Description

本発明は、生産管理システムにおける製番に対応して部材の引当を実行するための引当実行プログラム、引当実行システム、及び引当実行方法に関するものである。 The present invention relates to an allocation execution program, an allocation execution system, and an allocation execution method for executing allocation of members in accordance with product numbers in a production management system.

従来より製造業においては、部材の調達や生産工程を管理する生産管理システムが広く用いられている。生産管理システムにおいては、納期短縮や生産コスト削減の観点から、無駄のない部材の効率的な手配や管理が重要な要素となっている。 In the manufacturing industry, production management systems for managing material procurement and production processes have been widely used. In production management systems, efficient arrangement and management of lean parts is an important factor from the viewpoint of shortening delivery times and reducing production costs.

これらの機能を果たす目的で採用されている方式として、製品の製番により部材の計画管理を行う製番管理方式や、製番に関わらず在庫総量から部材をコントロールするＭＲＰ方式が知られている。 As a method employed for the purpose of fulfilling these functions, there are known a production number management method for managing the plan of a member by the product number, and an MRP method for controlling the member from the total inventory regardless of the production number. .

製番管理方式では、製品の製番ごとに部材所要量の計画を作成し、在庫情報や発注情報において当該製番で使用する部材を割当てる「引当」処理を行うことにより、部材の調達管理や製造進捗状況を管理する。ここで「引当」とは、ある製番の計画数を算出する場合に、在庫情報や発注情報として記録されている部材について、使用可能なもの（未引当）を使用予定（引当済）に変えることにより、他の製番から使用できないようにすることをいう。 In the production number management method, a procurement plan for parts is created by creating a plan for part requirements for each product production number and performing an “allocation” process that allocates the parts to be used for that production number in the inventory information and ordering information. Manage manufacturing progress. Here, “reserve” means that when calculating the planned number of a certain product number, the usable material (unallocated) is changed to the planned use (allocated) for the members recorded as inventory information and order information. This means that it cannot be used from other product numbers.

この方式においては部材を時系列的に管理することが可能であり、生産計画と部材の対応関係が把握し易いというメリットがあるものの、急な注文により生産計画が変更された場合には、製番の割当てを変更するのに手間がかかるという問題点を有している。 In this method, it is possible to manage parts in time series, and there is an advantage that it is easy to grasp the correspondence between production plans and parts, but if the production plan is changed due to a sudden order, There is a problem that it takes time to change the assignment of numbers.

ＭＲＰ方式では、特定の時点毎に部材の所要数量と在庫数量を算出して、調達が必要な数量を部材全体として管理する。上記のような生産計画の変更には比較的強いものの、時系列的な管理がされていないために、実際に部材調達の計画と実績に差が生じた場合に、生産計画にどのような影響が生じるかを把握しにくいという問題点を有している。 In the MRP method, the required quantity and inventory quantity of a member are calculated at a specific point in time, and the quantity that needs to be procured is managed as a whole member. Although it is relatively strong against changes in the production plan as described above, it is not managed in time series, so if there is a difference between the actual material procurement plan and the actual results, what kind of impact will it have on the production plan? It has a problem that it is difficult to grasp whether or not this occurs.

このように製番管理方式とＭＲＰ方式は、それぞれ異なる特徴を有しているため、現在利用されている生産管理システムにおいては、製番管理方式をベースにしながらＭＲＰ方式により製番に対する引当の見直しを行うなど、両者を併用する方法が一般的となっている。 As described above, the production number management method and the MRP method have different characteristics. Therefore, in the currently used production management system, the provision for the production number is reviewed by the MRP method while using the production number management method as a base. For example, a method using both of them is generally used.

尚、本願発明に関連する技術として、以下の特許文献にかかる発明が開示されている。 In addition, the invention concerning the following patent documents is disclosed as a technique relevant to this invention.

