In this paper,an improved genetic algorithm is proposed to solve the mutli-objective job-shop scheduling problem(JSP).This hybrid genetic algorithm approach is a method of combining the traditional genetic algorithm with the particle swarm optimization(SPO),in which multi-objective genetic algorithm is adopted to get primary optimized results,treated as initial particles of the SPO.It is then applied to the enhancing of local searching and speed convergence,to solve traditional genetic algorithm's problems ...
