The MULTIMOORA method is developed using interval numbers based on fuzzy logic concept
and a novel preference technique to deal with complex uncertain problems. By utilizing
the fuzzy concept and considering relative weights for attributes, assessment values are obtained
for subordinate parts of the interval weighted MULTIMOORA. We suggest an interval
comparison matrix to calculate aggregate preference as an index to find the interval maximal
objective reference point vector and rank the assessment values of the interval weighted ratio
system and the full multiplicative form. The theory of dominance is employed to consolidate
the subordinate ranks into the final ranking. Because of the reasonable assumption of alternative
ratings as interval numbers in industrial problems and straightforward mathematics
of the interval weighted MULTIMOORA, the proposed method can be effectively utilized by
decision makers. A case study regarding materials selection of power gears is solved using the
proposed method. Our final ranking for the practical case is verified with two interval-based
and several crisp MADM methods.
