　図３は、生産計画立案部（工場シミュレータ）１１で使用する生産計画モデルの概要を示す説明図である。カスタマイズ製品などのような受注生産品、多品種少量生産品は、受注から出荷にわたって、受注案件別のプロジェクト型で生産される。そこで、本実施例では、例えば、プロジェクト型の日程計画手法であるＰＥＲＴ（Program Evaluation and Review Technique）に基づいて、案件別・工程別の逐次日程計画方法を採用する。 FIG. 3 is an explanatory view showing an outline of a production plan model used in the production plan planning unit (factory simulator) 11. Made-to-order products such as customized products, and high-mix low-volume products are produced in a project-type-by-order project manner, from order placement to delivery. Therefore, in the present embodiment, for example, the sequential schedule planning method by project and process is adopted based on PERT (Program Evaluation and Review Technique) which is a project type schedule planning method.
　本実施例で採用する方法では、製番または製作枝番に設定された原単位コードに基づき、各工程の単位期間当りのリソース消費量をリソース制約とみなして、各工程・リソースにおける生産負荷の山積み／山崩しを行い、平準化した計画を立案する。 In the method adopted in this embodiment, the resource consumption per unit period of each process is regarded as a resource constraint based on the basic unit code set in the serial number or production branch number, and the production load in each process / resource is Do pile up / breakdown and make a leveled plan.
　工場シミュレータ１１は、例えば、「フォワード」、「バックワード」、「ハイブリッド」のうちいずれかの方法で、案件別・工程別の日程を計画することができる。 The factory simulator 11 can, for example, plan the schedule by item or process by any one of “forward”, “backward”, and “hybrid”.
　「フォワード」とは、計画開始日から納期（計画終了日）に向かって、製番または製作枝番別の工程順序に従い、順次日程を計画する計画モードである。例えば、案件受注時や工程見直しの際の納期予測などを実施したい場合に、この計画モードを採用する。 "Forward" is a planning mode in which a schedule is sequentially planned according to the process order by manufacturing number or production branch number from the planning start date to the delivery date (plan end date). For example, this plan mode is adopted when it is desired to carry out delivery date forecasting at the time of order acceptance or process review.
　「バックワード」とは、納期から計画開始日に向かって、工程順序の逆順に遡って日程を計画するモードである。例えば納期確定後に、実行可能かつ最短の日程で生産する計画を立案したい場合に、この計画モードを採用する。 The "backward" is a mode in which the schedule is planned by going back in the reverse order of the process order from the delivery date to the planning start date. For example, this plan mode is adopted when it is desired to make a plan for production that can be performed with the shortest possible schedule after the delivery date is determined.
　「ハイブリッド（フォワード＆バックワード）」とは、工程順序の最初から途中までをフォワードで計画し、以降をバックワードで計画するモードである。例えば、設計工程をフォワードで計画して長納期部品などの先行調達を行い、加工・組立以降のモノづくり工程を納期引き付けで実施したい場合に、採用することができる。 "Hybrid (forward & backward)" is a mode in which forward planning is performed from the beginning to the middle of the process sequence, and backward planning is performed thereafter. For example, it can be adopted when planning the design process in the forward direction to advance procurement of long delivery parts etc. and implementing the manufacturing process after processing and assembly with delivery time attraction.
　図３では、計画モードとして「バックワード」を採用した例を示す。リソース消費量の計算方法を説明する。 FIG. 3 shows an example in which “backward” is adopted as the planning mode. Explain how to calculate resource consumption.
　図３（１）に示すバックワードの計画モードで計画した案件別・工程の日程に対し、各種リソースの消費量を計算する場合を説明する。ここでは、「納期（出荷）」および「総合試験工程」は割付済みであるとし、その前の工程である「単体試験」は、リードタイム（ＬＴ） が１０ 日であり、試験場Ｚ（作業エリア）を一日当たり２０ ｍ^2使用することとする。この場合、試験場Ｚ の作業エリアＡＺは、ＡＺ＝[ｕ]／[ｂｍ]×（３[ｍ]+２）として求めることができる。 The case where the consumption of various resources is calculated with respect to the schedule for each item and process planned in the backward planning mode shown in FIG. 3 (1) will be described. Here, it is assumed that “delivery time (shipment)” and “general test process” have been assigned, and the previous process “unit test” has a lead time (LT) of 10 days and test site Z (work area ) Should be used at 20 m ^ 2 per day. In this case, the work area AZ of the test site Z 1 can be obtained as AZ = [u] / [bm] × (3 [m] +2).
　ここで、リソース消費値[ｕ]は「２０ ｍ^2／台」、製作数[ｍ]は「２ 台」であり、基準台数[ｂｍ]を１ 台とすると、１６０[ｍ^2]の作業エリアＡＺを確保する必要があることがわかる。 Here, the resource consumption value [u] is “20 m ^ 2 / unit”, the production number [m] is “two”, and assuming that the reference number [bm] is one, 160 [m ^ 2] It is understood that it is necessary to secure the work area AZ.
　他リソースの消費量は、以下の通り計算することができる。「設計」工程で消費するリソース「設計部Ｘ（作番取纏）」は、例えば（製作枝番）１[件]と求められる。「加工」工程で消費するリソース「製造ラインＹ（加工時間）」は、例えば「２０ｈ／台」×「２ 台」=４０ｈとして求めらる。「組立」工程で消費するリソース「製造ラインＹ（作業時間）」は、例えば[組立計画ＳＴ]として求められる。図３の例では、「製作枝番Ｃ－１」の組立計画ＳＴ として「５０ｈ」が設定されているものとする。ＳＴとは、標準作業時間（Standard Time）を意味する。標準作業時間を標準時間と呼ぶこともできる。 Consumption of other resources can be calculated as follows. The resource consumed in the “design” process “design part X (production number)” is determined to be, for example, (production branch number) 1 [case]. The resource “production line Y (processing time)” consumed in the “processing” step is obtained, for example, as “20 h / unit” × “2 units” = 40 h. A resource “manufacturing line Y (working time)” consumed in the “assembly” process is determined as, for example, [assembly plan ST]. In the example of FIG. 3, it is assumed that "50h" is set as the assembly plan ST of "production branch number C-1." ST means standard working time (Standard Time). Standard work time can also be called standard time.
