In high competitive industrial context where the collaborative partnership becomes a strategic answer to face the increased market requirements, supply contract gradually appears to be a key element in supply chain management. The contribution of this thesis is twofold. In one hand, methodological approach aims at providing deciders with contracting framework support that links clause, risk and performance in order to define, by instrumented approach, relevant clauses to commit in adequacy with industrial context and supplying relationship. In the other hand, planning model including contractual constraints and simulation platform are developed. Two types of supply contracts (commitments on quantities per period and commitments on quantities per horizon) are simulated, highlighting their impact on local performance (partner view) and global performance (supply chain view).
