We propose in this paper the premises of an Interactive Decision Support System dedicated to the unidirectional tolerancing of mechanical assemblies. The foundation of our work is an efficient representation of a mechanical assembly based on graph theory. From this model, we can determine all the configurations of an assembly. An extended syntax for the functional constraints permits then to generate automatically all the tolerance chains. The final result is an automatically generated linear system of equations and inequations expressing the tolerance chains, as well as the existence of the configurations and coherence of the dimensioning scheme. This system can then be solved by an analysis or a synthesis approach.
