ASPECT ORIENTED SIMULATION: A CASE STUDY WITH THE JAPROSIM FRAMEWORK

摘要

JAPROSIM is a free and open source discrete event simulation (DES) framework implemented in Java programming language for building discrete event simulation models. Separation of concerns (SOC) is one of the basic principles applied in design in order to improve software quality. Aspect oriented programming (AOP) has been proposed as a new technology that claims the application of this principle in the best way, through the modularisation of crosscutting concerns in additional units namely, aspects. In this paper, the main JAPROSIM crosscutting concerns are identified and adequate solutions using the AspecU language are presented. An empirical evaluation of the Aspect Oriented version of JAPROSIM is performed using the AOPmetrics tool. The results obtained show that the separation of JAPROSIM crosscutting concerns improves its quality attributes as modularity, understandability, maintainability, reusability, and testability.
