Discrete event simulation specification (DEVS) is a formalism designed to describe both discrete state and continuous state systems. It is a powerful abstract mathematical notation. However, until recently it lacked proper graphical representation, which made computer simulation of DEVS models a challenging issue. Unified modeling language (UML) is a multipurpose graphical modeling language, a ...
