[0002] 環境問題に対する人々の意識は、年々高まってきており、環境問題は、社会全体と して取り組むべき課題となっている。そのような中、環境問題に対する意識が高い生 産企業は、環境への負荷を小さくするため、ライフサイクルを終えた製品を回収して 再利用する体制を構築しつつある。このような企業の自発的な動きだけでなぐすで に一部の産業機器においては企業目標として一定の再利用率を定めることを促進す る省令が発令されており、再利用を前提とした生産体制の構築が必要となってきてい る。  [0002] People's awareness of environmental issues has been increasing year by year, and environmental issues have become a challenge for society as a whole. Under such circumstances, producers with a high awareness of environmental issues are building a system to collect and reuse products that have finished their life cycle in order to reduce environmental impact. A ministerial ordinance that promotes the establishment of a certain reuse rate as a corporate goal has been issued for some industrial equipment as a result of the voluntary movement of such companies. It is necessary to build a production system.
[0003] また、回収された製品に含まれる部品の中には、プリント基板など適正な処理を行 わないと環境に負荷力 Sかかる物質を用いてレ、る部品もある。そのような部品につレ、て は再利用するしないに関わらず、環境負荷物質を分解して取り出すことが望まれる。  [0003] In addition, among the parts contained in the collected products, there are parts that use substances that have an impact on the environment unless proper processing is performed, such as printed circuit boards. Regardless of whether such parts are reused, it is desirable to disassemble and remove environmentally hazardous substances.
[0004] 従来、リサイクル部品の利用に関しては、新しい製品を生産する場合の部品の発注 量決定方法として、部品を抽出することができる使用済み製品の回収台数を予測し、 使用済み製品の予測台数力も抽出することができるリサイクル部品の数を算出し、算 出されたリサイクル部品の数と、部品の在庫数と、総生産計画とに基づいて部品の発 注量を決定するとレ、うものがある（例えば、特許文献 1参照）。  [0004] Conventionally, regarding the use of recycled parts, as a method for determining the order quantity of parts when producing new products, the number of used products that can be extracted is predicted, and the estimated number of used products Calculate the number of recycled parts that can also extract power, and determine the order quantity of parts based on the calculated number of recycled parts, the number of parts in stock, and the total production plan. Yes (see, for example, Patent Document 1).
[0005] また、リサイクルシステムとしては、回収される使用済み製品の数量が、回収時期の 予測に反してずれた場合でも、リサイクル製品の生産計画が確実に実行できる計画 修正機能を備えたリサイクルシステムがある（例えば、特許文献 2参照）。  [0005] In addition, as a recycling system, a recycling system with a plan correction function that can reliably execute a production plan for recycled products even if the quantity of used products collected is shifted against the forecast of the collection time. (For example, refer to Patent Document 2).

発明が解決しょうとする課題  Problems to be solved by the invention
[0007] 使用済みとなり回収した製品は、例えば、中間品まで分解して再利用してもよぐそ の中間品をさらに細かい中間品や部品にまで分解して再利用してもよい場合が数多 く存在する。上述した技術は、回収した使用済み製品を、いつ、どの段階まで分解す るかを定めることまでは考慮されていなレ、。つまり、生産計画から分解計画へのフィー ドバックはなく、回収した製品は、全て分解することを想定しているものであった。その ため、分解後のリサイクル部品の使用予定の有無とは関係なく分解作業が行われる 可能 '性があった。 [0007] For example, there are a number of cases where a product that has been used and collected can be disassembled into an intermediate product and reused, and the intermediate product can be disassembled into finer intermediate products and parts for reuse. Many exist. The above-mentioned technology does not take into account the determination of when and to what level the collected used product will be disassembled. In other words, there was no feedback from the production plan to the disassembly plan, and all the collected products were supposed to be disassembled. For this reason, there was a possibility that disassembly work would be done regardless of whether or not the recycled parts after disassembly were planned to be used.
[0008] また、予め決められた再利用率を満たし、かつ不要な分解作業を行わずになるべく 上位の中間品の状態で再利用することが重要である。  [0008] In addition, it is important to satisfy the reuse rate determined in advance and to reuse in the state of a higher intermediate product as much as possible without performing unnecessary disassembly work.
[0009] 本発明は、このような点を鑑みてなされたものであり、その目的は、回収した使用済 み製品に含まれる部品や材料の予め決められた再利用率を満たしつつ、使用済み 製品の分解作業量を必要最小限に抑える分解計画、および、この分解計画と整合 性がとれ消費コストの和が最小となるように生産、調達計画を作成する方法、ならび に装置を提供することにある。  [0009] The present invention has been made in view of the above points, and its purpose is to satisfy the predetermined reuse rate of parts and materials contained in the collected used products while being used. To provide a disassembly plan that minimizes the amount of product disassembly work, and a method and equipment for creating a production / procurement plan that is consistent with this disassembly plan and minimizes the sum of consumption costs. It is in.
[0010] また、上述した技術は、設備や作業員などのリソースの使用可能量を考慮していな いため、生産要求量がある期間に集中した場合、リソース不足で想定していた時期 に生産や分解作業ができなレ、可能性がある。  [0010] In addition, since the above-described technology does not consider the usable amount of resources such as equipment and workers, if the production demand is concentrated in a certain period, There is a possibility that it cannot be disassembled.
