The Equipment Scheduling and Assignment Problem in the Overhaul Industry

In this article, equipment overhaul is considered in a multi-stage flow shop scheduling problem. problem, the equipments are disassembled first stage, and repairs done on parallel workshops second assembly operation third stage. Considering three-stage with machines stages new industry. The sequence of processing determined as well allocation should be such way that total completion time jobs minimized. Unlike most articles, not same all changes use decoding. For next innovation: order to solve mathematical model presented. Two improved algorithms, Genetic Algorithms (GA) Particle Swarm Optimization (PSO) presented problem large dimensions. By using shortest (SPT) heuristic, these two algorithm have been Hybrid GA (HGA) PSO (HPSO) algorithms achieve better results current conditions, parameters setting by one-way analysis variance (ANOVA). Finally, it possible improve performance applying discussed issues.
