Abstract: This paper,based on the coordination and integration of the supply chain,proposes the bi-level programming model for the production planning of the two-echelon distribution network with the multi-plants and multi-distributors.It considers the information sharing between manufacturers and distributors to make the cost of the whole supply chain minimum,and at the same time a heuristics algorithm is given.At last,the application of the model and its algorithm are illustrated with a practical example.

Key words: distributed plants, supply chain, distribution network, production planning, bi-level programming
