On a connection between facility location and perfect graphs

چکیده
We characterize the graphs for which a linear relaxation of a facility location problem defines a polytope with all integral extreme points. We use a transformation to a stable set problem in perfect graphs. Based on this transformation, these graphs can be recognized in polynomial time. © 2014 Elsevier B.V. All rights reserved.

Inverse and Reverse 2-facility Location Problems with Equality Measures on a Network
In this paper we consider the inverse and reverse network facility location problems with considering the equity on servers. The inverse facility location with equality measure deals with modifying the weights of vertices with minimum cost, such that the difference between the maximum and minimum weights of clients allocated to the given facilities is minimized. On the other hand, the reverse c...
متن کاملAn integrated model for designing a distribution network of products under facility and transportation link disruptions
Due to occurrence of unexpected disruptions,a resilient supply chain design is important. In this paper, a bi-objective model is proposed for designing a resilient supply chain including suppliers, distribution centers (DCs), and retailers under disruption risks.The first objective function minimizes total costs. The second objective function maximizes satisfied demands. We use the augmented e-...
متن کاملA fuzzy capacitated facility location-network design model: A hybrid firefly and invasive weed optimization (FIWO) solution
Facility location-network design (FLND) problem, which determines the location of facilities and also communication links between the demand and facility nodes, is arisen from the combination of the facility location and network design problems. This paper deals with fuzzy capacitated facility location-network design model which aims to select the facilities and candidate links in a way that yi...
متن کاملOn the facility location problem: One-round weighted Voronoi game
Voronoi game presents a simple geometric model for Competitive facility location problems with two players. Voronoi game is played by two players known as White and Black, they play in a continuous arena. In the one-round game, White starts game and places all his points in the arena then Black places her points. Then the arena is divided by distance between two players and the player with the ...
متن کاملNew spatial clustering-based models for optimal urban facility location considering geographical obstacles
The problems of facility location and the allocation of demand points to facilities are crucial research issues in spatial data analysis and urban planning. It is very important for an organization or governments to best locate its resources and facilities and efficiently manage resources to ensure that all demand points are covered and all the needs are met. Most of the recent studies, which f...
