Study on trustworthy software development risk factors clustering based on grey correlation model

For the grey correlation model in grey clustering method, correlation model of interval number is put forward in this paper. From the point of the principle of gray correlation, in order to avoid the distance between interval numbers, we calculate the correlation coefficient of two interval numbers directly. At last, we study the software development risk factors clustering based on correlation model of Interval number. Case study presented in this paper verifies effectiveness and practicality of clustering method based on correlation model of interval number.
