【摘要】：供应链环境下订货与交付问题的研究是当前学术界非常关注的一个问题。一个好的订货与交付策略不但可以降低供应链系统的总成本、提高供应链系统的效率,还可以灵活的选择不同的频率为不同的零售商交付产品,并应对由市场需求不确定给各个零售商带来的缺货损失,保证一定的服务水平,同时平衡由于零售商之间服务水平的差异化而产生的不公平性问题。因此,本文选择单供应商多零售商两级供应系统的订货与交付联合优化问题作为研究对象,构建不相等交付频率下考虑均衡性的订货与交付联合优化模型,达到企业经济效益和各个零售商服务水平均衡性兼顾的整体最优目标,具有重要的理论意义与应用意义。本文研究的主要内容包括以下方面：(1)相等交付频率下订货与交付联合优化模型构建。在相等交付频率下,将零售商的订货过程与供应商的交付过程联合起来考虑,构建订货与交付联合优化模型,并在需求不确定条件下,通过对模型进行分析,得出合理的订货与交付联合优化策略。(2)不相等交付频率下考虑均衡性的订货与交付联合优化模型构建。在需求不确定条件下,对不同的零售商采用更加灵活的不相等交付频率策略,同时将以往只考虑成本的研究模式转变为兼顾服务水平均衡性和经济因素的研究,考虑服务水平均衡性因素,通过对不相等交付频率的处理和对服务水平均衡性因素的分析,得出合理的订货与交付联合优化策略。(3)基于禁忌搜索算法的模型求解及应用实例分析。以沈阳宝钢钢材配送中心的不锈钢产品供应链系统为例,对构建的模型采用混合禁忌搜索算法(Mixed Tabu Search Algorithm)进行求解,为企业决策提供合理的订货与交付支持。通过应用实例分析,验证本文模型的有效性。本文提出的不相等交付频率下考虑均衡性的订货与交付联合优化模型是对供应链中订货与交付问题研究的丰富；同时,本文研究的服务水平均衡性因素为企业保持与客户的合作关系、提高客户的忠诚度提供了有价值的运作指导。
[Abstract]:The research of ordering and delivery in supply chain environment is a problem that the academic circles pay close attention to. A good ordering and delivery strategy can not only reduce the total cost of the supply chain system and improve the efficiency of the supply chain system, but also flexibly select different frequencies for different retailers to deliver products. It also deals with the shortage loss caused by the uncertainty of market demand to ensure a certain service level and balance the unfairness caused by the difference of service level among retailers. Therefore, this paper chooses the joint optimization problem of ordering and delivery for single-supplier, multi-retailer and two-level supply system as the research object, and constructs a joint optimization model of ordering and delivery considering equilibrium under unequal delivery frequency. It is of great theoretical and practical significance to achieve the overall optimal goal of enterprise economic benefit and the balanced service level of each retailer. The main contents of this paper are as follows: (1) the joint optimization model of ordering and delivery with equal delivery frequency is constructed. Under the equal delivery frequency, the retailer's ordering process and the supplier's delivery process are considered together, and the optimal model of ordering and delivery is constructed, and the model is analyzed under the condition of uncertain demand. A reasonable joint optimization strategy for ordering and delivery is obtained. (2) the joint optimization model of ordering and delivery considering equilibrium is constructed under unequal delivery frequency. Under the condition of uncertain demand, we adopt more flexible unequal delivery frequency strategy for different retailers. At the same time, we change the former research mode which only considers the cost to consider the balance of service level and economic factors. Taking into account the service level equilibrium factor, through the treatment of unequal delivery frequencies and the analysis of service level equilibrium factors, A reasonable joint optimization strategy of ordering and delivery is obtained. (3) Model solving based on Tabu search algorithm and application example analysis. Taking the stainless steel product supply chain system in the steel distribution center of Shenyang Baosteel as an example, the model is solved by using the mixed Tabu search algorithm (Mixed Tabu Search Algorithm) to provide reasonable order and delivery support for enterprise decision. The validity of the model is verified by an application example. The joint optimization model of ordering and delivery considering equilibrium in unequal delivery frequency proposed in this paper is rich in the research of ordering and delivery problem in supply chain, and at the same time, The equilibrium factors of service level studied in this paper provide valuable operational guidance for enterprises to maintain cooperative relationship with customers and improve customer loyalty.
