Study of Linear Fractional Programming Problems By Using Ratio Ranking Method

This article presents the study of linear fractional programming (LFP) problems under intuitionistic fuzzy setting. The objective of this paper is to solve LFP problems by using ratio ranking method of triangular intuitionistic fuzzy number(TIFN). The problem is considered as a fully fuzzy linear fractional programming (FFLFP) problem where the variables and parameters both are characterized by TIFN. To find the optimal solution of the problem, we have used simplex method where the steps are represented by a flowchart diagram. One numerical example is solved to illustrate the proposed methodology.