特開平８−３１５０１８号公報Japanese Patent Laid-Open No. 8-315018 特開平１１−１７５６１２号公報JP-A-11-175612

上記の製番管理とＭＲＰを併用する方式としては、定期的に在庫等に引当てられた製番を外した上で、ＭＲＰによりその時点での数量を見直し、再度製番引当を見直す処理を行う方法がある。このような処理により生産計画と部材調達の最適化を行うことが可能であり、ＭＲＰの実施頻度を高めるためにＭＲＰを高速化することが技術的な課題とされていた。 As a method of using the above-mentioned production number management and MRP together, the production number regularly reserved for inventory, etc. is removed, the quantity at that time is reviewed by MRP, and the production number allocation is reviewed again. There is a way to do it. With such processing, it is possible to optimize production planning and material procurement, and it has been a technical problem to speed up MRP in order to increase the frequency of MRP implementation.

しかしながら、この見直しはバッチ処理として定期的に実施しなければならないが、異なる部署が担当している調達や払い出しなどの一連の業務をリアルタイムで同期をとりながら把握することは困難であるために、夜間や早朝など通常の業務時間外にしかバッチ処理を行うことができない。従って、最短でも一日一回しか行うことができないという問題を有しており、生産工程に大きな変更があったとしても、それを即時に部材調達に反映することができないという問題を有している。 However, this review must be carried out periodically as a batch process, but it is difficult to grasp a series of operations such as procurement and withdrawal that are handled by different departments in real-time synchronization. Batch processing can only be performed outside normal business hours, such as at night or early morning. Therefore, it has a problem that it can be performed only once a day at the shortest, and even if there is a major change in the production process, it cannot be immediately reflected in the procurement of parts. Yes.

また、見直し処理は全ての部材を対象に、生産計画まで立ち戻って行われる。しかしながら、計画時以降は変更が起こりにくいなど頻繁に製番引当の見直しを行う必要がない部材についても生産計画に立ち戻って処理を行うため、必要以上にデータ処理量が大きくなりシステムの負担が増大するという問題も有している。 In addition, the review process is performed by returning to the production plan for all members. However, since it is difficult to change after planning, it is necessary to return to the production plan for parts that do not need to be reviewed frequently, so the data processing amount becomes larger than necessary and the burden on the system increases. It also has the problem of

本発明はこのような課題に対応して、日常的な業務に対応して部材毎に個別に製番引当の処理を行い、計画変更を即時に部材調達に反映し、かつシステムの負担を軽減することを目的とする引当実行プログラム、引当実行システム、及び引当実行方法を提供しようとするものである。 In response to such problems, the present invention individually handles the production number allocation for each member in response to daily work, immediately reflects the plan change in the member procurement, and reduces the burden on the system.

入力装置１０は、構成マスターファイル１１、品目マスターファイル１２又は製造計画ファイル１３に対して、初期条件の設定や計画の進捗状況など、必要なデータを入力する機能を備えている。 The input device 10 has a function of inputting necessary data such as initial condition setting and plan progress to the configuration master file 11, item master file 12, or manufacturing plan file 13.

特に本発明においては、入力装置１０には図２の例に示すような引当方式設定のための入力画面が設けられており、部材の品目毎に「引当方式」として引当を実行するタイミングを入力することができる。「引当方式」の欄には、図２のように「計画」「発注」など、予め定められた項目の中から選択して入力できるよう構成してもよい。 In particular, in the present invention, the input device 10 is provided with an input screen for setting the allocation method as shown in the example of FIG. 2, and the timing for executing the allocation as the “allocation method” is input for each item of the member. can do. In the “allocation method” column, it is possible to select and input from predetermined items such as “plan” and “order” as shown in FIG.

構成マスターファイル１１には、製造計画を展開するために必要な製品毎の所要部材についてのデータが記録されている。図３の例であれば、製品Ｘ１個について部品Ａ２個、部品Ｂ３個、部品Ｃ４個から構成されており、歩留まり等を考慮すると実際の製造で手当が必要な数量は、部品Ａ３個、部品Ｂ４個、部品Ｃ５個となっている。 In the configuration master file 11, data on necessary members for each product necessary for developing the production plan is recorded. In the example of FIG. 3, the product X is composed of two parts A, three parts B, and four parts C, and considering the yield, etc., the quantity that needs to be paid in actual manufacturing is three parts A, parts B4 pieces and parts C5 pieces.

