Abstract:

A hybrid discrete state transition algorithm (HDSTA) is designed to solve the energy-efficient no-wait flow shop scheduling problem (EENWFSP) minimizing makespan and total energy consumption. According to the characteristics of the problem, the coding method of job sequence and speed matrix is designed, and the heuristic algorithm is used to obtain the high-quality initial solution. According to the properties of EENWFSP, solving and allocating four discrete operators. The swap, shift and symmetry operators are embedded in secondary state transition are used for job sequence optimization, and the substitute operators are used for machine speed optimization. The speed substitute strategy based on critical path is embedded in the substitute operators. An improved destructive reconstruction operation is designed to further improve the quality of Pareto solution. Experimental results of four algorithms on test cases show that HDSTA has strong advantages in solving EENWFSP.