　次に、生産負荷の山積み／山崩し方法について述べる。算出されたリソース消費量（生産負荷）を各リソースに対して山積みし、生産負荷の合計値が上限値に達したかチェックし、必要に応じて生産負荷を分散させる（山崩し処理を実施する）。 Next, we will discuss how to build up / break up production load. The calculated resource consumption (production load) is accumulated for each resource, it is checked whether the total value of the production load has reached the upper limit value, and the production load is dispersed as necessary (perform the mountain collapse process) ).
　山崩しあり／山崩しなしは、リソースごとに設定可能である。「山崩しあり」に設定した場合、各リソースの上限値（図３下側のグラフ中の能力線）を超過すると、工程の割付日程を前倒し（バックワード時）、または後倒し（フォワード時）する。 There is a mountain collapse / no mountain collapse can be set for each resource. If it is set to "with a mountain collapse", when the upper limit of each resource (the capacity line in the lower graph in Fig. 3) is exceeded, the process allocation schedule is moved forward (backward) or later (forward) Do.
　これに対し、「山崩しなし」と設定した場合、各リソースの上限値を超過しても工程の割付日程は変えずに、そのまま山積みしておく。「山崩しあり」は、例えば、設備などリソース超過した場合の調整余地が少ない工程やリソースで採用することができる。「山崩しなし」は、例えば、部署間や外注などで融通が可能な工程やリソースで採用することができる。 On the other hand, when “no landslide” is set, even if the upper limit value of each resource is exceeded, the process allocation schedule is not changed, and piled up as it is. For example, “with landslide” can be adopted in a process or resource where there is little room for adjustment when resources such as facilities exceed. “No landslide” can be adopted, for example, in processes and resources that can be flexible between departments or outsourced.
　生産負荷の山積み方法は複数ある。本実施例では、図３下側のグラフ内に示すように、例えば４種類の山積み方法について説明する。グラフ中の点線のハッチングが入った領域は、他案件の工程の生産負荷で既に山積みされた領域である。これに対し、グラフ中の車線のハッチングが入った領域は、生産計画の立案対象である「製作枝番Ｃ－１」の各工程で山積みされた生産負荷の領域である。 There are multiple ways to pile up production load. In the present embodiment, as shown in the lower graph of FIG. 3, for example, four types of stacking methods will be described. The area with dotted hatching in the graph is an area that has already been stacked by the production load of the process of another project. On the other hand, the hatched area of the lane in the graph is the area of the production load piled up in each process of “production branch No. C-1” which is the target of the production plan.
　本実施例では、リソースの消費方法である山積み方法として、「全日占有型」、「全日按分型」、「前詰め型」、「初日消費型」の４種類をリソースの性質に応じて使い分けることができる。すなわち本実施例では、リソースの種類（性質）に応じて、リソースを消費するパターン（リソース消費タイプ）を予め複数用意している。これにより、リソースの種類に応じてリソース消費量を分配することができ、より適切な生産計画を作成することができる。 In this embodiment, four types of methods of consumption of resources, “all day exclusive type”, “all day allotment type”, “front-loading type”, and “first day consumption type” are used according to the nature of the resource. be able to. That is, in the present embodiment, a plurality of resource consumption patterns (resource consumption types) are prepared in advance according to the type (properties) of the resource. Thereby, resource consumption can be distributed according to the type of resource, and a more appropriate production plan can be created.
　「全日占有型」では、各工程のリードタイムの期間に対し、計算したリソース消費量（生産負荷）をそのまま山積みする。 In the "all day occupation type", the calculated resource consumption (production load) is piled up as it is for the lead time period of each process.
　リソース「設計部Ｘ（作業取纏）」の例では、設計工程のリードタイム「１０日」にわたって、１件山積みしている。このリソースは「山崩しなし」に設定されているため、上限値「１０件／日」を超過してもそのまま山積みしておく。もしも、このリソース「設計部Ｘ（作業取纏）」について「山崩しあり」と設定された場合、「バックワード」モードであれば日程の前方向に工程がシフトされ、「フォワード」モードであれば日程の後方向に工程をシフトさせて、リードタイムの全期間でリソース上限値を満たす日程となるように割り付ける。 In the example of the resource “design part X (work order)”, one is piled up over the lead time “10 days” of the design process. Since this resource is set to "no landslides", it will be piled up as it is even if the upper limit "10 cases / day" is exceeded. If this resource "design part X (work preparation)" is set as "with a mountain collapse", the process is shifted forward in the schedule in the "backward" mode, and the "forward" mode is selected. For example, the process is shifted in the backward direction of the schedule, and allocation is made so as to meet the resource upper limit value in the entire period of the lead time.
　「全日按分型」では、計算したリソース消費量（生産負荷）を各工程のリードタイムの期間で除算して１日当たりの生産負荷を算出し、各々の日付に山積みする。リソース「製造ラインＹ（加工時間）」の例では、生産負荷「４０ｈ」 を加工工程のリードタイム「５日」で除算し、１日当たり「８ｈ」の負荷を山積みする。このリソースは「山崩しあり」に設定されているため、通常であれば、払出の前日から加工が割付られる。図３の例では、リードタイムの全期間でリソース上限値を満たす日付まで前倒しされている。 In "all day apportionment type", the calculated resource consumption (production load) is divided by the lead time period of each process to calculate the production load per day, and is accumulated on each date. In the example of the resource “production line Y (processing time)”, the production load “40 h” is divided by the lead time “5 days” of the processing step, and “8 h” load per day is accumulated. Since this resource is set to "with landslide", processing is normally allocated from the day before the payout. In the example of FIG. 3, it is advanced to the date which satisfy | fills a resource upper limit in the whole period of lead time.
