Description

本発明は、通信販売業者など、異なる多数の荷主から受注した多様な出荷オーダに応じて、倉庫等の配送センタで行う在庫商品のピッキング作業の効率化を図るのに好適なピッキング作業管理システムに関する。 The present invention relates to a picking work management system suitable for improving the efficiency of picking work of inventory products performed at a distribution center such as a warehouse in accordance with various shipment orders received from a large number of different shippers such as mail order dealers. .

通販業などでは、配送設備の整った大規模な倉庫など、運送会社等の配送センタに、各種の顧客からのオーダ（注文）に備えて、多種多様な商品の在庫を大量に蓄えている。そのように配送センタに商品の在庫を大量に蓄えておけば、個人を含む多数の注文者からの多種多様な出荷オーダにも迅速に対応することができる。そこで、商品の在庫を抱えた在庫型の配送センタでは、通販業者等の荷主から出荷オーダを受け取ると、出荷オーダに対応した商品を広大な倉庫内から集め（当該作業をピッキングという。）、集めた商品を届け先毎に包装・梱包して出荷している。従って、配送センタでは、一連の出荷作業の中でも、特に商品のピッキング作業を作業員によって如何に効率よく行うかが、作業管理上、最も重要な要素になっている。 In the mail order business and the like, a large number of stocks of various products are stored in order to receive orders (orders) from various customers in a distribution center such as a shipping company such as a large-scale warehouse equipped with delivery facilities. If a large amount of merchandise is stored in the distribution center in this way, it is possible to respond quickly to a wide variety of shipping orders from a large number of orderers including individuals. Therefore, in an inventory-type distribution center that has a stock of goods, when receiving a shipping order from a shipper such as a mail order dealer, the goods corresponding to the shipping order are collected from a vast warehouse (this operation is called picking) and collected. The products are packaged and packed for each delivery destination. Therefore, in the distribution center, the most important element in work management is how efficiently the picking work of the product is performed by the worker among a series of shipping work.

そこで、一般には、ピッキング作業の効率を考えて、オーダ単位（届け先単位）に商品をピッキングして一つの出荷単位にまとめるオーダピッキング方式か、或いは、オーダに関係なく、商品の種類単位で集計し、商品種ごとにそれぞれ一括してピッキングし、それらを後工程でオーダに応じて届け先毎に仕分けするトータルピッキング方式が採られ、この２種類のピッキング方式のいずれかを単純に選んで作業されている。 Therefore, in general, considering the efficiency of picking work, the order picking method that picks up products in order units (destination units) and collects them into one shipping unit, or counts by product type regardless of order. A total picking method is adopted in which picking is performed for each product type in a lump, and sorting is performed for each delivery destination according to the order in the subsequent process, and either of these two types of picking methods is simply selected and operated. Yes.

しかし、オーダピッキング方式は、比較的オーダ商品が多品種少数の出荷作業に主眼がおかれ、一方で、トータルピッキング方式は、比較的オーダ商品が少品種多数の出荷作業に主眼が置かれているため、いずれか一方の方式のみにより作業をしようとすると、多種多様な出荷オーダの特性に柔軟に対応しきれず、ピッキング作業の効率があまり上がらないという問題があった。 However, the order picking method focuses on the shipping work for a relatively small number of products with a large number of products, while the total picking method focuses on the shipping work for a relatively small number of products with a small number of products. Therefore, when trying to work by only one of the methods, there is a problem that the efficiency of the picking work is not so much improved because the characteristics of various shipment orders cannot be flexibly handled.

そこで、従来のピッキング作業管理システムの中には（特許文献１参照）、オーダピッキング時間と、トータルピッキング時間および二次仕分け時間の合算時間とを、作業判定部で比較し、所用時間がより短時間であると判定されたのがオーダピッキングの作業であると、オーダ群を構成する出荷オーダ毎にオーダ数に応じた商品のピッキング作業を行うオーダピッキングリストを生成して出力する一方、所用時間がより短時間であると判定されたのがトータルピッキングおよび二次仕分けの作業であると、出荷オーダ群より特定した、同一オーダ商品の合算値が予め定めた閾値以上になる商品の、前記合算値に応じたピッキング作業を行うトータルピッキングリストを生成して出力し、それぞれピッキングリストを作業員に指示作業として示し、オーダ特性に応じてピッキング作業の効率化を図ろうとするシステムが提案されている。
特開２００５−２０６２８１号公報 Therefore, in the conventional picking work management system (see Patent Document 1), the order picking time is compared with the total time of the total picking time and the secondary sorting time in the work determination unit, and the required time is shorter. If it is determined that the time is the order picking work, an order picking list for picking up products according to the number of orders is generated and output for each shipment order that constitutes the order group. When the total picking and secondary sorting operations are determined to be shorter, the sum of products that are specified from the shipping order group and whose sum value of the same order product is equal to or greater than a predetermined threshold Generate and output a total picking list that performs picking work according to the value, and each picking list is used as an instruction work to the worker And, there has been proposed a system to attempt is made to streamline the picking operation in accordance with the order characteristics.
JP-A-2005-206281

