Description

本発明は、商品の受注を受け付けて、引当処理を行う受注引当システム及び方法並びにプログラムに関する。   The present invention relates to an order allocation system, method, and program for receiving an order for a product and performing an allocation process.

余分な在庫を無くし生産量を最適化できるようにした種々の生産管理システムや在庫管理システムが提案されている。例えば、特許文献１には、複数の工程からなる生産ラインの全工程を管理して、顧客の希望納期に応じた請納期を決定でき、請納期の順出と適正な仕込みの指示を行うことができるようにしたものが提案されている。また、特許文献２には、各在庫ポイントにおける在庫発生量を求め、在庫コストを算出することで、少ない負担でサプライチェーンの評価を行うことができるようにしたものが提案されている。また、特許文献３には、指定された予定生産量及び製品ライフサイクルと、特徴情報と、特注情報とに基づいて、生産対象物を生産する際の生産方式を決定して、複数の生産方式が混在した生産過程での生産管理を行うようにしたものが提案されている。   Various production management systems and inventory management systems have been proposed that can eliminate excess inventory and optimize production. For example, in Patent Document 1, all processes in a production line composed of a plurality of processes can be managed, and a delivery date can be determined according to a customer's desired delivery date. There is a proposal that can do this. Further, Patent Document 2 proposes a method in which a supply chain can be evaluated with a small burden by obtaining an inventory generation amount at each inventory point and calculating an inventory cost. Further, in Patent Document 3, a production method for producing a production object is determined based on a designated scheduled production amount and product life cycle, characteristic information, and custom information, and a plurality of production methods are determined. Proposals have been made to carry out production management in a production process in which a mixture of products is present.

一般的に、在庫管理システムでは、商品の受注を受けると、引当てが可能であるかどうかを判定し、受注の納期に間に合わないときには、生産調整を行っている。すなわち、商品の受注を受けたとき、もし在庫があれば、その在庫から受注を受けた分の商品を、その出荷先分の商品として確保できる。このように、在庫から商品を確保することを、以下、在庫に対する引当てと称する。また、在庫はなくとも、納期までに、その商品を生産できれば、その商品を納入できる。そこで、商品の受注を受けたら、生産予定の商品から、受注を受けた分の商品をその出荷先分の商品として確保する。このように、生産予定の商品から、その出荷先への商品を確保することを、以下、生産予定に対する引当てと称する。   Generally, in an inventory management system, when an order for a product is received, it is determined whether allocation is possible. If the delivery date of the order is not met, production adjustment is performed. That is, when an order for a product is received, if there is a stock, the product for which the order has been received from the stock can be secured as the product for the shipping destination. In this manner, securing the product from the inventory is hereinafter referred to as allocation for the inventory. Even if there is no inventory, if the product can be produced by the delivery date, the product can be delivered. Therefore, when an order for a product is received, the product for the order received is secured as the product for the shipping destination from the products scheduled to be produced. In this way, securing the product to the shipping destination from the product scheduled to be produced is hereinafter referred to as provision for the production schedule.

現状では、一旦、引当てを行った商品はそのまま確保し、新たに受けた受注が引き当て不可になったら、生産調整を行っている。ところが、引当てが不可であっても、新たに受けた受注より納期の遅い他の同一商品受注との引当て調整で、賄える場合がある。この場合、生産調整を行うと、最終的に余分な在庫として残ってしまう。また、他の同一商品受注との引当て調整で賄えないとしても、納期の遅い受注で生産調整を行えば、商品納期に間に合う可能性が高くなる。   At present, once allocated products are secured as they are, and when new orders cannot be allocated, production adjustment is performed. However, even if allocation is not possible, there may be cases where it is possible to cover by order adjustment with other orders for the same product whose delivery date is later than the newly received order. In this case, if production adjustment is performed, it will eventually remain as an excess inventory. In addition, even if it is not possible to cover for other orders for the same product, it is more likely that the product will be delivered in time if production adjustment is performed with an order with a later delivery date.

