【摘要】：供应链协调是供应链管理的一个重要组成部分,协调的目的是为了提高供应链的整体利益。为了提高供应链的整体利益,通常采用契约协调机制对供应链的节点企业进行激励,促使他们做出最有利于供应链整体利益的决策。传统供应链管理理论通常将决策者假设为完全理性的“经济人”,但人的行为因素可能会影响供应链最优决策的制定。这些行为因素,例如公平偏好、风险偏好等,会导致人们做决策时不总是遵循利润最大化的原则。为此,引入行为因素的效用模型得出的最优决策更能符合实际情况。首先,本文在随机供求的背景下,以期望利润最大化为目标建立了供应商、制造商和零售商的三级供应链集中决策和分散决策模型,证明出存在最优决策,并比较了集中决策和分散决策的均衡解,研究发现分散决策没有使供应链达到协调。其次,分别建立了使用回购契约和联合契约的协调模型,得到了使供应链达到协调的契约参数的最优设定,通过算例分析出仅使用回购契约存在局限性,而联合契约能够更好地使供应链达到协调。然后,引入公平偏好因素,构建了供应商、制造商和零售商均具有公平偏好时的效用模型,来考察供应链成员的公平偏好对三级供应链的联合契约协调性的影响。研究发现公平偏好会对联合契约最优参数设定产生影响,也会对最优决策产生影响。最后,通过算例分析发现公平偏好程度越大,其对效用的影响程度也越大。
[Abstract]:Supply chain coordination is an important part of supply chain management, the purpose of coordination is to improve the overall interests of supply chain, in order to improve the overall interests of supply chain, the contract coordination mechanism is usually used to stimulate the node enterprises of supply chain. The traditional supply chain management theory usually assumes the decision-maker as a completely rational "economic man", but the human behavior factors may affect the system of the optimal decision of the supply chain. These behavioral factors, For example, fairness preference, risk preference and so on will lead people to make decisions that do not always follow the principle of profit maximization. For this reason, the optimal decision based on the utility model with behavioral factors is more suitable to the actual situation. In this paper, under the background of stochastic supply and demand, the centralized and decentralized decision models of supplier, manufacturer and retailer are established to maximize the expected profit, which proves the existence of optimal decision. The equilibrium solutions of centralized decision and decentralized decision are compared. It is found that decentralized decision does not make the supply chain coordinate. Secondly, the coordination model using repurchase contract and joint contract is established, respectively. The optimal setting of contract parameters for coordination of supply chain is obtained, and the limitation of using repurchase contract only is analyzed through an example, while the joint contract can make supply chain coordinate better. Then, the fair preference factor is introduced. The utility model of suppliers, manufacturers and retailers with fair preference is constructed. In order to investigate the influence of the fairness preference of supply chain members on the coordination of joint contracts in three-level supply chain, it is found that fair preference will have an impact on the setting of the optimal parameters of the joint contract as well as on the optimal decision. Finally, It is found that the greater the degree of fairness preference, the greater the impact on utility.