[0011] そこで、本発明の第 2の目的は、リソースの制約の範囲で目標再利用率を満足し、 力つ消費コストの和が最小となるように生産 ·分解 ·再生 '調達品目（製品、中間品、 部品）の日別数量を算出する計画方法および装置を提供することにある。  [0011] Therefore, the second object of the present invention is to produce, disassemble, and regenerate 'procured items (products) so that the target reuse rate is satisfied within the scope of resource constraints and the sum of the powerful consumption costs is minimized. It is to provide a planning method and apparatus for calculating daily quantities of intermediate products and parts).
[0012] また、適正な処理を行わないと環境に負荷を与える物質を含有する部品（以下、要 適正処理品目と称す）については、生産工程での再利用はないが分解作業は必須 である。  [0012] In addition, parts that contain substances that cause environmental impact if not properly treated (hereinafter referred to as properly treated items) are not reused in the production process, but they must be disassembled. .
[0013] そこで、本発明の第 3の目的は、要適正処理品目を取り出すための日別分解'再生 数量を算出する計画方法および装置を提供することにある。 課題を解決するための手段 [0013] Accordingly, a third object of the present invention is to provide a planning method and apparatus for calculating the daily disassembly / regeneration amount for taking out the necessary processing items. Means for solving the problem
[0014] 上記課題を解決するため、本発明は、回収製品の回収予定数量と、調達により使 用することができるようになる部品毎の利用可能日と数量と、製品を必要とする要求 日と数量の情報である生産要求量とが入力されると、予め定められた制約条件に基 づいて線形計画法アルゴリズムに基づく計算を行い、分解、再生、生産、調達品目 の数量を出力するようにしたものである。制約条件としては、製品の生産に用いる部 品のうち回収製品から取り出して製品再利用された部品の割合を示す再利用率に関 する情報が含まれ、再利用率に関する情報に基づいて分解、再生、生産、調達品目 の数量を出力する。また、制約条件には回収した製品の分解、再生処理の際に消費 するコストおよび製品の生産、部品の調達に要するコストに関する情報が含まれ、消 費コストに関する情報に基づいて分解、再生、生産、調達品目の数量を出力する。 発明の効果 [0014] In order to solve the above-mentioned problems, the present invention provides a scheduled collection quantity of a collected product, an availability date and quantity for each part that can be used by procurement, and a request date that requires the product. And the required production quantity, which is quantity information, is calculated based on the linear programming algorithm based on predetermined constraints, and outputs the quantities of disassembly, reproduction, production, and procurement items. It is a thing.

発明を実施するための最良の形態  BEST MODE FOR CARRYING OUT THE INVENTION
[0016] 以下、本発明の実施の形態を図面を用いて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0017] 図 1は、製品の生産および再利用の流れを示す図である。 FIG. 1 is a diagram showing a flow of product production and reuse.
[0018] まず、製品の生産および再利用の流れについて図 1を用いて説明する。 [0018] First, the flow of product production and reuse will be described with reference to FIG.
[0019] 本実施の形態においては、分解して再利用することをリユース、再生して再利用す ることをリサイクルと呼び、リユースとリサイクルの総称として再利用という言葉を用いる In this embodiment, disassembly and reuse is called reuse, and recycling and reuse is called recycling, and the term reuse is used as a general term for reuse and recycling.
[0020] 製品を生産する会社は、まず製品の生産に必要な部品を調達する（101)。そして 、調達した部品から中間品を生産し（102)、さらに中間品や部品、材料を組み合わ せてさらに上位の中間品の生産を行う（103)。そしてこの中間品から製品の生産を 行い（104)、製品を出荷する（105)。製品は顧客に届けられる（106)。製品が顧客 のもとで使用済みとなると、その製品は回収される（107)。そして、回収された使用済 みの製品は、製品から中間品、部品へと分解される（108 110)。 [0020] A company that produces a product first procures parts necessary for producing the product (101). Then, intermediate products are produced from the procured parts (102), and intermediate products, parts, and materials are combined to produce higher intermediate products (103). Then, products are produced from these intermediate products (104), and the products are shipped (105). The product is delivered to the customer (106). When the product is used up by the customer, it is collected (107). The collected used products are then disassembled from products into intermediate products and parts (108 110).
[0021] ここで、再利用には、製品を分解して取り出した上位の中間品（112)の状態で用い る場合、さらに分解した下位の中間品 113の状態で用いる場合、部品、部材（114、 115)まで分解して生産に再利用する場合がある。部材にまで分解する例としては、 パソコンの筐体などがある。プラスチックでできた部品は、ー且粉碎、融解してプラス チックの粒として再生し、この粒から部品を再生して生産に再利用する。 Here, for reuse, the product is used in the state of the upper intermediate product (112) taken out by disassembling the product. In the case of use in the state of the further disassembled lower intermediate product 113, parts and members (114, 115) may be disassembled and reused for production. An example of disassembling even a member is a personal computer housing. Parts made of plastic are crushed, melted and regenerated as plastic grains, and the parts are regenerated from these grains for reuse in production.
