Triangular Intuitionistic Fuzzy Linear Programming Problem with a New Ranking Method based on Correlation Coefficient

Received Date:06 February 2023, Accepted Date:11 August 2023, Published Date:04 December 2023


Objectives: The study discusses solving Triangular Intuitionistic Fuzzy Linear Programming Problem (TIFLPP) with triangular intuitionistic fuzzy coefficients and variables using triangular intuitionistic fuzzy simplex method. Method: The triangular intuitionistic fuzzy information given for the linear programming problem is preserved and not converted to crisp values while solving the problem which will represent the complete information of the decision problem. Findings: Several definitions and theorems are given to justify the stability of the triangular intuitionistic fuzzy simplex method. In addition to the existing ratio ranking method for finding the minimum ratio a new method of correlation coefficient is proposed for finding the minimum ratio in the simplex method. The procedure of the simplex method is explained through a numerical illustration. Novelty: The proposed new correlation coefficient of triangular intuitionistic fuzzy with graded mean integration representation and triangular intuitionistic fuzzy simplex method with defuzzification method are compared and suggestions are given based on the results obtained.
