Abstract This study demonstrated the effectiveness of fuzzy method in decision-making and recommends the integration of fuzzy methods in decision-making in production, transportation, power production and distribution and utility main- tenance in Nigeria companies. Keywords: Fuzzy set, Fuzzy linear programming, Fuzzy constraints, Fuzzy optimization. 1 Introduction Linear Programming (LP), an important tool in operations research, has developed over the years in solving management problems [13]. It is in two forms: classical and fuzzy linear programming. It takes various linear inequalities relating to the situation being considered and finds the best value obtainable under that situation. * Centre for Petroleum Economics, Energy and Law (University of Ibadan, Ibadan, Nigeria), ezemiraclekasie@gmail.com. † Department of Mathematics, Faculty of Science (University of Ibadan, Ibadan, Nigeria), babtu2001@yahoo.com. 29
