【摘要】：隨著經(jīng)濟(jì)全球化和信息技術(shù)的快速發(fā)展，企業(yè)所處的競爭環(huán)境發(fā)生了根本性的變化，市場競爭由原來的產(chǎn)品價格、質(zhì)量等傳統(tǒng)因素的競爭轉(zhuǎn)向了時間、品牌等因素的競爭，由單個企業(yè)之間的競爭轉(zhuǎn)向了供應(yīng)鏈之間的競爭。供應(yīng)鏈管理已成為一種新的庫存管理理念和方法。 本文考慮一個由供應(yīng)商、零售商組成的二級供應(yīng)鏈庫存系統(tǒng)，其中供應(yīng)商有兩種類型：普通供應(yīng)商和緊急供應(yīng)商。在兩階段需求相關(guān)的報童模型框架下，研究零售商的最優(yōu)訂貨策略，建立了兩階段動態(tài)規(guī)劃模型。 第一章介紹了庫存管理問題、報童模型、緊急供應(yīng)商問題與一些預(yù)備知識，并介紹了本文的主要研究內(nèi)容。 第二章，研究含緊急供應(yīng)商的兩階段需求相關(guān)的報童模型，零售商在第一階段發(fā)生缺貨時有一次緊急補(bǔ)貨機(jī)會。通過對零售商在兩個階段內(nèi)的利潤分析，建立了動態(tài)規(guī)劃模型，并給出了模型求解的算法。最后，，結(jié)合數(shù)值算例驗證了算法的有效性，在靈敏度分析部分給出了需求相關(guān)系數(shù)對零售商訂貨決策與利潤的影響。 第三章，在允許部分缺貨回補(bǔ)和有緊急供應(yīng)商的條件下，對有相關(guān)需求的兩階段報童模型進(jìn)行研究。零售商在第一階段發(fā)生缺貨時面臨兩種補(bǔ)貨策略：部分缺貨回補(bǔ)和緊急補(bǔ)貨策略。針對不同的補(bǔ)貨策略，分別對零售商在兩個階段內(nèi)的利潤進(jìn)行分析，建立了求解零售商最優(yōu)訂貨策略的動態(tài)規(guī)劃模型，并給出了模型求解的算法。最后，給出數(shù)值算例，并通過靈敏度分析得出各參數(shù)對零售商訂貨決策的影響。
[Abstract]:With the rapid development of economic globalization and information technology, the competitive environment in which enterprises are located has undergone fundamental changes. The competition in the market has changed from the traditional factors such as product price and quality to those of time and brand. From competition among individual enterprises to competition between supply chains, supply chain management has become a new concept and method of inventory management. In this paper, we consider a two-stage supply chain inventory system composed of suppliers and retailers, in which there are two types of suppliers: ordinary suppliers and emergency suppliers. The optimal ordering strategy of retailers is studied and a two-stage dynamic programming model is established. The first chapter introduces the inventory management problem, newsboy model, emergency supplier problem and some preparatory knowledge, and introduces the main research contents of this paper. In the second chapter, the paper studies the newsboy model related to the two-stage demand of the emergency supplier. The retailer has an emergency replenishment opportunity in the first stage, through the analysis of the retailer's profit in the two stages. The dynamic programming model is established and the algorithm for solving the model is given. Finally, the effectiveness of the algorithm is verified by numerical examples. In the sensitivity analysis part, the influence of demand correlation coefficient on the order decision and profit of retailers is given. Chapter III, under the conditions of allowing partial backfill and emergency suppliers, This paper studies the two-stage newsboy model with related requirements. Retailers face two restocking strategies when they are out of stock in the first stage: partial shortage replenishment and emergency replenishment strategy. Based on the analysis of the retailer's profit in two stages, the dynamic programming model for solving the retailer's optimal ordering policy is established, and the algorithm for solving the model is given. Finally, a numerical example is given. Through sensitivity analysis, the influence of each parameter on retailer order decision is obtained.
