Due to the enlargement and complexity of software systems and the need for maintenance and update, success of systems depends strongly on their architecture. Software architecture has been a key element in software development process in two past decades. Therefore, choosing the correct architecture is a critical issue in software engineering domain, with respect to the extremely extension of architecture-driven designs. Moreover, software architecture selection is a multi-criteria decision-making problem in which different goals and objectives should be considered In this paper, a Decision Support System (DSS) has been designed which provides software architects with more precise and suitable decisions in architecture styles selection. The DSS uses fuzzy inference to support decisions of software architects and exploits properties of styles in the best way while making decisions.
