Optimum on technological process based on genetic algorithms

In order to solve some scheduling problems about multi-mission, multi-restriction and re-entrant multi-machine, model of timing Petri net is built, combination of technique on discrete event simulation and simulation algorithms based on dual code is proposed by using genetic algorithms,the optimized scheduling planning about technological process is computed. Maintain technological process of BJ2020 vehicle is optimized by using this method, simulation experimental result shows that maintain efficiency of vehicle can be improved by using this method, and it can be used in technological process in other areas.