上述の課題を鑑み、本発明は、引当てを無駄なく行えると共に、引当てできない場合にも、商品納期に間に合う可能性が高くできるようにした受注引当システム及び方法並びにプログラムを提供することを目的とする。   In view of the above-described problems, the present invention has an object to provide an order reservation system, method, and program which can perform allocation without waste and can increase the possibility of being in time for delivery of goods even when allocation is not possible. And

上述の課題を解決するために、本発明は、受注を受け付ける入力手段と、受け付けた受注に対して引当処理を行うデータ処理手段と、引当状態の結果を表示する表示手段とを備え、データ処理手段は、引当てが行えない場合に、既に引当て済みの受注を解除して、引当ての最適化を行うことを特徴とする受注引当システムである。   In order to solve the above-described problems, the present invention includes an input unit that receives an order, a data processing unit that performs an allocation process for the received order, and a display unit that displays a result of the allocation state. The means is an order allocation system characterized in that, when allocation cannot be performed, an already allocated order is canceled and allocation is optimized.

本発明は、受注を受け付けると、生産予定に対する引当て、在庫に対する引当ての順に引当処理を行い、引当部による引当てが行えない場合に、既に引当て済みの受注を解除して、同一の商品について、納期の遅いものから納期の早いものの順に、生産予定に対する引当て、在庫に対する引当ての順に第１段階の引当ての最適化を行い、さらに、第１段階の引当の最適化が行えない場合に、既に引当て済みの受注を解除して、納期の早いものから納期の遅いものの順に、在庫に対する引当て、生産予定に対する引当ての順に第２段階の最適化を行うことを特徴とする受注引当方法である。   In the present invention, when an order is received, the allocation process is performed in the order of the allocation for the production schedule and the allocation for the inventory. When the allocation by the allocation unit cannot be performed, the already allocated order is canceled and the same For products, the first stage of allocation is optimized in the order of the allocation to the production schedule and the allocation to the inventory in the order from late delivery to early delivery, and further optimization of the first stage can be performed. In the case where there is not, the order that has already been allocated is canceled, and the second stage of optimization is performed in the order of the allocation to the inventory and the allocation to the production schedule in the order from early delivery to late delivery. This is an order reservation method.

本発明によれば、受注の入力を受けると、生産予定に対する引当てを行い、次に、在庫に対する引当てを行う。ここで、引当てができない場合、既に引当て済みの受注を解除して、第１段階の最適化を行う。第１の段階の最適化では、受注のタイミングによらず、同一の商品について、納期の遅いものから早いものの順に、生産予定に対する引当てを行い、在庫に対する引当てを行う。受注のタイミングによる引当てを解除して、納期の遅いものから早いものの順に、生産予定に対する引当てを行い、在庫に対する引当てを行うと、納期の遅いものに対しては、可能な限り、生産予定に対する引当てが行われ、納期の近いものに、在庫に対する引当てが行われるように最適化されるため、引当てできる可能性が高くなる。さらに、第１段階の再引当てで引当て不可の場合には、第２段階として、既に引当て済みの受注を解除して、納期の早いものから遅いものの順に、在庫に対する引当てを行い、生産予定に対する引当てを行う。そして、生産調整を指示する。納期の早いものから遅いものの順に、在庫に対する引当てを行い、生産予定に対する引当てを行うと、納期の遅いものが引当てできなくなる可能性が高い。この場合、引当てできない受注は納期が最遅となるため、生産調整ができる確率が上がる。このように、本発明によれば、引当てできる確率を向上させ、また引当て不可となった場合でも、最遅納期の受注が引当て不可となり、生産調整できる確率が向上できる。   According to the present invention, when an input of an order is received, the production schedule is allocated, and then the inventory is allocated. If the allocation cannot be made, the already allocated order is canceled and the first stage optimization is performed. In the first stage of optimization, regardless of the timing of the order, the same product is allocated to the production schedule and the inventory is allocated in the order from late delivery to early delivery. Release the provision based on the timing of the order, make provisions for the production schedule in the order from late delivery to early delivery, and reserve for inventory. Provision is made for the schedule, and optimization is performed so that the provision for the inventory is made near the delivery date. Furthermore, if it is not possible to reserve in the first stage of re-allocation, as the second stage, the already allocated orders are canceled, and the inventory is allocated in the order from early to late, Reserve for production schedules. Then, production adjustment is instructed. If the inventory is allocated in the order from early delivery to late delivery and the production schedule is allocated, there is a high possibility that the late delivery date cannot be allocated. In this case, an order that cannot be allocated has the latest delivery date, so that the probability of production adjustment increases. As described above, according to the present invention, it is possible to improve the probability that allocation can be made, and even when the allocation becomes impossible, it is impossible to allocate an order for the latest delivery date, and the probability that production adjustment is possible can be improved.

