Approximation algorithms for multi-facility location
… to obtain acceptable solutions for the location of several facilities to serve customer sites. The general version of facility location problem is known to be NP-hard; For locating multiple facilities we use Voronoi diagram of initial facility locations to partition the customer sites …

Probabilistic formulations of some facility location problems
The area of facilities location covers a wide variety of problems involving both public and private sector applications. To date, the study of location problems has been restricted primarily to deterministic formulations of the problem. The present research effort investigates the effect of random …

Approximation algorithms for clustering and facility location problems
… we design and analyze algorithms for various facility location and clustering problems. The problems we study are NP-Hard and therefore, assuming P is not equal NP, there do not exist polynomial time algorithms to solve them optimally. One approach to cope with the intractability of these …

Development of a global facility location analysis tool
… corporate strategy and risks associated with a location? By looking beyond standard matrix analysis tools that provide a one number comparison of potential locations, this thesis will expand the existing tools to incorporate the views of Enterprise Architecting to provide a more complete picture …

Adaptable Spatial Agent-Based Facility Location for Healthcare Coverage
… within reasonable distances of the patients’ locations, while at the same time providing complete service coverage. However, complete service coverage is generally hampered by resource availability. Therefore, the Maximal Covering Location Problem (MCLP), seeks to locate HCFs such that as much …

A Study on Integrated Transportation and Facility Location Problem
… that simultaneously involve the planning of the location of facilities and transportation decisions from such facilities to consumers. This has been termed integrated distribution planning problems with practical application in logistics and manufacturing. In this integration, different planning …

Probabilistic formulations of some facility location problems in discrete space
… problem can be stated as follows: determine the locations of the minimum number of facilities among a discrete set of feasible location sites in order to assure that the probability each customer is covered by some facility is no less than a specified value. The second problem treated involves …

Facility location and the analysis of algorithms through factor-revealing programs
In the metric uncapacitated facility location problem (UFLP), we are given a set of clients, a set of facilities, an opening cost for each facility, and a connection cost between each client and each facility satisfying the metric inequality. The objective is to open a subset of facilities and …

A SPECIAL FACILITY LOCATION PROBLEM APPLICABLE TO THE POSTAL SERVICE NETWORK OPTIMAL DESIGN
A special facility location problem is discussed which is applicable to the design problem of a postal service network. The cost objective of this problem includes a nonlinear concave component. In addition, there is a workload balancing requirement among all facilities for which an appropriate …

Investigating the Maximal Coverage by Point-based Surrogate Model for Spatial Facility Location Problem
Spatial facility location problems (SFLPs) involve the placement of facilities in continuous demand regions. One approach to solving SFLPs is to aggregate demand into discrete points, and then solve the point-based model as a conventional facility location problem (FLP) according to a surrogate …

Optimally Locating Facilities with Variable Characteristics
Facility location problems aim at optimally locating facilities like plants, warehouses, convenience stores, shopping malls etc. They can have different objectives such as maximizing the profit gained from the customers or minimizing the costs of locating facilities and serving the customers. In …

Reliable design of interdependent service facility systems under correlated disruption risks
Facility location decisions lie at the center of planning many infrastructure systems. In many practice, public agencies (e.g., governments) and private companies (e.g., retailers) need to locate facilities to serve spatially distributed demands. For example, governments locate public facilities, …

Impact of decentralized decision making on access to cholera treatment in Haiti
… environment, individuals’ access to facility resources may suffer in comparison to a hypothetical system in which a single planner locates the facilities to optimize access for all. Furthermore, due to the unanticipated nature of humanitarian events and the urgency of the need, …
