【摘要】：随着供应链全球化和生产精益化的深入,以及恐怖主义、自然灾害等频繁发生,供应中断风险发生的概率正在逐步增加。目前,很多企业意识到了供应中断发生所产生的巨大负面影响,并开始积极探索应对供应中断风险的有效措施。突发事件导致的供应中断风险会给供应链下游成员造成非常严重甚至无法挽回的损失,为了抵御风险,下游企业必须做好事前事后各方面应对措施,在对风险要素进行合理分析的基础上,制定并实施有效的防范和应急策略。本文基于供应中断风险研究零售商采购策略选择和订货批量分配问题,从定量的角度为企业提供了中断风险的应急和防范措施,也为管理人员进行供应链管理决策提供支持。首先在对零售商面临的供应中断风险及应对措施进行分析的基础上,得出零售商的两种订货模式：应急采购和双源采购模式。然后,在随机市场需求下,从零售商利润最大化的角度研究了两种模式下的最优订货策略,包括应急模式下零售商如何使用后备资源以及双源模式下如何分配订单,进一步地,研究了服务水平约束下零售商的订货问题。同时,通过数值计算对不同采购模式进行了比较,并分析了中断概率、惩罚成本、服务水平等要素对最优策略产生的影响。
[Abstract]:With the deepening of supply chain globalization and lean production, as well as the frequent occurrence of terrorism and natural disasters, the probability of supply interruption risk is gradually increasing. At present, many enterprises have realized the huge negative impact of supply interruption, and began to actively explore the effective measures to deal with the supply interruption risk. The risk of supply interruption caused by unexpected events will cause very serious or even irreparable losses to the downstream members of the supply chain. In order to resist the risks, downstream enterprises must do a good job in all aspects of the countermeasures before and after the event. On the basis of reasonable analysis of risk factors, effective preventive and emergency strategies are formulated and implemented. Based on the research of supply interruption risk, this paper studies the problem of retailer purchasing strategy selection and order batch allocation, which provides emergency and preventive measures for enterprises from a quantitative point of view, and also provides support for managers to make supply chain management decisions. Firstly, based on the analysis of the supply interruption risk faced by retailers and the corresponding measures, two kinds of ordering modes of retailers are obtained: emergency purchasing and dual-source purchasing. Then, in the stochastic market demand, the optimal ordering strategies in two modes are studied from the perspective of maximizing retailer profit, including how retailers use backup resources in emergency mode and how to allocate orders in dual-source mode. The ordering problem of retailers under the constraint of service level is studied. At the same time, the different purchasing modes are compared by numerical calculation, and the effects of interruption probability, penalty cost and service level on the optimal strategy are analyzed.