The order reservation data storage device 124 includes order reservation information (order key, allocation destination (inventory / production schedule key), allocation number, etc.). The production request data storage device 125 includes production request information (delivery date, quantity, etc.).

次に、本発明の第１の実施形態の動作について説明する。受注登録部１１０は、入力装置１０１より受信した受注情報(商品コード、受注数、受注納期等)を受注データ記憶装置１２１に記憶する。   Next, the operation of the first embodiment of the present invention will be described. The order registration unit 110 stores the order information (product code, number of orders, order delivery date, etc.) received from the input device 101 in the order data storage device 121.

引当部１１１は、入力装置１０１より受信した受注情報(商品コード、受注数、受注納期等)と、在庫データ記憶装置１２２より受信した在庫数、引当済数と、生産予定データ記憶装置１２３より受信した生産予定日、生産予定数、引当済数とにより、生産予定に対する引当て及び在庫に対する引当てを行う。   The allocation unit 111 receives the order information received from the input device 101 (product code, order quantity, order delivery date, etc.), the inventory number received from the inventory data storage device 122, the reserved number, and the production schedule data storage device 123. According to the scheduled production date, planned production number, and allocated number, the production schedule and the inventory are reserved.

引当部１１１においては、引当て順番は、生産予定(未来から現在)に対する引当てを行い、次に、在庫に対する引当てを行う順で、受注数分引当てできるまで処理を行う。生産予定に対する引当ては、受注納期内に生産完了予定のもの（受注納期≧生産予定日を満たす）が対象で、生産予定数から引当済数を減算した数（引当可能数＝生産予定数−引当済数)まで引当て可能である。   In the allocation unit 111, the allocation order is performed for the production schedule (from the future to the present), and then processing is performed until the number of orders is allocated in the order in which the inventory is allocated. Provisions for production schedules are those for which production is scheduled to be completed within the delivery date of the order (satisfaction of the order delivery date ≥ the planned production date). It is possible to reserve up to the allocated number).

在庫に対する引当ては、在庫数から引当済数を減算した数（引当可能数＝在庫数−引当済数)まで引当て可能である。受注数が、生産予定及び在庫に引当てた数量の合計より大きくなった場合には、引当て不可となる。   The allocation to the inventory can be allocated up to the number obtained by subtracting the allocated number from the inventory number (allowable number = inventory number−allocated number). If the number of orders is larger than the total quantity reserved for production schedule and inventory, the allocation becomes impossible.

引当部１１１により引当てできた場合は、引当部１１１は、記憶装置１０５に対して以下処理を行う。在庫に対する引当てを行った場合には、在庫データ記憶装置１２２に対して、引当済数に在庫に引当てた数量を加算する。生産予定に対する引当てを行った場合には、生産予定データ記憶装置１２３に対して、引当済数に生産予定に引当てた数を加算する。受注引当データ記憶装置１２４に対しては、受注データ記憶装置１２１が在庫データ記憶装置１２２、生産予定データ記憶装置１２３のどこに引当てっているかの関係を記憶する。   If the allocation unit 111 has been able to allocate, the allocation unit 111 performs the following processing on the storage device 105. When the inventory is allocated, the quantity allocated to the inventory is added to the allocated number in the inventory data storage device 122. When the production schedule is allocated, the number allocated for the production schedule is added to the allocated number in the production schedule data storage device 123. The order allocation data storage device 124 stores the relationship between the inventory data storage device 122 and the production schedule data storage device 123 where the order data storage device 121 allocates.

