A Multi-objective Production Scheduling Case Study Solved by Genetic Algorithms
The scheduling problem associated with the manufacturing process is very complex, since this involves several constraints and objectives. These constraints are related to production capacity, the quantity of available molds, demand satisfaction and other operational constraints. The main objectives are related to the way to maximize the utilization of manufacturing resources and minimize mold movements. We developed a deterministic crowding genetic algorithm for this multi-objective problem. The algorithm has proved to be a powerful and flexible tool to solve large-scale instances of this real and complex scheduling problem. A genetic optimization procedure is also proposed to search for schedules using genetic algorithms for this multi-objective problem, such that makespan is minimized. One set of real production data were collected to validate the proposed method. Experimental results indicate that the genetically optimized schedules not only improve the operation performance but also minimize the scheduling risks.