従来のピッキング作業管理システムでは、オーダピッキングとトータルピッキングという限られた作業方式の中から、作業の所用時間の算定に基づいて、いずれか一方が二者択一的に選択されるシステムになっている。ところが、一般に、配送センタでは、荷主が多様な商品を取り扱い、しかも注文客に多くの個人を抱える通販業者のような場合に、受注する出荷オーダが、その多種多様性から、オーダピッキング方式又はトータルピッキング方式による作業に馴染む多品種少数の場合や少品種多数の場合に限らず、多品種多数の場合もあれば、少品種少数の場合もあり、他方で、オーダが出荷頻度の多い特定種類の商品で完結する場合も混在しているのが実情である。従って、作業方式がオーダピッキングかトータルピッキングかの二者択一である従来のピッキング作業管理システムによっては、ここまで多種多様な出荷オーダの特性に対して、柔軟に適応することができない。しかも、あくまで作業時間のみを基準にピッキング作業方式を決定するのでは、オーダ特性によっては、作業時間は短いが作業員の人数がより多く必要になる非効率的な作業方式が選択されることがあるという問題もあり、結局は、ピッキング作業の効率を十分には向上させることができないという課題があった。 In the conventional picking work management system, either one of the limited work methods of order picking and total picking is selected based on the calculation of the required work time. Yes. However, in general, in a distribution center, when a shipper handles a variety of products and the ordering customer has a large number of individuals, a shipping order to be ordered is ordered picking or totaling due to its wide variety. It is not limited to the case of a small number of multiple varieties or a large number of small varieties that are compatible with the picking method, but there may be a large number of many varieties or a small number of small varieties. The actual situation is that there are cases where products are completed. Therefore, a conventional picking work management system in which the work method is an alternative of order picking or total picking cannot flexibly adapt to the characteristics of various shipping orders so far. In addition, if the picking work method is determined based only on the work time, an inefficient work method that requires less work time but requires more workers may be selected depending on the order characteristics. In the end, there was a problem that the efficiency of picking work could not be improved sufficiently.

そこで、本発明の目的は、多種多様な出荷オーダの特性に適応する最適なピッキング作業方式を選択し、配送センタでのピッキング作業の効率を飛躍的に向上させるピッキング作業管理システムを提供することにある。 SUMMARY OF THE INVENTION An object of the present invention is to provide a picking work management system that selects an optimum picking work method that adapts to the characteristics of a wide variety of shipping orders and dramatically improves the efficiency of picking work at a distribution center. is there.

Are connected to client terminals such as a product management terminal 6, a product inspection management terminal 7, and a product return management terminal 8. The work management server 4 is connected to a communication terminal 9 such as a mobile phone or a personal computer owned by a part-time worker at a transport company via the Web server 10 via the network.

配送センタＳは、荷主から、出荷オーダを一括集中的に受け付ける運送会社の受注窓口で、配送設備の整った倉庫などの施設である。配送センタＳの基本管理サーバ１は、キーボード・マウス等のポインティングデバイスから成る入力装置１１、入力データのモニタに用いる表示装置１２、各種データを出力する出力装置１３、本システムが有する機能を実現させるプログラム１４を格納したメモリ１５、各種データベース・マスタ・ファイルを格納した記憶装置１６を、システム全体を統括的に制御処理する制御装置１７に接続してなる。 The delivery center S is an order window of a shipping company that receives shipment orders from a shipper in a centralized manner, and is a facility such as a warehouse equipped with delivery facilities. The basic management server 1 of the distribution center S realizes an input device 11 composed of a pointing device such as a keyboard / mouse, a display device 12 used for monitoring input data, an output device 13 for outputting various data, and the functions of this system. A memory 15 storing a program 14 and a storage device 16 storing various database master files are connected to a control device 17 that performs overall control processing of the entire system.

