Abstract
For years decision makers have been faced with making decisions in the presence of multiple alternatives and conflicting criteria. Until the development of Multiple Attribute Decision-Making (MADM) techniques, decision makers were forced to rely solely upon their intuition to make complicated decisions. Now, however, MADM techniques can be used to either support intuitive judgements or provide the necessary "reasonable doubt" to force decision makers to more thoroughly explore the decisions in question.
MADM techniques, however, are diverse and situation dependent (i.e. some techniques are appropriate for certain situations, some are not). Techniques used by some analysts have been criticized by other analysts. This was certainly the case during a recent study which used a specific MADM technique to select an automated information system from among several alternative systems.
To investigate the merits of the objections to the previous study, this paper presented an alternate MADM solution strategy to determine if another MADM technique would alter the final recommendation. Using the data of the previous study, the strategy consisted of using dominance to screen the alternatives, the eigenvector method (developed by Saaty [35,37]) to weight the attributes, and finally, simple additive weighting to select a preferred alternative.
The alternate strategy was applied using the data from the previous study. The results were the same as those of the previous study - Alts was the preferred alternative. Although the alternate strategy was more mathematically oriented than that of the previous study, the same alternative was recommended. Therefore, this study supports the results of the previous study.
