Abstract: | In this paper, we investigate and extend a method of selecting
among a set of concepts or alternatives using multiple,
potentially conflicting criteria. This method, called the
Hypothetical Equivalents and Inequivalents Method (HEIM),
has been shown to avoid the many pitfalls of already existing
methods for such problems, such as pair-wise comparison,
ranking methods, rating methods, and weighted sum
approaches. The existence of multiple optimal sets of attribute
weights based on a set of stated preferences is investigated.
Using simple visualization techniques, we show that there is a
range of weights that satisfy the constraints of HEIM.
Depending on the attribute weights used, multiple possible
alternative winners could exist. The visualization techniques,
coupled with an indifference point analysis, are then used to
understand the robustness of the solution obtained and
determine the appropriate additional constraints necessary to
identify a single robust optimal alternative |
