...Ye Li; Sandang Guo; Juan Li Purpose The purpose of this paper is to construct a prediction model of three-parameter interval grey number based on kernel and double information domains to expand the modeling object of grey prediction model from interval grey number to three-parameter interval grey...

...Lili Qian; Sifeng Liu; Zhigeng Fang Purpose The purpose of this paper is to advance a new grey risky multi-attribute decision-making (RMADM) method from the perspective of regret aversion, which is based on the general grey numbers (GGNs) taking the form of kernel and degree of greyness. Design...

...San-dang Guo; Sifeng Liu; Zhigeng Fang Purpose The purpose of this paper is to establish the algorithm rules of the interval grey numbers and propose a new ranking method of the interval grey numbers. Design/methodology/approach The definitions of “kernels” based on lower measure, upper...

... and 1. Kernel Grey number Interval grey number General grey number Degree of greyness Simplified form Synthesis axiom Operation rules Such a number instead of its range whose exact value is unknown is referred to as a grey number. Grey number is the basic “unit” or “cell” of grey...

... axiom, operation rules of general grey numbers and a new algebraic system for general grey numbers are built based on the “kernel” and the degree of greyness of grey numbers. Findings Up to now, the operation of general grey numbers has been transformed to operation of real numbers; thus...
