Abstract

Since growing complexity of software systems it is more difficult to meet demands of quality during the process of their design. To solve this problem with minimal loss this process is transferred onto more early stages of design, particularly onto the design of architecture. The architecture is treated as the set of components that encapsulates the logic of calculations, and connections that ensure the interaction between components and create their configuration. Since the architecture of software system is a high-level abstract model for representation of system structure and key properties, its selection grounds the insurance of quality for software system. In the paper the questions of evaluation of architecture quality on the set of quality attributes with Analytic Hierarchic Process (AHP) with applying of optimization algorithm for estimating of weights of alternatives are discussed. The conflicts between quality indices and trade-offs between them are analyzed.
