We apply DS evidence theory to software usability evaluation and establish the software usability evaluation index system in view of the education resources, and a software usability evaluation method based on DS evidence reasoning is proposed.
(1) A software usability evaluation index system of the educational resources software based on the ISO/IEC25000 series standards is introduced, which fully considers the characteristics of the educational resources software and the characteristics of the target user.
The most important aspect of software usability evaluation is to find availability of the metric and to integrate the metric and subattributes evaluation into software availability .
(1) Establishing the evaluation index system of educational resources software usability based on multidimensional attribute, and the value of metric element is obtained
The ISO/IEC25000:2014  is an important international standard for software quality and software evaluation, and a quantitative evaluation method for software usability is provided in the standard.
To verify the effect of proposed software usability evaluation model for educational resources software, we used the proposed hybrid intelligent optimization model to evaluate the usability of the convenient educational resources management platform (http://188.8.131.52:8080/), which was developed by our software team in 2015.
Firstly, software usability interval model is constructed by the maximum values and the minimum values of the historical sample data, which are evaluated by the experts.
Suppose that the educational resources software usability measurement value of secondary indexes (learnability, memorability, operability, and controllability) is 0.95, 0.91, 0.89, and 0.95, respectively.
This paper proposes a novel educational resource software usability assessment method.
