Aggregated behaviors for planning processes simulation and characterization of the dynamics in a supply chain

Abstract : Decision making in supply chain context can be a difficult process due to the complexity of the models used to support this decision. We present first results of research project whom the target is to support collaboration decisions. The present study focuses on modelling the dynamics of the customer's planning and market behaviors. We propose an aggregated model of these behaviours and associated impacts on requirement plans. In order to analyze static and dynamic aspect of plan generation, a set of indicators is proposed that evaluate static aspect and mainly dynamics of requirement planning. Model and indicators utilizations are illustrated through an industrial case study.