[0022] このように、分解と再生が多段階で構成される場合、できるだけ上位の中間品で再 利用できれば分解の作業量が少なくて済むという利点がある。逆に、部品まで分解 すれば、再利用できる可能性が高いという利点がある。コストを抑えながら、 目標とす る再利用率を満足するような生産を行うためには、生産対象の製品に応じて、分解、 再生作業を決定するのが望ましい。 [0022] As described above, when the disassembly and regeneration are configured in multiple stages, there is an advantage that the amount of disassembly work can be reduced if it can be reused as a higher intermediate product as much as possible. Conversely, if parts are disassembled, there is an advantage that they can be reused. In order to carry out production that satisfies the target reuse rate while keeping costs down, it is desirable to decide the disassembly and regeneration work according to the product to be produced.
[0023] 一般的な生産、調達計画および分解再生計画の作成について図 2を用いて説明 する。 [0023] The creation of a general production, procurement plan, and disassembly / regeneration plan will be described with reference to FIG.
[0024] 図 2は、製品の生産、調達計画および回収製品の分解、再生計画を作成する装置 の位置付けを説明する図である。  FIG. 2 is a diagram for explaining the positioning of a device for creating a product production, a procurement plan, a disassembly of a collected product, and a regeneration plan.
[0025] 図 2に示すように、一般的には生産する製品の需要予測 201をもとに、生産、調達 計画装置 202で、部品調達、中間品生産計画、製品生産計画を作成する。そして、 これとは独立して使用済み製品の回収予測 203をもとに分解、再生計画装置 204で 製品、中間品の分解計画、および部品の再生計画を作成していた。このような構成 のため、生産の状況にあわせて回収製品をどこまで分解し何をいくつ取り出すのかを 決めることができず、回収した製品を予め決めておいた状態（一定の中間品または部 品）まで機械的に分解、再生をおこなっていた。  As shown in FIG. 2, generally, based on the demand forecast 201 of the product to be produced, the production / procurement planning device 202 creates parts procurement, intermediate product production plan, and product production plan. Independently of this, a disassembly / regeneration planning device 204 creates a disassembly plan for products and intermediate products, and a recovery plan for parts based on the used product recovery forecast 203. Because of this structure, it is not possible to decide how far the collected product is to be disassembled and how many are to be taken out according to the production situation, and the state of the collected product is determined in advance (certain intermediate products or parts) Until then mechanically disassembled and regenerated.
[0026] また、図 2に示すような一般的な構成では、生産に使った部品のうち再利用品が占 める割合である再利用率（リユース'リサイクル率）は、生産時点での再生品の在庫量 に依存している。そのため生産、調達計画と分解、再生計画が同期していないので、 環境対応などで再利用率の目標を掲げて製品を生産しなければならない場合、その 再利用率を考慮した生産計画を立案するようにはなっていない。  [0026] Also, in the general configuration shown in Fig. 2, the reuse rate (reuse 'recycling rate), which is the proportion of reused parts among the parts used in production, is regenerated at the time of production. It depends on the quantity of goods in stock. For this reason, the production, procurement plan, disassembly, and regeneration plan are not synchronized, so if a product must be produced with the goal of the reuse rate in order to respond to the environment, a production plan that takes into account the reuse rate is formulated. It's not like that.
[0027] 一方、本発明の一実施形態の生産、調達計画および分解、再生計画の作成につ いて図 3を用いて説明する。  On the other hand, production, procurement plan and disassembly, and creation of a regeneration plan according to an embodiment of the present invention will be described with reference to FIG.
[0028] 図 3は、本発明の一実施形態における製品の生産、調達計画および回収製品の分 解、再生計画を作成する装置の位置付けを説明する図である。 [0028] FIG. 3 illustrates product production, procurement planning, and collection of collected products according to an embodiment of the present invention. It is a figure explaining the positioning of the apparatus which produces a solution and a reproduction | regeneration plan.
[0029] 図 3に示すように、本実施の形態においては、生産する製品の需要予測 201と回収 予測 203とに基づき、決められた再利用率目標（リユース'リサイクル率目標） 312と、 生産や調達、分解や再生により消費するコスト 313とを考慮し、分解、生産、調達計 画装置 300にて、生産、調達計画と分解、再生計画とを整合性をとつて作成する。  [0029] As shown in FIG. 3, in the present embodiment, the reuse rate target (reuse 'recycling rate target) 312 determined based on the demand forecast 201 and the recovery forecast 203 of the product to be produced, and production In consideration of the cost 313 consumed by procurement, disassembly, and regeneration, the disassembly, production, and procurement planning device 300 prepares the production, procurement plan and disassembly and regeneration plan in a consistent manner.
[0030] なお、本実施の形態においては、上述したように再利用のうち、分解して再利用す ることをリユース、再生して再利用することをリサイクルと呼ぶ。そして、再利用率をリ ユース、リサイクルごとに管理することを前提とする。リユース、リサイクルの区別をしな レ、で再利用率を管理する場合でも、本発明にて考慮することは可能である。  In the present embodiment, as described above, out of reuse, disassembling and reusing is referred to as reuse, and regenerating and reusing is referred to as recycling. It is assumed that the reuse rate is managed for each reuse and recycling. Even when the reuse rate is managed with no distinction between reuse and recycling, it can be considered in the present invention.
[0031] 一般に、回収する製品および生産する製品は複数種類あり、部品構成も多段で複 雑な構成をしている。実際の製品を扱うには膨大な処理を必要とする。本実施例で は、本発明の内容を明確に示すために、製品の種類、部品構成を単純化して説明 する。  [0031] In general, there are a plurality of types of products to be collected and products to be produced, and the parts configurations are multi-stage and complicated. Handling an actual product requires a huge amount of processing. In this embodiment, in order to clearly show the contents of the present invention, the types of products and the component configurations will be described in a simplified manner.

