one lot) of less than 1 PL is mixed and stored at the arrival stage. However, in actual warehousing operations, there are cases where incoming products with a quantity less than 1PL are packed into the inventory PL in the storage area. Such storage is referred to as packed storage.
　この場合も、詰込み格納を行う商品と、在庫ＰＬ上の商品（すなわち、既に積み付けられ、かつ、まだ消費されていない商品）との混載組合せと考えることができ、実施例１の場合と同様に、格納期間２２の似通った商品同士を混載させることで、実施例１と同様の効果を得ることができる。 In this case as well, it can be considered as a mixed combination of the product to be stored and the product on the inventory PL (that is, the product already loaded and not yet consumed). Similarly, the effect similar to Example 1 can be acquired by carrying together the goods with similar storage period 22 between.
　すなわち、実施例２では、実施例１と同様に計算された混載対象物量１８３が示す数量の混載候補商品１８１（ステップＳ４）に加えて、格納可能な数量に満たない数量の商品が格納されているロケ（より詳細には、積み付け可能な数量に満たない数量の商品が積み付けられたＰＬが置かれているロケ）に格納されている商品が、他の品目の商品と混載して保管エリア１０１に格納するか否かを決定する対象となる。 That is, in the second embodiment, in addition to the number of mixed loading candidate products 181 (step S4) indicated by the mixed loading target amount 183 calculated in the same manner as in the first embodiment, the number of products less than the storable quantity is stored. The product stored in the location (more specifically, the location where the PL with the quantity less than the quantity that can be loaded is placed) is stored together with the goods of other items It is a target for determining whether to store in the area 101.
　本実施例の混載積付・格納指示装置１０が実行する処理は、以下に説明する変更点を除いて、図５および図１６に示す通りである。 The processing executed by the mixed loading / storage instruction device 10 of the present embodiment is as shown in FIGS. 5 and 16 except for the changes described below.

　ステップＳ３（図５）：混載候補抽出部１２０は、入力部１３のモード選択欄５０１において詰込み格納指示５０１ｂが指定され、入荷予定リスト名入力欄５０２において入荷予定リスト１７が入力され、かつ実行ボタン５０３を介して実行指示が入力された場合、ステップＳ４に進む。実行指示がない場合は、入力待ちを継続する。ここで、入荷予定リスト１７のカテゴリ１７５は実施例２においては必要ない。[Correction 04.08.2017 based on Rule 91]
Step S3 (FIG. 5): The mixed loading candidate extraction unit 120 designates the clogging storage instruction 501b in the mode selection column 501 of the input unit 13, inputs the scheduled arrival list 17 in the scheduled arrival list name input column 502, and executes it. When an execution instruction is input via the button 503, the process proceeds to step S4. If there is no execution instruction, the input wait is continued. Here, the category 175 of the arrival schedule list 17 is not necessary in the second embodiment.

　ステップＳ５（図５）：総在庫数計算部１２１は、混載候補商品までの総在庫数２０を算出するとともに、在庫データ１１１上の在庫ＰＬ１１１ｆに対しても同様に、ロケに対応する各商品１１１ｂに対して、在庫ＰＬの商品までの総在庫数（図示省略）を算出する。言い換えると、ここで算出される在庫ＰＬの商品までの総在庫数は、在庫ＰＬに積み付けられている商品と同一名の（すなわち同一品目の）商品を、引当順序に従って保管エリア１０１から搬出していった場合に、在庫ＰＬに積み付けられている全ての商品の搬出が終了するまでに搬出される当該商品の数に相当する。[Correction 04.08.2017 based on Rule 91]
Step S5 (FIG. 5): The total inventory quantity calculation unit 121 calculates the total inventory quantity 20 up to the mixed loading candidate product, and similarly, each product 111b corresponding to the location for the inventory PL 111f on the inventory data 111. On the other hand, the total number of stocks (not shown) up to the product of the stock PL is calculated. In other words, the total number of stocks up to the product of the stock PL calculated here is the product having the same name (that is, the same item) as the product stacked in the stock PL, and is carried out from the storage area 101 according to the allocation order. In this case, this corresponds to the number of products to be carried out before the carrying out of all the products stacked in the stock PL is completed.

