A kind of new weakening buffer operators and their applications

By using grey system theories,based on the present theories of buffer operators and some already existed weakening buffer operators,some new weakening buffer operators are established,which have the universality and practicability.Meanwhile,the characters and the inherent relation among them are studied.The problem of some contradictions between quantitative analysis and qualitative analysis existing in pretreatment for vibration data sequences is resolved effectively.An example shows that the kind of new weakening buffer operators increase the forecast precision of data forecast model remarkably.
