Abstract: Most scheduling problems assume that the job is produced in a single or batch mode, while in the real manufacturing environment, the job can be split. In order to solve the problem of splitting the job and making a reasonable scheduling scheme when considering the mold constraint, an optimized objective model of lot streaming in parallel machine scheduling with mold constraint is built for minimizing the makespan. Meanwhile, a mixed differential evolution genetic algorithm (DEGA), based on combination of genetic algorithm and differential evolution, is proposed to solve this model. It can implement parallel optimization of job splitting and scheduling problems. Numerical experiments and a realistic case are performed by DEGA, and the results indicate that the model and mixed algorithm are efficient and feasible.