　ステップＳ７（図５）：格納期間算出部１２３は、各混載候補商品の格納期間２２および各在庫ＰＬの格納期間２２ｂを式（４）式（５）によって算出する。[Correction 04.08.2017 based on Rule 91]
Step S7 (FIG. 5): The storage period calculation unit 123 calculates the storage period 22 of each mixed candidate product and the storage period 22b of each inventory PL by using the expressions (4) and (5).
混載候補商品の格納期間２２＝混載候補商品までの総在庫数２０／平均在庫消費数２１　式（４） Mixed loading candidate product storage period 22 = total inventory number 20 / average inventory consumption number 21 until mixed loading candidate product Formula (4)
在庫ＰＬの格納期間２２ｂ＝在庫ＰＬの商品までの総在庫数／平均在庫消費数２１　式（５） Inventory PL storage period 22b = total number of inventory up to products in inventory PL / average inventory consumption number 21 Formula (5)
　ここで、仮に在庫ＰＬが混載されている場合、在庫ＰＬの格納期間２２ｂは在庫ＰＬ上の各商品１１１ｂについて計算した格納期間の最大値を採用する。 Here, if the inventory PL is mixedly loaded, the storage period 22b of the inventory PL adopts the maximum value of the storage period calculated for each product 111b on the inventory PL.

　ステップＳ８（図５）：格納期間比較部１２４は、混載候補商品の格納期間２２と在庫ＰＬの格納期間２２ｂと区分けルール１１３とを参照して、混載候補商品１８１と在庫ＰＬとを区分けルール１１３で区分けして、混載候補商品・在庫ＰＬ区分けリスト３３を生成する。混載候補商品・在庫ＰＬ区分けリスト３３の詳細は、図２０を参照して後述する。[Correction 04.08.2017 based on Rule 91]
Step S8 (FIG. 5): The storage period comparison unit 124 refers to the mixed candidate product storage period 22, the inventory PL storage period 22b, and the classification rule 113, and classifies the mixed candidate product 181 and the inventory PL. The mixed candidate product / stock PL classification list 33 is generated. Details of the mixed candidate product / stock PL sorting list 33 will be described later with reference to FIG.

　ステップＳ９（図５）：混載組合せ決定部１２５は、混載候補商品・在庫ＰＬ区分けリスト３３、制約条件２１４（図１９を参照して後述する）、混載候補商品１８１の混載対象物量１８３および在庫ＰＬのＰＬ換算在庫数１１１ｅを参照して、混載候補商品１８１の推奨格納先ロケ２９２を導出し、詰込み格納推奨リスト２９を生成する。ステップＳ９の詳細はステップＳ９１～Ｓ９４で説明する。ここで、在庫ＰＬが混載されている場合は、ＰＬ換算在庫数１１１ｅは、同一在庫ＰＬ上の各商品のＰＬ換算在庫数１１１ｅの総和を取る。[Correction 04.08.2017 based on Rule 91]
Step S9 (FIG. 5): The mixed loading combination determination unit 125, the mixed loading candidate product / stock PL classification list 33, the constraint condition 214 (to be described later with reference to FIG. 19), the mixed loading target amount 183 and the stock PL of the mixed loading candidate product 181. The recommended storage destination location 292 of the mixed candidate product 181 is derived by referring to the PL converted stock quantity 111e, and the stuffing storage recommendation list 29 is generated. Details of step S9 will be described in steps S91 to S94. Here, when the stock PL is mixedly loaded, the PL-converted inventory number 111e is the sum of the PL-converted inventory numbers 111e of each product on the same inventory PL.

　ステップＳ１０（図５）：出力部１４は、詰込み格納推奨リスト２９を出力する。出力が終わったら、ステップＳ２に戻り再びユーザ指示の入力待ちを行う。ここで詰込み格納推奨リスト２９は、実施例１の図９のように、１行ずつラベルで発行されても良い。また、自動搬送ロボットのような機械が読み込める形式で出力しておけば、詰込み格納作業を機械化・自動化することができ、倉庫内の格納作業の効率化が図れる。[Correction 04.08.2017 based on Rule 91]
Step S10 (FIG. 5): The output unit 14 outputs a clogging storage recommendation list 29. When the output is completed, the process returns to step S2 and waits for the input of the user instruction again. Here, as shown in FIG. 9 of the first embodiment, the stuffing storage recommendation list 29 may be issued for each line with a label. Also, if the output is read in a format that can be read by a machine such as an automatic transfer robot, the packing operation can be mechanized and automated, and the storage operation in the warehouse can be made more efficient.

Step S91 (FIG. 16): The mixed loading combination determination unit 125 includes the product names 33a of the mixed loading candidate products classified into the same category 113a in the mixed loading candidate product / stock PL classification list 33, and the mixed loading corresponding to the respective product names. Object quantity 183, product attribute 110c, storage location code 111a of inventory PL 33b divided into the same category, location attribute 115b of the storage location identified by the location code, and PL converted inventory quantity 111e of the storage location To get.

