Introduction

Making decisions is a part of our daily lives. The major concern is that almost all decision problems have multiple, usually conflicting, criteria. Research on how to solve such problems has been enormous. Methodologies, as well as their applications, appear in professional journals of different disciplines. Diversified as such problems may be, they are broadly classified into two categories: (1) Multiple Attribute Decision Making (MADM) and (2) Multiple Objective Decision Making (MODM). From a practical viewpoint, MADM is associated with problems whose number of alternatives has been predetermined. The Decision Maker (DM) is to select/prioritize/rank a finite number of courses of action. On the other hand, MODM is not associated with problems in which the alternatives have been predetermined. The DM’s primary concern is to design a “most” promising alternative with respect to limited resources.