[0051] ここでは AP01、 AP02、 AP03が回収製品である。部品構成ツリー 1000の下の表 1001は、分解する親部品 1002と、親部品 1002から取り出せる子部品 1003と、取り 出せる子部品 1003の数 1004と、親部品 1002から子部品 1003を取り出すまでのリ ードタイム 1005とを示している。例えば AP01からはリードタイム 1日で A00、 A01、 A02、 A03をそれぞれ 1単位ずつ分解して取り出すことができることを示している。ま た、その下の再生の表 1006は、再生する親部品 1007と、親部品 1007を再生する のに必要な子部品 1008と、再生に必要な子部品 1008の数 1009と、子部品 1008 力 親部品 1007を再生するまでのリードタイム 1010とを示している。例えば AP03を 2単位、 Al lを 3単位組み合わせて R23をリードタイム 1日で再生することができるこ とを示している。この図 5に示すデータは、リサイクル部品表記憶部 402に記憶されて いる。 [0051] Here, AP01, AP02, and AP03 are collected products. The table 1001 under the parts structure tree 1000 shows a parent part 1002 to be disassembled, a child part 1003 that can be taken out from the parent part 1002, a number 1004 of child parts 1003 that can be taken out, and a list of the parts from the parent part 1002 until the child part 1003 is taken out. The dead time is 1005. For example, from AP01, A00, A01, It shows that A02 and A03 can be disassembled and taken out one unit at a time. Also, the playback table 1006 below shows the parent part 1007 to be played back, the child parts 1008 required to play back the parent part 1007, the number of child parts 1008 required for playback 1009, and the child parts 1008 force. The lead time 1010 until the parent part 1007 is regenerated is shown. For example, 2 units of AP03 and 3 units of Al 1 can be combined to play R23 with a lead time of 1 day. The data shown in FIG. 5 is stored in the recycled parts table storage unit 402.
[0052] 次に、本実施形態における生産製品の部品構成について説明する。  [0052] Next, the component configuration of the production product in the present embodiment will be described.
[0053] 図 6は、本実施形態における生産製品の部品構成および生産リードタイムを示す図 である。 FIG. 6 is a diagram showing the component configuration and production lead time of the production product in the present embodiment.
[0054] 図 6に示す部品構成ツリー 1020において、 P +番号は生産製品を示している。 i + 番号は中間品を、 B +番号は部品を示している。部品構成ツリー 1020の下の表 102 1は、生産する親部品 1022と、親部品 1022を生産するのに必要な子部品 1023と、 生産に必要な子部品 1023の数 1024と、子部品 1023から親部品 1022を生産する までのリードタイム 1025とを示している。例えば生産製品 P01は、中間品 il lおよび 部品 Bl l、 B12から構成されており、生産リードタイムは 1日である。この図 6に示す データは、部品表記憶部 405に記憶されている。  [0054] In the component structure tree 1020 shown in FIG. 6, the P + number indicates a production product. The i + number indicates an intermediate product, and the B + number indicates a part. Table 102 1 below the parts structure tree 1020 shows the parent part 1022 to be produced, the child parts 1023 required to produce the parent part 1022, the number of child parts 1023 required to produce 1024, and the child parts 1023 The lead time 1025 until the parent part 1022 is produced is shown. For example, the production product P01 is composed of the intermediate product il l and the parts Bl l and B12, and the production lead time is one day. The data shown in FIG. 6 is stored in the parts table storage unit 405.
[0055] 回収製品の部品表を示す図 5に戻り、図 5の楕円で囲んでいる部品 A12は、図 6の 生産製品の楕円で囲んでいる部品 B12にリユースできるリュース品である。 P01は、 中間品 il l、および 2つの部品 B11、A12のから生産することができる。同様に、図 5 の四角で囲んでいる部品 R13、 R23はそれぞれ図 6の四角で囲んでいる部品 B13、 B23にリサイクルすることができるリサイクル品である。これらの互換性関係情報は互 換性情報記憶部 410に記憶されている。なお、互換性関係情報は 1対 1でなぐ 1対 nでもよレ、。例えば、パソコンを生産する場合に、 128MBのメモリを必要とする場合、 その容量が 128MB以上であればよいのなら、リユース可能な部品は複数となる。  [0055] Returning to FIG. 5 showing the parts table of the collected product, the part A12 surrounded by the ellipse in FIG. 5 is a loose product that can be reused as the part B12 surrounded by the ellipse of the production product in FIG. P01 can be produced from the intermediate product il l, and two parts B11, A12. Similarly, the parts R13 and R23 enclosed by the square in FIG. 5 are recycled products that can be recycled to the parts B13 and B23 enclosed by the square in FIG. 6, respectively. Such compatibility relationship information is stored in the compatibility information storage unit 410. Note that the compatibility information may be 1 to 1 instead of 1 to 1. For example, if you need 128MB of memory to produce a personal computer, if the capacity is 128MB or more, there are multiple reusable parts.
