Automated stereo-garage with multiple cache parking spaces—Structure, system and scheduling performance

Abstract Stereo garage is kind of large capacity parking equipment to alleviate the parking problem. In order to reduce the construction cost and improve the garage performance, this paper introduces an automated stereo-garage with multiple cache parking spaces. The structure of the garage is simplified into a stacker and several storage units, and multiple cache parking spaces are set up. Two scheduling strategies are designed to improve the efficiency of the garage and reduce the process time consumption of customers, respectively. The running time under these two strategies is expressed mathematically, followed by the input data of the garage and its analyzed statistical regularity. Subsequently, operation processes of the garage during busy periods are simulated, and its service performance is analyzed by means of queuing theory. Results and comparisons show the superiority of the proposed garage system, and combined scheduling recommendations are provided for improving the overall working performance of the equipment.
