In order to improve the operation efficiency of stereo garage, the equipment configuration of planar mobile stereo garage under different access task arrival rates was studied. The planar mobile stereo garage was modeled as a semi-open queueing network model. According to the different access vehicle locations of the stereo garage, 10 kinds of access vehicle process operation scenarios were analyzed. The evaluation indexes of the stereo garage were defined as the service time of customer access vehicle and the operation energy consumption of access vehicle process equipment. The semi-open queueing network model of planar mobile stereo garage is optimized and solved from the perspectives of customer satisfaction and garage operator, through the simulation analysis under different customer arrival rate, each handling equipment and elevator configuration combinations on customers in the system access vehicle service time and the impact of energy consumption, the simulation results show that: The analysis of the stereo garage resource configuration combination can effectively improve the system operation efficiency under different arrival rates, and provide decision support for the optimal design of the system, improve the utilization rate of equipment, and save the systematic operation cost.
