不对称信息下的易逝品退货物流协调运作研究

Study on Coordination Operations of Perishable Product Returns with Asymmetric Information

退货是当前企业面临的一个重要问题,越来越多的企业开始将退货物流外包给第三方物流企业。在由第三方物流企业和制造商构成的易逝品逆向物流系统中,第三方物流企业的退货处理速度直接影响制造商退货产品的收益,因此确定合适的退货处理速度,协调两者间的利益分配成为研究的重点。本文采用排队模型求出系统最优的退货处理速度,并讨论了影响最优处理速度的各个因素;最后通过构建信息甄别模型求出了在双方对第三方物流企业的成本类型存在信息不对称时,制造商的最优协调策略。

Manufacturers and distributors must cope with the increased flow of returned products from their customers. In response, many firms outsource their reverse logistics to TPL. If TPL handles returns faster, manufacturer can obtain more profit from returns, but leading to higher cost of TPL. So it is important to decide the optimal handling speed and allocation of total profit created by faster handling speed. In this paper we investigate the optimal handling speed by using the queueing model and discuss the factors influencing optimal handling speed. At last we establish a screening game model to get manufacturer＇ s optimal strategy when he can＇ t get the full information about TPL＇s handling cost type.
