Open Order Rescheduling in Job Shops with Demand Uncertainty: A Simulation Study
通过8台机器作业车间的仿真实验，研究了四种订单更新策略，发现开放订单重调度仅在宽松交货期下有益，且能改善库存绩效，尤其当交货期提前时。
ABSTRACT This paper addresses the problem of open order rescheduling in a job shop. Results are reported of experiments conducted in a simulation model of an 8‐machine job shop. Four different order updating policies are examined. The due‐date process is modeled to include several realistic features about the pattern of due‐date variability. These features are parameterized and tested at several levels. Tardiness results indicate that open order rescheduling is beneficial only when allowances are loosely set. The results indicate that inventory performance is improved by order rescheduling, particularly in cases when due dates are revised to earlier times than originally forecast.
