Abstract:We herein tackled concurrent design of machines layout and automated guided vehicle (AGV) planning in a workshop, and proposed a co-evolutionary framework for the whole design with tandem AGVs system. Our objective is to reduce the material transporting costs in the manufacturing process and realize the flexible reconfigurable. Firstly, we divide the whole workshop into several regions (or groups), and each region is a subsystem of cooperative co-evolutionary (CC) framework (Potter's CC model). Then, we employ a typical evolutionary algorithm, such as genetic algorithm, to solve the machine layout with AGV planning in each region. Also, we use a group generator to regroup the regions for improving the design. The preliminary experimental results from an example with ten parts, 30 machines and three loops in a workshop showed the effectiveness of our framework compared with noncoevolutionary framework.
