Intelligent scheduling technology plays a very important role in the production process of manufacturing enterprises. In order to solve the global optimization problem of wafer manufacturing scheduling system, firstly this paper considers the constraint relationship between the equipment of wafer manufacturing system. At the same time, the overall scheduling system is divided into three stages: storage stage, consolidation stage and processing stage. The time cost is analyzed and the mathematical model aiming at minimizing the time cost is established. Secondly, multi-layer coding genetic algorithm is used to solve the model. Finally, the effectiveness of the model is verified by MATLAB simulation and solution based on the data of a wafer processing and manufacturing enterprise.
