Optimization of fuzzy assignment model with triangular fuzzy numbers using Robust Ranking technique

Assignment problem is the special case of linear programming allocation problem. Consider the situation of assigning m jobs to n machines. The cost of assigning the jobs i = 1,2,...., m to a machine j = 1,2,..., n is Cij. In this paper Cij has been consider to be triangular number denoted by Cij which are more precise in nature. Robust ranking method has been used for ranking the fuzzy numbers. The Hungarian (One’s assignment) method has been applied to solve the fuzzy assignment problem. An illustrative numerical example is provided to demonstrate the effectiveness of the fuzzy assignment problems.