品目マスターファイル１２には、使用する部材の品目毎に部材の属性やコード番号などが記録されている。本発明においては、図４の例の通り品目毎に「引当方式」を記録する欄が設けられており、生産管理システムの利用者は、部材の性質に合わせて最も適当な引当のタイミングを設定することができる。 The item master file 12 records member attributes, code numbers, and the like for each member item to be used. In the present invention, as shown in the example of FIG. 4, a column for recording “allocation method” is provided for each item, and the user of the production management system sets the most appropriate allocation timing according to the property of the member. can do.

図４の例では、引当方式と併せて、品目毎に引当、解除、再引当のタイミングについても記録されている。例えば部品Ａについては計画作成時に製番引当を行い、その後の製番の見直しは行わないが、部品Ｃについては計画作成時に製番引当を行うが、当該部品の出庫時に製番を解除して、消費時に再度適当な製番を引当てる再引当作業を行う。一般に、一旦作成した計画を変更することが少ない部材には前者が適しているし、歩留まりや加工手順の関係で計画通りの数量で消費されにくい部材には後者が適している。 In the example of FIG. 4, in addition to the allocation method, the timing of allocation, cancellation, and re-allocation for each item is also recorded. For example, for part A, the production number is reserved when the plan is created and the subsequent production number is not reviewed. For part C, the production number is reserved when the plan is created, but the part number is released when the part is issued. Then, a re-allocation operation is performed to allocate an appropriate product number again at the time of consumption. In general, the former is suitable for a member that rarely changes a plan once created, and the latter is suitable for a member that is difficult to be consumed in a planned quantity due to the yield and processing procedure.

尚、それぞれの引当方式における引当、解除、再引当のタイミングについても入力装置１０から利用者が入力して定義するように構成してもよいが、処理の効率を向上させるためには、引当方式と関連付けて予め設定されていることが望ましい。 The timing of allocation, cancellation, and re-allocation in each allocation method may be configured to be input and defined by the user from the input device 10, but in order to improve the processing efficiency, the allocation method It is desirable that it is set in advance in association with.

製造計画ファイル１３には、製番毎に部材の調達計画についてのデータが管理されている。入力装置１０から製品の種類と製造個数が入力されると、構成マスターファイル１１を参照して所要部材とそれぞれの所要量を算出し、部材の調達計画を作成する。ここには、品目マスターファイル１２を参照して、それぞれの部材の引当方式についての情報も記録しておく。 In the production plan file 13, data on a material procurement plan is managed for each product number. When the type and number of products manufactured are input from the input device 10, the required members and the respective required amounts are calculated with reference to the configuration master file 11, and a member procurement plan is created. Here, the item master file 12 is referred to, and information on the allocation method of each member is also recorded.

図５は製造計画ファイル１３の一例を示したものである。製品Ｘを１０個製造する計画について、製番＃０３が付されている。所要量の欄は構成マスターファイル１１を参照して算出されるが、同一品目の部材についての在庫残と発注残を参照して引当を行い、製番＃０３を製造するために調達が必要な計画量を算出する。 FIG. 5 shows an example of the manufacturing plan file 13. The production number # 03 is assigned to a plan for producing 10 products X. The required amount column is calculated with reference to the configuration master file 11, but it is necessary to procure in order to make the production number # 03 by making a reservation with reference to the remaining inventory and the remaining order for the members of the same item. Calculate the planned amount.

在庫残については、在庫情報ファイル１５を参照する。図６は在庫情報ファイル１５の一例を示したものであるが、部材コード００１について見ると、（１）の２０個は製番＃０１で使用予定として引当済であるため「引当区分」の欄が「引当」となっているが、（２）の１０個について使用予定のない「未引当」の状態となっている。この（２）について「引当区分」の欄を「引当」に書き換えることにより使用予定を記し、製造計画ファイル１３の「在庫残」の欄に使用可能な１０個が記録される。 For the remaining inventory, the inventory information file 15 is referred to. FIG. 6 shows an example of the inventory information file 15. Looking at the member code 001, since 20 of (1) are already reserved for use with the production number # 01, the column of “Allocation” Is “allocated”, but “10” in (2) is in an “unallocated” state that is not scheduled to be used. With respect to (2), the use schedule is recorded by rewriting the “reserve category” column to “reserve”, and 10 usable items are recorded in the “stock remaining” column of the manufacturing plan file 13.

