Short description This text outlines the considerable and promising research that is being conducted to counter the problems of uncertainty surrounding the methods used to approach these new applications in the field of modelling and simulation. The book aims to stimulate the reader into seeking out new tools for modelling and simulation, using examples such as differential inclusions, semi-discrete events, and a possible matric structure in the space of models.
