Construction and Application of a New kind of Strengthening Buffer Operator Based on the Convex (Concave ) Function and Geometic Meaning

摘要

In this paper a new kind of strengthening buffer operator is proposed based on the convex and concave functions and a numerical example is used to demonstrate the proposed method.The designed procedure includes complying with the existing buffer operator of grey system theory axiom system, using relevant properties of convex (concave) function that the image is always in the bottom of connecting two points, and combining with the geometric meaning of the definite integral.