記憶装置１６は、商品別在庫データベース２０、ロケーション別在庫データベース２１、出荷商品データベース２２、出荷管理データベース２３、作業効率データベース２４等のデータベースの他に、ピッキング判定条件マスタ２５、商品マスタ２６等の各種マスタを備える。 The storage device 16 includes various products such as a picking determination condition master 25 and a product master 26 in addition to databases such as a stock database 20 by product, a stock database 21 by location, a shipped product database 22, a shipment management database 23, and a work efficiency database 24. Provide a master.

商品別在庫データベース２０は、入庫処理端末５から取り込まれる入庫商品単位に、商品番号で関連付けて商品名や個数を含む商品在庫データを格納している。ロケーション別在庫データベース２１は、入庫商品の在庫位置を示すロケーションを、商品毎に商品番号で関連付けて商品名や個数と共に在庫位置データとして格納している。出荷商品データベース２２は、荷主端末２…から出荷オーダ情報を受信すると、それら出荷オーダ情報を取り込んで、出荷番号で関連付けて商品毎に商品番号・商品名・個数・種類・届け先を含む出荷データとして格納する。出荷データは、Ａ・Ｂ・Ｃ各社等の荷主単位に分けて随時蓄積する。出荷管理データベース２３は、出荷商品データベース２２に取り込んだ出荷データにピッキング選別結果を、ピッキング判定条件を付加して格納する。作業効率データベース２４には、過去に選定された各ピッキング方式のピッキングリスト単位に計時した作業時間等を格納している。 The product-by-product inventory database 20 stores product stock data including the product name and quantity in association with the product number received from the warehousing processing terminal 5 by the product number. The location-specific inventory database 21 stores the location indicating the inventory position of the received product as an inventory location data together with the product name and number in association with the product number for each product. When the shipping merchandise database 22 receives the shipping order information from the shipper terminal 2..., The shipping merchandise database 22 takes in the shipping order information and associates it with the shipping number as shipping data including the product number, the product name, the number, the type, and the delivery destination for each product. Store. Shipment data is divided into units of shippers such as A, B, and C companies and accumulated as needed. The shipping management database 23 stores the picking selection result in the shipping data fetched into the shipping merchandise database 22 with picking determination conditions added. The work efficiency database 24 stores the work time and the like counted in the picking list unit of each picking method selected in the past.

ピッキング判定条件マスタ２５は、ピッキング選定部３１で演算するときなどに使用する基準値などの各種判定条件が格納されている。商品マスタ２６は、商品別明細、即ち商品単位に商品名、商品番号、荷扱い上の注意事項等を格納している。 The picking determination condition master 25 stores various determination conditions such as a reference value used when calculating by the picking selection unit 31. The merchandise master 26 stores product details, that is, merchandise name, merchandise number, handling precautions, etc. for each merchandise.

一方、基本管理サーバ１は、プログラム１４として、出荷商品引当部３０、ピッキング選定部３１、ピッキングリスト生成部３２、作業予定者抽出部３３および作業予定者特定部３４等を備える。出荷商品引当部３０は、出荷商品データベース２２から対象日の出荷データを読み出し、その出荷データに基づき商品番号単位で商品の出荷合計個数を算出する一方、商品別在庫データベース２０から商品在庫データを読み出し、その商品在庫データに商品番号別の商品の出荷合計個数を照合し、対象日に出荷オーダに対応する在庫があるか否かを引当処理するようにプログラムされている。 On the other hand, the basic management server 1 includes, as the program 14, a shipping merchandise allocation unit 30, a picking selection unit 31, a picking list generation unit 32, a planned work person extracting unit 33, a planned work person specifying unit 34, and the like. The shipping merchandise allocation unit 30 reads the shipping data of the target date from the shipping merchandise database 22 and calculates the total shipment number of merchandise in units of merchandise numbers based on the shipping data, while reading the merchandise inventory data from the inventory database 20 for each merchandise. The program is programmed so as to check whether or not there is a stock corresponding to the shipment order on the target date by comparing the total number of products shipped by product number with the product inventory data.