第１の引当判断部１１７は、引当部１１１の処理結果が引当て可の場合、引当ステータスを引当更新部１１３に送信する。引当部１１１の処理結果が引当て不可の場合、引当ステータスを第１の引当最適化部１１２に送信する。   The first allocation determination unit 117 transmits the allocation status to the allocation update unit 113 when the processing result of the allocation unit 111 can be allocated. When the processing result of the allocation unit 111 cannot be allocated, the allocation status is transmitted to the first allocation optimization unit 112.

第１の引当最適化部１１２は、入力装置１０１より受信した受注と同一商品について、引当て済の受注の引当てを全て解除し、再引当処理を行う。引当ての解除は、各記憶装置に対して以下処理を行う。   The first allocation optimizing unit 112 cancels all the allocations of the allocated orders for the same products as the orders received from the input device 101, and performs the re-allocation process. The release of the allocation is performed for each storage device as follows.

受注引当データ記憶装置１２４に対して、入力装置１０１より受信した受注と同一商品の情報を削除する。在庫データ記憶装置１２２に対して、削除した受注引当データ記憶装置１２４の引当て先が在庫の場合、受注引当データ記憶装置１２４の引当数を引当済数から減算する。生産予定データ記憶装置１２３に対して、削除した受注引当データ記憶装置１２４の引当て先が生産予定の場合、受注引当データ記憶装置１２４の引当数を引当済数から減算する。   Information on the same product as the order received from the input device 101 is deleted from the order allocation data storage device 124. When the allocation destination of the deleted order allocation data storage device 124 is inventory with respect to the inventory data storage device 122, the allocation number of the order allocation data storage device 124 is subtracted from the allocated number. For the production schedule data storage device 123, when the allocation destination of the deleted order allocation data storage device 124 is a production schedule, the allocation number of the order allocation data storage device 124 is subtracted from the allocated number.

第１段階の再引当ては、以下手順で処理を行う。入力装置１０１より受信した受注と同一商品の受注を対象に、納期が遅い受注から早い受注の順番に、生産予定に対する引当てを行い、在庫に対する引当てを行う。この引当ては、前述の引当部１１１と同様の処理により実現される。   The first stage of re-allocation is performed according to the following procedure. For orders received for the same product as the orders received from the input device 101, the production schedule is allocated in the order of late orders and early orders, and the inventory is allocated. This allocation is realized by the same processing as that of the allocation unit 111 described above.

引当最適化部１１２の処理結果が引当て可の場合、第２の引当判断部１１８は、引当ステータスを引当更新部１１３に送信する。第１の引当最適化部１１２の処理結果が引当て不可の場合、引当ステータスを第２の引当最適化部１１４に送信する。   When the processing result of the allocation optimizing unit 112 can be allocated, the second allocation determining unit 118 transmits the allocation status to the allocation updating unit 113. When the processing result of the first allocation optimization unit 112 cannot be allocated, the allocation status is transmitted to the second allocation optimization unit 114.

第２の引当最適化部１１４は、入力装置１０１より受信した受注と同一商品について、引当て済の受注の引当てを全て解除し、再引当処理を行う。引当ての解除は、引当最適化部１１２と同様の処理を行う。再引当ては、以下手順で処理を行う。   The second allocation optimizing unit 114 cancels all the allocations of the allocated orders for the same products as the orders received from the input device 101, and performs the re-allocation process. The release of the allocation is performed in the same manner as the allocation optimization unit 112. The re-allocation is performed according to the following procedure.

入力装置１０１より受信した受注と同一商品の受注を対象に、納期が早い受注から納期が遅い受注の順番に、在庫に対する引当てを行い、生産予定に対する引当てを行う。引当ては、前述の引当部１１１と同様の処理で行えるが、引当て順番は、在庫に対する引当てを行い、次に、生産予定に対する引当て(現在から未来)を行うような順とする。   In the order of the same product as the order received from the input device 101, the inventory is allocated in the order from the early delivery date to the late delivery date, and the production schedule is allocated. The allocation can be performed by the same processing as that of the allocation unit 111 described above, but the allocation order is an order in which allocation is performed for inventory, and then allocation is performed for the production schedule (current to future).

