納期遅れジョブ数最小化を目的としたシミュレーションベースのスケジュ-ル作成法

抄録

For minimizing the number of tardy jobs in a make-to-order production, a production scheduling method associated with Backward / Forward Hybrid Simulation (BFHS) is proposed. The significance of tardy job minimization in production management is first discussed. Then discussion centers on a production scheduling method which introduces two parameters, job grouping parameter and slack time adjustment parameter, in order to adjust job priorities in each dispatching point in the simulation process. The effectiveness is shown not only on a simple job shop model, but also on an actually working system.
