摘要

A unified optimization model was proposed for mixed batch/continuous process scheduling problems. The Two Stage Random Ratio method was introduced to encode the job sequence, and the production velocity was stabilized by fluctuation adjustment The makespan criterion was amended by introducing minimum machine halt criterion to refine the criteria system of solutions. The Artificial Bees Colony algorithm was used to search the optimum solution and scheduling sequence was acquired by reverse decoding. The proposed algorithm was applied in a caustic soda production process of chemical industry, and compared with the results in literatures, which confirmed the feasibility of proposed algorithm.
