Integrating system performance engineering into MASCOT methodology through discrete-event simulation

Abstract

Software design methodologies are incorporating non functional features on design system descriptions. MASCOT which has been a traditional design methodology for European defence companies has no performance extension. In this paper we present a set of performance annotations to the MASCOT methodology, called MASCOTime. These annotations are extending the MDL (MASCOT Description Language) design components transparently. Thus, in order to evaluate the performance of the annotated software designs, a discrete-event simulator prototype is also introduced. The prototype has been implemented with Java objects which are isomorphic to the MASCOTime components. Several examples of MASCOTime models and simulation results are also shown. © Springer-Verlag 2004.
