An Approach Based on DEVS for Evaluating Quality Attributes

The present work provides a novel approach for the simulation of software at early stage of its development, using its architecture. For this purpose, DEVS formalism is used to introduce the discrete event simulation advantages in the context of software architecture. DEVS provides a modular and hierarchical way to build blocks in a simulation model, which fits naturally to architectural concepts. The proposal supports the transformation of architecture elements into simulation elements, decoupling the model from the simulator. The goal is to acquire quantitative information for evaluating the quality of the system at early stage, bringing support to make decisions.
