Automatic Generation of Production Scheduling by Genetic Algorithm

In many manufacturing companies, the need of an efficient inventory has become important. Our research is done in collaboration with an actual manufacturing company to improve the strategy for controlling inventory of the company. We focus on the production schedule used in the actual manufacturing company since it controls the inventory. The production schedule is formulated as an optimization problem. Based on the formulation, Genetic Algorithm (GA) is applied to generate a production schedule which satisfies an efficient inventory. The production schedules derived by GA are compared with the production schedules described by an expert. The effectiveness of GA is shown in the results and the discussions.