在庫残を参照した後は、発注残について発注情報ファイル１６を参照する。図７は発注情報ファイル１６の一例を示したものであるが、部材コード００１について発注済分については全て引当済となっており、ここでは製番＃０３についての引当は行われない。その結果、製造計画ファイル１３の「発注残」は０個となり、所要量の３０個から在庫から引当てた１０個を減じた２０個が、新たに発注が必要な計画量となる。 After referring to the remaining inventory, the order information file 16 is referred to regarding the remaining order. FIG. 7 shows an example of the ordering information file 16, but all of the part code 001 that has been ordered is already reserved, and no provision is made for the production number # 03 here. As a result, the “order remaining” in the manufacturing plan file 13 becomes zero, and 20 pieces obtained by subtracting 10 pieces allocated from the inventory from the required quantity of 30 pieces are the planned quantities that need to be newly ordered.

これらの在庫残、発注残を参照して引当を行うタイミングは、製造計画ファイル１３に記録された「引当方式」により決定される。引当方式で指定されたタイミングに到達すると、制御装置１４によって上記のように在庫残、発注残を参照して引当を行う処理が実行される。尚、引当のタイミングを製造計画ファイル１３に品目毎に記録する他、部材コードから品目マスターファイルを参照してそれぞれ引当のタイミングを判断するよう構成してもよい。 The timing for making an allocation with reference to the remaining inventory and the remaining order is determined by the “allocation method” recorded in the manufacturing plan file 13. When the timing specified by the allocation method is reached, the control device 14 executes a process for allocating with reference to the remaining inventory and the remaining order as described above. In addition to recording the allocation timing for each item in the manufacturing plan file 13, the allocation timing may be determined by referring to the item master file from the member code.

「引当方式」を「消費時」と設定した場合は、在庫情報ファイル１５への記録は、図６の（４）のように行われる。計画当初には製番＃０３に対して引当てられているが、部材が出庫された時点で「製番」の欄から＃０３が消去されて引当が解除される。その上で再度製番へのひも付けを行い、イレギュラーな割り込み注文で部材が不足している場合などには、当該部材も前倒しで消費され、消費の時点で新たに製番＃０２が記録される。 When “allocation method” is set to “during consumption”, recording in the inventory information file 15 is performed as shown in (4) of FIG. At the beginning of the plan, the allocation is made for the production number # 03, but when the member is delivered, # 03 is deleted from the “production number” column and the provision is released. After that, the production number is linked again, and if there are insufficient parts due to an irregular interrupt order, the parts are also consumed ahead of time, and the production number # 02 is newly recorded at the time of consumption. Is done.

尚、上記の例では在庫残、発注残について未引当分から引当を行うこととしているが、生産計画を組む前に中間品の先行手配を行なっている場合のように、製番を付与せずに計画段階で発注を予定している部材の中に残余があるような場合は、これらの部材のデータを記録した計画情報ファイルを作成し、当該計画情報ファイルを参照して、未引当の部材から引当を行うよう構成してもよい。 In the above example, the remaining inventory and the remaining order are allocated from the unallocated portion. However, as in the case where the advance arrangement of the intermediate product is performed before the production plan is made, the production number is not assigned. If there is a remainder in the parts that are scheduled to be ordered at the planning stage, create a plan information file that records the data for these parts and refer to the plan information file from the unallocated parts. You may comprise so that allocation may be performed.

