Abstract

Assignment problem is very often used in solving problems of engineering and management science. In this paper, trapezoidal fuzzy numbers are considered which are more realistic and general in nature. The fuzzy assignment problem has been transformed into crisp assignment problem in the LPP form solved by using LINGO 9.0 and the results were compared with average method. Subject classification: Fuzzy Logic- 03B52
Keywords. Fuzzy sets, fuzzy numbers, fuzzy assignment problem , fuzzy ranking, hungerian method