ピッキング選定部３１は、出荷商品データベース２２から対象日の出荷データを読み出し、出荷データに基づいて対象日に出荷予定の商品種類数と出荷オーダ数を集計する。そして、商品種類数が第１基準値以上か否かを演算し、次いで、いずれの演算結果であっても、出荷オーダ数が第２基準値以上か否かを演算し、その演算結果が第２基準値以上のときは、更に特定種類数で出荷が完結する出荷オーダ数が第３基準値以上か否かを演算することにより最適なピッキング方式を選定するようにプログラムされている。そのため、ピッキング判定条件マスタ２５には、ピッキング選定時に読み出して使用する、商品種類数の第１基準値（例えば1,500種類）と、出荷オーダ数の第２基準値（例えば5,000件）と、特定種類数で出荷が完結する出荷オーダ数の第３基準値（例えば100件）及びそのときの商品の特定種類数（例えば50種類）が記録されている。 The picking selection unit 31 reads the shipment data of the target date from the shipment product database 22, and counts the number of product types scheduled to be shipped and the number of shipment orders based on the shipment data. Then, it is calculated whether or not the number of product types is greater than or equal to the first reference value, and then, for any calculation result, whether or not the number of shipment orders is greater than or equal to the second reference value is calculated. When the value is 2 or more, the program is programmed to select the optimum picking method by calculating whether or not the number of shipment orders for which the shipment is completed with a specific number of items is greater than or equal to the third reference value. Therefore, the picking determination condition master 25 includes a first reference value (for example, 1,500 types) for the number of product types, a second reference value (for example, 5,000 items) for the number of shipment orders, and a specific type to be read and used when picking is selected. The third reference value (for example, 100 cases) of the number of shipping orders for which the shipment is completed by the number and the specific number of types (for example, 50 types) of products at that time are recorded.

そこで、ピッキング選定部３１は、商品種類数が第１基準値（例えば1,500種類）以下で且つ出荷オーダ数が第２基準値（例えば5,000件）以下の演算結果のときは（図２参照）、届け先別に仕切って出荷商品３５を入れる仕切り部３６を有した特殊台車Ｃ１を、指定ロケーション順に移動しながら出荷商品３５を指定個数取り出して届け先別に仕切り部３６内に入れて集める第１ピッキング方式（例えばカートピッキングとも云う。）を選定する。 Therefore, when the number of product types is a first reference value (for example, 1,500 types) or less and the number of shipment orders is a second reference value (for example, 5,000) or less (see FIG. 2), A first picking system (for example, a special cart C1 having a partition part 36 for separating shipments 35 by delivery destination and taking out a designated number of shipment products 35 while moving in the designated location order and collecting them in the partition part 36 for each delivery destination (for example, Also called cart picking.)

商品種類数が第１基準値以上で且つ出荷オーダ数が第２基準値以下の演算結果のときは（図３・図４参照）、配送センタＳ内でピッキングエリア（ａ）〜（ｆ）を複数に区分けして配置する一方、商品をソーティング順に並べて載せるプット（置き場所）３９を設けた商品棚４０を多段に備えた特殊台車Ｃ２を、ピッキングエリア別に指定ロケーションに沿って移動しながら出荷商品を１個ずつ取り出して商品棚４０のプット３９上に載せて集めてから、中央のソートエリア（ｇ）で届け先別に仕分けする第２ピッキング方式（例えばピースピッキングとも云う。）を選定する。 When the number of product types is the first reference value or more and the calculation result is less than the second reference value (see FIGS. 3 and 4), the picking areas (a) to (f) are set in the distribution center S. Products shipped while moving along a designated location for each picking area with a special cart C2 equipped with multiple shelves 40 with a put (place) 39 on which products are arranged in the order of sorting and placed in order. Are picked up one by one and collected on the put 39 of the product shelf 40, and then the second picking method (for example, also referred to as piece picking) is selected for sorting by destination in the central sort area (g).

商品種類数が第１基準値以下である一方、出荷オーダ数が第２基準値以上で且つ特定種類数（例えば50種類）で出荷が完結する出荷オーダ数が第３基準値（例えば100件）以上の演算結果のときは（図６参照）、第１ピッキング方式と、作業員の周りに商品棚４５を配置し、それら商品棚４５に出荷頻度の多い特定種類の商品を配列した所定の作業場所で、台車移動することなく、そのまま商品棚４５から出荷商品を取り出して届け先毎に集約する第３ピッキング方式（例えばブースピッキングとも云う。）とを組み合わせた、第４ピッキング方式を選定する。 While the number of product types is less than or equal to the first reference value, the number of shipment orders whose shipment order number is greater than or equal to the second reference value and is completed with a specific number of types (for example, 50 types) is the third reference value (for example, 100 cases) In the case of the above calculation results (see FIG. 6), the first picking method and a predetermined work in which product shelves 45 are arranged around workers and specific types of products frequently shipped are arranged on the product shelves 45. The fourth picking method is selected in combination with the third picking method (for example, also referred to as booth picking) in which a shipped product is taken out from the product shelf 45 as it is and is collected for each delivery destination without moving the carriage at the place.