また、製造計画ファイル１３には、図５の例においてであれば「発注量」の欄の前に「調整数」の項目を設けて、例えば引当済の部材を倉庫で壊してしまった場合には「調整数」の欄に数量を入力し、これを加えて計画数を算出するように構成してもよい。 Further, in the example of FIG. 5, the production plan file 13 is provided with an item “number of adjustments” in front of the “order quantity” column, and for example, when the allocated member is destroyed in the warehouse. May be configured to input the quantity in the “adjusted number” column and add this to calculate the planned number.

図８は、本発明の第一の実施形態についての品目別の引当実行のタイミングを示している。まず、生産管理システムの利用者は、部材の品目別に引当のタイミングを定める引当方式を設定する（Ｓ０１）。 FIG. 8 shows the timing of allocation by item for the first embodiment of the present invention. First, the user of the production management system sets an allocation method for determining the allocation timing for each item of the member (S01).

一般に、計画時点から製造計画の変更を行う必要が少ない部材については、製番引当の見直しを行わない計画時引当（Ｃ１）又は発注時引当（Ｃ２）を選択することが望ましい。計画時引当か発注時引当かについては、発注までの期間中に何度か製造計画の見直しが行なわれて点数が変更され得るような品目であれば後者が、一旦計画がされると発注まで変更される可能性の少ない品目であれば前者が適している。 In general, it is desirable to select the allocation at the time of planning (C1) or the allocation at the time of ordering (C2) in which the review of the production number allocation is not performed for the members that do not need to be changed from the planning time. As for the allocation at the time of planning or the allocation at the time of ordering, if the item can be changed by the review of the manufacturing plan several times during the period until the ordering, the latter will be changed once the planning is done The former is suitable for items that are unlikely to be changed.

製造計画を作成するタイミング（Ｔ１１）においては、計画時引当（Ｃ１）と設定された品目について、在庫残と発注残を参照して製番引当が行われる（Ｓ０２）。発注時引当（Ｃ２）と設定された品目は、所要量が計算されるのみで製番引当は行われない。部材を発注するタイミング（Ｔ１２）においては、発注時引当（Ｃ２）と設定された品目についても、製番引当が行われる。 At the timing of creating the production plan (T11), the production number is reserved with reference to the remaining inventory and the remaining order for the item set as the planned allocation (C1) (S02). For the item set as provision at the time of ordering (C2), only the required amount is calculated, and the production number is not reserved. At the timing of ordering members (T12), the production number is also reserved for the item set as the provision at the time of ordering (C2).

出庫時引当（Ｃ３）と消費時引当（Ｃ４）が設定された品目については、製造計画を作成するタイミング（Ｔ１１）又は部材を発注するタイミング（Ｔ１２）において、製番引当が行われる。定常的に未引当の在庫を確保することが望ましい品目や、計画通りの数量が消費できないような品目については、これらの設定を行なうことが望ましい。 For the items for which the provision at the time of delivery (C3) and the provision at the time of consumption (C4) are set, the production number is reserved at the timing of creating the production plan (T11) or at the timing of ordering the members (T12). It is desirable to make these settings for items for which it is desirable to regularly keep unallocated inventory or items that cannot be consumed as planned.

ここにおいて引当てられた製番は、部材を発注するための算出根拠となるものであるが、後のタイミングで当該製番を解除して新たな製番に引当てる最適化の処理を行なうため、いわば仮の製番に当るものである。 The production number allocated here is the basis for calculation for ordering the member. However, in order to perform the optimization process of releasing the production number and allocating a new production number at a later timing. In other words, it is a temporary production number.

部材が入庫するタイミング（Ｔ１３）においては、出庫時引当（Ｃ３）と設定された品目についての製番解除が行なわれる（Ｓ０４）。これらの在庫は部材が出庫されるタイミング（Ｔ１４）までの間は、製番が付与されずにＭＲＰ等の方式により総量での管理が行なわれて、出庫のタイミング（Ｔ１４）で再度最適化のための製番引当が行われる（Ｓ０５）。 At the timing (T13) when the member enters, the product number is canceled for the item set as the provision at the time of delivery (C3) (S04). These stocks are managed by the total amount by a method such as MRP without assigning a product number until the timing when the member is delivered (T14), and optimized again at the delivery timing (T14). The production number is reserved for this purpose (S05).

