The Concepts of the Relative Width of Grey Common Ratio and the Absolute Width of Grey Development Coefficient and Its Application of the Prior Check in Grey Modeling

摘要

The concepts and projection method of the relative width of grey common ratio and the absolute width of grey development coefficient are presented in this paper. The new method of prior check in grey modeling is also given in this paper. Some examples are also given to show that all these methods are possibl e and available.
