Abstract

It is critical to get good activity metrics of discrete-event system specification (DEVS) models before and during their simulation (called analytic or simulation activity corresponding to application before or during simulation), we propose in this chapter a way to perform profiling of DEVS models. Having a means to compute a priori analytic activity of components may be worth when simulating a model (or parts of it) for the first time. During the simulation, analytic activity can be corrected using simulation-based measurements. In this chapter, we introduce several analytic and simulation-based activity metrics, which have been implemented through a plug-in of the DEVSimPy (DEVS Simulator in Python language) environment and applied to two case studies involving complex atomic and coupled DEVS models.