また、部材が出庫されるタイミング（Ｔ１４）においては、消費時引当（Ｃ４）が設定された品目についての製番解除が行なわれる（Ｓ０６）。部材が消費されるタイミング（Ｔ１５）までの間は、製番が付与されずにＭＲＰ等の方式により総量での管理が行なわれて、消費のタイミング（Ｔ１５）で再度最適化のための製番引当が行われる（Ｓ０７）。 In addition, at the timing (T14) when the member is delivered, the product number is released for the item for which the provision for consumption (C4) is set (S06). Until the timing when the member is consumed (T15), the production number is not assigned and the total amount is managed by a method such as MRP, and the production number for optimization again at the consumption timing (T15). Provision is made (S07).

図９は、本発明の第二の実施形態についての品目別の引当実行のタイミングを示している。この実施形態においては、出庫時引当（Ｃ３）と消費時引当（Ｃ４）が設定された品目についても、製番引当の処理はそれぞれ設定されたタイミングで一度行なわれるのみであり、第一の実施形態のような仮製番の付与と解除は行なわれない。 FIG. 9 shows the timing of allocation by item for the second embodiment of the present invention. In this embodiment, for the items for which the provision at the time of delivery (C3) and the provision at the time of consumption (C4) are set, the production number allocation process is performed only once at the set timing, and the first implementation The provisional production number is not assigned or released as in the form.

この実施形態においても、業務の流れに対応して部材毎に最適のタイミングで製番引当を行うことができるが、部材によっては発注段階においては全く製番の付与がされていないものが存在し、製番管理とＭＲＰ等を併用して管理しなければならず、計画全体の把握がしにくいという問題がある。 In this embodiment as well, the production number can be allocated at the optimum timing for each member corresponding to the flow of work, but there are some members for which no production number is assigned at the ordering stage. There is a problem that it is difficult to grasp the entire plan because the production number management and MRP must be managed together.

図１０を用いて、本発明において計画時引当を選択した場合の引当実行のフローについて説明する。生産管理システムの利用者は、ある部材についての引当方式に「計画時」を選択すると（Ｓ１１）。品目マスターファイルに、当該部材についての引当方式が「計画時」と記録される（Ｓ１２）。 With reference to FIG. 10, the flow of allocation execution when the planned allocation is selected in the present invention will be described. The user of the production management system selects “at the time of planning” as an allocation method for a certain member (S11). In the item master file, the allocation method for the member is recorded as “at the time of planning” (S12).

製造計画が作成されると、当該計画の内容とその製番が入力され（Ｓ１３）、構成マスターファイルを参照して必要な部材の数量を算出し、製造計画ファイルに計画が展開される（Ｓ１４）。「計画時」に引当を行うことが設定されているので、製番引当を行うために、この時点で同一品目についての在庫情報が参照される（Ｓ１５）。 When the production plan is created, the contents of the plan and its production number are input (S13), the quantity of necessary members is calculated with reference to the configuration master file, and the plan is developed in the production plan file (S14). ). Since it is set to allocate at “at the time of planning”, the inventory information for the same item is referred to at this time in order to allocate the production number (S15).

在庫情報ファイルでは、未引当の在庫があるか否かが確認され（Ｓ１６）、在庫がある場合にはその部材について在庫情報ファイルに引当済として製番の記録がされ（Ｓ１７）、製造計画ファイルに在庫残として引当てた数量の記録がされる（Ｓ１８）。未引当の在庫がない場合にはこのステップを経ないで、同一品目についての発注情報が参照される（Ｓ１９）。 In the inventory information file, it is confirmed whether or not there is unallocated inventory (S16). If there is inventory, the production number is recorded as allocated in the inventory information file for the member (S17), and the production plan file The quantity reserved as inventory remaining is recorded (S18). If there is no unallocated inventory, the ordering information for the same item is referred to without going through this step (S19).

