we first evaluate the impact of coverage radius on the selected places, and then
through some sensitivity analysis done on the weight of objective functions, the
output of model is assessed. Note that (i) the value of a di in all examples is calculated
based on the distance between provinces of Iran, and (ii) we use p¼1 in Eq. 5.11 for
all examples.
As presented in Table 5.8, by increasing the coverage radius, both cost allocated
to establish distribution centers (i.e., Z 2 ) and the utility of selected places are satisfied
simultaneously. It means that when there is not limitation in the coverage radius of
candidate places, the result provided by MCDM is to a great extent acceptable.
To evaluate the role of objective functions in the places selected for bioethanol
distribution centers, we solve the model for coverage radius 500. As Table 5.9