[0056] 図 5の回収製品の部品表において下線でマークした部品 A03は、図 6の生産製品 のどの部品とも互換性がないが、要適正処理品目として指定されているものである。 このデータは要適正処理品目記憶部 415に記憶されている。 [0057] 生産、分解、再生をするために必要となる設備や人などのリソース量に関して 1日に 使用可能なリソース量が限られている場合には、リソース情報記憶部 413に品目ごと に生産、分解、再生をするために必要となるリソースとその量を登録し、各リソースの 日別の使用可能量をリソース能力情報記憶部 413に登録しておく。 [0056] The part A03 marked with an underline in the parts list of the collected product in FIG. 5 is not compatible with any part of the production product in FIG. 6, but is designated as an appropriate processing item. This data is stored in the proper processing item storage unit 415. [0057] When the amount of resources that can be used per day is limited in terms of the amount of resources such as equipment and people required for production, disassembly, and regeneration, production is performed for each item in the resource information storage unit 413. Then, the resource and the amount required for disassembly and reproduction are registered, and the daily usable amount of each resource is registered in the resource capability information storage unit 413.
[0058] 次に、コスト情報について図 7および図 8を用いて説明する。  Next, cost information will be described with reference to FIGS. 7 and 8.
[0059] 図 7において、表 1030は、分解する親部品の品目 1031と、親品目 1031から取り 出せる子部品の品目 1032と、親品目 1031から子品目 1032を取り出す分解作業の 際に消費される分解コスト 1033とを示している。また、表 1034は、再生品の品目 10 35と、再生品目 1035の再生作業の際に消費される再生コスト 1036とを示している。  [0059] In FIG. 7, table 1030 is consumed during the disassembling operation to extract the parent part item 1031 to be disassembled, the child part item 1032 to be extracted from the parent item 1031, and the child item 1032 from the parent item 1031. The decomposition cost is 1033. Table 1034 also shows the recycled item 1035 and the recycling cost 1036 consumed when the recycled item 1035 is recycled.
[0060] 図 8において、表 1040は、生産する親部品の品目 1041と、親品目 1041の生産に 必要な子部品の品目 1042と、子品目 1042を親品目 1041に取り付ける際に消費さ れる生産コスト 1043とを示している。また、表 1044は、調達品の品目 1045と、調達 品目 1045の調達作業の際に消費される調達コスト 1046とを示している。  [0060] In FIG. 8, Table 1040 shows the parent part item 1041 to be produced, the child part item 1042 required to produce the parent item 1041, and the production consumed when the child item 1042 is attached to the parent item 1041. Cost 1043 is shown. Table 1044 shows the item 1045 of the procurement item and the procurement cost 1046 consumed when the procurement item 1045 is procured.
[0061] 図 7において、分解コスト 1033は、親品目 1031を分解して子品目 1032を 1単位 取り出すのに必要となるコストである。例えば 1つの親から子を 2つ取り出すと、コスト は 2倍になる。また、図 8において、生産コスト 1043は、親品目 1041に子品目 1042 を 1単位組み付けるのに必要となるコストである。新品を組み付ける場合と、再利用品 を組み付ける場合との生産コストとが異なっていてもよレ、。この図 7、図 8に示すコスト 情報は、コスト情報記憶部 408で記憶されてレ、る。  In FIG. 7, the disassembly cost 1033 is a cost required to disassemble the parent item 1031 and take out one unit of the child item 1032. For example, taking two children from one parent doubles the cost. In FIG. 8, the production cost 1043 is a cost required for assembling one unit of the child item 1042 to the parent item 1041. The production cost may differ between when installing a new product and when using a reusable product. The cost information shown in FIGS. 7 and 8 is stored in the cost information storage unit 408.
[0062] 本実施の形態では、 目標リユース率、 目標リサイクル率は、製品 P01、 P02合計で 20%とする。 目標リユース率、 目標リサイクル率は、製品別、もしくは今回の例のよう に製品をグノレープ化した製品群別に設定し、その値は期間ごとに異なる率を設定で きる。 列えば、製品 P01は、 4月 1日力、ら 9月 30日は 20%、 10月 1日力ら 3月 31日ま では 10%などと設定できる。このデータは記憶部 407にて記憶されている。  [0062] In the present embodiment, the target reuse rate and the target recycling rate are 20% in total for products P01 and P02. The target reuse rate and target recycling rate can be set for each product or for each product group that has been gnoraped as in this example, and different values can be set for each period. For example, the product P01 can be set to 20% on April 1st, 20% on September 30th, and 10% on October 1st until March 31st. This data is stored in the storage unit 407.
[0063] 次に、回収予定情報について説明する。  Next, the collection schedule information will be described.
[0064] 図 9は、回収予定記憶部 401に記憶される回収予定情報を示す図である。  FIG. 9 is a diagram showing the collection schedule information stored in the collection schedule storage unit 401.
[0065] 図 9において、表 1050は、回収済製品 1051と、回収済製品 1051の在庫数量 10 52とを示してレ、る。また、表 1053は、回収製品 1054と、回収製品 1054の回収予定 数量 1055と、回収製品 1054の回収予定日 1056とを示してレヽる。 In FIG. 9, a table 1050 shows the collected product 1051 and the inventory quantity 1052 of the collected product 1051. Table 1053 shows the recovered product 1054 and the recovery plan of recovered product 1054 Shows the quantity 1055 and the scheduled collection date 1056 for the collected product 1054.
