Abstract: A simulation of a job shop process based on a job shop model can be used to evaluate a particular schedule. A class of augmented Petri nets is introduced as a notation for microscopic deterministic job shop models which are well suited for short-term production control. It is shown how these Petri nets can be automatically transformed into CPM nets. These CPM nets represent the job shop schedule; they contain the full causal structure of the job shop process. An attempt is made to determine whether there is a fundamental limit of deterministic simulation of manufacturing facilities emerging out of chaos phenomena due to incomplete specification of deterministic models.
