M-LWDF [12]

${\gamma }_i\frac{{\mathrm{\chi }}_{i,\phi }^{\left(n\right)}}{R_{i,\text{ave}}^{\left(n\right)}}{H}_i^{\left(n\right)}$

M-LWDFQ [39]

${\gamma }_i\frac{{\mathrm{\chi }}_{i,\phi }^{\left(n\right)}}{R_{i,\text{ave}}^{\left(n\right)}}{N}_{Q_i}^{\left(n\right)}$

EXP-PF [12]

${\gamma }_i\frac{{\mathrm{\chi }}_{i,\phi }^{\left(n\right)}}{R_{i,\text{ave}}^{\left(n\right)}}exp\left(\frac{{\gamma }_i{H}_i^{\left(n\right)}-\overline{{\gamma }_i{H}_i^{\prime }}}{1+\sqrt{\overline{{\gamma }_i{H}_i^{\prime }}}}\right)$

EXP-PFQ [39]

${\gamma }_i\frac{{\mathrm{\chi }}_{i,\phi }^{\left(n\right)}}{R_{i,\text{ave}}^{\left(n\right)}}exp\left(\frac{{\gamma }_i{N}_{Q_i}^{\left(n\right)}-\overline{{\gamma }_i{N}_{Q_i}^{\left(n\right)}}}{1+\sqrt{\overline{{\gamma }_i{N}_{Q_i}^{\left(n\right)}}}}\right)$

LOG-RULE [15]

$b_{i}log\left[1.1+\left(a_i\frac{H_i^{\left(n\right)}}{H_{i,\text{max}}^{\left(n\right)}}\right)\right]\underset{i,\phi }{\overset{\left(n\right)}{\mathrm{\chi }}}$

EXP-RULE [15]

$b_i\ast \mathit{\text{exp}}\left[\frac{\left(a_i\frac{H_i^{\left(n\right)}}{H_{i,\text{max}}^{\left(n\right)}}\right)}{1+\sqrt{\overline{H_i^{\prime }}}}\right]{\mathrm{\chi }}_{i,\phi }^{\left(n\right)}$
