立体车库随机车位分配与就近车位分配仿真及分析

Simulation and Analysis on Laneway Stowed Parking System Random Access and Handy Access

在介绍巷道堆垛式自动化立体车库工作的基础上,建立了约束条件下的车辆入库、出库、因车位存满而离去的就近存取和随机存取策略车库工作模型。以车辆到达时间间隔服从泊松分布,库内存放时间服从正态分布的情况建立数学模型,采用Matlab编制仿真程序,对特定参数的模型进行了仿真,并给出分析结果。结果表明在文中参数设定情况下该车库车位利用率较高,采用就近存取策略比采用随机存取策略堆垛机运行距离短,能耗低,全年能耗降低显著。

Based on analysis work mode of laneway stowed parking system,the handy access modal and random access modal of laneway stowed parking system are established which include car be put in storage,send out of storage and also leave storage because of none free park existed.The numerical modal built through car arrival submits to possion stream and storing time submits to normal distribution.Simulation procedure programmed by matlab.Using certain parameter the numerical modal simulates parking system＇s work procedure.At last the analysis of simulation is described.The result showed that this parking system had high park using ratio.The result also proved handy access modal had shorter running distance and lower energy consumption than random access modal.