[0066] 回収済み製品 1051は分解および再生する可能性のある製品である。図 9に示す 例では、在庫数量 1052が「0」なので、回収済み在庫はない。回収製品 1054の AP 01は 4月 11日に 100個回収する予定である。図 9に示すデータのうち、回収済み在 庫のデータ（表 1050)は在庫記憶部 403で記憶され、回収予定のデータ（表 1054) は回収予定記憶部 401で記憶されている。 [0066] The recovered product 1051 is a product that may be decomposed and regenerated. In the example shown in Fig. 9, the inventory quantity 1052 is “0”, so there is no collected inventory. 100 AP 01 recovered products will be collected on April 11th. Of the data shown in FIG. 9, the collected inventory data (table 1050) is stored in the inventory storage unit 403, and the recovery schedule data (table 1054) is stored in the recovery schedule storage unit 401.
[0067] 一方、生産要求情報の方を次に見てみる。 [0067] On the other hand, the production request information will be examined next.
[0068] 図 10は、在庫情報（表 1060)、入庫予定情報（表 1063)、生産要求情報（表 1067 [0068] Figure 10 shows inventory information (Table 1060), warehousing schedule information (Table 1063), production request information (Table 1067).
)を示す図である。 FIG.
[0069] 表 1060は、製品や製品の生産に必要となる部品等の品目 1061と、品目 1062の 在庫数量 1062とを示している。表 1063は、製品や製品の生産に必要となる部品等 の品目 1064と、品目 1064の人庫予定量 1065と、品目 1064の人庫予定曰 1066と を示してレ、る。そして、表 1067は、製品 1068と、製品 1068の生産要求数量 1069と 、製品 1068の生産要求曰 1070とを示してレヽる。  [0069] Table 1060 shows the items 1061 such as products and parts required for the production of the products, and the inventory quantity 1062 of the item 1062. Table 1063 shows the items 1064 such as products and parts necessary for the production of the product, the planned occupancy amount 1065 of the item 1064, and the planned occupancy rate 1066 of the item 1064. Table 1067 shows the product 1068, the production requirement quantity 1069 of the product 1068, and the production requirement 1070 of the product 1068.
[0070] 図 10に示す例では、製品 1068の P01は 4月 7日に生産要求が 50個ある。製品の 在庫および製品の生産に必要となる部品等の在庫や入庫予定量は「0」である。図 1 0に示すデータのうち、在庫のデータ（表 1060)は在庫記憶部 403で記憶され、入庫 予定のデータ（表 1063)は入庫予定情報記憶部 404で記憶され、生産要求のデー タ（表 1067)は生産要求記憶部 406で記憶されている。この生産要求情報と図 7に 示した回収予定情報とに基づいて、計画立案部 411が生産、分解、再生、調達計画 を作成する。  [0070] In the example shown in FIG. 10, P01 of product 1068 has 50 production requests on April 7. The inventory of products and the parts inventory required for product production and the expected amount of receipt are “0”. Of the data shown in Fig. 10, inventory data (Table 1060) is stored in the inventory storage unit 403, and planned storage data (Table 1063) is stored in the storage schedule information storage unit 404, and production request data ( Table 1067) is stored in the production request storage unit 406. Based on the production request information and the collection schedule information shown in FIG. 7, the planning unit 411 creates a production, disassembly, regeneration, and procurement plan.
[0071] 計画立案部 411における生産、分解、再生、調達計画の作成ステップについて次 に説明する。  [0071] Production, disassembly, regeneration, and procurement plan creation steps in the planning unit 411 will be described next.
[0072] 生産、分解、再生、調達計画の作成ステップは、大きくは以下のステップ 1一 3から なる。  [0072] The production, disassembly, regeneration, and procurement plan creation steps generally consist of the following steps 1 to 13.
[0073] ステップ 1：入力情報の読み込み  [0073] Step 1: Reading input information
ステップ 2：制約条件のモデル生成  Step 2: Constraint model generation
ステップ 3 :最適化計算 各ステップにおける処理内容を以下に述べる。 Step 3: Optimization calculation The processing contents in each step will be described below.
[0074] まず、ステップ 1の処理内容は以下の通りである。  [0074] First, the processing content of step 1 is as follows.
<ステップ 1 >  <Step 1>
前述の入力情報を記憶する記憶部より計算に必要な情報をメモリ上に読み込む。  Information necessary for calculation is read into the memory from the storage unit storing the input information.
[0075] このとき、分解、再生する可能性がある製品（以下の説明においては品目と称する） の在庫および回収予定のデータと、生産要求のデータとが両方ともない場合、生産、 分解、再生、調達するものがないとみなし、処理を終了する。 [0075] At this time, if there is no inventory and collection schedule data of a product that may be disassembled and regenerated (referred to as an item in the following description) and production request data, production, disassembly, remanufacture, It is assumed that there is nothing to procure, and the process is terminated.
[0076] 次に、ステップ 2の処理内容を説明する。 Next, the processing content of step 2 will be described.
<ステップ 2 >  <Step 2>
ステップ 2では、ステップ 3の最適化計算にインプットするためのモデルを生成する。  In step 2, a model is generated for input to the optimization calculation in step 3.
[0077] 本発明では、線形計画法アルゴリズムを最適化計算に利用する。線形計画法は、 制約条件と目的関数を線形方程式で記述し、制約条件を満たす解集合の中から目 的関数が最適となる解を検索するものである。 In the present invention, a linear programming algorithm is used for optimization calculation. Linear programming is a method in which constraints and objective functions are described by linear equations, and a solution with an optimal objective function is searched from a set of solutions that satisfy the constraints.