　ステップＳ９２（図１６）：混載組合せ決定部１２５は、混載候補商品・在庫ＰＬ区分けリスト３３に登録された混載候補商品の商品名３３ａによって識別される各商品（以下、単に商品３３ａとも記載する）に対して、商品属性２１４ａ、同一区分の在庫ＰＬ３３ｂの格納先ロケコード１１１ａに対応するロケ属性１１５ｂ、および、制約条件２１４を参照して、制約条件２１４の格納可能２１４ｃの列がＴｒｕｅに指定されている組合せに限定して、各商品３３ａの混載対象物量１８３と在庫ＰＬ３３ｂのＰＬ換算在庫数１１１ｅとの総和が１ＰＬ以下になる範囲で、各商品３３ａと在庫ＰＬ３３ｂの混載組合せを生成する。ここで各商品３３ａに組合わされた在庫ＰＬの格納先ロケコード１１１ａの値が、各商品３３ａの推奨ロケ２９２となる。[Correction 04.08.2017 based on Rule 91]
Step S92 (FIG. 16): The mixed loading combination determining unit 125 identifies each product (hereinafter, also simply referred to as a product 33a) identified by the product name 33a of the mixed loading candidate product registered in the mixed loading candidate product / stock PL classification list 33. On the other hand, referring to the product attribute 214a, the location attribute 115b corresponding to the storage location code 111a of the inventory PL 33b of the same category, and the constraint condition 214, the column of the storable 214c of the constraint condition 214 is designated as True. The combination combination of each product 33a and the stock PL 33b is generated in such a range that the sum of the mixed load quantity 183 of each product 33a and the PL converted stock quantity 111e of the stock PL 33b is 1PL or less. Here, the value of the storage location code 111a of the inventory PL combined with each product 33a becomes the recommended location 292 of each product 33a.

　ステップＳ９３（図１６）：混載組合せ決定部１２５は、ステップＳ９２で混載組合せに含まれなかった商品３３ａおよび在庫ＰＬ３３ｂに対して、商品３３ａの商品属性２１４ａと、同一区分の在庫ＰＬの格納先ロケコード１１１ａに対応するロケ属性１１５ｂと制約条件２１４を参照して、制約条件２１４の緩和可能２１４ｄの列がＴｒｕｅに指定されている組合せに限定して、商品２３ａの混載対象物量１８３と在庫ＰＬのＰＬ換算在庫数１１１eの総和が１ＰＬ以下になる範囲で各商品２３ａと在庫ＰＬ３３ｂの混載組合せを生成する。ここで各商品２３ａに組合わされた在庫ＰＬ３３ｂの格納先ロケコード１１１ａの値が、商品２３ａの推奨ロケ２９２となる。[Correction 04.08.2017 based on Rule 91]
Step S93 (FIG. 16): The mixed loading combination determination unit 125 stores the product attribute 214a of the product 33a and the storage location of the stock PL of the same category for the product 33a and the stock PL 33b that are not included in the mixed loading combination in Step S92. With reference to the location attribute 115b corresponding to the code 111a and the constraint condition 214, only the combinations in which the column of the relaxable 214d of the constraint condition 214 is designated as True, the mixed load quantity 183 and the inventory PL of the product 23a are limited. A mixed combination of each product 23a and stock PL33b is generated within a range where the total of the PL converted stock quantity 111e is 1PL or less. Here, the value of the storage location code 111a of the stock PL 33b combined with each product 23a becomes the recommended location 292 of the product 23a.
　ここで、実施例１と同様に、１ＰＬに積付けるＳＫＵ数に制限を設けて、その範囲内で在庫ＰＬ３３ｂに混載候補商品３３ａを積み付けるように商品の組合せを決定しても良い。それによって、格納作業時の運搬・格納時の安全確保および出荷作業時の誤ピックのリスク低下が図れる。 Here, similarly to the first embodiment, the number of SKUs to be loaded on 1PL may be limited, and the combination of products may be determined so that the mixed loading candidate product 33a is loaded on the stock PL 33b within the range. As a result, it is possible to ensure safety during transportation and storage during storage operations and to reduce the risk of erroneous picking during shipping operations.