第３の引当判断部１１９は、引当最適化部１１４の処理結果が引当て可の場合、引当ステータスを引当更新部１１３に送信する。第２の引当最適化部１１４の処理結果が引当て不可の場合、生産依頼部１２０に引当てでできなかった受注情報(受注納期、受注数等)を送信する。   The third allocation determination unit 119 transmits the allocation status to the allocation update unit 113 when the processing result of the allocation optimization unit 114 can be allocated. If the processing result of the second allocation optimization unit 114 cannot be allocated, order information (order delivery date, number of orders received, etc.) that could not be allocated is transmitted to the production request unit 120.

以上のように、本発明の第１の実施形態の受注引当システム１では、受注の入力を受けると、生産予定に対する引当てを行い、次に、在庫に対する引当てを行う。生産予定に対する引当ての処理では、納期までに生産される商品を対象として、商品の生産数から引当済数を除いて引当可能数を求め、引当可能数と商品の受注数とを比較し、引当可能数が受注数より大きければ、生産予定数での引当てを行う。また、在庫に対する引当ての処理では、ストックされている商品の中から既に引当て済みの商品を除いて引当可能数を求め、商品の引当可能数と商品の受注数とを比較し、引当可能数が受注数より大きければ、在庫数での引当てを行う。   As described above, in the order allocation system 1 according to the first embodiment of the present invention, when an input of an order is received, the production schedule is allocated, and then the inventory is allocated. In the allocation process for the production schedule, for the products that are produced by the delivery date, the provisionable number is obtained by subtracting the provisioned number from the number of products produced, the available number is compared with the number of orders received for the product, If the number that can be allocated is larger than the number of orders, the number of production is allocated. In addition, in the process of allocating inventory, the number of items that can be allocated is calculated by excluding products that have already been allocated from stocked products, and the number of products that can be allocated is compared with the number of orders received for products. If the number is larger than the number of orders, reserve with the number of inventory.

上述のようにして、生産予定に対する引当て又は在庫に対する引当てが行えれば、生産予定に対する商品又は在庫の商品中、引当数に相当するものの出荷先が確定する。ここで、引当てができない場合、本発明の第１の実施形態では、既に引当て済みの受注を解除して、第１段階の最適化を行う。第１の段階の最適化では、受注のタイミングによらず、同一の商品について、納期の遅いものから早いものの順に、生産予定に対する引当てを行い、在庫に対する引当てを行う。   As described above, when the allocation for the production schedule or the allocation for the inventory can be performed, the shipping destination corresponding to the allocation number among the products for the production schedule or the inventory products is determined. Here, in the case where allocation cannot be made, in the first embodiment of the present invention, the already allocated order is canceled and the first stage optimization is performed. In the first stage of optimization, regardless of the timing of the order, the same product is allocated to the production schedule and the inventory is allocated in the order from late delivery to early delivery.

受注のタイミングによる引当てを解除して、納期の遅いものから早いものの順に、生産予定に対する引当てを行い、在庫に対する引当てを行うと、納期の遅いものに対しては、可能な限り、生産予定に対する引当てが行われ、納期の近いものに、在庫に対する引当てが行われるように最適化されるため、引当てできる可能性が高くなる。   Release the provision based on the timing of the order, make provisions for the production schedule in the order from late delivery to early delivery, and reserve for inventory. Provision is made for the schedule, and optimization is performed so that the provision for the inventory is made near the delivery date.

さらに、第１段階の再引当てで引当て不可の場合には、第２段階として、既に引当て済みの受注を解除して、納期の早いものから遅いものの順に、在庫に対する引当てを行い、生産予定に対する引当てを行う。そして、生産を上げるように、生産調整を指示する。   Furthermore, if it is not possible to reserve in the first stage of re-allocation, as the second stage, the already allocated orders are canceled, and the inventory is allocated in the order from early to late, Reserve for production schedules. Then, production adjustment is instructed to increase production.

