Abstract:
For the fast moving customer goods with a certain production and storage cycle, the coordinated production-inventory-distribution planning problem with multiple plants, multiple products and multiple customers under the deterministic demand are studied from the view of supply chain integration. A multi-period model of coordinated production-inventory-distribution planning problem is proposed using a mixed integer programming approach. This model effectively optimizes the production plan, inventory plan and distribution plan in the system simultaneously. To solve the model, a method based on tabu search algorithm is presented. Initial solutions are constructed by the designed sequential allocation method, candidate solutions are generated from neighborhood solutions of the improved 2-opt and 2-interchange, and then the implementation process of the algorithm is given. Finally, the results of the simulation examples prove that the tabu search algorithm is more robust than the hybrid genetic algorithm to solve this kind of problems, and can get a better solution.
