变化信用期下易变质品分散独立决策供应链系统
发布时间：2018-11-25 11:34
【摘要】：现有的商业信用条件下有关于易变质品的库存模型的研究文献,通常假设供应商给零售商的信用期M是固定的,还有一些是假设需求是固定的或受价格影响的,较少地讨论下游的需求是受信用期影响。但是在现实生活中,零售商提供给顾客的信用期N对需求会有较大的影响,N越长,顾客可能购买的商品越多,对商品的需求就越大,尤其是对于手头上资金不充足的顾客更是如此。而供应商给零售商的信用期M一般是根据订购批量Q的大小来确定的。订购批量越大,供应商愿意提供的信用期就越长。通过考虑信用期N对需求的影响以及定购批量Q对信用期M的影响,建立了分散独立决策库存系统的数学模型,通过分析对象的利润最大化,用近似替代的方法确定了最优订购周期T、最优订购批量Q以及信用期M。同时,给出了分散独立决策库存系统求解近似算法。最后进行了数值分析和敏感性分析来探讨和分析建立的模型。并从中得到了一些结论和管理启示。
[Abstract]:Existing research literature on inventory models of perishable goods under commercial credit conditions generally assumes that the credit period M given by suppliers to retailers is fixed, and some assume that demand is fixed or affected by price. Less discussion of downstream demand is affected by credit periods. However, in real life, the credit period N provided by retailers to customers will have a greater impact on demand. The longer N is, the more goods customers may buy, and the greater the demand for goods. This is especially true for customers who do not have enough money on hand. The credit period M of supplier to retailer is usually determined by the quantity Q of order. The larger the order volume, the longer the credit period the supplier is willing to offer. By considering the influence of credit period N on demand and the influence of purchase quantity Q on credit period M, the mathematical model of decentralized independent decision inventory system is established. The profit maximization of the object is analyzed. An approximate substitution method is used to determine the optimal ordering cycle T, the optimal order batch Q and the credit period M. At the same time, an approximate algorithm for solving decentralized independent decision inventory system is presented. Finally, numerical analysis and sensitivity analysis are carried out to discuss and analyze the established model. And got some conclusions and management enlightenment.