商品種類数が第１基準値以上で、出荷オーダ数も第２基準値以上で且つ特定種類数で出荷が完結する出荷オーダ数が第３基準値以上の演算結果のときは、第２ピッキング方式と第３ピッキング方式とを組み合わせた、第５ピッキング方式を選定するようにプログラムされている。 When the number of product types is equal to or greater than the first reference value, the number of shipment orders is equal to or greater than the second reference value, and the shipment order number that completes shipment with the specific number of types is the calculation result equal to or greater than the third reference value, the second picking method Is programmed to select the fifth picking method in combination with the third picking method.

ピッキングリスト生成部３２は、出荷商品データベース２２から出荷番号をキーに出荷データを読み出すと共に、ロケーション別在庫データベース２１から商品番号をキーに在庫位置データを読み出し、最適と選定されたピッキング方式に合わせて出荷データおよび在庫位置データを記録してピッキングリストを生成するようにプログラムされている。ピッキングリスト生成部３２で生成されるピッキングリストは、第１のカートピッキング方式に関するものか、第２のピースピッキング方式に関するものか、第３のブースピッキング方式に関するものかで異なり、それは出荷管理データベース２３に格納される。 The picking list generating unit 32 reads out the shipping data from the shipping product database 22 using the shipping number as a key, and also reads out the inventory position data from the location-specific stock database 21 using the product number as a key, in accordance with the picking method selected as optimal. Programmed to record shipping data and inventory location data to generate a picking list. The picking list generated by the picking list generating unit 32 is different depending on whether it is related to the first cart picking method, the second piece picking method, or the third booth picking method. Stored in

第１のカートピッキングリスト５０は、図２に示すように、在庫位置（ロケーション）、商品番号（商品コード）、商品種類（商品区分）、個数（総出荷数量）、届け先等のピッキング情報を関連付けて記録される。従って、作業員は、第１のカートピッキングリスト５０を確認し、例えば特殊台車Ｃ１を移動して3A-01-002-02へ向かい、該ロケーションから、商品番号999433-1の化粧品を8個取り出し、届け先（A02,A09,A10,A11,A12,A19,A21,A22）別に１個ずつ仕切り部３６内に入れて集める。すべてのロケーションを回ると、48届け先への出荷指示（オーダ）のピッキングを完了する。 As shown in FIG. 2, the first cart picking list 50 associates picking information such as inventory position (location), product number (product code), product type (product category), quantity (total shipment quantity), and delivery destination. Recorded. Therefore, the worker confirms the first cart picking list 50 and moves, for example, the special cart C1 to 3A-01-002-02, and takes out eight cosmetics having the product number 994333-1 from the location. , One by one in the partition 36 for each destination (A02, A09, A10, A11, A12, A19, A21, A22). After going through all locations, the picking of shipping instructions (orders) to 48 destinations is completed.

