A naïve approach for solving MCDM problems: the GUESS method

We present a simple multiple criteria decision making solution technique called the GUESS method. This method has been used in MCDM experiments where different solution methods have been compared. The GUESS method is an interactive solution method designed to be used with continuous multiple criteria decision problems. It is based on a class of solution methods called reference point methods whereby the decision maker generates a sequence of solutions based on a sequence of guesses or aspiration vectors. In this paper we explain the basic concepts of the GUESS method and describe the algorithm of the solution method. An illustrative example is provided, along with a discussion of the method from a behavioural decision making perspective.
