There are two forms of stacking type 3D-park: with car carrier plate and without car carrier plate. Compared with no car carrier plate way, the kind of exchange car carrier plate is no contact between stacker and vehicles and no damage to the vehicles. In order to solve the problems of low access efficiency and strong influence by people, which is existing in the stacking type automatic 3D-park, a new automatic 3D-park with car carrier plate cache device is put forward. According to analysis and comparison of the new automatic 3D-park and the original system, a mathematical model is built with average accessing time as objective function. Comparing the average service rate under a variety of storage-retrieval strategies with the actual vehicle arrival rate respectively, it shows that the automatic 3D-park with car carrier plate cache device greatly improves the access efficiency. The vehicle average service rate increased from 40.92/h to 63.99/h above.
