Figure 4: Membership functions for two inputs and one output in second-level fuzzy approach. (a) Four trapezoid membership functions for input 1 as low, medium, high, very high (b) Four trapezoid membership functions for input 2 as low, medium, high, very high (c) Three Gaussian membership functions for RF output as low, medium, and high