　「前詰め型」では、計算したリソース消費量（生産負荷）を各工程のリードタイムの期間に対し、前詰めで順次山積みする。リソース「製造ラインＹ（作業時間）」の例では、リソース消費量「５０ｈ」を前詰めで山積みしている。ここで、「山崩しあり」と設定されているとすると、リードタイムの期間で山積みしきれなかった場合、日程の前倒し／後倒しが行われる。なお、「山崩しなし」に設定された場合、リードタイムの初日に全て山積みされる。一方、「山崩しあり」に設定された場合、リードタイム期間の前の日付から順にリソース消費量が入る分だけ山積みされていく。ここで、リードタイム期間でリソース消費量を山積みしきれない場合は、日程の前倒し（バックワード時）／後倒し（フォワード）を実行する。 In the "front-loading type", the calculated resource consumption (production load) is stacked in a front-loading manner with respect to the lead time period of each process. In the example of the resource "production line Y (working time)", the resource consumption amount "50 h" is piled up on the front. Here, if it is set as "falling mountain", if it is not possible to pile up in the lead time period, the schedule will be moved forward / backward. In addition, if it is set to "no mountain collapse", all will be piled up on the first day of the lead time. On the other hand, if it is set to "due", the resource consumption will be stacked in order from the date before the lead time period. Here, if the resource consumption can not be piled up in the lead time period, the schedule is moved forward (at the time of backward) / reversed (forward).
　「初日消費型」では、計算したリソース消費量（生産負荷）を各工程の初日に全て山積みする。「初日消費型」は、例えば、各工程の投入量を制御する場合などに採用することができる。「初日消費型」方式は、リードタイム期間の初日に全て山積みし、「山崩しあり」に設定された場合は、日程の前倒し（バックワード時）／後倒し（フォワード）を実行する。 In the "first day consumption type", the calculated resource consumption (production load) is piled up on the first day of each process. The “first day consumption type” can be adopted, for example, when controlling the input amount of each process. In the "first day consumption type" method, all are piled up on the first day of the lead time period, and when it is set to "with a mountain collapse", the schedule is moved forward (backward) / backward (forward).
　なお、図３では記載を省略しているが、前後の工程間に所定時間（例えば、所定日数）の空き日程を設けることもできる。例えば、「調達」から「払出」までの間に部品納入日の変動リスクを吸収するための空き日程を設けたり、「組立」から「単体試験」までの間に製品搬送を行うための空き日程を設けたりしてもよい。ここで「払出」とは、対象の製品を生産するのに必要な部品やユニットを供給することを意味する。 In addition, although description is abbreviate | omitted in FIG. 3, the vacant schedule of predetermined time (for example, predetermined days) can also be provided between process back and front. For example, a vacant schedule for absorbing the fluctuation risk of parts delivery date between “Procurement” and “Payout”, and a vacant schedule for carrying out product transportation between “Assembly” and “Single unit test”. May be provided. Here, "dispensing" means supplying parts and units necessary to produce a target product.
　図４は、生産計画立案支援処理のフローチャートである。本処理は、生産計画立案支援システム１のマイクロプロセッサ１０１がコンピュータプログラム１０３１を実行することにより実現される。そこで、本処理の動作の主体を生産計画立案支援システム１（以下、立案支援システム１と略記する場合がある）であるとして説明する。ここでは、製品モデル別の生産基本情報１２１を原単位１２１と呼ぶ。 FIG. 4 is a flowchart of the production planning support process. This process is realized by the microprocessor 101 of the production planning support system 1 executing the computer program 1031. Therefore, the main body of the operation of this process will be described as the production planning support system 1 (hereinafter, may be abbreviated as the planning support system 1). Here, the production basic information 121 for each product model is referred to as a basic unit 121.
　まず最初に、立案支援システム１の顧客要求情報取得部１３は、顧客要求情報を取得する（Ｓ１１）。立案支援システム１の選択部１６は、顧客要求情報に応じた原単位コードを設定する（Ｓ１２）。 First, the customer request information acquisition unit 13 of the planning support system 1 acquires customer request information (S11). The selection unit 16 of the planning support system 1 sets a basic unit code according to the customer request information (S12).
　例えば、ユーザは、顧客要求情報に含まれる製品の概略仕様や名称、発注元などの情報に基づいて、対象の製品に最も似ている製品モデルに対応する原単位１２１を選択することができる。そして、立案支援システム１は、選択された原単位１２１を特定する原単位コードを設定する。ユーザが立案支援システム１に原単位コードを入力することにより設定してもよい。後述の実施例のように、対象の製品の構成概要と製品構成情報１２３を比較することにより、対象製品に最も類似する製品モデルの原単位コードを自動的に設定することもできる。 For example, the user can select the basic unit 121 corresponding to the product model most similar to the target product based on the information such as the outline specification or name of the product included in the customer request information and the order source. Then, the planning support system 1 sets a base unit code that specifies the selected base unit 121. It may be set by the user inputting the basic unit code into the planning support system 1. As in the embodiment described later, the basic unit code of the product model most similar to the target product can be automatically set by comparing the configuration outline of the target product with the product configuration information 123.
　立案支援システム１の生産計画立案部１１は、所定のシミュレーション処理を実行することにより、生産計画を立案する（Ｓ１３）。立案支援システム１は、例えば図３でも述べたように、原単位１２１に定義された工程毎のリソース消費量に従って、各工程の日程別にリソース消費量を積み上げる（山積み処理）。そして、立案支援システム１は、山崩しが可能なリソース消費量については他の日程に分散させて再配置するなどして、生産計画を作成する。 The production plan drafting unit 11 of the drafting support system 1 drafts a production plan by executing a predetermined simulation process (S13). For example, as described in FIG. 3, the planning support system 1 accumulates the resource consumption according to the schedule of each process according to the resource consumption for each process defined in the basic unit 121 (stacking process). Then, the planning support system 1 creates a production plan by, for example, distributing the resource consumption for which the mountain collapse is possible to another schedule and reallocating it.
　立案支援システム１の情報提供部１７は、ステップＳ１３での処理結果をユーザインターフェース部１０５を介してユーザに提供する（Ｓ１４）。ユーザが提示された生産計画を修正した場合、その修正内容はユーザインターフェース部１０５を介して立案支援システム１に入力される（Ｓ１５）。 The information providing unit 17 of the planning support system 1 provides the processing result in step S13 to the user via the user interface unit 105 (S14). When the user corrects the presented production plan, the correction content is input to the planning support system 1 via the user interface unit 105 (S15).
