Exploring Potential of Expected Solution Point in Group Decision-Making
摘要
Multi-Criteria Group Decision Making (MCGDM) is often used to solve complex decision problems when it is required to aggregate the opinions of different decision-makers. MCGDM usually requires the evaluation of all alternatives by decision-makers or experts, which is a complex and time-consuming task in many cases. In this paper, we explore the potential of the Expected Solution Point (ESP) in group decision-making problems. For this purpose, we utilize the ESP - Characteristic Objects Method and propose a simple aggregation procedure for the SPOTIS method in order to work with several ESPs. The designed simulation case study shows that ESP-capable methods can be a viable alternative to the classic approach to group decision-making. An additional real-life case study on apartment selection highlights the usefulness of the proposed approach in the decision-making process.