納期の早いものから遅いものの順に、在庫に対する引当てを行い、生産予定に対する引当てを行うと、納期の遅いものが引当てできなくなる可能性が高い。この場合、引当てできない受注は納期が最遅となるため、生産調整ができる確率が上がる。   If the inventory is allocated in the order from early delivery to late delivery and the production schedule is allocated, there is a high possibility that the late delivery date cannot be allocated. In this case, an order that cannot be allocated has the latest delivery date, so that the probability of production adjustment increases.

次に、図２のフローチャートを参照して本発明の第１の実施形態の動作について詳細に説明する。   Next, the operation of the first embodiment of the present invention will be described in detail with reference to the flowchart of FIG.

まず、作業者は、データ処理装置１０４の操作を開始する（ステップＢ１）。次に、作業者は、入力操作を開始し（ステップＡ１）、入力画面から受注情報を入力する（ステップＡ２）。   First, the worker starts operating the data processing device 104 (step B1). Next, the worker starts an input operation (step A1) and inputs order information from the input screen (step A2).

次に、入力した受注情報を受注登録部１１０及び引当部１１１に送信する（ステップＡ３）。次に、受注登録部１１０は、受信した受注情報を受注データ記憶装置１２１に記憶する（ステップＢ２）。   Next, the input order information is transmitted to the order registration unit 110 and the allocation unit 111 (step A3). Next, the order registration unit 110 stores the received order information in the order data storage device 121 (step B2).

次に、引当部１１１は、受信した受注情報を基に、生産予定に対する引当処理を行い、在庫に対する引当処理を行う（ステップＢ３）。引当て順番は、生産予定(未来から現在)に対する引当てを行ってから、在庫に対する引当てを行う順で、受注数分引当てできるまで処理を行う。生産予定に対する引当ては、受注納期≧生産予定日を満たす生産予定が対象で、引当可能数(＝生産予定数−引当済数)まで引当て可能である。在庫に対する引当ては、引当可能数(＝在庫数−引当済数)まで引当て可能である。受注数＞（生産予定及び在庫に引当てた数量の合計）となった場合は、引当て不可となる。   Next, the allocation unit 111 performs an allocation process for the production schedule based on the received order information, and performs an allocation process for the inventory (step B3). In the order of allocation, processing is performed in the order in which allocation is made for the production schedule (from the future to the present) and then for the number of orders received in the order of allocation for inventory. The allocation to the production schedule is for the production schedule that satisfies the order delivery date ≧ the production scheduled date, and can be allocated up to the number that can be allocated (= the number of productions−the number of allocations). The allocation to the inventory can be allocated up to the number that can be allocated (= the number of inventory-the number allocated). If the number of orders> (total of production schedules and inventory allocated), allocation is impossible.

次に、データ処理装置１０４は、引当て装置から引当て結果を受信し、正常に引当てできたか判断する（ステップＢ４）。引当て結果が引当て可であれば、記憶装置１０５への記憶を確定し、処理を終了する（ステップＢ５）。   Next, the data processing device 104 receives the allocation result from the allocation device and determines whether or not the allocation has been successfully performed (step B4). If the allocation result is acceptable, the storage in the storage device 105 is confirmed and the process is terminated (step B5).

引当て結果が引当て不可であれば、データ処理装置１０４は、第１の引当最適化部１１２に、引当て結果を送信する。次に、第１の引当最適化部１１２は、受信した引当て結果を基に、同一商品の引当て済受注全てに対して、引当ての解除、再引当処理を行う（ステップＢ６）。再引当ては、納期が遅い受注から納期が早い順番に、生産予定に対する引当てを行って、在庫に対する引当てを行う。引当処理は、ステップＢ３と同様の処理を用いる。   If the allocation result cannot be allocated, the data processing apparatus 104 transmits the allocation result to the first allocation optimization unit 112. Next, based on the received allocation result, the first allocation optimization unit 112 performs allocation cancellation and re-allocation processing for all allocated orders for the same product (step B6). In the re-allocation, the production schedule is allocated in the order from the late delivery date to the early delivery date, and the inventory is allocated. The allocation process uses the same process as in step B3.

