A Quality Based Method to Analyze Software Architectures

In order to produce and develop a software system, it is necessary to have a method of choosing a suitable software architecture which satisfies the required quality attributes and maintains a trade-off between sometimes conflicting ones. Each software architecture includes a set of design decisions for each of which there are various alternatives, satisfying the quality attributes differently. At the same time various stakeholders with various quality goals participate in decision-making. In this paper a numerical method is proposed that based on the quality attributes selects the suitable software architecture for a certain software.