第２のピースピッキングリスト６０は、図５に示すように、ピッキング対象商品の１個ずつと対応するピッキングラベル５１・５２…を作成して１枚のピッキングシート上に剥離自在に貼り付けて形成してなる。ピッキングラベル５１・５２…には、それぞれ商品名や商品番号５４の他に、ロケーション番号５５、棚番号５６、届け先番号５７等のピッキング情報を関連付けて記録される。棚番号５６には、特殊台車Ｃ２のカート番号５６ａや、プット部３９を識別するプット番号５６ｂを含む。一方、特殊台車Ｃ２の商品棚４０上の各プット部３９には、届け先順にプット番号５６ｂが割り付けられている。従って、作業員は、ピッキングリスト６０をぶら下げて特殊台車Ｃ２を移動し、担当するピッキングエリアへ赴いてから、例えばピッキングラベル５１を確認し、ロケーション2A-1-14-24へ向かって、ピッキングラベル５１を剥がす一方、ロケーション2A-1-14-24から商品番号767022311-7のキャミソールを取り出してピッキングラベル５１を貼り付け、商品棚４０にあって該当するプット番号（15）のプット部３９の上に置く。それから、ピッキング対象商品のすべて（例えば最大72個）をピッキングして後、中央のソートエリア（ｇ）へ移動して届け先別に仕分けする。そのとき、プット番号が若い順に商品を商品棚４０から取り出して届け先別に仕分けする（種蒔きする）。図示例では、プット番号が15番のプット部３９から商品番号767022311-7のキャミソールを取り出して届け先番号がF11-1の仕分け箱５９ａに投入して仕分けする。仕分け箱５９ａは、１２個口で１つのソート間口５９を構成する。そして、特殊台車Ｃ２の商品のプット番号を、ソートエリア（ｇ）における届け先のソート間口５９の順序に合わせて割り付けてあり、ソートスタート位置から仕分けを開始すると、後へ戻ることなく一方通行で仕分けして完了するようになっている。 As shown in FIG. 5, the second piece picking list 60 is formed by creating picking labels 51, 52... Corresponding to each of the picking target products and pasting them on a single picking sheet so as to be peeled off. Do it. In addition to the product name and product number 54, picking information such as a location number 55, a shelf number 56, and a delivery destination number 57 is recorded in association with the picking labels 51, 52. The shelf number 56 includes a cart number 56a of the special cart C2 and a put number 56b for identifying the put unit 39. On the other hand, a put number 56b is assigned to each put part 39 on the product shelf 40 of the special cart C2 in order of delivery destination. Therefore, the worker hangs the picking list 60, moves the special cart C2, and goes to the picking area in charge, for example, confirms the picking label 51, and goes to the location 2A-1-14-24 toward the picking label. 51, while removing the camisole of the product number 767022311-7 from the location 2A-1-14-24 and pasting the picking label 51 on the shelf 40 of the corresponding put number (15) Put on. Then, after picking all of the picking target products (for example, 72 at the maximum), the picked goods are moved to the central sorting area (g) and sorted by destination. At that time, the products are taken out from the product shelf 40 in ascending order of the put numbers and sorted according to the delivery destination (seeding). In the illustrated example, the camisole with the product number 767022311-7 is taken out from the put part 39 with the put number 15 and put into the sorting box 59a with the delivery destination number F11-1 for sorting. The sorting box 59a forms one sort frontage 59 with 12 mouths. The put number of the product of the special cart C2 is assigned in accordance with the order of the sort opening 59 of the delivery destination in the sort area (g). When sorting is started from the sort start position, sorting is performed one-way without returning to the back. To complete.

第３のブースピッキングリスト７０は、図７に示すように、出荷番号６５、ソート番号（届け先番号）６６、総Pcs数（個数）６７、商品棚番号６８等のピッキング情報を関連付けて記録される。従って、作業員は、所定の作業場所で、第３のブースピッキングリスト７０を確認し、商品棚番号６８を元に、商品種類単位に並べて置いた商品棚４５から、該当種類の商品を取り出して届け先別に仕分け箱に入れて集約する。 As shown in FIG. 7, the third booth picking list 70 is recorded in association with picking information such as a shipping number 65, a sort number (destination number) 66, a total number of Pcs (number) 67, and a product shelf number 68. . Therefore, the worker confirms the third booth picking list 70 at a predetermined work place, and takes out the corresponding type of product from the product shelf 45 arranged in the product type unit based on the product shelf number 68. Put them in a sorting box by destination.

なお、作業予定者抽出部３３は、作業効率データベース２４から過去に選定された各ピッキング方式のピッキングリスト単位に計時した作業時間等を読み出し、出荷対象日にピッキング作業を行うに必要な作業員の人数（例えば100人）を抽出するようにプログラムされている。作業予定者特定部３４は、作業管理サーバ４に備えた労務管理データベース４１から作業員個々の各ピッキング方式による作業時間を読み出し、携帯電話等の通信端末９…から出勤予定の登録のあった作業候補者（例えば120人）の中から特定の作業員100人に絞り込んで特定するようにプログラムされている。 In addition, the scheduled work person extraction unit 33 reads the work time and the like measured in the picking list unit of each picking method selected in the past from the work efficiency database 24, and the worker's necessary for performing the picking work on the shipment target day. It is programmed to extract the number of people (for example, 100 people). The scheduled work person specifying unit 34 reads the work time by each picking method for each worker from the labor management database 41 provided in the work management server 4, and the work for which the work schedule is registered from the communication terminal 9 such as a mobile phone. It is programmed to narrow down to 100 specific workers from candidates (for example, 120).

一方、作業管理サーバ４は、記憶装置４０に、労務管理データベース４１、作業計画データベース４２、作業者マスタ４３等を備える。労務管理データベース４１には、各作業員単位のピッキング作業時間等を格納している。作業計画データベース４２は、出荷対象日のピッキング作業を行うに必要な作業員数とその特定作業員データ等を取り込んで作業計画データとして格納する。 On the other hand, the work management server 4 includes a labor management database 41, a work plan database 42, a worker master 43, and the like in the storage device 40. The labor management database 41 stores picking work time and the like for each worker. The work plan database 42 takes in the number of workers necessary for performing the picking work on the shipping date and the specific worker data, and stores them as work plan data.

