ROBUST DYNAMIC CONTROL OF MULTI-PRODUCT JOB-SHOPS

This paper deals with the robustness of Dynamic Discrete Event Systems including time interval constraints. It recalls to mind a method to compute the passive robustness by the decomposition of the P-time Petri Net model into four sets. The computing algorithm of a lower bound for the maximal time disturbances allowed on a given point is presented. The main contribution concerns the active robustness. An algorithm providing a global robustness new lower bound is introduced.
