Optimization of Transactions in the Plant and Flower Organized Market Considering Third-Party Logistics Company under Uncertainty

In this paper, we consider plant and flower organized exchange market configuration as an optimization problem. Stakeholders in plant and flower organized market problem are supplier, buyer, third-party logistics company, broker and exchange market agent. Plants and flowers are a subset of fresh products and also fresh products are a sub-category of perishable products. In this paper two leader-follower Stackelberg model between supplier and buyer and also between buyer and third-party logistics provider will be proposed. We drive the optimal order quantity, selling and retail price in the first model and optimal transportation price in the second model. At the end, a coordinated and integrated model will be proposed in which all members of the supply chain will try for overall chain profit. Then the expected profits, order quantity, and retail price of the competitive mode and the coordinated model are compared with respect to given numerical example. The results show higher profit and order quantity and lower the retail price in a coordinated mode compared to competitive model.
