چکیده
|
In this paper, a multi-objective assignment problem with fuzzy parameters (fmoasp) is introduced. these fuzzy parameters are characterized by an (𝛾,𝛿) interval-valued fuzzy numbers instead of fuzzy numbers. the signed distance ranking of (𝛾,𝛿) interval- valued fuzzy numbers of the parameters are not random but bear well-defined relationship to one another. a new approach namely, optimal flowing method is proposed to obtain the ideal and the set of all fuzzy efficient solutions for the problem. a numerical example is given to demonstrate the computational efficiency of the proposed approach.
