摘要
医药供应链是一个极其复杂的过程。以大型医药连锁超市的多药品订购问题为背景,在变质库存理论的基础上,将供应链协调机制引入医药库存理论研究,研究了时变需求下具有提前期的同一供应商向医药超市零售商不同专柜供货的库存订购策略模型。并通过计算机仿真,得到了多种药品订购的近似最优策略。最后,对理论进行了实证分析及灵敏度分析。结果表明:时变需求下,医药超市实行多药品订购时,联合补货策略为最优补货策略。
Medical supply chain is an extremely complex process.According to the multi-product ordering problems in medical chain supermarkets,the coordination mechanism is introduced into medical inventory research on the basis of perishable inventory theory.Research mainly focused on the multi-product ordering problems in medical chain supermarket under time-varying demand.The inventory shoppers of medical retailer under time-varying demands with a given lead time was established and analyzed.Use computer simulation to get the approximate optimal policy.By the empirical analysis and sensitivity analysis,the theoretical results are obtained which show JRP is the optimal policy in multi-product ordering in medical chain supermarket.
