This techniques uses the properties of the reachability matrix to find the most important and critical elements, loopst circuits etc. Also it gives some new ideas on a globaI methodology to build simulation models, which combines the traditional methods with some new one.esReachabilityComputer scienceMatrix (chemical analysis)MathematicsAlgorithmMatrices de alcanzabilidad, herramientas para la construcción y análisis de la estructura de modelos de simulaciónarticle