　図１８は、本発明の実施例２の混載積付・格納指示装置１０が保持するロケマスタ１１５の例を示す説明図である。 FIG. 18 is an explanatory diagram showing an example of the location master 115 held by the mixed loading / storage instruction apparatus 10 according to the second embodiment of the present invention.
　ロケマスタ１１５は、各ロケコード１１５ａに対して、ロケ属性１１５ｂを定義する。ロケ属性１１５ｂの値と、ロケに保管できる商品の属性との関係は、図１９に示す制約条件２１４によって制約される。 The location master 115 defines a location attribute 115b for each location code 115a. The relationship between the value of the location attribute 115b and the attribute of the product that can be stored in the location is restricted by the constraint condition 214 shown in FIG.
　図１９は、本発明の実施例２の混載積付・格納指示装置１０が保持する制約条件２１４の例を示す説明図である。 FIG. 19 is an explanatory diagram illustrating an example of the constraint condition 214 held by the mixed loading / storage instruction apparatus 10 according to the second embodiment of the present invention.
　制約条件２１４は、商品属性２１４ａ、ロケ属性２１４ｂ、格納可能２１４ｃ、および緩和可能２１４ｄから構成される。ここで、格納可能２１４ｃの列は、商品属性２１４ａの値が示す属性の商品を、ロケ属性２１４ｂの値が示す属性のロケに格納可能かどうかを示す値（ＴＲＵＥ：格納可能、ＦＡＬＳＥ：格納不可）を保持する。緩和可能２１４ｄの列は、各商品属性２１４ａの商品の格納先ロケ（ロケ属性２１４ｂ）に優先度の強弱をつけるために用いる。例えば、商品属性２１４ａが「一般品」である商品の格納先ロケを、まずはロケ属性２１４ｂが「一般品」であるロケの中から探し、その中で格納先がなければ、次にロケ属性２１４ｂが「要冷品」であるロケの中から格納先ロケを探したい場合がある。そのような場合、図１９の１行目のように、「商品属性２１４ａ＝一般品」および「ロケ属性２１４ｂ＝一般品」に対応して「格納可能２１４ｃ＝ＴＲＵＥ」を記述し、さらに、２行目のように、「商品属性２１４ａ＝一般品」および「ロケ属性２１４ｂ＝要冷品」に対応して「格納可能２１４ｃ＝ＦＡＬＳＥ」および「緩和可能２１４ｄ＝ＴＲＵＥ」を記述しておけば良い。 The constraint condition 214 includes a product attribute 214a, a location attribute 214b, a storable 214c, and a relaxable 214d. Here, the column of storable 214c is a value (TRUE: storable, FALSE: unstorable) indicating whether or not the product of the attribute indicated by the value of the product attribute 214a can be stored in the location of the attribute indicated by the value of the location attribute 214b. ). The column of 214d that can be relaxed is used to give priority to the storage location of the product of each product attribute 214a (location attribute 214b). For example, a storage location of a product whose product attribute 214a is “general product” is first searched from locations where the location attribute 214b is “general product”, and if there is no storage destination, the location attribute 214b is next searched. There is a case where it is desired to search for a storage location from among locations that are “requiring cold products”. In such a case, “storeable 214c = TRUE” is described corresponding to “product attribute 214a = general product” and “location attribute 214b = general product” as shown in the first line of FIG. Like the line, “storable 214c = FALSE” and “relaxable 214d = TRUE” should be described corresponding to “product attribute 214a = general product” and “location attribute 214b = required product”. .

