• FUZZY RANKING METHOD TO ASSIGNMENT PROBLEM WITH FUZZY COSTS

Surapati Pramanik*, Pranab Biswas**

Abstract


This paper presents solution methodology for assignment problem with fuzzy cost. The fuzzy costs are considered as trapezoidal fuzzy numbers. Ranking method (introduced by S. Abbasbandy and T. Hajjary, 2009) has been used for ranking the trapezoidal fuzzy numbers. Hungarian method is extended to solve this type of fuzzy assignment problem. Two Numerical examples are solved to check the validity of the proposed method.

Keywords


Assignment problem, Fuzzy assignment problem, Hungarian method, Trapezoidal fuzzy number.
