Table 2 Optimized method of calculating membership
Kn | Incremental factor | Descending factor |
|---|---|---|
\(u_{i} < k^{\prime}_{1}\) | \(Q_{i} { = }\frac{{k^{\prime}_{1} - u_{i} }}{{V_{ \hbox{max} } }}\) | \(Q_{i} = \frac{{u_{i} - \,k^{\prime}_{1} }}{{V_{\hbox{max} } }}\) |
\(u_{i} < k^{\prime}_{5}\) | \(Q_{i} = \frac{{u_{i} - \,k^{\prime}_{5} }}{{V_{\hbox{max} } }}\) | \(Q_{i} = \frac{{k^{\prime}_{1} - u_{i} }}{{V_{\hbox{max} } }}\) |