　混載候補商品・在庫ＰＬ区分けリスト３３は、区分１１３ａ、格納期間幅１１３ｂ、混載候補商品（商品名）３３ａおよび在庫ＰＬ３３ｂから構成される。図２０の例は、区分１１３ａの値「２」に対応する格納期間幅１１３ｂは「３日～７日」であり、この区分の混載候補商品３３ａとして「Ａ」、「Ｃ」が、在庫ＰＬ３３ｂとして「ＰＬ１１」、「ＰＬ１３」が登録されている。これは、入荷商品から混載候補として抽出された商品Ａおよび商品Ｃ、ならびに、ＰＬ１１およびＰＬ１３に積み付けられている在庫商品の格納期間の長さが３日から７日までの範囲内であることを示している。 The mixed loading candidate product / inventory PL division list 33 includes a division 113a, a storage period width 113b, a mixed loading candidate product (product name) 33a, and a stock PL 33b. In the example of FIG. 20, the storage period width 113b corresponding to the value “2” of the category 113a is “3-7 days”, and “A”, “C” are the stock PL 33b as the mixed candidate product 33a of this category. “PL11” and “PL13” are registered. This means that the storage period of the products A and C extracted from the received products as mixed loading candidates and the stock products stacked on the PL11 and PL13 is within the range of 3 to 7 days. Is shown.
　図２１は、本発明の実施例２の混載積付・格納指示装置１０が出力する詰込み格納推奨リスト２９の例を示す説明図である。 FIG. 21 is an explanatory diagram showing an example of the recommended clogging storage list 29 output by the mixed loading / storage instruction device 10 according to the second embodiment of the present invention.
　詰込み格納推奨リスト２９は、混載候補商品名１８１、ロット名１７２、入荷予定日時１７３、推奨格納物量２９１、予想格納期間２２、推奨ロケ２９２、推奨ロケの商品名２９３、推奨ロケの商品物量２９４および推奨ロケの商品の予想格納期間２９５を含む。ここで、推奨格納物量２９１は、推奨ロケに格納することが推奨される混載候補商品の物量である。推奨ロケ２９２は、混載候補商品を詰込み格納することが推奨されるロケである。推奨ロケの商品名２９３および推奨ロケの商品物量２９４は、それぞれ、推奨ロケに現在格納されている商品を識別する商品名およびその商品の現在格納されている物量である。推奨ロケの商品の予想格納期間２９５は、推奨ロケに現在格納されている商品が全て消費されるまでに要すると予想される期間であり、当該推奨ロケのＰＬについて式（５）によって計算された在庫ＰＬの格納期間２２ｂに相当する。 The recommended storage list 29 includes a mixed candidate product name 181, a lot name 172, a scheduled arrival date and time 173, a recommended storage amount 291, an expected storage period 22, a recommended location 292, a recommended location product name 293, and a recommended location product amount 294. And an expected storage period 295 of the recommended location product. Here, the recommended stored amount 291 is the amount of the mixed candidate product recommended to be stored in the recommended location. The recommended location 292 is a location where it is recommended to pack and store the mixed candidate products. The product name 293 of the recommended location and the product quantity 294 of the recommended location are respectively a product name for identifying the product currently stored in the recommended location and the currently stored quantity of the product. The expected storage period 295 of the product in the recommended location is an estimated time required until all the products currently stored in the recommended location are consumed, and the PL of the recommended location is calculated by the equation (5). This corresponds to the storage period 22b of the inventory PL.
　図２１の詰込み格納推奨リスト２９の先頭のレコードの例では、新たに入荷する商品から抽出された混載候補商品Ａを、ロケ１に既に格納されている商品Ｅと混載することが推奨されている。これは、混載組合せ決定部１２５がそれらの商品の組合せを混載組合せとして決定した結果を示している。商品Ｅが格納されているロケ１が推奨ロケ２９２として出力される。 In the example of the top record in the recommended storage list 29 in FIG. 21, it is recommended that the mixed candidate product A extracted from the newly received product is mixed with the product E already stored in the location 1. Yes. This shows the result of the mixed combination determination unit 125 determining the combination of those products as a mixed combination. The location 1 in which the product E is stored is output as the recommended location 292.
　以上の方法によって、詰込み格納を行う場合においても、詰込み格納を行った結果生成された混載ＰＬの歯欠け（低充填率）ロケの発生を抑止することができ、間口の利用効率・回転率が向上する。 With the above method, even when clogging storage is performed, occurrence of chipping (low filling rate) location of mixed PL generated as a result of clogging storage can be suppressed, and frontage utilization efficiency / rotation The rate is improved.
　また、格納作業員が推奨ロケ２９２を参照することで、格納先のロケを探す手間を省くことができ、格納作業の効率化を図ることができる。また、各商品を制約条件２１４に合ったロケに格納することができるので、温度管理品や危険物を適切なエリアで保管することができ、在庫の品質（例えば冷蔵管理が必要な食料品の品質など）が向上する。 Also, by referring to the recommended location 292 for the storage worker, it is possible to save the trouble of searching for the location of the storage destination and to improve the efficiency of the storage operation. In addition, since each product can be stored in a location that meets the constraint 214, temperature-controlled products and dangerous goods can be stored in an appropriate area, and the quality of inventory (for example, food products that require refrigeration management) can be stored. Quality).
　次に、本発明の実施例３について説明する。以下に説明する相違点を除き、実施例１のシステムの各部は、図１～図１７に示された実施例１および図１８～図２１に示された実施例２の同一の符号を付された各部と同一の機能を有するため、それらの説明は省略する。 Next, Example 3 of the present invention will be described. Except for the differences described below, each part of the system of the first embodiment is given the same reference numerals as those of the first embodiment shown in FIGS. 1 to 17 and the second embodiment shown in FIGS. Since each part has the same function, the description thereof is omitted.
　実施例１では入荷段階で１ＰＬに満たない端数の入荷ＳＫＵ（１商品、１ロット）を混載させてから格納する場合について、次に実施例２では１ＰＬに満たない物量の入荷ＳＫＵを、保管エリアの在庫ＰＬに組合せてロケに詰込む場合を説明した。 In the first embodiment, when the received SKU (one product, one lot) with a fraction less than 1PL is mixed and stored at the arrival stage, in the second embodiment, the received SKU having a quantity less than 1PL is stored in the storage area. The case where it is packed in the location in combination with the stock PL of has been described.
　しかし倉庫業務では、主に保管エリアの空きロケ数の確保を目的に、１ＰＬに満たない物量の保管エリアの格納済み商品ＳＫＵ同士を組合せて、一方のＰＬに積み付けられた商品をもう一方のＰＬに移動させる場合がある。このような処理を棚寄せ処理と称する。 However, in warehousing operations, mainly for the purpose of securing the number of empty locations in the storage area, the stored products SKU in the storage area with a quantity less than 1PL are combined, and the products stacked in one PL It may be moved to PL. Such a process is referred to as a shelving process.
　この場合も、在庫商品同士の混載組合せと考えることができ、実施例１の場合と同様に、格納期間２２の似通った商品同士を混載させることで、実施例１と同様の効果を得ることができる。 In this case as well, it can be considered as a mixed combination of stock products, and the same effect as in the first embodiment can be obtained by mixing similar products with similar storage periods 22 as in the first embodiment. it can.
　すなわち、実施例３では、実施例１のように計算された混載対象物量１８３が示す数量の混載候補商品１８１（ステップＳ４）のかわりに、格納可能な数量に満たない数量の商品が格納されているロケ（より詳細には、積み付け可能な数量に満たない数量の商品が積み付けられたＰＬが置かれているロケ）に格納されている商品が、他の品目の商品と混載して保管エリア１０１に格納するか否かを決定する対象となる。 That is, in the third embodiment, instead of the mixed loading candidate product 181 (step S4) of the quantity indicated by the mixed loading target amount 183 calculated as in the first embodiment, a product having a quantity less than the storable quantity is stored. The product stored in the location (more specifically, the location where the PL with the quantity less than the quantity that can be loaded is placed) is stored together with the goods of other items It is a target for determining whether to store in the area 101.
　本実施例の混載積付・格納指示装置１０が実行する処理は、以下に説明する変更点を除いて、図５および図１６に示す通りである。 The processing executed by the mixed loading / storage instruction device 10 of the present embodiment is as shown in FIGS. 5 and 16 except for the changes described below.