　立案支援システム１の生産計画反映部１８は、ユーザが生産計画を承認したか監視しており（Ｓ１６）、ユーザにより承認された場合（Ｓ１６：ＹＥＳ）、ユーザに承認された生産計画を生産計画記憶部１９に登録させる（Ｓ１７）。 The production plan reflection unit 18 of the planning support system 1 monitors whether the user approves the production plan (S16), and when it is approved by the user (S16: YES), the production plan approved by the user is produced It is registered in the storage unit 19 (S17).
　ユーザが生産計画を修正した場合（Ｓ１６：ＮＯ）、立案支援システム１はステップＳ１３に戻り、再度シミュレーション処理を実行する。 When the user corrects the production plan (S16: NO), the planning support system 1 returns to step S13 and executes the simulation process again.
　いったん生産計画を作成した後に、顧客要求情報が変更される場合もある。立案支援システム１の顧客要求情報取得部１３は、顧客要求情報に変更があったことを確認すると（Ｓ１８：ＹＥＳ）、顧客要求情報のうち変更されたパラメータ（例えば、納期、製作数、仕様）を用いて（Ｓ１９）、再びシミュレーション処理を実行する（Ｓ１３）。 The customer requirement information may be changed once the production plan is created. When the customer request information acquisition unit 13 of the planning support system 1 confirms that there is a change in the customer request information (S18: YES), the changed parameters (for example, delivery date, number of productions, specifications) among the customer request information The simulation process is executed again (S13) using (S19).
　顧客要求情報に変更がない場合（Ｓ１８：ＮＯ）、本処理は終了する。なお、ステップＳ１８，Ｓ１９は別のフローチャートとして表示することができるが、ここでは説明の便宜上、ステップＳ１～Ｓ１７に続く処理として示している。 If there is no change in the customer request information (S18: NO), this process ends. Although steps S 18 and S 19 can be displayed as separate flowcharts, they are shown as processing following steps S 1 to S 17 for convenience of explanation.
　図５は、生産計画の立案方法の例を示す説明図である。日程計画情報記憶部１５は、顧客から受注した製番モデルごとに日程計画情報１５１を記憶している。生産計画立案部である工場シミュレータ１１は、工場シミュレータエンジン１１１へ所定の情報を入力することにより、生産計画を立案する。 FIG. 5 is an explanatory view showing an example of a method of planning a production plan. The schedule planning information storage unit 15 stores schedule planning information 151 for each serial number model ordered from the customer. The factory simulator 11, which is a production planning unit, prepares a production plan by inputting predetermined information to the factory simulator engine 111.
　日程計画情報記憶部１５に格納された日程計画情報１５１は、例えば、製番コード１５１１と、原単位コード１５１２と、製作数１５１３と、工程ごとの工程情報１５１４とを含む。工程情報１５１４は、その工程の終了予定日１５１４１と、その工程が実際に終了した実績日１５１４２と、計画作業標準時間（計画ＳＴ）１５１４３とを含む。 The schedule information 151 stored in the schedule information storage unit 15 includes, for example, a serial number code 1511, a basic unit code 1512, the number of productions 1513, and process information 1514 for each process. The process information 1514 includes a scheduled end date 15141 of the process, an actual date 15142 when the process is actually completed, and a planned operation standard time (plan ST) 15143.
　ここで、製番コード１５１１とは、受注した製品に付与される識別情報である。原単位コード１５１２とは、製番コード１５１１で特定される製品（受注製品）に類似する製品モデルに対応する原単位１２１を示す情報である。製作数１５１２とは、受注製品の数量、すなわち顧客の発注した製品の数である。工程情報１５１４は、受注製品の生産に関する工程の管理情報である。例えば、「設計」、「調達」、「製造」、「検査」、「出荷」といった工程ごとに、その工程の終了予定日１５１４１および終了実績日１５１４２が記録される。 Here, the serial number code 1511 is identification information given to the ordered product. The base unit code 1512 is information indicating the base unit 121 corresponding to a product model similar to the product (order-received product) specified by the serial number code 1511. The production number 1512 is the number of ordered products, that is, the number of products ordered by the customer. The process information 1514 is control information of the process related to the production of the ordered product. For example, for each process such as “design”, “procurement”, “manufacturing”, “inspection”, and “shipment”, the planned end date 15141 and the actual end date 15142 of the process are recorded.
　計画ＳＴ１５１４３には、例えば、原単位１２１では対応が難しい個別事情が受注製品に存在する場合に、その個別事情を考慮した作業時間を見積もることができるのであればその値が設定される。例えば、原単位１２１に対応する製品モデルの構成に比べて特殊部品が追加されたとか、特殊な加工が追加されたなどのように、生産工程の作業時間に影響を与える個別事情がある場合、ユーザは、その個別事情を加味した作業時間を計画ＳＴ１５１４３へ設定する。したがって、計画ＳＴ１５１４３に設定される値は、後述する原単位１２１の消費リソース１２１４１に含まれる標準作業時間（ＳＴ）とは異なる。 In the plan ST15143, for example, in the case where there is an individual circumstance where it is difficult to cope with the basic unit 121 in the order-received product, the value is set if an operation time taking into consideration the individual circumstance can be estimated. For example, when there are individual circumstances that affect the working time of the production process, such as when special parts are added or special processing is added as compared to the configuration of the product model corresponding to the basic unit 121, The user sets the work time in consideration of the individual circumstances in the plan ST15143. Therefore, the value set in the plan ST15143 is different from the standard work time (ST) included in the consumption resource 12141 of the basic unit 121 described later.
　記憶部１２に格納された原単位１２１（原単位情報１２１）は、例えば、原単位コード１２１１と、基準製作数１２１２と、工程順序１２１３と、工程ごとの工程情報１２１４とを含む。工程情報１２１４は、その工程で使用する（消費する）各リソース１２１４１の消費量と、標準リードタイム１２１４２と、リードタイム係数条件１２１４３とを含んでいる。 The basic unit 121 (basic unit information 121) stored in the storage unit 12 includes, for example, a basic unit code 1211, a reference production number 1212, a process order 1213, and process information 1214 for each process. The process information 1214 includes the consumption amount of each resource 12141 used (consumed) in the process, the standard lead time 12142, and the lead time coefficient condition 12143.