次に、データ処理装置１０４は、第１の引当最適化部１１２から引当て結果を受信し、正常に引当てできたか判断する（ステップＢ７）。引当て結果が引当て可であれば、記憶装置１０５への記憶を確定し、処理を終了する（ステップＢ５）。   Next, the data processing apparatus 104 receives the allocation result from the first allocation optimization unit 112, and determines whether the allocation has been normally performed (step B7). If the allocation result is acceptable, the storage in the storage device 105 is confirmed and the process is terminated (step B5).

引当て結果が引当て不可であれば、データ処理装置１０４は第２の引当最適化部１１４に、引当て結果を送信する。次に、第２の引当最適化部１１４は、受信した引当て結果を基に、同一商品の引当て済受注全てに対して、引当ての解除、再引当処理を行う（ステップＢ８）。再引当ては、納期が早い受注から納期が遅い受注の順番に、在庫に対する引当てを行い、生産予定に対する引当てを行う。引当ての処理は、ステップＢ３と同様であるが、引当て順番は、在庫に対する引当てを行ってから、生産予定(現在から未来)に対する引当てを行うような順とする。   If the allocation result cannot be allocated, the data processing apparatus 104 transmits the allocation result to the second allocation optimization unit 114. Next, based on the received allocation result, the second allocation optimization unit 114 performs allocation cancellation and re-allocation processing for all allocated orders for the same product (step B8). In the re-allocation, the inventory is allocated in the order from the early delivery date to the late delivery date, and the production schedule is allocated. The allocation process is the same as in step B3, but the allocation order is such that the allocation for the inventory is performed and the allocation for the production schedule (current to future) is performed.

次に、データ処理装置１０４は、第２の引当最適化部１１４から引当て結果を受信し、正常に引当てできたか判断する（ステップＢ９）。引当て結果が引当て可であれば、記憶装置への記憶を確定し、処理を終了する（ステップＢ５）。   Next, the data processing apparatus 104 receives the allocation result from the second allocation optimization unit 114, and determines whether the allocation has been normally performed (step B9). If the allocation result is acceptable, the storage in the storage device is confirmed and the process is terminated (step B5).

引当て結果が引当て不可であれば、データ処理装置１０４は、生産依頼部１２０に引当て結果を送信する。次に、生産依頼部１２０は受信した引当て結果をもとに、引当てできなかった情報（商品コード、納期、不足数等）を生産依頼データ記憶装置１２５に記憶した後（ステップＢ１０）、各記憶装置１０５への記憶を確定し、処理を終了する（ステップＢ５）。   If the allocation result cannot be allocated, the data processing apparatus 104 transmits the allocation result to the production request unit 120. Next, the production request unit 120 stores information (product code, delivery date, number of shortages, etc.) that could not be allocated in the production request data storage device 125 based on the received allocation result (step B10), The storage in each storage device 105 is confirmed, and the process is terminated (step B5).

以上説明したように、本発明の第１の実施形態では、引当部１１１の引当処理と、第１の引当最適化部１１２による第１段階の最適化処理と、第２の引当最適化部１１４による第２段階の最適化処理との３段階の引当処理を行うように構成されている。これにより、引当てできる確率を向上させ、また引当て不可となった場合でも３段階目の引当処理で最遅納期の受注が引当て不可となり、生産調整できる確率を向上できる。   As described above, in the first embodiment of the present invention, the allocation process of the allocation unit 111, the first stage optimization process by the first allocation optimization unit 112, and the second allocation optimization unit 114 Is configured to perform a three-stage allocation process with a second-stage optimization process. As a result, the probability of allocation can be improved, and even in the case where allocation is impossible, it is not possible to allocate an order for the latest delivery date in the allocation process at the third stage, and the probability that production adjustment can be performed can be improved.

本発明は、上述した実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内で様々な変形や応用が可能である。   The present invention is not limited to the above-described embodiments, and various modifications and applications can be made without departing from the gist of the present invention.