Step S10 (FIG. 5): The output unit 14 outputs the shelf alignment instruction list 39. When the output is completed, the process returns to step S2 and waits for the input of the user instruction again. Here, if the shelving instruction list 39 is output in a format that can be read by a machine such as an automatic transfer robot, the shelving work can be mechanized and automated, and the efficiency of the shelving work in the warehouse can be improved.
　以降、実施例３のステップＳ９の詳細な処理を説明する。 Hereinafter, detailed processing in step S9 of the third embodiment will be described.

　ステップＳ９３（図１６）：混載組合せ決定部１２５は、在庫ＰＬ区分けリスト３４で同一区分に区分けられた在庫ＰＬ３４ａに対して、ＰＬ上の商品１１１ｂの商品属性２１４ａを参照して、制約条件１１４の混載可能１１４ｃの列がＴｒｕｅに指定されている組合せに限定して、２つの在庫ＰＬ上の商品２３ａのＰＬ換算在庫数１１１eの総和が１ＰＬ以下になる範囲で、在庫ＰＬ同士の混載組合せを生成する。[Correction 04.08.2017 based on Rule 91]
Step S93 (FIG. 16): The mixed loading combination determination unit 125 refers to the product attribute 214a of the product 111b on the PL with respect to the stock PL 34a sorted into the same category in the stock PL classification list 34, and sets the constraint condition 114. Limiting the combination of the columns that can be mixed 114c to True, the combination of the stock PLs is generated within the range where the total of the PL conversion stock numbers 111e of the products 23a on the two stock PLs is 1PL or less. To do.
　ここで、実施例１、２と同様に、１ＰＬに積付けるＳＫＵ数に制限を設けて、その範囲内でＰＬに商品を積み付けるように商品の組合せを決定しても良い。それによって、棚寄せ作業時の運搬・格納時の安全確保および出荷作業時の誤ピックのリスク低下が図れる。 Here, similarly to the first and second embodiments, the number of SKUs to be loaded on 1PL may be limited, and the combination of products may be determined so that the products are loaded on the PL within the range. As a result, it is possible to ensure safety during transportation and storage during shelving operations and to reduce the risk of erroneous picking during shipping operations.

