On the Integrality of Some Facility Location Polytopes
نویسندگان
چکیده
We study a system of linear inequalities associated with some facility location problems. We show that this system defines a polytope with integer extreme points if and only if the graph does not contain a certain type of odd cycles. We also derive odd cycle inequalities and give a separation algorithm.

Total Dual Integrality in Some Facility Location Problems
Facility location, arising in a rich variety of applications, has been studied extensively in the fields of operations research and computer science. In this note we consider the classical uncapacitated facility location problem and its “prize-collecting” variant introduced by Bäıou and Barahona, and show that the linear systems associated with these problems are totally dual integral (TDI) if ...

متن کاملTight bounds on the Lovász-Schrijver rank for approximate Capacitated Facility Location∗
In the Capacitated facility location (Cfl) problem we are given a set F of facilities and a set C of clients in a common metric space. Every facility has a hard capacity ui. Opening a facility i incurs a nonnegative cost fi, while assigning a client j to facility i incurs a nonnegative connection cost cij . The goal is to open a subset F ′ ⊆ F of the facilities and assign each client to an open...
متن کاملHeuristic Methods Based on MINLP Formulation for Reliable Capacitated Facility Location Problems
This paper addresses a reliable facility location problem with considering facility capacity constraints. In reliable facility location problem some facilities may become unavailable from time to time. If a facility fails, its clients should refer to other facilities by paying the cost of retransfer to these facilities. Hence, the fail of facilities leads to disruptions in facility location dec...
متن کاملHierarchical Facility Location and Hub Network Problems: A literature review
In this paper, a complete review of published researches about hierarchical facility location and hub network problems is presented. Hierarchical network is a system where facilities with different service levels interact in a top-down way or vice versa. In Hierarchical systems, service levels are composed of different facilities. Published papers from (1970) to (2015) have been studied and a c...
