Sensitivity Analysis in Minisum Facility Location Problems

Abstract

This paper considers tradeoffs between cost and perturbations of the weights in a single facility, minisum location problem over a finite set of feasible points. Specifically, the paper characterizes a tradeoff curve of variability in the weights versus the degree of optimality of a solution. The general theoretical framework includes problems of location on a tree network and location using block norms; special results are given for these cases.