　原単位１２１とは、上述のように、製品モデルごとに予め作成された情報であり、一つの製品モデル（一つの原単位）に、一つまたは複数の製品が対応づけられる。既存の製品モデルのいずれとも似ていない製品を受注した場合は、新たな製品モデル（原単位）を定義することができる。 The basic unit 121 is information previously created for each product model as described above, and one or more products are associated with one product model (one basic unit). If an order is received for a product that is not similar to any of the existing product models, a new product model (base unit) can be defined.
　原単位コード１２１１とは、原単位１２１を特定する識別情報である。基準製作数１２１２とは、基準の製作数である。基準製作数は通常、１個であるが、複数個一セットで製造する製品の場合は、「１」以外の値が設定される。工程順序１２１３とは、原単位１２１で特定される製品を生産するための複数工程の順序を示す。工程情報１２１４は、工程ごとに用意される。消費リソース１２１４１は、その工程で使用するリソースの消費量である。ここでは、作業時間（ＳＴ）を例示する。標準リードタイム１２１４２は、その工程の標準的なリードタイムである。リード係数条件１２１４３は、標準リードタイムを計画ＳＴ１５１４３の値で補正する場合に使用する係数である。 The base unit code 1211 is identification information for specifying the base unit 121. The reference production number 1212 is the number of reference productions. The standard production number is usually one, but in the case of a product manufactured by one set, a value other than “1” is set. The process order 1213 indicates the order of a plurality of processes for producing the product specified by the basic unit 121. Process information 1214 is prepared for each process. The consumption resource 12141 is the consumption of resources used in the process. Here, the working time (ST) is illustrated. The standard lead time 12142 is a standard lead time of the process. The read coefficient condition 12143 is a coefficient used when correcting the standard lead time with the value of the plan ST15143.
　記憶部１２には、リソースごとの生産能力情報１２２も記憶されている。生産能力情報１２２は、例えば、最大消費量である能力値（上限値）１２２１と、リソース消費タイプ１２２２とを含む。リソース消費タイプ１２２２とは、例えば、上述した「全日占有型」、「全日按分型」、「前詰め型」、「初日消費型」である。すなわち、本実施例では、各工程で使用される各リソースについて、その性質に応じた消費タイプを定義できるようになっている。 The storage unit 12 also stores production capacity information 122 for each resource. The production capacity information 122 includes, for example, a capacity value (upper limit value) 1221 which is a maximum consumption amount, and a resource consumption type 1222. The resource consumption type 1222 is, for example, the “all day exclusive type”, the “all day allotment type”, the “front-loading type”, and the “first day consumption type” described above. That is, in this embodiment, consumption types can be defined according to the nature of each resource used in each process.
　工場シミュレータ１１による作業時間（ＳＴ）の選択について説明する。工場シミュレータ１１は、日程計画情報１５１に計画ＳＴ１５１４３が設定されている場合、計画ＳＴを使用する。計画ＳＴは、生産計画立案の対象である製品とその製品に類似する製品モデルとの間の差異を反映する値であるため、計画ＳＴを用いて生産計画を立案する方が精度が向上するためである。 The selection of the working time (ST) by the factory simulator 11 will be described. When the plan ST15143 is set in the schedule information 151, the factory simulator 11 uses the plan ST. The plan ST is a value that reflects the difference between the product targeted for production planning and a product model similar to the product, so it is more accurate to plan the production plan using the plan ST. It is.
　これに対し、工場シミュレータ１１は、日程計画情報１５１に計画ＳＴ１５１４３が設定されていない場合、原単位１２１に定義されている作業時間（ＳＴ）を用いる。つまり、特殊な仕様や加工についての作業時間の見積もりができない場合であっても、工場シミュレータ１１は、原単位１２１を用いることで、ある程度の精度を持った生産計画を生成できる。 On the other hand, when the plan ST15143 is not set in the schedule information 151, the factory simulator 11 uses the working time (ST) defined in the basic unit 121. That is, even if it is not possible to estimate the working time for special specifications or processing, the factory simulator 11 can generate a production plan with a certain degree of accuracy by using the basic unit 121.
　リードタイム（ＬＴ）の選択について説明する。計画ＳＴ１５１４３が設定されている場合、計画ＳＴ１５１４３の値と標準リードタイム１２１４２の値とリード係数条件１２１４３とに基づいて、生産計画の立案に使用するリードタイムを算出する。リードタイム係数条件１２１４３には、作業時間（ＳＴ）の値に応じて係数が設定されている。 The selection of the lead time (LT) will be described. When the plan ST15143 is set, the lead time to be used for drawing up the production plan is calculated based on the value of the plan ST15143, the value of the standard lead time 12142 and the lead coefficient condition 12143. In the lead time coefficient condition 12143, a coefficient is set according to the value of the working time (ST).
　例えば、標準リードタイムが１日であり、計画ＳＴが３０時間であり、係数は、作業時間が１時間から１０時間までは「１」、作業時間が１０時間を超えて３０時間までは「２」であるとする。 For example, the standard lead time is 1 day, the plan ST is 30 hours, and the factor is “1” for working hours from 1 hour to 10 hours, “2” for working hours exceeding 10 hours and 30 hours It is assumed that
　工場シミュレータ１１は、計画ＳＴが存在する場合は計画ＳＴを採用する。計画ＳＴの値が３０時間なので、係数は「２」となる。工場シミュレータ１１は、標準リードタイムの「１日」に係数「２」を乗じて、リードタイム「２日」を得る。なお、計画ＳＴ１５１４３が設定されていない場合、工場シミュレータ１１は、標準リードタイム１２１４２の値を採用する。 When the plan ST exists, the factory simulator 11 adopts the plan ST. Since the value of the planned ST is 30 hours, the coefficient is "2". The factory simulator 11 obtains the lead time "2 days" by multiplying the standard lead time "1 day" by the coefficient "2". When the plan ST15143 is not set, the factory simulator 11 adopts the value of the standard lead time 12142.
