...Sandang Guo; Liuzhen Guan; Qian Li; Jing Jia Purpose Considering the bounded confidence of decision-makers (DMs), a new grey multi-criteria group consensus decision-making (GMCGCDM) model is established by using interval grey number (IGN), cobweb model, social network analysis (SNA) and consensus...

...Ye Li; Yuanping Ding; Yaqian Jing; Sandang Guo Purpose The purpose of this paper is to construct an interval grey number NGM(1,1) direct prediction model (abbreviated as IGNGM(1,1)), which need not transform interval grey numbers sequences into real number sequences, and the Markov model is used...

... performance indicator for the final decision. Inventory routing problem Demand uncertainty Grey systems theory Interval grey numbers The paper is organized as follows: in section 2 , a related literature review for the IRP and grey programming models is provided; also, a biobjective IRP model...

...Davood Darvishi; Jeffrey Forrest; Sifeng Liu Purpose Ranking and comparing grey numbers represent a very important decision-making procedure in any given grey environment. The purpose of this paper is to study the existing approaches of ordering interval grey numbers in the context of decision...

...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...
