Optimization and collaboration model of supply chain inventory based on different delivery policies

According to actual operation of supply chain, the delivery model of agreement on lead time based on delivery windows is established, which is a Stackelberg game controlled by manufacturer. The optimal decision of each side is analyzed. Then controllable lead time model is established based on cost sharing. In the Stackelberg game controlled by distributor, the optimal decision is given. Delivery policy 1 and 2 are compared, and the range of cost sharing coefficient is given. Then cost sharing model with Nash consultation is proposed, based on adapted ideal point method. Finally, the policy 1 and 2 are compared in numerical analysis, which shows that the cost sharing model is effective.
