Optimization of the batches processing modes and resource scheduling for mixed-model manufacturing system of multi-variety and small-batch considering handling time

This paper, based on the consideration of the handling time, aimed to conduct a study on the optimization of the batches processing modes and resource scheduling for the mixed-model manufacturing system. The time models of the processing and handling for batch parts were established in order to obtain the solutions to the makespan and optimize the handling frequency. In this foundation, a principle was analyzed for determining the optimum processing sequencing. Besides, an optimization algorithm of the mutual-aid teams was also designed to schedule the handling equipments needed by the optimum processing sequencing. The results show that the study in this thesis can provide effective solutions to the makespan of batch parts, optimize the handling time and frequency, acquire the optimum processing sequencing, and schedule the resources of the handling equipments sensibly.
