Bi-objective multi-assignment capacitated location-allocation problem
Optimization problems of location-assignment correspond to a wide range of real situations, such as factory network design. However most of the previous works seek in most cases at minimizing a cost function. Traffic incidents routinely impact the performance and the safety of the supply. These …

Public Bike Stations in Indianapolis: A Location Allocation Study
Location Allocation, rooted in Operations Research and Mathematical programming, allows real world problems to be solved using optimization (based on mathematics and science) and equity principles (based on ethics). Finding nearest facilities for everyone simultaneously is a task solved by …

Medical Imaging Centers in Central Indiana: Optimal Location Allocation Analyses
… a point and a line, it wasn’t until 1966 that location optimization was first applied to a problem in healthcare. Location optimization techniques are capable of increasing efficiency and equity in the placement of many types of services, including those within the healthcare industry, thus …

Algorithmic Approaches for Solving the Euclidean Distance Location and Location-Allocation Problems
… algorithmic approaches for solving the minisum location and location-allocation problems in which the Euclidean metric is used to measure distances. To overcome the nondifferentiability difficulty associated with the Euclidean norm function, specialized solution procedures are developed for both …

Balanced, capacitated, location-allocation problems on networks with a continuum of demand
Location-allocation problems can be described generically as follows: Given the location or distribution (perhaps, probabilistic) of a set of customers and their associated demands for a given product or service, determine the optimum location of a number of service facilities and the allocation of …

Network Design and Analysis Problems in Telecommunication, Location-Allocation, and Intelligent Transportation Systems
… and analysis of telecommunication networks, location-allocation distribution contexts, and intelligent transportation networks. Specifically, the corresponding problems addressed in these areas are a local access and transport area (LATA) network design problem, the discrete equal-capacity …

Static and sequential location-allocation problems on networks and areas with probabilistic demands
Location-allocation problems arise in many practical settings and may be generically stated as follows: Given the location or distribution of a set of customers and their associated demands, simultaneously determine an optimal location of a number of supply facilities and their allocation of …

A location-allocation model and algorithm for optimally locating shelters to minimize evacuation times
Location â allocation models are designed to seek the concurrent location of a set of service facilities and an allocation scheme to satisfy the demands of a set of customers or users of a given system. If the location-allocation model is based on a graph-theoretic formulation, then the …

A reformulation-linearization based implicit enumeration algorithm for the rectilinear distance location-allocation problem
… with the analysis of a Rectilinear Distance Location Allocation Problem, where the costs are directly proportional to rectilinear distances and the amount shipped. The problem is formulated as a Mixed Integer Bilinear Programming Problem and as a Discrete Location Allocation Problem. Using …

Investigating the Role of Location-Allocation Models in Planning the Locations of Dry Fire Hydrants
… This thesis investigates the role of GIS location-allocation model (LAMs) as a tool to aid fire managers in planning the locations of numerous dry hydrants. LAMs are designed to place central service facilities in a configuration that optimally serves geographically dispersed demand. One …

Generation and optimisation of real-world static and dynamic location-allocation problems with application to the telecommunications industry.
The location-allocation (LA) problem concerns the location of facilities and the allocation of demand, to minimise or maximise a particular function such as cost, profit or a measure of distance. Many formulations of LA problems have been presented in the literature to capture and study the unique …

Preparing for out of hospital cardiac arrests (OHCA) in Riyadh, Saudi Arabia: A GIS scenario-modeling approach
<p>This study employed location-allocation modeling and a geographic information system (GIS) to study the current placement of automated external defibrillators (AEDs) in relationship to neighborhoods in Riyadh City, Saudi Arabia, and to determine the optimal locations for additional AEDs in the …

BUBLS : a mixed integer program for transit centre location in the Lower Mainland
… model is developed to determine both the optimal location of transit centres to serve BC Transit's Lower Mainland route network and the optimal allocation of buses to those centres. The existing five transit centres are explored as well as five candidate facilities. The model considers nonrevenue …