[0078] 図 11に、本発明の一実施形態における制約条件を模式的に表した図を示す。 FIG. 11 is a diagram schematically showing the constraint conditions in one embodiment of the present invention.
[0079] 各品目について、その役割に応じて日別の変数を定義する。例えば、品目 AP01 について変数となるのは、在庫量、出庫量、 AP01から分解した A01の量、 A01の分 解量、入庫量、在庫量、出庫量、 A01から分解した A12の量である。図 11で四角で 囲んで示している「回収」「入庫予定」は、記憶部より入力した定数であることを示して レ、る。四角で囲まれてレ、なレ、文字は変数であることを示してレ、る。 [0079] For each item, a daily variable is defined according to its role. For example, for the item AP01, the variables are inventory quantity, delivery quantity, A01 quantity disassembled from AP01, A01 disassembly quantity, receipt quantity, inventory quantity, delivery quantity, and A12 quantity disassembled from A01. “Recovery” and “entry scheduled” shown in the box in FIG. 11 are constants input from the storage unit. Surrounded by squares, it indicates that characters are variables.
[0080] 図 11において、モノの流れを矢印で表わす。モノの流れ方に従属して変数の値を 決める必要があるので、おのおのの変数を結ぶ矢印を 1つの制約条件として記述す る必要がある。矢印と変数との関係は、以下の 4パターンの制約条件で記述できる。 In FIG. 11, the flow of things is represented by arrows. Since it is necessary to determine the value of the variable depending on the flow of things, it is necessary to describe the arrow connecting each variable as one constraint condition. The relationship between arrows and variables can be described by the following four patterns of constraints.
[0081] 一つ目の制約条件は在庫制約である。 [0081] The first constraint condition is an inventory constraint.
(1)在庫制約  (1) Inventory constraints
品目の在庫は、入庫量と出庫量と入庫予定量で記述する。例えば、図 11の A02に 関しては、  The stock of the item is described by the amount of goods received, the amount of goods delivered, and the expected amount of goods received. For example, for A02 in Figure 11,
t日在庫量 = t_l日在庫量 + t日入庫量 + t日入庫予定量一 t日出庫量 が成り立たなければならない。 [0082] 二つ目の制約条件は部品構成制約である。 t-day stock quantity = t_l daily stock quantity + t-day receipt quantity + t-day receipt quantity 1 t-day delivery quantity. [0082] The second constraint condition is a component configuration constraint.
(2)部品構成制約  (2) Component configuration constraints
品目の親子関係は、図 5、図 6に示すような親子関係であると定義する。そうすると、 例えば、図 11の P01を 1単位作るためには、 1日前に il lが 1単位必要となるので、 The parent-child relationship of items is defined as the parent-child relationship shown in Figs. Then, for example, to make 1 unit of P01 in Fig. 11, 1 unit of il l is needed 1 day ago.
P01の t日の生産量 = il lの t_l日の消費量 P01 t-day production = il l t_l-day consumption
と記述する。 B11のように、複数の製品で消費される場合には、  Is described. When consumed by multiple products, such as B11,
B11の t日の消費量 = P01の t + 1日の生産量 + P02の t + 1日の生産量 と記述する。  B11 t-day consumption = P01 t + daily production + P02 t + daily production.
[0083] 例えば、 AP01から A01を 1単位取り出すことができるので、  [0083] For example, since A01 can be taken out from AP01,
AP01の t日の分解量≥l X t + l日に AP01から分解した A01の量 と記述する。ここで分解の場合、親品目から全ての子品目と取り出すとは限らないの で、不等式となっている。  Decomposition amount of AP01 on day t ≥l X t + lday Describe the amount of A01 decomposed from AP01. Here, in the case of disassembly, not all child items are extracted from the parent item, so it is an inequality.
[0084] 三つ目の制約条件は引当制約である。 [0084] The third constraint condition is an allocation constraint.
(3)引当制約  (3) Provision restrictions
分解、再生した品目が何に使えるのかを記述する。例えば、図 11で AP01から分 解した A02は、再生の材料として使用されるので、  Describe what the disassembled and recycled items can be used for. For example, A02 disassembled from AP01 in Fig. 11 is used as a material for regeneration.
t日に AP01から分解した A02の量 =A02の t日の入庫量  The amount of A02 disassembled from AP01 on day t = the amount of goods received on day t of A02
もし、分解場所と再生場所が離れていて、輸送するのに日数力 Sかかるならば、その 日数分だけオフセットすればレ、い。例えば輸送に 3日力かるなら、上式は、  If the disassembly site and the recycling site are far apart and it takes several days S to transport, offset by that number of days. For example, if it takes 3 days to transport, the above equation is
t日に AP01から分解した A02の量 =A02の t + 3日の入庫量  A02 amount disassembled from AP01 on day t = A02 t + amount of goods received on day 3
となる。  It becomes.
[0085] 四つ目の制約条件は生産要求量引当制約である。  The fourth constraint condition is a production request amount allocation constraint.
