Abstract: In the process of digital transformation, How to solve production scheduling problem,Researchers very attention. Machine failure is mixed flow shop to happen problem in production scheduling. Therefore,it is necessary to find a way to quickly solve the rescheduling of faulty machines. To this end, several main factors are needed to be considered, which are processing time the logistics loading and unloading time and the limitation of the layout of production equipment. Based on these considerations, a rescheduling method combining multiple rescheduling is proposed. Firstly, a dual-objective mathematical model is established, with the NSGA-II algorithm implanted into the system to solve the initial scheduling scheme. The algorithm uses heuristic rules and randomization to generate the initial solution and uses the simulation method to evaluate the scheduling scheme. Secondly, a variety of rescheduling methods are integrated, and the rescheduling method verified by equipment failure simulation and experimental verification heuristic rules can be used as part of the initial solution, which can greatly improve the search efficiency of the algorithm. The rescheduling method studied can effectively deal with machine failures in hybrid flow workshops and is of great significance.
