Abstract:

With the continuous development of IT industry, users and experts have  paid more and more attention to software usability which determines the competitiveness and user satisfaction of software. So how to quantify and evaluate comprehensively the software usability is an important job. We propose a software usability evaluation method based on projection and the intuitionistic fuzzy theory. Firstly, we derive evaluation matrices based on user survey, and establish the ideal decision of evaluation matrices. Secondly, the projections of evaluation matrices on ideal decision are given based on group decision-making. Then, we make a ranking of evaluated software based on their projections. Finally, a practical evaluation example demonstrates the feasibility and practicability of the proposed method. The results show that the model is effective  for evaluating software quality.

Key words: quality evaluation, software usability, intuitionistic fuzzy information, projection, group decision-making