(4)生産要求量引当制約  (4) Restriction on production requirement allocation
製品を生産した量は、生産要求量を満たしたいので、例えば、図 11では、 P01の t日出荷量 = P01の t日生産要求量（S111)  The amount of product produced wants to meet the production requirement. For example, in Fig. 11, t01 shipment quantity for P01 = tproduction requirement quantity for P01 (S111)
と記述する。ところ力 リードタイムの関係や、回収量の関係で、この等式条件が常に 成り立つとは限らない。そこで、生産要求量に対して出荷量の不足量を変数として定 義し、 P01の t日出荷量 + P01の t日出荷未達量 =P01の t日生産要求量（S111) と記述し、等式条件が常に成り立つようにする。 Is described. However, this equality condition does not always hold due to the relationship between the force lead time and the recovery amount. Therefore, the shortage of the shipment amount is defined as a variable with respect to the production requirement amount, Describe P01 t-day shipment amount + P01 t-day shipment unachieved amount = P01 t-day production requirement (S111) so that the equality condition always holds.
[0086] (1) (2) (3) (4)の制約条件により、生産要求量 (S111)が与えられると、従属的に 変数の値を決めることができる。  [0086] (1) (2) (3) Given the production requirement (S111), the variable values can be subordinately determined according to the constraints of (4).
[0087] 次に、上記 4つの制約条件にさらに追加する制約条件を説明する。 [0087] Next, constraint conditions to be added to the above four constraint conditions will be described.
[0088] 生産 S113、 S114、分角军 S115、 S116、再生 S117を行うために必要となる設備や 人などのリソース量に対し、 1日に使用可能な量が限られている場合には、制約条件 (5)を更に追加する。 [0088] If the amount of resources that can be used in one day is limited to the amount of resources such as equipment and people required to perform production S113, S114, squeeze S115, S116, and regeneration S117, Add further constraint (5).
(5)リソース制約  (5) Resource constraints
例えば、生産 S113で、設備を使って生産を行う場合には、  For example, in production S113, when production is performed using equipment,
il 1を 1単位生産する際の設備占有時間 X il 1の t日入庫量≤設備の t日稼動 時間  Equipment occupancy time for producing 1 unit of il 1 X il 1 t-day receipt amount ≤ equipment t-day operation time
と記述する。設備を複数の品目で共有する場合には、各品目の設備占有時間 X入 庫量を左辺に加算する。  Is described. When sharing equipment with multiple items, add the equipment occupation time X receipt amount of each item to the left side.
[0089] 次に、 目標リュース率、 目標リサイクル率について説明する。  [0089] Next, the target loose rate and the target recycling rate will be described.
[0090] 本発明では、変数の値を決めるパラメータとして、 目標リュース率、リサイクル率を 与える。リユース率、リサイクル率は、製品の生産に対する分解および再生量を生産 に引き当てた量の割合で記述するので次のようになる。  In the present invention, a target loose rate and a recycle rate are given as parameters for determining the value of the variable. The reuse rate and recycle rate are described as follows as the ratio of the amount of decomposition and recycling to the production is allocated to production.
[0091] (分解量を生産に引き当てた量） ÷ (製品の生産量） =目標リユース率 [0091] (Amount of decomposition allocated to production) ÷ (Production amount) = Target reuse rate
(再生量を生産に引き当てた量） ÷ (製品の生産量） =目標リサイクル率 割合を求めるための「量」は、個数でもよいし、重量などの別の基準に換算した量で もよレ、。なお、この制約条件も、回収量の与え方によっては、 目標となる量に必ずしも 一致しないことがあるので、 目標を超過した引当量、 目標に満たない引当量変数を 定義して、  (Recycled amount assigned to production) ÷ (Product production amount) = Target recycling rate The “quantity” for determining the ratio may be the number or the amount converted to another standard such as weight. ,. Note that this constraint may not always match the target amount depending on how the collection amount is given, so the provision amount exceeding the target and the provision amount variable that does not meet the target are defined.
(分解量を生産に引き当てた量一目標を超過した引当量 +目標に満たない引当 量）  (Amount allocated to production for the amount of decomposition) Provision amount exceeding the target + Provision amount less than the target)
÷ (製品の生産量） =目標リユース率  ÷ (Product production volume) = Target reuse rate
と記述する。 [0092] 次に、 目的関数を定義する。本実施形態においては、コスト、 目標リュース、リサイ クル率、生産要求の充足度を計画の評価指標とする。 Is described. [0092] Next, an objective function is defined. In the present embodiment, the cost, the target screw, the recycling rate, and the satisfaction level of the production request are used as the evaluation indexes for the plan.
[0093] コストは、今回の例では分解量、再生量、生産量、調達量にそれぞれ分解コスト、 再生コスト、生産コスト、調達コストを乗算することで計算できる。別のコストとして、在 庫コストや輸送コストなども考慮することができる。例えば、在庫コストは在庫量に単 位あたり在庫コストを乗算すればよい。在庫コストを導入すれば、生産のタイミングに あわせて分解や再生の作業を行うような結果が得られる。以上のコストの和がなるベ く小さくなればよい。  In this example, the cost can be calculated by multiplying the disassembly amount, the regeneration amount, the production amount, and the procurement amount by the disassembly cost, the regeneration cost, the production cost, and the procurement cost, respectively. Other costs include inventory costs and transportation costs. For example, the inventory cost can be obtained by multiplying the inventory quantity by the inventory cost per unit. If inventory costs are introduced, results can be obtained in which disassembly and recycling work is performed in accordance with the timing of production. The sum of the above costs should be as small as possible.
