摘　　要：目的利用Flexsim软件仿真医药物流中心立体仓库的运作,缩短立体仓库出入库作业时间,优化运作过程人员与设备的组合。方法以某大型医药物流中心为研究对象,根据实际立体仓库的布局,使用Flexsim仿真软件进行建模仿真时,首先采用遗传算法确定最优的出入库顺序,将结果在Flexsim中仿真运行,证明算法用于出入库仿真的实用性;然后对立体仓库整体流程进行仿真。结果优化后的流程,出入库作业效率提高了12.4%,确立了仓储作业在(2,2,2,2)配置下,实现了人员设备的最优利用。结论采用建模仿真的方法,找出了流程中的瓶颈,确认了最优出入库作业顺序,以及人员、设备组合,提高了医药物流中心的出入库效率,降低了设备、人员等成本。The work aims to simulate the operations of stereoscopic warehouse of pharmaceutical logistics center with Flexsim, in order to shorten the time of out-put and in-put warehousing of stereoscopic warehouse and optimize the com- bination of personnel and equipment during the operation. Taking a large-scaled pharmaceutical logistics center as the research object, according to the actual layout of stereoscopic warehouse, a simulation model was built with Flexsim si- mulation software. First, genetic algorithm was used to determine the optimal out-put and in-put sequence, and the results were simulated in the Flexsim which could prove the practicability of the algorithm. Then, the whole process of stereos- copic warehouse was simulated. The efficiency of out-put and in-put warehousing was improved by 12.4% and the ware- housing that enabled the optimal use of personnel and equipment to be achieved under the configuration of （2,2,2,2） was established. With modeling and simulation, the bottlenecks of the process are identified, the optimal out-put and in-put warehousing sequence and combination of personnel and equipment are confirmed, the efficiency of out-put and in-put operation in pharmaceutical logistics center is improved, and the costs of equipment and personnel are reduced.
