摘要：In this paper the authors are interested in passive robustness of manufacturing job-shops with time constraints and particularly in the passive robustness facing advance time disturbances. The operation times are included between a minimum and a maximum value. P-time Petri nets are used for modeling. An algorithm allowing the computation of an advance passive robustness margin is elaborated relying on a study of the available local robustness at the synchronization transition of a mono-synchronized subpath. Moreover, a lemma is stated regarding constraints violation where the margin is calculated. The occurrence of a time disturbance respecting both the lemma conditions and the algorithm margin does not involve any constraints violation. The established results are illustrated step by step on examples of a given workshop.
