【摘要】：随着人们消费水平的提高,零售企业正面临着多样化的小众市场。为迎合客户的个性需求,提高客户服务满意度,零售业对物流活动效率提出了更新的要求。配送中心作为供应链中关键的节点,承担着产品从上游供应商到下游零售商物流活动的责任,对供应链的整体运营有重要影响。为加快产品流通、及时满足客户需求,现对配送中心的补货与配送环节进行联合优化研究。本文以零售业配送中心为研究对象,以节省物流活动时间、提高利润为目标,分别研究了单一产品与多种产品的配送中心补货配送优化问题。本文首先介绍供应链管理的有关知识,以零售业配送中心库存变化情况和相关库存费用为基础,给出了存储模型、配送模型及其相关的求解算法。其次,针对现有供应链环境下,配送中心对单一产品的补货配送过程中较少考虑分组配送策略,结合零售商地理位置、对产品需求量不同等特点,引入分组决策变量。根据配送中心的补货周期与配送次数两个变量间的函数关系,建立了以三级供应链系统的平均总成本最小为目标的补货配送优化模型。通过分析模型的特点,设计求解算法并进行实例仿真,验证了模型的有效性。最后,分析了配送中心对多种产品的补货配送过程,考虑到不同属性的产品同时运输时会增加额外运输成本的实际情况,且不同产品的补货周期、配送次数不尽相同等因素,构建了带有配送中心服务能力约束的数学规划模型。根据数学模型的特征选择遗传算法求解。实例仿真的结果表明,该模型为配送中心提供的多种产品补货配送策略具有可行性。本文研究了配送中心对于不同产品的补货配送物流活动过程,通过模型给出的管理方案有现实意义,并为配送中心优化补货配送过程提供了管理启示,合理利用了中心内部资源,有助于配送中心更好的满足客户需求。本文所做的工作为配送中心补货配送优化问题的研究作了尝试和努力。
[Abstract]:With the improvement of people's consumption level, retail enterprises are facing a variety of niche market. In order to meet the individual needs of customers, improve customer service satisfaction. As a key node in the supply chain, the distribution center is responsible for the logistics activities from the upstream suppliers to the downstream retailers. Has an important impact on the overall operation of the supply chain. In order to speed up the circulation of products, timely meet customer needs. This paper takes the retail distribution center as the research object, in order to save the time of logistics activities, improve the profit as the goal. This paper first introduces the knowledge of supply chain management, based on the changes of retail distribution center inventory and related inventory costs. The storage model, distribution model and its related algorithms are given. Secondly, in the current supply chain environment, the distribution center for a single product replenishment delivery process less consideration of the grouping distribution strategy. According to the geographical location of retailers and the different characteristics of product demand, a group decision variable is introduced, which is based on the functional relationship between the replenishment cycle of distribution center and the number of distribution. A replenishment distribution optimization model with the minimum average total cost of the three-level supply chain system is established. By analyzing the characteristics of the model, a solution algorithm is designed and an example simulation is carried out to verify the effectiveness of the model. This paper analyzes the restocking distribution process of various products in the distribution center, considering the actual situation that the additional transportation cost will be increased when the products with different attributes are transported simultaneously, and the replenishment cycle of different products is taken into account. In this paper, a mathematical programming model with service capacity constraints of distribution center is constructed, and the genetic algorithm is selected to solve the problem according to the characteristics of the mathematical model. This model has the feasibility for the distribution center to provide a variety of product replenishment distribution strategy. This paper studies the distribution center for different products of replenishment distribution logistics process. The management scheme given by the model is of practical significance and provides the management inspiration for the distribution center to optimize the restocking distribution process and make rational use of the inner resources of the center. It is helpful for the distribution center to better meet the needs of customers. The work done in this paper is an attempt and effort for the research of the distribution center replenishment distribution optimization problem.
