Conceptual Building Blocks for Modeling Reconfiguration of
Component-Based Systems Using Petri Nets 
Yousra Hafidi & Erik de Vink

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.