さて次に、上述した構成のピッキング作業管理システムの作用について、基本管理サーバ１の処理動作を中心に、図８・図９に示す処理手順に沿って説明する。 Next, the operation of the picking work management system having the above-described configuration will be described along the processing procedure shown in FIGS. 8 and 9, focusing on the processing operation of the basic management server 1. FIG.

基本管理サーバ１は、荷主端末２…から、所定の届け先へ必要個数の特定商品を運送する出荷オーダを通信管理サーバ３を経由して受信する（Ｓ１）。出荷オーダを受信すると、出荷オーダ情報を出荷商品データベース２２に取り込んで、出荷番号で関連付けて商品毎に商品番号・商品名・個数・種類・届け先を含む出荷データとして格納する（Ｓ２）。出荷データは、Ａ・Ｂ・Ｃ各社等の荷主単位に分けて随時蓄積され、荷主別に情報処理されるが、以下は、荷主１社の情報処理について説明する。 The basic management server 1 receives from the shipper terminal 2... Via the communication management server 3 a shipping order for transporting a required number of specific commodities to a predetermined delivery destination (S1). When the shipping order is received, the shipping order information is taken into the shipping product database 22 and associated with the shipping number and stored as shipping data including the product number, the product name, the number, the type, and the delivery destination for each product (S2). The shipment data is accumulated as needed in units of shippers such as A, B, and C companies, and is processed for each shipper. Hereinafter, information processing of one shipper company will be described.

そこで、基本管理サーバ１は、まず、出荷商品引当部３０によって出荷対象日に出荷オーダ情報に対応する商品の在庫があるか否か引当処理する（Ｓ３）。その場合、出荷商品引当部３０は、出荷商品データベース２２から対象日の出荷データを読み出し、出荷データに基づき商品番号単位で商品の出荷合計個数を算出する（Ｓ３ａ）。一方、商品別在庫データベース２０から商品在庫データを読み出し、商品在庫データに商品番号別の出荷合計個数を照合し、対象日に出荷オーダに対応する在庫があるか否かを引当処理する（Ｓ３ｂ）。引当てが可能な場合、出荷商品引当部３０は、引当済みフラグを付加して出荷データを更新し、商品の明細（商品名・個数・届け先）単位で出荷商品データベース２２に格納する（Ｓ３ｃ）。引当て不可の場合は、引当不可フラグを付加して出荷データを更新して出荷商品データベース２２に格納する（Ｓ３ｄ）。こうして出荷データを確定処理する。 Therefore, the basic management server 1 first allocates whether or not there is an inventory of products corresponding to the shipping order information on the shipping target date by the shipping product allocation unit 30 (S3). In that case, the shipment merchandise allocation unit 30 reads the shipment data of the target date from the shipment merchandise database 22, and calculates the total number of merchandise shipped in merchandise number units based on the shipment data (S3a). On the other hand, product inventory data is read from the product-specific inventory database 20, the total number of shipments by product number is checked against the product inventory data, and an allocation process is performed to determine whether there is inventory corresponding to the shipment order on the target date (S3b). . If the allocation is possible, the shipping merchandise allocation unit 30 adds the allocated flag, updates the shipping data, and stores it in the shipping merchandise database 22 in units of merchandise details (product name / number / destination) (S3c). . When the allocation is impossible, the allocation data is updated by adding an allocation impossible flag and stored in the shipping product database 22 (S3d). Thus, the shipping data is finalized.

次いで、基本管理サーバ１は、引当てが可能な場合に初めて、図９に示すように、最適ピッキング方式を選定するステップへ移行する。その場合、事前にピッキング選定部３１が出荷商品データベース２２から対象日の出荷データを読み出し、その出荷データに基づいて対象日に出荷予定の商品種類数と出荷オーダ数（出荷指示件数）を集計する（Ｓ４）。それから、ピッキング選定ステップを開始する。 Next, the basic management server 1 proceeds to the step of selecting the optimum picking method as shown in FIG. 9 only when allocation is possible. In that case, the picking selection unit 31 reads the shipment data of the target date from the shipment product database 22 in advance, and totals the number of product types scheduled to be shipped on the target date and the number of shipment orders (number of shipment instructions) based on the shipment data. (S4). Then, the picking selection step is started.

