Abstract: A three-level supply chain composed of a manufacturer, a third party logistics supplier, and a retailer for medical protective goods is considered in this paper. With random demands considered, it analyzes the impact of public health emergency on the supply chain in the viewpoint of the revenue sharing contract. Results show that the supply chain is able to cope with such emergency by adjusting the wholesale prices of products and logistics service price in transfer payments such that the original revenue sharing contract can be improved under emergency. This makes the supply chain have not only the ability of antidisruption, but also can reasonably redistribute the profits among the members of the supply chain.
