The aim of this article is further extending the linear programming techniques for multidimensional analysis of preference
(LINMAP) to develop a new methodology for solving multiattribute decision making (MADM) problems under Atanassov’s intuitionistic
fuzzy (IF) environments. The LINMAP only can deal with MADM problems in crisp environments. However, fuzziness is inherent
in decision data and decision making processes. In this methodology, Atanassov’s IF sets are used to describe fuzziness in
decision information and decision making processes by means of an Atanassov’s IF decision matrix. A Euclidean distance is
proposed to measure the difference between Atanassov’s IF sets. Consistency and inconsistency indices are defined on the basis
of preferences between alternatives given by the decision maker. Each alternative is assessed on the basis of its distance
to an Atanassov’s IF positive ideal solution (IFPIS) which is unknown a prior. The Atanassov’s IFPIS and the weights of attributes
are then estimated using a new linear programming model based upon the consistency and inconsistency indices defined. Finally,
the distance of each alternative to the Atanassov’s IFPIS can be calculated to determine the ranking order of all alternatives.
A numerical example is examined to demonstrate the implementation process of this methodology. Also it has been proved that
the methodology proposed in this article can deal with MADM problems under not only Atanassov’s IF environments but also both
fuzzy and crisp environments. 相似文献
