Use the approach given in Equation 13.9, in which the score for an alternative is the sum of the products of the weight for each evaluation criterion and the relative score or value for each criterion. First, the input values are to be used to calculate the relative scores, Vij. For example, to evaluate the performance measure for the criterion mobility, the travel time of each alternative must be calculated. For example, for alternative 1, the travel time is:
The relative scores, Vij, can then be calculated. For example, for the evaluation criterion mobility, the travel time of the shortest travel time alternative divided by travel time of alternative i must be determined for each alternative. The shortest travel time is for alternative 2, at 0.1633 hours. For alternative 1, the travel time is 0.1867 hr, and the relative score is 0.1633/0.1867 = 0.8750.
The scores for each alternative i can then be found by finding the products of the
weights (Kj) and relative scores (Vij) and then summing these products.
The recommended alternative is Alternative 1, with a score of 85.03, the highest score among the alternatives.
