基于投影的软件易用性评价方法

A projection-based estimation approach to software usability

随着IT行业的不断发展,软件的易用性越来越受到用户和专家的关注与重视。如何科学地量化软件产品的易用性,进而对产品质量进行综合地测评,决定了软件产品的竞争力和用户的满意度。针对软件的易用性,提出了一种基于投影和直觉模糊理论的评价方法。首先,依据用户调查得到的信息,给出评价软件易用性的直觉模糊评价矩阵,并在此基础上建立了评价矩阵的理想决策。其次,借助群决策的框架,给出评价矩阵到理想决策上的投影。然后,基于投影给出测评软件的优劣序。最后,用一个测评实例展示出本方法的有效性和实用性。结果表明,本文提出的模型是一种软件质量综合评价的有效方法。

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 soft- ware. 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 de- cision-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.
