In any real-life problem, decision-making plays a very important role. It is always observable that uncertainty, hesitation, vagueness, etc. are involved in real-life situations. The existence of such factors increases the difficulty for the decision maker(s) to decide the accurate/precise, crisp value of parameters involved in the specific problem. In the present study, the uncertainty included in the transportation problem is dealt with by the proposed method based on the derived accuracy function. The function is derived using the centroid method and is further used to convert the fuzzy number into a crisp value in the proposed approach. The applicability and validity are presented with the numerical illustration. The superiority and comparative study are shown by applying it to the real-life transportation problem as a case study of Dinanagar city, India.
