1 Introduction
With software functional requirements and increasing level of improvement, software systems become increasingly complex and large. Therefore, what are bound to increase are the loopholes and flaws. In the development process, the developer will bring some risk of loss, in the course, users can also assume that failure to bring the risk of loss. The international software design and use of defects as a result of accidents and loss are common. Thus, credibility in use and the process of software development have become a widespread international concern. Analysis of credibility in the process of software development and use is particularly important.
There are many researchers who have researched risk in software. [2] Chittister and Haimes (1993) studied software development risk using holographic modeling from function, source and process three dimensions. [10] Bannerman (2008) studied risk and risk management in software from a reassessment point of view. [4] Huang et al. (2008) presented a software reliability index model based on Bayesian network. [11] Shi et al. (2010) proposed a fuzzy AHP and fuzzy multi-attribute decision making model for assessment of the model. [5] Lang et al. (2010) established software credible evidence reference model. [1] Cheng et al. (2010) analyzed China's credibility of software industry and puts forward strategies for promoting China's software industry development. [12] Houmb et al. (2010) studied a quantifying method to security risk level from CVSS estimates of frequency and impact.
Grey cluster is an important part of grey system theory, and it is used in assessment and decision analysis commonly. Grey whiting weight function cluster, which is used widely, is a kind of grey cluster. Determination of the whitening weight function is mainly based on expertise's experience, and there is a little existing research on whitening weight function. [15] Wang (1987) proposed a new grey relational analysis mode (B-mode). [14] Tang (1996) put forward experience value method and mean value method, and examples ware used to prove that average method is superior to experience. Experience value method's downside is it can be influenced by human factors. [16] Zhang and Liu (2007) examined the turning point in albino...
