Object-Oriented Memory Management in Devsim++

DEVSIM++ is an object-oriented simulation environment which implements Zeigler's modular, hierarchical DEVS formalism and associated abstract simulator concepts in C++. Due to the object-oriented modeling, size of simulation models in DEVSIM++ was bounded to memory size. This paper deals with implementation of an object-oriented memory management scheme as an extension of DEVSIM++. The scheme is based on concepts of persistence data in database management systems. Effectiveness and performance for the extended DEVSIM++ environment will be examined.
