Keywords: Pendant fuzzy number, Triangular Pendant fuzzy number, Trapezoidal Pendant fuzzy number, Pentagonal Pendant fuzzy number, Hexant fuzzy number, Triangular Hexant fuzzy number, Trapezoidal Hexant fuzzy number, Pentagonal Hexant fuzzy number, Octant fuzzy number, Triangular Octant fuzzy number, Trapezoidal Octant fuzzy number, Pentagonal Octant fuzzy number


The weaving machine’s reliability is assessed using newly introduced fuzzy numbers. The fuzzy numbers introduced in this study give a better method to improve the reliability than other techniques. Pendant Fuzzy Number, Hexant Fuzzy Number, and Octant Fuzzy Number are all introduced in this present study. Pendant Fuzzy Number, Hexant Fuzzy Number, and Octant Fuzzy Number,α-cuts are defined, as well as their mathematical operations. The numerical examples are utilised to conduct a comparative research of reliability using various Fuzzy Numbers, and their defuzzification is accomplished using various ways such as Signed Distance method, Graded Mean Integration Method and Centroid Method. The purpose of this study is to discover the most reliable value for a weaving machine.
