News from Rand Model Designer for Industry and Education

摘要

Rand Model Designer (http://www.mvstudium.com) is a modern tool for modeling and simulation of hierarchical multicomponent event-driven dynamical systems. It was demonstrated in the series of MIM-conferences, including MIM-2013 (Senichenkov Yu. (2013)). It utilizes the UML-based object-oriented Model Vision Language for designing dynamical and hybrid systems, using modification of State Machines - large-scale multicomponent systems, such as: control systems with "inputs-outputs", "physical" systems with "contacts-flows", and novel variable structure component systems, particularly "agent" systems. The recently launched tool "Visual Debugger" includes new modifications of numerical solvers for sparse systems, for instance it is now possible to reorder each solved system to block-triangular form with the help of Tarjan's algorithm in order to accelerate execution speed.
