Dynamical niche sets-based cooperative evolutionary algorithm for job shop scheduling
Genbao Zhang · Journal of Chongqing University. English Edition · 2011
Job shop scheduling is an important part of manufacturing process.Pre-mature,local optimal solution or low convergence rate of Genetic Algorithm may come across in solving scheduling problem in multi-Job shop.To avoid those unhealthy tendencies,this paper introduced the Dynamical Niche Sets-based Cooperative Evolutionary Algorithm model.In the Algorithm,Process-based chromosome encoding method was used;the crossover operator and mutation operator were designed to adjust operation sequences and choose process routes.The cooperative scheduling problem in multi-Job shop was solved using dynamical niche sets technology and multi-population cooperative evolution method.The Experiment result shows the proposed method has good advantages.
