【摘要】：現(xiàn)有的商業(yè)信用條件下有關(guān)于易變質(zhì)品的庫(kù)存模型的研究文獻(xiàn),通常假設(shè)供應(yīng)商給零售商的信用期M是固定的,還有一些是假設(shè)需求是固定的或受價(jià)格影響的,較少地討論下游的需求是受信用期影響。但是在現(xiàn)實(shí)生活中,零售商提供給顧客的信用期N對(duì)需求會(huì)有較大的影響,N越長(zhǎng),顧客可能購(gòu)買的商品越多,對(duì)商品的需求就越大,尤其是對(duì)于手頭上資金不充足的顧客更是如此。而供應(yīng)商給零售商的信用期M一般是根據(jù)訂購(gòu)批量Q的大小來確定的。訂購(gòu)批量越大,供應(yīng)商愿意提供的信用期就越長(zhǎng)。通過考慮信用期N對(duì)需求的影響以及定購(gòu)批量Q對(duì)信用期M的影響,建立了分散獨(dú)立決策庫(kù)存系統(tǒng)的數(shù)學(xué)模型,通過分析對(duì)象的利潤(rùn)最大化,用近似替代的方法確定了最優(yōu)訂購(gòu)周期T、最優(yōu)訂購(gòu)批量Q以及信用期M。同時(shí),給出了分散獨(dú)立決策庫(kù)存系統(tǒng)求解近似算法。最后進(jìn)行了數(shù)值分析和敏感性分析來探討和分析建立的模型。并從中得到了一些結(jié)論和管理啟示。
[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.
