摘要：Precise control of hospital pharmacy inventory is an important guarantee for hospital. The optimal inventory policy for a multi-level medicine inventory control in hospital pharmacy was considered in this paper, and modeling simulation technology and intelligent optimization has been used. Analyzed with large-scale hospitals data, this paper has discussed the following problems: random fluctuations of demand in hospital departments, total volume limits and uncertainty response time of suppliers' delivery. Establish multilevel pharmaceutical inventory simulation model, then use PSO method for intelligent optimization. Examples of simulation models and PSO algorithms verified by numerical results show that: when each department was tested randomly varying demand of the patients, multi-level inventory management must be overall coordination in order to achieve optimum system.
