PRODUCTION PLANNING SYSTEM AND PRODUCTION PLANNING METHOD

To develop a production plan that reduces an environmental load such as power consumption while adhering to a required deadline or the like even when various type mixed production is performed.SOLUTION: A production planning system comprises a calculation unit and a storage unit. The storage unit holds production planning information. The production planning information includes a model of each product to be produced, a required deadline for each process of each product, and an expected completion timing of each process of each product. The calculation unit generates an operation plan for a facility that performs each process for each product, based on the production planning information, so that the required deadline for each process for each product is met, and changes the operation plan based on an index for indicating a reduction in power consumption of the facility so that the required deadline for each process of each product is met and a period in which the facility is not in operation is included.SELECTED DRAWING: Figure 1 【課題】多品種混流生産が行われる場合にも、要求期限等を遵守しつつ、消費電力等の環境負荷を低減する生産計画を立案する。【解決手段】生産計画システムであって、演算部と、記憶部と、を備え、記憶部は、生産計画情報を保持し、生産計画情報は、生産される各製品の型式と、各製品の各工程の要求期限と、各製品の各工程の完成予定時期と、を含み、演算部は、生産計画情報に基づいて、各製品の各工程の要求期限が満たされるように、各製品の各工程を行う設備の稼働計画を生成し、設備の消費電力の削減を示す指標に基づいて、各製品の各工程の要求期限が満たされ、かつ、設備が稼働しない期間を含むように、稼働計画を変更する。【選択図】図１
