This paper considers the rectilinear minisum and minimax location problems
from a different point of view in that the orientation of the axes, which d
efine the distances, is now also to be optimized. This corresponds to the s
ituation where the grid of roads or aisles which connects the demand points
to the facility, can be designed at the same time as the location of the f
acility is chosen. Optimization methods are presented for both problems.
