In order to meet the demand of automated guided vehicle (AGV) as transport carrier in final assembly workshop, the AGV design scheme is optimized to enhance the function of AGV transport system. Based on the operation of a passenger car assembly workshop, the AGV conveying line is designed, and combined with the workshop conveying design scheme, AGV characteristics, the operational logic of the line and the line business process, the AGV conveying system simulation model is constructed by using Siemens Plant Simulation software soas to analyze the number of AGVs at different beats. In order to meet the production cycle time, the design of experiment (DOE) method is carried out through the design of test manager, and the charging time walking speed of the automatic workstation is optimized to cache the battery capacity of the AGV between the lines. After optimization, the conveying efficiency of AGV line is increased by 24%, and the utilization rate of AGV is increased by 26%。
