Abstract: To research the supply chain coordination problem of refund and deadline for returns among fresh products enterprise,logistics distribution enterprise and consumers,the returns deadline,price,freshness,preservation and charging strategy and optimal profit in centralized and decentralized decision were discussed.It was found that the centralized decision allowed for a longer return period with profit maximization.The increasing of the returns deadline would reduce the profit of logistics distribution enterprise when the returns deadline increased to a critical value,which was not willing to provide the corresponding fresh-keeping level.A contract coordination was designed,and it was found that Pareto optimality could be achieved when the charging strategy of logistics distribution enterprises in certain conditions.By changing the coefficient of the contract,the profit of supply chain system could be distributed between fresh products enterprise and logistics distribution enterprise.

Key words: fresh products, returns deadline, home delivery mode, supply chain coordination, revenue-sharing and cost-allocation

摘要： 为研究生鲜电商企业与配送企业,以及消费者组成的存在退货且有退货期限的冷链宅配供应链协调问题,讨论了集中决策和分散决策下的退货期限、销售价格、新鲜度、保鲜努力程度、收费策略以及最优利润。研究发现,利润最大化时,集中式决策允许更长的退货期限;当退货期限达到某一数值后,提高退货期限会使配送企业的利润减少,致使其没有动力提供对应的保鲜水平。通过设计组合契约协调发现,在配送企业的收费策略满足一定条件时,可以实现帕累托最优,调整契约分摊系数可以实现利润在生鲜电商企业与配送企业间的不同分配。
