MULTI-ECHELON PRODUCTION PLANNING PROCESS WITH NO TIME COORDINATION

The purpose of this paper is to study decentralized planning processes with no time coordination, performed within a whole supply chain. Distributed production and business units which compose the network, are considered as economically independent and autonomous in decision making, they define and update their production plans according to their own planning dynamic and strategy. Reactivity within these supply chains being quite dependent of this planning processes coordination, we try to assess the impact of this phenomenon on supply chain performance through a series of simulation, based on a generic linear programming model supporting the production, replenishment and delivery planning.