　図６は、生産計画の立案対象である製品について既存の原単位１２１の中から最も類似すると考えられる製品モデルの原単位１２１を設定する画面Ｇ１の例である。 FIG. 6 is an example of a screen G1 for setting a basic unit 121 of a product model that is considered to be most similar among existing basic units 121 for a product for which a production plan is to be formulated.
　原単位コード設定画面Ｇ１は、例えば、案件検索条件部ＧＰ１１と、検索結果表示部ＧＰ１２と、検索ボタンＢ１１と、登録ボタンＢ１２とを備える。 The basic unit code setting screen G1 includes, for example, a case search condition unit GP11, a search result display unit GP12, a search button B11, and a registration button B12.
　ユーザは、例えば、注文番号、製番、製番ステータス（完了、未完了など）といった検索条件を指定することにより、原単位コードを設定したい製品（生産計画の立案対象製品）を検索することができる。 The user may search for a product (production planning target product) for which the base unit code is to be set by specifying a search condition such as, for example, an order number, a machine number, or a machine number status (completed, incomplete, etc.) it can.
　検索結果表示部ＧＰ１２には、検索条件に該当する製品について、例えば、連番、チェック欄（選択欄）、注文番号、製番、品名、製作数、製番ステータス、原単位コードなどが一覧形式で表示される。ユーザが原単位コード欄を選択すると、図６の下側に示すように、原単位コードを選択するための画面ＧＰ１３が出現する。 The search result display section GP12 displays, for example, serial numbers, check fields (selection fields), order numbers, serial numbers, article names, production numbers, serial numbers, basic unit codes etc. Is displayed. When the user selects the basic unit code field, a screen GP13 for selecting a basic unit code appears as shown in the lower side of FIG.
　原単位コード選択画面ＧＰ１３は、例えば、原単位コードと、製品名称とを対応づけて表示する。なお、製品名称は、例えば、製品の種類、概略仕様、仕向先などの情報が含まれるようにして登録されていると使い勝手がよい。ユーザは、製品名称に基づいて、生産計画の立案対象の製品に最も近いと思われる原単位コードを選択する。 The base unit code selection screen GP13 displays, for example, the base unit code and the product name in association with each other. In addition, it is convenient if the product name is registered, for example, so as to include information such as the type of product, the rough specification, the destination, and the like. The user selects, based on the product name, a unit code which is considered closest to the product for which the production plan is to be formulated.
　図７は、生産計画の立案対象とする製品を選択する画面Ｇ２の例である。シミュレーション対象選択画面Ｇ２は、例えば、案件検索条件ＧＰ２１と、検索結果表示部ＧＰ２２と、検索ボタンＢ２１と、シミュレーション開始ボタンＢ２２とを備える。 FIG. 7 is an example of a screen G2 for selecting a product to be a production planning target. The simulation target selection screen G2 includes, for example, a case search condition GP21, a search result display unit GP22, a search button B21, and a simulation start button B22.
　ユーザは、注文番号や製番などの検索条件を指定して検索させ、その検索結果の中から生産計画の立案対象となる製品を少なくとも一つ選択する。生産期間が重なる複数の製品の全てを一括して選択することもできる。ユーザが、対象の製品または製品群を選択してから開始ボタンＢ２２を操作すると、シミュレーション開始画面Ｇ３へ遷移する。 The user designates a search condition such as an order number or a production number and makes a search, and selects at least one product which is a target of a production plan from among the search results. It is also possible to select all of a plurality of products whose production periods overlap with one another. When the user operates the start button B22 after selecting the target product or product group, the transition to the simulation start screen G3 is made.
　図８は、シミュレーション開始画面Ｇ３の例である。シミュレーション開始画面Ｇ３は、例えば、シミュレーションモード選択部ＧＰ３１と、シミュレーション対象製品表示部ＧＰ３２と、シミュレーション開始ボタンＢ３１とを備える。 FIG. 8 is an example of the simulation start screen G3. The simulation start screen G3 includes, for example, a simulation mode selection unit GP31, a simulation target product display unit GP32, and a simulation start button B31.
　シミュレーションモード選択部ＧＰ３１は、例えば、スケジューリングモード選択部ＧＰ３１１と、山崩し処理設定部ＧＰ３１２と、シミュレーション順序指定部ＧＰ３１３とを備える。 The simulation mode selection unit GP31 includes, for example, a scheduling mode selection unit GP311, a collapse processing setting unit GP312, and a simulation order designation unit GP313.
　スケジューリングモード選択部ＧＰ３１１では、例えば「日程計画通り」、「全タスクフォワード」、「全タスクバックワード」、「フォワード＆バックワード（ハイブリッド）」の中からいずれか一つ選択可能である。「日程計画通り」とは、既に設定された日程に従ってシミュレーションすることを意味する。タスクとは工程を意味する。他のモードについては、図３で述べた通りである。 In the scheduling mode selection unit GP311, for example, one of “scheduled according to schedule”, “all task forward”, “all task backward”, and “forward & backward (hybrid)” can be selected. "As scheduled" means to simulate according to a preset schedule. A task means a process. The other modes are as described in FIG.
　山崩し処理設定部ＧＰ３１２は、山崩し処理（負荷分散処理）を実施するか否かを設定する。山崩し処理あり（図中、山崩しあり）に設定された場合、工場シミュレータ１１は、各工程の各単位期間において、各リソースの消費量（生産負荷、あるいはリソース負荷）が能力値（上限値）以内となるように、工程の計画を立案する。これに対し、山崩し処理なしに設定された場合、工場シミュレータ１１は、各リソースの能力を考慮せずに工程の計画を立案する。すなわち、工場シミュレータ１１は、各リソースの能力が無制限であるとみなしてシミュレーションを実施するため、リードタイムが最小となる工程計画を立案することができる。ユーザは、山崩し処理なしでのシミュレーション結果結果から、ボトルネックの有無などを確認することができる。ユーザは、能力値を超えた箇所については、例えば、作業者グループの人数を調整したり、設備を追加したりすることにより、ボトルネックを解消することができる。 The landslide processing setting unit GP <b> 312 sets whether or not to carry out landslide processing (load distribution processing). When the landslide processing is set (in the figure, with the landslide), the factory simulator 11 sets the consumption value (production load or resource load) of each resource to the capacity value (upper limit value) in each unit period of each process. Create a process plan so that it will be within On the other hand, when it is set without the mountain collapse processing, the factory simulator 11 draws up a process plan without considering the capacity of each resource. That is, since the factory simulator 11 performs the simulation on the assumption that the capacity of each resource is unlimited, it is possible to make a process plan with the smallest lead time. The user can confirm the presence or absence of a bottleneck or the like from the simulation result without the landslide processing. The user can eliminate the bottleneck, for example, by adjusting the number of workers in the worker group or adding equipment at a place where the capability value is exceeded.
