英文摘要：

This paper proposes a two-dimension encoding approach based on the job operation sequence and uses Evolutionary Strategy（ES） algorithm to solve the Job-shop Scheduling Problem（JSP）.A kind of recombination operation based on three-point crossover and interchange is used to generate the offspring individuals,and a kind of mutation operation is designed that some gene in the encoding is stochastically generated.Experimental results show that evolutionary strategy algorithm can effectively optimize the JSP and has better performance than genetic algorithm and hybrid particle swarm optimization algorithm.ES algorithm based on three-point crossover and interchange recombination operation has better performance than the recombination operation based on two-point crossover and interchange and the recombination operation based on four-point crossover and interchange.
