Extension of Grey Random Model based on Cloud Model and Its Application in Software Evaluation of Users

摘要

—In order to overcome the shortcoming of ablation function in dealing with the complex problem in classic gray decision, this paper studies on improved ablation function based on the gray cloud model and its applicant in the gray decision. At first the classic ablation function and its shortcoming are given. Then the gray cloud model integrating gray with randomcity is proposed. The numerical character of gray cloud and the method of creating grey model with normal school and are given. Gray number ablation model based on gray cloud is used to replace of the classic ablation function. At last the applicant of ablation model of gray number based on the gray cloud with normal school in the gray clustering decision making is given. And the application case is provided to estimate the validity of method.
