Supply chain performance in the case of decentralized planning

摘要

Evaluating the performances of a Supply Chain is a hard task due to its decentralized structure and when one tries to take into account sustainable development issues. As a first step towards a realistic evaluation tool, in this paper, we provide a two-echelon supply chain model - a manufacturer and a 3PL provider - inspired from Jung, Chen & Jeong [4] which optimizes the economic criterion (costs) under a decentralized vision of the supply chain planning. We extended this model with a rolling planning horizon. The coordination between the actors is based on a negotiation process which exchanges the minimum information, i.e. the quantities needed. We evaluated this model with a cost structure inspired from the literature, several deterministic and stochastic demands and different rolling horizons. Results showed that decentralized planning is better than the centralized one in small rolling horizons. Sustainable considerations such as gas emission and securing resources will be discussed to extend this model.