　シミュレーション順序指定部ＧＰ３１３は、シミュレーション順序を選択する。例えば、注文番号、製番、製作数などの観点からシミュレーション順序を指定できる。シミュレーション順序指定部ＧＰ３１３で指定したシミュレーション順序と、スケジューリングモード選択部ＧＰ３１１で選択されたスケジューリングモードとにより、シミュレーション対象の優先順序が決定される。 The simulation order designation unit GP313 selects a simulation order. For example, the simulation order can be specified in terms of order number, production number, production number, and the like. Based on the simulation order specified by the simulation order specification unit GP313 and the scheduling mode selected by the scheduling mode selection unit GP311, the priority order of the simulation target is determined.
　シミュレーション対象製品表示部ＧＰ３２において、ユーザは、抽出された製品の中からシミュレーション処理の対象外とする製品を選択することができる。 In the simulation target product display unit GP32, the user can select a product to be excluded from the simulation processing from the extracted products.
　図９は、シミュレーション結果画面Ｇ４の例である。シミュレーション結果画面Ｇ４は、例えば、シミュレーションモード表示部ＧＰ４１と、表示方法表示部ＧＰ４２と、ガントチャートＧＰ４３と、生産負荷の山積みグラフＧＰ４４と、日程計画反映ボタンＢ４１とを備える。 FIG. 9 is an example of the simulation result screen G4. The simulation result screen G4 includes, for example, a simulation mode display unit GP41, a display method display unit GP42, a Gantt chart GP43, a pile graph GP44 of a production load, and a schedule planning reflection button B41.
　シミュレーションモード表示部ＧＰ４１には、シミュレーション処理に使用したパラメータ（スケジューリングモードなど）が表示される。表示方法表示部ＧＰ４２は、ガントチャートＧＰ４３に表示する項目の順序を表示する。例えば、注文番号、製番、起点タスクの日付について、昇順または降順のいずれかで表示させることができる。さらに、表示方法表示部ＧＰ４２は、ガントチャートＧＰ４３、山積みグラフＧＰ４４、図示せぬ期限情報のうちいずれを表示させるかを選択するためのボタンを備えてもよい。図９では、ガントチャートＧＰ４３と山積みグラフＧＰ４４の両方を一つの画面Ｇ４に表示させるかのように示すが、いずれか選択された方を表示させてもよい。 The simulation mode display unit GP41 displays parameters (such as scheduling mode) used for the simulation process. The display method display unit GP42 displays the order of items displayed on the Gantt chart GP43. For example, the order number, the serial number, and the date of the starting task can be displayed in ascending or descending order. Furthermore, the display method display unit GP42 may include a button for selecting which of the Gantt chart GP43, the pileup graph GP44, and the time limit information (not shown) to be displayed. Although FIG. 9 shows that both the Gantt chart GP43 and the pileup graph GP44 are displayed on one screen G4, any one selected may be displayed.
　山積みグラフＧＰ４４では、各工程のリソースごとにリソース消費量（生産負荷）を山積みしたグラフを表示することができる。山積みグラフＧＰ４４において、符号Ｔｈ１～Ｔｈ３は、能力値を示す閾値である。 The pileup graph GP44 can display a graph in which resource consumption (production load) is piled up for each resource of each process. In the heap graph GP44, symbols Th1 to Th3 are threshold values indicating capability values.
　このように構成される本実施例によれば、製品モデル別の生産基本情報である原単位１２１を用意しておき、対象製品に近い製品モデルの原単位１２１に基づいて、生産計画を立案することができるため、部品構成表を作成する手間がかからず、効率的に生産計画を作成することができる。 According to this embodiment configured as described above, the basic unit 121 which is production basic information for each product model is prepared, and a production plan is formulated based on the basic unit 121 of the product model close to the target product. As a result, it is possible to efficiently create a production plan without the trouble of creating a component configuration table.
　さらに本実施例によれば、事前に見積もり可能なリソース消費量については、計画値として設定することができるため、製品モデルとの乖離が大きい製品の場合であっても生産計画を作成することができ、使い勝手が高い。 Furthermore, according to the present embodiment, the resource consumption that can be estimated in advance can be set as a planned value, so that a production plan can be created even in the case of a product with a large deviation from the product model. Yes, it is easy to use.
　図１０および図１１を用いて第２実施例を説明する。本実施例を含む以下の各実施例は、第１実施例の変形例に相当するため、第１実施例との差異を中心に述べる。本実施例では、作業時間（ＳＴ）を自動学習する。 A second embodiment will be described with reference to FIGS. 10 and 11. Each of the following embodiments including the present embodiment corresponds to a modification of the first embodiment, and therefore, differences from the first embodiment will be mainly described. In the present embodiment, the working time (ST) is automatically learned.
　図１０は、生産計画の立案方法の例を示す説明図である。図１０と図５を比較すると、本実施例では、作業時間自動修正部２１と、作業時間自動設定部２３とを備える。作業時間自動修正部２１は、図１における修正部２１の一例である。作業時間自動設定部２３は、図１における自動設定部２３の一例である。 FIG. 10 is an explanatory view showing an example of a method of planning a production plan. Comparing FIG. 10 with FIG. 5, in the present embodiment, the working time automatic correction unit 21 and the working time automatic setting unit 23 are provided. The working time automatic correction unit 21 is an example of the correction unit 21 in FIG. The working time automatic setting unit 23 is an example of the automatic setting unit 23 in FIG. 1.
　図１１は、実績値データベース１２４の例を示す。実績値データベース１２４は、例えば、原単位コードと、製品名称と、工程名と、実績作業時間とを対応づけて管理することができる。 FIG. 11 shows an example of the actual value database 124. The actual value database 124 can manage, for example, the basic unit code, the product name, the process name, and the actual operation time in association with one another.
