... and nonlinear membership functions, including linear, parabolic and hyperbolic, are employed to represent satisfaction levels. A numerical example from the agricultural sector is provided. Findings The approach effectively identifies an efficient compromise solution. Among the membership functions tested...

..., fuzzy numbers and their membership functions are developed to create a fuzzy hypothesis testing model using the derived confidence intervals. Findings The fuzzy testing method proposed in this study is grounded in the use of confidence intervals. It not only mitigates the risk of misjudgment caused...
