Abstract

Exploiting features of the OMT-based object-oriented approach, the paper presents a method for performance assessment early in the lifecycle, and before the design phase. To this end the actor-event graphs (AEG) formalism is presented that provides an intermediate model between specification models and software performance models. The AEG formalism unifies performance relevant information contained in various OMT models (class diagrams, interaction diagrams, state transition diagrams) into a single representation. Two algorithms deriving AEGs from different analysis results are described and the effectiveness of the approach is illustrated by an application case study
