Conceptual building blocks for modeling reconfiguration of component-based systems using Petri nets

This paper deals with the formal modeling of dynamically reconfigurable systems using Petri nets. Dynamic reconfiguration provides to a system the ability to change the behavior of its components at run-time without a system shut-down. By transferring the concepts of the coordination modeling language Paradigm to the setting of Petri nets a framework is obtained for the modeling of component-based systems. The framework then allows for reasoning about coordination of components on one level of abstraction and for analysis of reconfiguration on another level of abstraction. This factorization will be beneficial to subsequent formal assessment. A workers and scheduler example, the well-known dining philosophers, and a Festo MPS casestudy serve as illustrations.(c) 2022 Eindhoven University of Technology. Published by Elsevier Inc.
