Due Date Assignment Method based on LOMC

摘要

In this paper a due date assignment (DDA) method based on LOMC control has been presented, which is named LDDA. As a capacity-driven approach, LDDA considered the influence exerted by LOMC mechanism and determined the possible release date of an arriving order, according to the workload information of the order and current available capacity of the manufacturing system. Therefore, the due date of the order could be obtained. Meanwhile, LOMC mechanism and the dispatching rule were adjusted to comply with the plan arranged by LDDA. Finally, simulation experiments were carried out to compare four controlling programs, containing DDA methods of LDDA, TWK and RTP. Simulation results show that LDDA outperformed TWK remarkably when LOMC was applied. Second, it concludes that when ORR is applied, the DDA method should consider the influence of ORR on the order's progress, otherwise it will depreciate the delivery performance. Third, it confirms ORR is not fit for those companies faced with fierce lead time competition, though helps to realize better performance on other aspects.
