*: Three additional combinations examined. See the text before the table: This paper used the same 18 combinations as [22]. In addition, three other combinations were examined for a total of 21 combinations. These additional combinations were included after an initial analysis of the data suggested that linear normalization was the best scaling method since it yielded the highest total scores regardless of the weighting method used.
