A discrete equal-capacity p-Median problem
… with the analysis of a discrete equal-capacity p-median problem, where the costs are directly proportional to the shipping distance and the amount shipped. A mixed integer programming formulation of the unbalanced, but equal capacitated case is analyzed. First we develop a dynamic programming …

Augmenting Indiana's Groundwater Level Monitoring Network: Optimal Siting of Additional Wells to Address Spatial and Categorical Sampling Gaps
… discrete facility location model known as the p-median problem, and solved to optimality using a mathematical programming package.

An algorithmic approach to continuous location
We survey the p-median problem and the p-centre problem. Then we investigate two new techniques for continuous optimal partitioning of a tree T with n - 1 edges, where a nonnegative rational valued weight is associated with each edge. The continuous Max-Min tree partition problem (the continuous …

Capacitated, unbalanced p-median problems on a chain graph with a continuum of link demands
This study is concerned with the problem of locating p capacitated facilities on a chain graph, and simultaneously determining the allocation of their supplies in order to satisfy a continuum of demand which is characterized by some weighted probability density function defined on the chain graph. …

Network Design and Analysis Problems in Telecommunication, Location-Allocation, and Intelligent Transportation Systems
… of algorithmic approaches for solving problems that arise in the design 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 …

Integrating Simulation–Optimisation for Multi-Objective Blood Supply Chain Network Design
… framework for the BSC location–allocation problem. The model incorporates demand uncertainty and environmental considerations, specifically CO₂ emissions, to determine the optimal number, location, and allocation of both permanent and mobile blood collection facilities while minimising …

Optimizing Equity in Healthcare Access: An Integer Programming Approach to Emergency Department Closures and Travel Burden Disparities in Ontario
… within this framework. The Capacitated p-Median Problem (CpMP) model identifies closures that minimize patient travel times, with results aligning to some historical closures (e.g., Durham Memorial and Chesley District), reflecting sensitivity to factors such as ED proximity and urban …

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 …

A metaheuristic and simheuristic approach for the p-HUB median problem from a telecommunication perspective
… d'aquests reptes es poden modelitzar com a problemes d'optimització. El primer objectiu d'aquest treball és proporcionar un revisió de la literatura sobre com s'han utilitzat aquestes tècniques tradicionalment per a tractar els problemes d'optimització associats a sistemes de …

Modeling and Analysis of a Feedstock Logistics Problem
… dissertation, we address a feedstock logistics problem associated with the delivery of switchgrass for conversion into biofuel. In order to satisfy the continual demand of biomass at a bioenergy plant, production fields within a 48-km radius of its location are assumed to be attracted into …
