On Quadratic Membership Functions in Solving Assignment Problem under Fuzzy Environment

摘要

In this article, a bell shaped fuzzy number called piece wise quadratic fuzzy number (PQFN) whose membership function is quadratic in nature is used. New arithmetic operations of the fuzzy number are also utilized. Fuzzy Hungarian method is proposed to find the optimal solution in terms of fuzzy numbers and verified its solution in the nature of quadratic membership functions. A relevant numerical example is also included.
