【摘要】：随着全球化的不断深入和发展,产品生命周期缩短、市场需求的不确定性加剧,市场竞争由企业之间的竞争演变成供应链之间的竞争。供应链中各成员从自身收益出发,易发生利益冲突,使供应链效率降低,对供应链进行协调以提高供应链整体效益势在必行。契约作为供应链协调的重要机制可以在供应链协调中发挥很大作用。供应链成员的行为因素影响其决策,进而影响契约对供应链的协调效果。因此研究在不确定需求下考虑行为因素如何用契约协调供应链决策以提高供应链的运作效率具有重要的理论和现实意义。本文的研究工作主要包括以下几个方面：(1)模糊需求下三级供应链契约协调研究。在三角模糊数理论和供应链契约协调模型的基础上,分别构建了分散无协调、集中决策、收益共享契约协调及数量折扣契约协调四种情况的模糊需求下三级供应链决策模型。运用Stackelberg主从对策理论和多元线性方程对模型进行求解。通过算例分析证明收益共享契约和数量折扣契约都能在一定程度上实现对供应链的协调。(2)模糊需求下三级供应链联合契约协调研究。设计了由数量折扣契约和收益共享契约构成的联合契约,建立了模糊需求下三级供应链联合契约协调模型。对模型进行求解并通过算例分析得出,此种联合契约比单一的收益共享契约或数量折扣契约对供应链有更好的协调效果。(3)模糊需求下三级供应链考虑公平偏好的联合契约协调研究。假设供应链中多个零售商具有不同公平偏好,构建了模糊需求下三级供应链联合契约协调效用模型。对模型进行求解并通过算例分析得出,零售商的公平偏好,不会影响联合契约对模糊需求下三级供应链的协调性。但零售商的公平偏好程度越高,其对供应链的效用影响越大。本文构建的模糊需求下三级供应链联合契约协调模型以及对多个零售商公平偏好的考虑,更加符合供应链运作的实际背景,丰富、充实了供应链管理领域的研究,对提高供应链运作效率具有实际参考价值。
[Abstract]:With the deepening and development of globalization, the product life cycle is shortened and the uncertainty of market demand intensifies. Market competition evolves from competition between enterprises to competition between supply chains. It is imperative to coordinate the supply chain in order to improve the overall benefit of the supply chain because the members of the supply chain are prone to conflict of interest from their own income and reduce the efficiency of the supply chain. As an important mechanism of supply chain coordination, contract can play an important role in supply chain coordination. The behavior factors of supply chain members influence their decision making and the coordination effect of contract on supply chain. Therefore, it is of great theoretical and practical significance to study how to coordinate supply chain decisions by contract in order to improve the operational efficiency of supply chain under uncertain demand. The research work of this paper mainly includes the following aspects: 1) contract coordination of three-level supply chain under fuzzy demand. On the basis of triangular fuzzy number theory and supply chain contract coordination model, the three-level supply chain decision model under fuzzy demand is constructed, which includes decentralized non-coordination, centralized decision-making, revenue-sharing contract coordination and quantity discount contract coordination. The model is solved by using Stackelberg master-slave game theory and multivariate linear equations. Through the example analysis, it is proved that both the revenue-sharing contract and the quantity discount contract can achieve the coordination of supply chain to a certain extent. A joint contract consisting of quantity discount contract and revenue sharing contract is designed, and the coordination model of joint contract in three-level supply chain under fuzzy demand is established. The model is solved and analyzed by an example. This kind of joint contract has better coordination effect on supply chain than single profit-sharing contract or quantity discount contract. Assuming that many retailers in the supply chain have different fairness preferences, a three-level supply chain joint contract coordination utility model is constructed under fuzzy demand. By solving the model and analyzing an example, it is concluded that the fairness preference of retailers will not affect the coordination of three-level supply chain under fuzzy demand by joint contract. However, the higher the retailer's fair preference, the greater the impact on supply chain utility. The joint contract coordination model of three-level supply chain under fuzzy demand and the consideration of the fairness preference of many retailers are more in line with the actual background of supply chain operation and enrich the research of supply chain management. It has practical reference value for improving the efficiency of supply chain operation.