発注情報ファイルでも、未引当の発注残があるか否かが確認され（Ｓ２０）、発注残がある場合にはその部材について発注情報ファイルに引当済として製番の記録がされ（Ｓ２１）、製造計画ファイルに発注残として引当てた数量の記録がされる（Ｓ２２）。未引当の在庫がない場合にはこのステップを経ないで、製造計画ファイルにおいて調達が必要な計画量が算出される（Ｓ２３）。 Also in the order information file, it is confirmed whether there is an unallocated order remaining (S20). If there is an remaining order, the part number is recorded as reserved in the order information file for the member (S21), and the manufacturing is performed. The quantity allocated as the remaining order is recorded in the plan file (S22). If there is no unallocated inventory, this step is not performed, and the planned amount that needs to be procured in the manufacturing plan file is calculated (S23).

次に、図１１を用いて、本発明において出庫時引当を選択した場合の引当実行のフローについて説明する。生産管理システムの利用者は、ある部材についての引当方式に「出庫時」を選択すると（Ｓ３１）。品目マスターファイルに、当該部材についての引当方式が「出庫時」と記録される（Ｓ３２）。 Next, with reference to FIG. 11, a flow of allocation execution when the allocation at the time of shipping is selected in the present invention will be described. The user of the production management system selects “when leaving” as the allocation method for a certain member (S31). In the item master file, the allocation method for the member is recorded as “at the time of delivery” (S32).

製造計画が作成されると、当該計画の内容とその製番として＃２が入力され（Ｓ３３）、構成マスターファイルを参照して必要な部材の数量を算出し、製造計画ファイルに計画が展開される（Ｓ３４）。「出庫時」に引当を行うことが設定されているが、この「計画時」の段階でも発注や管理の便宜のために製番引当を行う。この時点で、同一品目についての在庫情報が参照される（Ｓ３５）。 When the production plan is created, # 2 is input as the content of the plan and its production number (S33), the quantity of necessary members is calculated with reference to the configuration master file, and the plan is developed in the production plan file. (S34). It is set to allocate at “at the time of delivery”, but at the stage of “at the time of planning”, the production number is allocated for convenience of ordering and management. At this time, the inventory information for the same item is referred to (S35).

その後に在庫情報ファイル、発注情報ファイルを参照して計画量を算出するフローについては、第一の実施形態と同様である（Ｓ３６〜Ｓ４３）。但し、ここで引当てられた製番はあくまでも管理上の仮の製番である。 The flow for calculating the planned quantity with reference to the inventory information file and the ordering information file thereafter is the same as in the first embodiment (S36 to S43). However, the production numbers allocated here are only temporary production numbers for management.

次に、当該部材が入庫されると、在庫情報ファイルに記録された製番＃２が消去され、製番が解除された状態となる（Ｓ４４）。その後から出庫時まではＭＲＰ等の方式により在庫が管理され、製番＃２からの出庫指示の前に製番＃１からの出庫指示を受信すると（Ｓ４５）、在庫情報ファイルには新たな製番として＃１が記録され引当が確定する（Ｓ４６）。 Next, when the member is received, the production number # 2 recorded in the inventory information file is deleted, and the production number is released (S44). After that, the inventory is managed by a method such as MRP from the time of delivery. When the delivery instruction from the production number # 1 is received before the delivery instruction from the production number # 2 (S45), a new product is stored in the inventory information file. # 1 is recorded as the number, and the provision is fixed (S46).

さらに、その後に製番＃２からの出庫指示を受信した時には（Ｓ４７）、既に当初製番＃２に引当てられていた部材は出庫されているため、その後に入庫した部材に製番＃２が記録される（Ｓ４８）。このようなフローにより、業務の進捗に併せて、部材毎に適切なタイミングで引当の最適化を行うことが可能になる。 Furthermore, when a delivery instruction from the production number # 2 is subsequently received (S47), since the members that have already been allocated to the production number # 2 have already been delivered, the production number # 2 is assigned to the members that are subsequently received. Is recorded (S48). With such a flow, it becomes possible to optimize the allocation at an appropriate timing for each member in accordance with the progress of the work.
