摘　　要：针对车间生产重调度问题,结合离散车间制造过程透明化的现状,提出了异常事件驱动的离散制造车间重调度决策方法。在物联网驱动的离散制造车间环境下,利用复杂事件处理技术分析并处理制造过程的实时信息。通过定义重调度的判定方案、驱动机制和性能评价指标,提出了面向成本的离散车间重调度决策方法,并借助模拟退火遗传算法对最优重调度方案进行求解。通过对经过事件处理后获得的离散车间异常事件的案例分析,验证了该重调度决策方法的有效性。To solve the problem of rescheduling of workshop production process, combined with the present situation of transparent manufacturing process in discrete workshop, a decision method of rescheduling and an event processing in discrete workshop driven by the abnormal events are proposed. In the lOT driven discrete manufacturing workshop environment, the complex event processing technology is applied to analyze and deal with the real-time information on manufacturing processes. On this basis, by defining the driven mechanism, the decision scheme and the performance evaluation index of rescheduling, the decision method of rescheduling in discrete workshop facing the costing is put forward; and with the help of simulated annealing and genetic algorithm, the optimal scheduling scheme is figured out. The effectiveness of the rescheduling decision method is verified by the case study of the abnormal events in the discrete workshop, which is obtained after the event processing.
