Abstract: The equipment layout design of traditional job-shop usually takes the straight-line distance or Manhattan distance between two devices as the optimization variables.And it does not consider the route of workpiece handling equipment in the actual production process.In smart job-shop,however,Automated Guided Vehicle(AGV)is the main workpiece handling equipment.Therefore,the actual logistics route and logistics efficiency must be considered.Based on AGV unidirectional guided-path network,handling frequency,per unit distance cost,and the shortest directed distance were used to establish the equipment layout design model of smart job-shop.And then,the Chaos Genetic Algorithm(CGA)to achieve the calculation of the model.At last,by the comparison of different equipment layout optimization algorithms and running simulation on Plant Simulation platform,an equipment layout design case of smart cylinder head production job shop was discussed to verify the feasibility and universality of the proposed models and methods.
