The equation is non-explicit; that is, the Structural Number ($SN$) cannot be easily isolated on one side of the equation. Solving for $SN$ requires iterative trial-and-error or complex logarithmic manipulation. Furthermore, because the Structural Number is a composite value derived from the thickness and material coefficients of the surface, base, and sub-base layers, engineers must balance these variables to achieve a cost-effective design. Performing these iterations by hand is time-consuming and prone to arithmetic errors, making computerized solutions a necessity. A very specific topic
