, while the solutions for the different radii are drawn in Fig.
6.4
. In the latter,
the demand function contours as well as the knots (with blue crosses) are shown.
On the left, we focus on the optimal solution of the two extreme radii (R
D
0:45
and R
D
1:8). The optimal covered regions, i.e., the disc centered at the optimal
facilities and radius R; are plotted. On the right, the optimal covered regions for all
radii addressed are given.
