This research seeks to coordinate a multi-product two-level supply chain with one supplier and several retailers under inventory management contracts by the seller and cost sharing and cost minimization.
The case of this research is a two-level supply chain with a new construction material producer and 59 sales agents, which was finally optimized with the help of the presented model and Gemez software, and in order to validate and ensure the results obtained, the model sensitivity analysis has been done to the important parameters of the problem.
The findings indicate that according to the correctness of the presented model's performance in different conditions, it can be said that the presented model is responsive to different conditions and has sufficient credibility to solve problems.
With the help of supply chain coordinating contracts, supply chain costs can be effectively reduced, and of course, the effect of risk aversion of supply chain members on costs is significant and leads to an increase in maintenance costs, a decrease in shortage costs, and finally an increase in the overall costs of the supply chain.

In this study, a robust two-stage risk-aversion optimization model is proposed for the multi-product relief network design problem. The comprehensive set of decisions for locating and reinforcing relief facilities, inventory planning, and distributing healthcare items has been considered in an integrated manner. Uncertainties of relief facility capacity, relief demand, and the node linkage capacity are considered. Moreover, the weighted average expected loss is considered in the proposed robust planning model. The efficiency of the proposed model has been evaluated by examining numerical instances. The obtained results indicate the efficiency of the distributionally robust model compared to the traditional two-stage stochastic model. In addition, the type of ambiguous set and levels of confidence, risk aversion, and adjustment parameters will affect network performance.
