Group decision making based on incomplete intuitionistic multiplicative preference relations

摘要: The incomplete intuitionistic multiplicative preference relation (incomplete IMPR), whose elements are numbers, is suitable for describing the asymmetric information and allows decision makers to skip some dubious comparisons flexibly. In this paper, concept of IMPR introduced approaches group making (GDM) with IMPRs investigated. To do this, consistency property an discussed, especially acceptable consistency. Based on it, two complement all missing presented, which involve steps: "estimating step" "adjusting step". Firstly, a geometric mean method given estimating initial values elements. Then different methods developed adjusting those values: one adopts local optimization models, time-saving; other utilizes iterative can operate whole process conveniently After that, procedures GDM proposed illustrated by problem venue selection communication drills. Compared previous work, have better performance computational complexity speed processing large amount data.
