Abstract:
Decision analysis is primarily a prescriptive discipline, built upon normative and
descriptive foundations. In all decision making situations, an individual decision maker (DM)
arrive at any decision through some conscious and unconscious processes of their brain. In a
conscious decision making situation, the DM must have complete information about the
problem, the criteria, the alternatives, the methods and their consequences before arriving at
any decision. This scenario is known as informed decision making situation. Since, all the
discrete alternative multi-criteria decision making (MCDM) methods relies on the preferences
of the DM on objective values of the alternatives, the role of the DM is very crucial. This
necessitates that the MCDM methods used by the DM in an informed decision making
situation to solve a multi-criteria decision (MCD) problems must conform to the cognitive
capabilities and descriptive realities of the DM.