　在庫ＰＬ区分けリスト３４では、区分１１３ａごとに格納期間幅１１３ｂとその格納期間幅に収まる在庫ＰＬ３４ａが列挙される。 In the inventory PL classification list 34, the storage period width 113b and the inventory PL 34a that falls within the storage period width are listed for each section 113a.
　図２３は、本発明の実施例３の混載積付・格納指示装置１０が出力する棚寄せ指示リスト３９の例を示す説明図である。 FIG. 23 is an explanatory diagram showing an example of the shelf loading instruction list 39 output by the mixed loading / storage instruction apparatus 10 according to the third embodiment of the present invention.
　棚寄せ指示リスト３９は、棚寄せ候補ＰＬ名３９１、現格納ロケ３９２、推奨棚寄せ物量３９３、予想格納期間２２、棚寄せ先ロケ３９４、棚寄せ先ＰＬ名３９５、棚寄せ先ロケの商品物量３９６および棚寄せ先ロケの商品の予想格納期間３９７から構成される。 The shelf alignment instruction list 39 includes a shelf alignment candidate PL name 391, a current storage location 392, a recommended shelf alignment amount 393, an expected storage period 22, a shelf alignment location 394, a shelf alignment location PL name 395, and a product amount of the shelf alignment location. 396 and the expected storage period 397 of the product at the shelf location.
　棚寄せ候補ＰＬ名３９１は、棚寄せを行う対象の候補のＰＬを識別するＰＬ名である。現格納ロケ３９２は、当該ＰＬが現在格納されているロケを示す。推奨棚寄せ物量３９３は、当該ＰＬに現在積み付けられている商品の物量（すなわち棚寄せを行うとしたら別のＰＬに移動させることになる商品の物量）である。棚寄せ先ロケ３９４および棚寄せ先ＰＬ名３９５は、それぞれ、棚寄せ先（すなわち当該棚寄せ候補のＰＬに積み付けられている商品の移動先）のロケおよびそこに置かれているＰＬを示す。棚寄せ先ロケの商品物量３９６は、棚寄せ先ロケに現在格納されている商品の物量を示す。棚寄せ先ロケの商品の予想格納期間３９７は、棚寄せ先ロケに現在格納されている商品が全て消費されるまでに要すると予想される期間であり、当該棚寄せ先ロケのＰＬについて式（５）によって計算された在庫ＰＬの格納期間２２ｂに相当する。 The shelving candidate PL name 391 is a PL name that identifies a candidate PL to be shelved. The current storage location 392 indicates a location where the PL is currently stored. The recommended shelf amount 393 is the amount of products currently stacked on the PL (that is, the amount of products to be moved to another PL if shelves are placed). The shelving destination location 394 and the shelving destination PL name 395 respectively indicate the location of the shelving destination (that is, the movement destination of the product loaded in the PL of the shelf sorting candidate) and the PL placed there. . The merchandise item quantity 396 of the shelf destination location indicates the quantity of the product currently stored in the shelf destination location. The expected storage period 397 for the product in the shelf location is an estimated period that is required until all the products currently stored in the shelf location are consumed. This corresponds to the stock PL storage period 22b calculated by 5).
　図２３の例では、ＰＬ１１の在庫をＰＬ１３に移動（棚寄せ）し、ＰＬ１２の在庫をＰＬ１４に移動（棚寄せ）する混載組合せの例を示している。これは、混載組合せ決定部１２５が、ロケ５のＰＬ１１に積み付けられている商品と、ロケ１のＰＬ１３に積み付けられている商品との組合せを混載組合せとして決定し、さらに、ロケ６のＰＬ１２に積み付けられている商品と、ロケ２のＰＬ１４に積み付けられている商品との組合せを混載組合せとして決定したことを示している。ここで、ステップＳ９２、Ｓ９３において生成した在庫ＰＬ同士の混載組合せにおいて、どちらの在庫ＰＬ３４ａが棚寄せ候補ＰＬ３９１または棚寄せ先ＰＬ３９５となるかの決定方法はいくつか考えられる。例えば、在庫ＰＬ３４ａ上のＰＬ換算在庫数１１１ｅまたは混載ＳＫＵ数が少ない在庫ＰＬ３４ａを棚寄せ候補ＰＬ３９１、多い在庫ＰＬを棚寄せ先ＰＬ３９５とすることが考えられる。または、実施例２の制約条件２１４を入力として追加して、在庫ＰＬ上の商品の商品属性２１４ａと格納先ロケのロケ属性２１４ｂの組合せを評価し、制約条件２１４で格納可能２１４ｃがＦＡＬＳＥのほうの在庫ＰＬ３４ａを棚寄せ候補ＰＬ３９１とし、他方を棚寄せ先ＰＬ３９５とすることが考えられる。混載積付・格納指示装置１０が商品の移動元（すなわち現在格納ロケ３９２）と移動先（すなわち棚寄せ先ロケ３９４）を出力し、作業員がそれを参照することによって、作業員の棚寄せ作業が効率化される。 23 shows an example of a mixed combination in which the stock of PL11 is moved (shelf-aligned) to PL13 and the stock of PL12 is moved (shelf-aligned) to PL14. This is because the mixed combination determining unit 125 determines the combination of the product stacked in the PL 11 of the location 5 and the product stacked in the PL 13 of the location 1 as the mixed combination, and further, the PL 12 of the location 6 It is shown that the combination of the product stacked in 1 and the product stacked in the PL 14 of the location 2 is determined as a mixed combination. Here, in the