Abstract: 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 IOT 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.
