Fuzzy linear fractional (FLF) models have a wide range of real-world applications. This kind of optimization problems have studied by many researchers from different perspectives. In this paper, we present a comparative study using complementary method and several formulas of ranking methods to formulate and solve (FLF) models. Based on this approach, we convert the (FLF) model into fuzzy linear (FL) model and then using the ranking functions, we transform from fuzzy form to crisp. Also, crisp linear model has solved using WIN QSB solver. In addition, an optimal solution for the fractional models is obtained based on several formulas of ranking methods. [ABSTRACT FROM AUTHOR]
