【摘要】：随着市场需求不确定性的增加,企业之间的竞争逐渐增大,供应链协调已成为企业提高竞争力的关键.传统的供应链研究中,大多假设供应链成员是完全理性的.现实生活中,由于受众多因素的影响,供应链成员往往做出非理性的行为,如过度自信、风险厌恶、公平关切等,这些行为会对供应链整体造成一定的影响,尤其是过度自信行为.为此,本文基于期权契约和数量弹性契约对过度自信的零售商参与的供应链协调情况进行研究.本文考虑由一个过度自信的零售商和一个理性的供应商组成的二级供应链,将期权契约和数量弹性契约引入到供应链中,研究契约下供应链的最优订货策略以及协调情况.首先,在信念需求下,建立了分散决策模式下的契约模型,并求解出过度自信零售商的最优订货量;其次,在集中决策模式下,考虑供应链系统的决策者具有过度自信行为,并在决策者的信念需求下建立契约模型,求解出供应链系统的最优订货量;再次,将分散决策与集中决策下的最优订货量作比较,给出协调条件,并根据协调定义讨论供应链的协调情况;最后,通过数值算例对理论结果进行验证,并讨论了过度自信程度对零售商和供应链系统的期望利润的影响.研究结果表明:在一定的条件下,期权契约和数量弹性契约均可以有效地协调供应链;并且,当过度自信达到一定程度后,零售商的过度自信利润大于理性时的实际期望利润,供应链系统的过度自信利润大于理性时的实际期望利润,影响供应链的绩效。
[Abstract]:With the increasing uncertainty of market demand, the competition between enterprises increases gradually, and supply chain coordination has become the key to improve the competitiveness of enterprises. In the traditional supply chain research, most of the supply chain members are assumed to be completely rational. In real life, due to the influence of many factors, supply chain members often make irrational behavior, such as overconfidence, risk aversion, fair concern, and so on, which will have a certain impact on the whole supply chain. Especially overconfident behavior. Therefore, based on option contract and quantitative elasticity contract, this paper studies the coordination of overconfident retailers in supply chain. In this paper, a two-level supply chain composed of an overconfident retailer and a rational supplier is considered. The option contract and the quantity elasticity contract are introduced into the supply chain, and the optimal ordering strategy and coordination of the supply chain under the contract are studied. Firstly, under the belief demand, the contract model under the decentralized decision model is established, and the optimal order quantity of overconfident retailer is solved. Secondly, under the centralized decision mode, the decision makers in the supply chain system are considered to have overconfidence behavior. Under the belief demand of the decision maker, the contract model is established to solve the optimal order quantity of the supply chain system. Thirdly, the coordination conditions are given by comparing the decentralized decision with the optimal order quantity under the centralized decision. Finally, the theoretical results are verified by numerical examples, and the influence of overconfidence on the expected profits of retailers and supply chain systems is discussed. The results show that the option contract and the quantitative elastic contract can effectively coordinate the supply chain under certain conditions, and when the overconfidence reaches a certain level, the retailer's overconfidence profit is larger than the actual expected profit when rational. The overconfidence profit of the supply chain system is larger than the actual expected profit of the rational system, which affects the performance of the supply chain.
