The supply chain in the new retail context demands higher requirements on the price, service, and logistics level. It is very important to seek the coordination among the optimal price, service level, and logistics level. In this paper, we propose the coordination of pricing, the service level, and delivery time of a new retail supply chain composed of one product supplier, one platform service provider, and one logistics provider. Firstly, the profit function mode of product pricing, platform service level, and logistics distribution level that influence the consumers’ demand is constructed in two modes, namely, the centralized and decentralized decision mode. Then, we calculate and compare the optimal product price, the optimal platform service level, the optimal delivery time, and the profit of each member of the supply chain from both decision modes. We discovered that cooperation improves the service level, logistics level, and the income of each member of the new retail supply chain. Therefore, we propose a novel mode called the coordination mode as a strategy for the supply chain based on the combination contract. We performed a numerical analysis to demonstrate the feasibility and effectiveness of the coordination contract.

基于组合合同的新型零售供应链协调策略

在新的零售环境中，供应链对价格，服务和物流水平有更高的要求。在最佳价格，服务水平和物流水平之间寻求协调非常重要。本文提出了由一个产品供应商，一个平台服务提供商和一个物流提供商组成的新零售供应链的定价，服务水平和交货时间的协调。首先，建立了影响消费者需求的产品定价，平台服务水平和物流配送水平的利润函数模型，即集中决策模型和分散决策模型两种。然后，我们计算并比较最佳产品价格，最佳平台服务水平，最佳交货时间，以及两种决策模式下供应链每个成员的利润。我们发现合作可以提高服务水平，物流水平以及新零售供应链中每个成员的收入。因此，我们提出了一种新的模式，称为协调模式，作为基于联合合同的供应链策略。我们进行了数值分析，以证明协调合同的可行性和有效性。
