Problems solved by technology

[0009] The disadvantage of the above evaluation method is that the evaluation of the quality characteristics by the evaluation experts is carried out according to the fixed evaluation level shown in the following formula
[0012] Therefore, this deficiency makes the evaluation results of the existing quality evaluation methods for software evaluation not scientific, objective, fair, and poor in accuracy.

Embodiment Construction

[0069] Such as figure 1 Shown, the present invention is the software quality comprehensive evaluation method of cloud model and fuzzy soft set, at first user provides software set S={s to be evaluated 1 ,s 2 ,...,s q} and evaluation index set C={c 1 ,c 2 ,...,c n}; Then each evaluation expert gives a personal evaluation index set And give the qualitative evaluation matrix of natural language description Then, the cloud model is used to transform the qualitative evaluation of experts into quantitative evaluation, and then the fuzzy soft set is used to fuse the quantitative evaluation of all evaluation experts to obtain the final evaluation result. The specific steps are as follows:

[0070] Step 1: The user provides the software set to be evaluated S={s 1 ,s 2 ,...,s q}, evaluation index set C={c 1 ,c 2 ,...,c n} and evaluation expert set Ex={ex 1 ,ex 2 ,...,ex m};

[0071] The quality evaluation system of the present invention is the same as the prior art, s...

Abstract

The invention discloses a comprehensive software quality evaluation method based on a cloud model and fuzzy aggregation. Firstly, judging experts in different fields make natural language evaluation of quality characteristics, then conversion from qualitative evaluation to quantitative evaluation is performed on evaluation information on the basis of the cloud model, finally, quantitative evaluation information of all the experts is aggregated by using fuzzy soft sets, and a comprehensive judgment result is obtained. With the adoption of the method, conversion from natural language qualitative evaluation values to quantitative evaluation values is realized easily, knowledge and experience of the experts in different fields are fully considered, and different preferences of the experts in all fields are considered. The software quality evaluation method is scientific, just, objective and high in accuracy and can be used for guiding users to purchase and use software and guiding software developers to develop high-quality software products.

Description

technical field [0001] The invention relates to the field of software evaluation methods, in particular to a software quality comprehensive evaluation method based on cloud models and fuzzy aggregation. Background technique [0002] With the increasing popularity of software product applications, the market's requirements for software product quality continue to increase. How to evaluate the quality of software has become the most concerned issue for users, software engineers and managers of software organizations [5,6] . Because the evaluation results of software quality can not only guide users to purchase and use software, but also guide software developers to develop high-quality software products. At present, the research on software quality evaluation mainly focuses on two aspects: [0003] (1) Analytic hierarchy process (AHP): The main idea is to decompose various factors affecting software quality according to a certain standard to form different levels, and then ...
