Fault treatment with net condition/event systems: a first approach

The paper presents a preliminary report on modeling parts of a modular production system, their dedicated controllers, and the appropriate methods of fault treatment on the level of net condition/event systems (NCES). To achieve practicability, NCES support a systematic and modular way of modeling more complex systems as well as concurrent and non-deterministic behavior which is highly beneficial for modeling and control of DES in failure situations as studies of existing methods show.
