Influence in Group Decision Making
Group decision making is becoming a common activity in many industrial settings, and a number of methods for assisting are regularly proposed. These may be theoretical, such as most of the MCDM approaches, or technologically based computer systems. However nearly all of them do not consider the individual influences that are brought to bear on the group decision. This paper presents a case study where this aspect is investigated using a method of psychological profiling. The experimental results show that the make-up of the group of decision makers may have a dramatic impact on the final decision. Although only a single small case study, the outcome suggests that group characteristics may have a direct impact on the use of MCDM models. It may be a fruitful avenue of future research in group decision making.
