Localization of Time Disturbances in Tolerant Multi-product Job-shops Without Assembling Tasks

This paper deals with time disturbances localization in critical time manufacturing job-shops. In such systems operation times are included between a minimum and a maximum value. Controlled P-time Petri nets are used for modeling. Some definitions and a series of lemmas are quoted in order to build a theory dealing with such problem. They are illustrated step by step on examples of a given workshop.
