第四方物流与第三方物流构成委托代理关系,信息不对称与风险规避为第四方物流配送时间契约设计带来了难题.对此,分别在集中式决策、对称成本信息和不对称成本信息3种情景下进行研究,给出最优配送时间契约,并对最优契约结果进行分析.实验结果表明:最优契约能够实现对第三方物流的激励,有效地管理物流配送时间;同时,不对称信息与风险规避均会降低系统表现.数值实验说明了不对称信息与风险规避对最优配送时间契约的影响.
Fourth party logistics and third party logistics constitute a principal-agent relationship. Due to the asymmetric information and risk averse, it is difficult to design fourth party logistics delivery time contract, which is studied in the centralized decision-making, symmetric cost information and asymmetric cost information scenarios respectively. The optimal delivery time contract is obtained and the optimal results are analyzed. Results show that the optimal contract can incite the third party logistics, and manage the delivery time effectively. However, both the asymmetric information and risk averse can reduce the channel performance. The numerical experiment is given to show the effect of asymmetric information and risk averse on the optimal delivery time contract.
