The design scheme of software system involves multiple influencing factors,and the selection of software system design scheme is a complicated process of analysis and decision-making.In this article,a multi-attribute extension evaluation model is proposed to solve the decision problem in the selection process.Firstly,an evaluation indicators system of software system design scheme is established by providing the selection principles,and different types of evaluation indicators are normalized;then a corresponding calculation model for extension correlation degree is established;finally the optimal design scheme is obtained based on the extension correlation degree.
