For Selection of a Site for Nuclear Waste Disposal Using $\text { Score }_{i}=\frac{x_{i}-x_{\min }}{x_{\max }-x_{\min }}$

Multiple Choice

For selection of a site for nuclear waste disposal using MCA, we use the proximity to highly populated areas as one of the criteria. The proximity is measured in terms of distance. Suppose x_min is the shortest distance from the proposed disposal sites to the highly populated areas in the study area, x_max is the longest distance from the proposed disposal sites to the highly populated areas, and x_i is the shortest distance from the proposed disposal site i to the highly populated areas. Using the score range procedure, which of the following equations should you use to standardise the criterion scores?

A) $\text { Score }_{i}=\frac{x_{i}-x_{\min }}{x_{\max }-x_{\min }}$
B) $\text { Score }_{i}=\frac{x_{\max }-x_{i}}{x_{\max }-x_{\min }}$
C) $\operatorname{Score}_{i}=\frac{x_{i}}{x_{\max }}$
D) $\operatorname{SCOre}_{i}=\frac{x_{\mathrm{min}}}{x_{i}}$
