Dynamic Reconfiguration in DEVS Component-based Modeling and Simulation

Dynamic reconfiguration refers to the ability of a system to dynamically change its structure and interface according to different situations. It provides component-based modeling and simulation environments with powerful modeling capability and the extra flexibility to design and analyze complex systems. In this paper, we discuss dynamic reconfiguration, specifically the variable structure and interface change capability, in DEVS modeling and simulation environments. The operations of structure and interface changes are discussed and their operation boundaries are defined. Three examples are given to illustrate the role of dynamic reconfiguration and how it can be used to model and design adaptive complex systems. Principles for the implementation of dynamic reconfiguration are also presented and illustrated in the DEVSJAVA modeling and simulation environment.
