This paper introduces basic conception and numerical characteristics of cloud model,analyzes normal cloud model and cloud generator,illustrates the application of cloud model in enterprise quality cost prediction,and lists a concrete example to prove that the implantation of this method can offer powerful support to improve enterprise quality and lower cost and risk.

【Abstract】 We Propose to generate drop-motion vector using cloud generator.

A method of realizing intelligent control with membership cloud generators is mainly presented in this paper.

The method of describing membership clouds by using digital characteristics and the mathematics model of normal membership clouds are given, and the implementation techniques and application areas of membership cloud generators are discussed in this paper.

Based on the theory of probability statistics, the authors make the more thorough research to the property of normal cloud, and construct a new algorithm of backward cloud which is more precise than the old one.