　作業時間自動修正部２１は、作業時間の実績値を管理する実績値データベース１２４に基づいて、原単位１２１の消費リソース１２１４１内の作業時間を修正する。作業時間自動修正部２１は、例えば、実績値データベース１２４に記憶された実績値の所定の実績値を取り出して統計処理することにより、原単位１２１内の作業時間を自動的に修正することができる。すなわち、本実施例では、原単位１２１の持つ情報のうち所定の一部について自動学習する機能を追加している。 The working time automatic correction unit 21 corrects the working time in the consumption resource 12141 of the basic unit 121 based on the actual value database 124 that manages the actual value of the working time. The working time automatic correction unit 21 can automatically correct the working time in the basic unit 121 by, for example, extracting and statistically processing a predetermined actual value of the actual values stored in the actual value database 124. . That is, in the present embodiment, a function of automatically learning a predetermined part of the information held by the basic unit 121 is added.
　作業時間自動設定部２３は、製品構成情報１２３と実績値データベース１２４とに基づいて、日程計画情報１５１内の計画ＳＴ１５１４３の値を算出し、設定する。過去に製造された製品構成と対象製品の構成との比較結果に応じて、実績値データベース１２４から読出した実績値を補正することにより、計画ＳＴ１５１４３の値を自動的に設定することができる。なお、ユーザは、自動的に設定された計画ＳＴ１５１４３の値を手動で変更することもできる。 The working time automatic setting unit 23 calculates and sets the value of the plan ST15143 in the schedule plan information 151 based on the product configuration information 123 and the actual value database 124. By correcting the actual value read out from actual value database 124 according to the comparison result of the product configuration manufactured in the past and the configuration of the target product, the value of plan ST15143 can be set automatically. Note that the user can also manually change the value of the plan ST15143 set automatically.
　このように構成される本実施例も第１実施例と同様の作用効果を奏する。さらに本実施例によれば、原単位１２１内のリソース消費量（作業時間ＳＴ）を自動的に修正（学習）することができ、さらに、計画ＳＴ１５１４３の値も自動的に設定することができるため、ユーザの使い勝手が向上する。 The present embodiment configured in this way also achieves the same effects as the first embodiment. Furthermore, according to the present embodiment, the resource consumption (working time ST) in the basic unit 121 can be automatically corrected (learned), and furthermore, the value of the plan ST15143 can also be set automatically. , User-friendliness is improved.
　図１２を用いて第３実施例を説明する。本実施例では、新たな原単位１２１を自動的に設定することができると共に、対象製品に適した原単位コードを自動的に設定することができる。 A third embodiment will be described with reference to FIG. In this embodiment, a new base unit 121 can be set automatically, and a base unit code suitable for the target product can be set automatically.
　図１２は、生産計画の立案方法の例を示す説明図である。図１２と図１０とを比較すると、本実施例では、原単位１２１を自動的に生成する原単位自動生成部２２と、日程計画情報１５１に原単位１２１を自動的に設定する原単位コード自動設定部１６ａとを備えている。 FIG. 12 is an explanatory view showing an example of a method of planning a production plan. Comparing FIG. 12 with FIG. 10, in this embodiment, the base unit automatic generation unit 22 automatically generates the base unit 121, and the base unit code automatic setting the base unit 121 automatically in the schedule plan information 151. And a setting unit 16a.
　原単位自動生成部２２は、図１におけるモデル別生産基本情報自動生成部２２の一例である。原単位コード自動設定部１６ａは、図１における選択部１６の一例である。 The basic unit automatic generation unit 22 is an example of the model-based production basic information automatic generation unit 22 in FIG. The base unit code automatic setting unit 16a is an example of the selection unit 16 in FIG.
　原単位自動生成部２２は、例えば、作業時間自動修正部２１での処理結果に基づいて、新たな原単位１２１を生成するか否かを判定する。原単位自動生成部２２は、新たな原単位１２１を生成すべきと判定すると、元となる原単位１２１の少なくとも一部を書き換えることにより新たな原単位１２１を生成する。新たに生成された原単位１２１は、記憶部１２に記憶される。 The base unit automatic generation unit 22 determines whether to generate a new base unit 121 based on the processing result of the working time automatic correction unit 21, for example. When it is determined that the new basic unit 121 should be generated, the basic unit automatic generation unit 22 generates a new basic unit 121 by rewriting at least a part of the original unit 121. The newly generated basic unit 121 is stored in the storage unit 12.
　例えば、作業時間自動修正部２１が或る原単位の作業時間についてその実績値を統計処理した結果、異なる作業時間パターンを発見する場合が考えられる。この場合、一方の作業時間パターンに即して生成された原単位では、他の作業時間パターンは異質なものとなり、生産計画の精度に影響を与える可能性がある。そこで、本実施例では、例えば、リソース消費量（作業時間）のパターンの相違に基づいて、新たな原単位１２１を自動的に生成する。 For example, there may be a case where different working time patterns are found as a result of the working time automatic correction unit 21 statistically processing the actual value of the working time of a certain basic unit. In this case, in the basic unit generated according to one of the work time patterns, the other work time patterns become heterogeneous, which may affect the accuracy of the production plan. Therefore, in the present embodiment, for example, a new basic unit 121 is automatically generated based on the difference in the pattern of resource consumption (working time).
　原単位コード自動設定部１６ａは、対象製品の概要構成と製品構成情報１２３とを比較することにより、対象製品に最も近いと判定される製品モデルの原単位１２１を抽出し、対象製品の日程計画情報１５１に設定する。 The base unit code automatic setting unit 16a extracts the base unit 121 of the product model determined to be closest to the target product by comparing the outline configuration of the target product with the product configuration information 123, and schedules the target product. The information 151 is set.
　このように構成される本実施例も第１、第２実施例と同様の作用効果を奏する。さらに本実施例によれば、より一層使い勝手を向上することができる。 The present embodiment configured in this way also exhibits the same effects as the first and second embodiments. Furthermore, according to the present embodiment, the usability can be further improved.
