Modern requirements for visual tools for
modeling and simulation of complex
dynamical systems
 Object-Oriented approach (Object-Oriented Modeling)
 Universality (different types of mathematical models)
 Compliance with standard (for example UML)

Universality
Models with
«input/output»
components.
«causal»
different types of real dynamical systems and their mathematical models
Models with «contact/flow»
components.
«Physical»
Models with variable structure.

RMD’s distinctive features
 models with variable structure
 Lazy building of final hybrid automaton (composition of component hybrid
automata) for «physical» models
 Analyzing of type and structure of final systems of equations and using
suitable numerical method for each block if system has block low-triangular
form
 supplying information about numerical properties of solved system
 Automation of computer experiments
