Abstract:

In this paper, an optimization problem of collaborative planning in a supply chain is studied. Multiple periods, multiple products, multiple suppliers, multiple manufacturers, and multiple distribution centers are considered in mathematical modeling.The objectives include minimizing the cost of the supply chain and the completion time of its distribution plan.A hybrid approach combining integer programming (IP) and simulation is proposed to solve the problem.Computational experiments are conducted to show the validity of the proposed hybrid approach in solving the multiobjective productiondistribution model of a supply chain.

Key words: supply chain;collaborative planning;integer programming;simulation;multiple objective
