This paper proposes a new method for software architecture performance modeling. To achieve this ,it adds new calculus into stochastic process algebra(SPA in short),the developed SPA called extended stochastic process algebra (ESPA in short). By ESPA,performance evaluation and software architecture modeling can combine perfectly. It defines a few performance terms for software architecture using reward structure derived from ESPA. To explain the performance terms it also designs an experiment.展开更多

As is well known, it's better to improve the quality as early as possible, whichcan reduce the cost in following development and maintenance. Software architecture is the first activity from problemspace to software solution space, therefore, the decisions made during this process are significant to software quality.Software architecture quality evaluation analyzes and predicts qualityfrom architecture level, helping make proper ar-chitectural decisions and detecting derivation during following development. This paper summarizes the researches inthis area, introducing the purpose, content, state of the art and application status, analyzing the difficulties and dis-cussing the future directions.展开更多
