Defuzzified Number =
where, ( ) is Triangular Fuzzy Number.
To calculate the weights of the factors, the following Equation (2) was
used, and the results were shown in .
Weight of a factor j (Wj) =
where, Wij= weight of decision maker i on factor j and k is the number of
decision makers.
The result shows that the weights of the factors are in the order of
transport cost > transport time > transport service = safety > transport
distance > awareness.
