Component Based Software Architecture Models for Quality Attributes

Software quality refers to two related but distinct notions that exist wherever quality is defined in a business context such as performance or reliability, are crucial for the success of a software system and largely influenced by the software architecture. Their quantitative prediction supports systematic, goal-oriented software design and forms a base of an engineering approach to software design. Researchers have proposed numerous approaches to predict a quality property based on a software architecture models. Even with a given functional design, many degrees of freedom in the software architecture (e.g. component deployment or server configuration) span a large design space. In a method and tool to improve component-based software architectures (CBA) by searching the design space using meta heuristics. The method relies on existing performance and reliability prediction methods to evaluate candidate architectures.
