A pragmatic approach for precedence graph generation

Presents a pragmatic-approach for a systematic product structure analysis and precedence graph determination. Both tasks are performed on a unique product model based on the liaison diagram formalism and designed to deal with variants. A simple enrichment of the liaison description allows us to make the proposed approach easy to implement and considerably reduces the amount of information to be introduced in the model. All the concepts presented in the paper are applied to an electromechanical product (safety switch). This work is part of a project related to the global interactive product and assembly line design problem (CISAL project).
