...Tianxiang Yao; Hong Gao Purpose Buffer operators can be utilized to improve the smooth degree of the raw data sequence, and to increase the simulation accuracy of the model. The purpose of this paper is to analyze the cause of increase in the simulation accuracy of the buffer operator. Design...

.... Originality/value It is a fundamental work to standardize all the definitions of terms for a new discipline. It is also propitious to spread the universal principles of grey system theory. Shocking disturbance sequence Sequence operator Three axioms Buffer operator General form Accumulating operator...

...Yong Wei; Xin‐hai Kong; Da‐hong Hu Purpose The purpose of this paper is to perfect the axiom systems of buffer operator via adding the axiom of invariable trend. Design/methodology/approach Based on the three axioms of buffer operator, for any given data sequence of system behavior and any set...

...Wen‐zhan Dai; Zi‐heng Wu; Ai‐ping Yang Purpose The purpose of this paper is to solve the problem existing in the forecast of impact disturbance grey system. Design/methodology/approach Under the axiomatic system of buffer operator in grey system theory, a novel kind of buffer operators...
