An Object Oriented Framework Formodeling and Simulation of Variablestructure

This paper introduces an approach for object-oriented modeling of modular-hierarchical systems that supports inheritance and polymorphic operations. The key ideas of the approach are motivated by requirements that arise from modeling and simulation of variable structure systems. A novel deenition of modular-hierarchical systems with discrete structural changes is given before the modeling approach and the basic concept of a simulator realization are presented. Finally , an application of the approach to time variant systems is demonstrated.