そこで、ピッキング選定部３１は、まず商品種類数が第１基準値（例えば1,500種類）以上か否かを演算する（Ｓ５）。次いで、いずれの演算結果の場合であっても、出荷オーダ数が第２基準値（例えば1,500種類）以上か否かを演算する（Ｓ６ａ・Ｓ６ｂ）。そのうち、商品種類数が第１基準値以下で、且つ出荷オーダ数が第２基準値以下の演算結果のときは、第１のカートピッキング方式を選定する（Ｓ７）。 Therefore, the picking selection unit 31 first calculates whether the number of product types is equal to or greater than a first reference value (for example, 1,500 types) (S5). Next, in any calculation result, it is calculated whether or not the number of shipping orders is equal to or more than a second reference value (for example, 1,500 types) (S6a and S6b). Among them, when the number of product types is the first reference value or less and the calculation result is the number of shipping orders equal to or less than the second reference value, the first cart picking method is selected (S7).

一方、商品種類数が第１基準値以上で、出荷オーダ数が第２基準値以下の演算結果のときは、第２のピースピッキングを選定する（Ｓ８）。 On the other hand, when the product type number is equal to or greater than the first reference value and the shipment order number is equal to or less than the second reference value, the second piece picking is selected (S8).

また、ピッキング選定部３１は、出荷オーダ数が第２基準値以上か否かを演算したときに、その演算結果が第２基準値以上のときは、更に特定種類数（例えば50種類）で出荷が完結する出荷オーダ数が第３基準値（例えば100件）以上か否かを演算する（Ｓ９ａ・Ｓ９ｂ）。その演算結果が、商品種類数が第１基準値以下である一方、出荷オーダ数が第２基準値以上で且つ特定種類数で出荷が完結する出荷オーダ数が第３基準値以上のときは、第１のカートピッキング方式と第３のブースピッキング方式とを組み合わせた、第４ピッキング方式を選定する（Ｓ１０）。 Further, when the picking selection unit 31 calculates whether or not the number of shipping orders is equal to or greater than the second reference value, if the calculation result is equal to or greater than the second reference value, the picking selection unit 31 further ships with a specific number of types (for example, 50 types). It is calculated whether or not the number of shipping orders that completes is greater than or equal to a third reference value (for example, 100) (S9a, S9b). When the calculation result indicates that the number of product types is less than or equal to the first reference value, the number of shipment orders is greater than or equal to the second reference value, and the number of shipment orders that completes shipment with a specific number of types is greater than or equal to the third reference value. A fourth picking method is selected by combining the first cart picking method and the third booth picking method (S10).

更に、商品種類数が第１基準値以上で、出荷オーダ数も第２基準値以上で且つ特定種類数で出荷が完結する出荷オーダ数が第３基準値以上の演算結果のときは、第２のピースピッキング方式と第３のブースピッキング方式とを組み合わせた、第５ピッキング方式を選定する（Ｓ１１）。しかる後、以上のピッキング選別結果を、ピッキング判定条件（基準値等）を付加して出荷データと共に出荷管理データベース２３に格納してピッキング選定動作を終了する。 Further, when the number of product types is equal to or greater than the first reference value, the number of shipment orders is equal to or greater than the second reference value, and the shipment order number that completes shipment with the specific number of types is the calculation result equal to or greater than the third reference value, The fifth picking method, which combines the piece picking method and the third booth picking method, is selected (S11). Thereafter, the above picking selection result is added to the picking determination condition (reference value, etc.) and stored in the shipping management database 23 together with the shipping data, and the picking selecting operation is completed.

そこで、ピッキング方式の選定を終えると、基本管理サーバ１は、ピッキングリスト生成部３２が出荷商品データベース２２から出荷番号をキーに出荷データを読み出すと共に、ロケーション別在庫データベース２１から商品番号をキーに在庫位置データを読み出し、最適と選定されたピッキング方式に合わせて出荷データおよび在庫位置データを記録して各ピッキングリストを生成し、出力装置１３によって出力する。そして、各ピッキングリストは、ピッキング作業用の帳票として各々の仕様にプリントアウトされ、例えば100名の特定ピッキング作業員に手渡される。 Therefore, when the selection of the picking method is completed, the basic management server 1 reads the shipment data from the shipment product database 22 using the shipment number as a key, and the stock management unit 1 uses the product number as a key from the location-specific inventory database 21. The position data is read out, the shipping data and the inventory position data are recorded in accordance with the picking method selected as optimum, each picking list is generated, and output by the output device 13. Each picking list is printed out as a picking work form in each specification, and handed to, for example, 100 specific picking workers.
