This paper establishes the application of group decision-making idea on Wu-Leung multi-scale information systems from the perspective of multi-expert group decision-making. The transformation from GDM to MEGDM on a Wu-Leung MSIS through data unification is explained, along with the use of COPRAS method to obtain the optimal scheme. The effectiveness and feasibility of the proposed method are validated through numerical examples, demonstrating the superiority of the approach.
In this paper, we establish group decision-making (GDM) idea on Wu-Leung multi-scale information systems (Wu-Leung MSISs) from the perspective of multi-expert group decision-making (MEGDM). Based on the connection between a multi-expert group decision-making information system (MEGDMIS) and a Wu-Leung MSIS, we first use the idea of data unification to transform GDM on a Wu-Leung MSIS into MEGDM. We then construct a positive (and, respectively, a negative) ideal deviation distance information system. Subsequently, the complex proportional assessment (COPRAS) method is also used to obtain the optimal ranking scheme and the optimal alternative. Two numerical examples which can be formed respectively a Wu-Leung MSIS and an MEGDMIS are further employed to validate the effectiveness and feasibility of the proposed method. Comparative analysis and experimental examination are also presented to demonstrate the superiority of our approach. Finally, we summarize the link between MEGDM and GDM on Wu-Leung MSISs.
