Factory production plan-replenishment management robust joint decision optimization method

The invention relates to a factory production plan-replenishment management robust joint decision optimization method, and belongs to the technical field of supply chain management. Step 1, putting forward a reasonable hypothesis according to a problem; step 2, inputting basic data of the three-level supply chain network; step 3, establishing a factory production plan and DC replenishment strategy collaborative optimization model under uncertain requirements; 4, further converting the constructed collaborative optimization model containing the uncertain parameters into a standard mixed integer linear programming model; and step 5, using an optimization solver Gurobi to call a branch and bound method to solve the proposed factory production plan-replenishment management robust joint decision optimization model based on the product demand uncertainty. A factory production plan-replenishment management robust joint decision optimization method is provided by minimizing transportation cost and replenishment cost
