Set-theoretical expression and implementation of systems with dynamical structural change

Abstract

This article shows a mechanism for the set-theoretical expression and the implementation of systems with dynamical structural change. The current 4th generation systems development methodology does not assume that systems change its structure on real time basis. This article tries to extend the methodology for systems that are out of its targets so far. It is shown that this type of systems can be treated with a simple extension of the model description language (MDL) if they hold a certain property.
