Abstract: A three-level supply chain composed of a supplier, a manufacturer and a distributor was considered, and the three members of the system are respectively called as first echelon, middle echelon and last echelon. Based on the existing supply chain model where the first and last echelons have capacity constraints, a new integrated lot-sizing model for the three-level supply chain was presented in which the middle echelon has capacity constraints. A new dynamic planning algorithm based on the mixed pull-push rules was proposed to determine the optimal material ordering batches in polynomial time. Some proven theorems show that the global optimal solution should be achieved. The proposed algorithm was explained via solving a simple problem.

Key words: integrated lot-sizing, capacity constraint, supply chain, dynamic programming
