Eij: The value of Ci from Ai
Wj: The weight of a factor j
Nij: The normalization value of Eij
Vij: The weighted normalized performance rating
V+: The best solution(value)
V-: The worst solution(value)
s t+: The distance of V+
s t+: The distance of V-
vt+: The final preference value
Firstly, normalize the value of the factorj of a routei as shown in the
Equation (3).
Apply the weights of factors to the normalized matrix to get the weighted
normalized performance rating as shown in the Equation (4).
Using Vij, determine the best solution and the worst solution to each
factor as shown in the Equation (5).
where, B is benefit related factors and C is cost related factors.
Calculate the distances of the best solution and the worst solution as
shown in the Equation (6) and (7).