mixed combination of the stocks PL generated in steps S92 and S93, there are several methods for determining which stock PL34a is the shelf placement candidate PL391 or the shelf placement destination PL395. For example, it is conceivable that the PL-converted inventory number 111e on the inventory PL34a or the inventory PL34a with a small number of mixed SKUs is set as the shelf alignment candidate PL391, and the inventory PL34a with a large number of inventory PLs is set as the shelf alignment destination PL395. Alternatively, the constraint condition 214 of the second embodiment is added as an input to evaluate the combination of the product attribute 214a of the product on the inventory PL and the location attribute 214b of the storage location, and the storage condition 214c is FALSE. It is conceivable that the stock PL34a is the shelf alignment candidate PL391 and the other is the shelf alignment destination PL395. The mixed loading / storage instruction device 10 outputs the movement source (that is, the current storage location 392) and the movement destination (that is, the shelf location location 394) of the product, and the worker refers to it, so that the worker's shelf alignment is performed. Work is streamlined.
　以上の方法によって、棚寄せ作業を行う場合においても、棚寄せの結果生成された混載ＰＬの歯欠け（低充填率）ロケの発生を抑止することができ、間口の利用効率・回転率が向上する。 With the above method, even when performing shelving work, it is possible to suppress the occurrence of missing teeth (low filling rate) location in the mixed PL generated as a result of shelving, improving the efficiency and rotation rate of the frontage To do.
　以上、本発明の実施形態について述べたが、本発明はこれらの実施形態に限定されるものではない。例えば各実施例では、ＰＬに商品を積み付けてから格納する倉庫を想定したが、必ずしもＰＬに積み付ける必要は無い。例えば、ＰＬではなくＣＳ（ケース）やコンテナ単位で保管を行う棚に対して、それらの棚の１ロケーションに複数ＳＫＵを混載させる必要がある場合に、実施例１から実施例３を在庫データ１１１および入荷予定リスト１７の１ＳＫＵ単位で実施すれば、本明細書で説明した同様の効果を得ることができる。 As mentioned above, although embodiment of this invention was described, this invention is not limited to these embodiment. For example, in each embodiment, a warehouse is assumed in which products are stored after being stacked on the PL, but it is not always necessary to stack on the PL. For example, when it is necessary to load a plurality of SKUs in one location of the shelves that are stored in units of CS (cases) or containers instead of the PL, the inventory data 111 is used in the first to third embodiments. If implemented in units of 1 SKU in the arrival schedule list 17, the same effect as described in this specification can be obtained.
　また、物流倉庫に限らず、例えば生産現場でも、同一の部品棚に複数の部品を混載させて保管することが求められる。本発明を生産現場に適用すれば、格納期間が同一の部品を配置できることになり、歯欠け（低充填率）の部品棚の発生を抑止することで部品棚の利用効率向上が可能である。すなわち、本発明は、物流倉庫における商品に限らず、任意の種類の物品を対象として適用することができる。 In addition, not only in distribution warehouses but also in production sites, it is required to store a plurality of parts in the same parts shelf. If the present invention is applied to a production site, parts having the same storage period can be arranged, and the use efficiency of the parts shelf can be improved by suppressing the occurrence of a part shelf having a missing tooth (low filling rate). In other words, the present invention can be applied not only to products in a distribution warehouse but also to any type of goods.
　なお、本発明は上記した実施例に限定されるものではなく、様々な変形例が含まれる。例えば、上記した実施例は本発明のより良い理解のために詳細に説明したのであり、必ずしも説明の全ての構成を備えるものに限定されるものではない。また、ある実施例の構成の一部を他の実施例の構成に置き換えることが可能であり、また、ある実施例の構成に他の実施例の構成を加えることが可能である。また、各実施例の構成の一部について、他の構成の追加・削除・置換をすることが可能である。 In addition, this invention is not limited to the above-mentioned Example, Various modifications are included.

Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Further, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.
