An Efficient Solution Approach for the p -Median Problems with Spatially Autocorrelated Weights
The p-median problem (PMP) is a classical location-allocation problem that involves simultaneously determining the locations of facilities and allocating demand points (nonfacilities) in a discrete space. The PMP is known to be NP-hard. Given its wide applicability, obtaining optimal solutions for large instances, particularly when multiple optimal solutions exist, remains computationally challenging. Nevertheless, there is a continuing and consi…
A Spatial Planning Model for Obnoxious Facilities with Spatially Informed Constraints
This research aims to develop a novel spatial optimization model for locating obnoxious facilities. While various obnoxious facility location problems (OFLP) have been introduced, the optimal spatial arrangements in existing models may not adequately reflect the real-world conditions, such as the distribution of population and locational restrictions across areas in a region, often offering extreme peripheral or clustered recommendations that ign…

This research employs a spatial optimization approach customized for addressing equitable emergency medical facility location problems through the p-dispersed-median problem (p-DIME). The p-DIME integrates two conflicting classes of spatial optimization problems, dispersion and median problems, aiming to identify the optimal locations for emergency medical facilities to achieve an equitable spatial distribution of emergency medical services (EMS)…
The Majority Theorem for the Single ( p = 1) Median Problem and Local Spatial Autocorrelation
Except for about a half dozen papers, virtually all (co)authored by Griffith, the existing literature lacks much content about the interface between spatial optimization, a popular form of geographic analysis, and spatial autocorrelation, a fundamental property of georeferenced data. The popular p ‐median location‐allocation problem highlights this situation: the empirical geographic distribution of demand virtually always exhibits positive spati…
Assessing trauma center accessibility in the Southeastern region of the U.S. to improve healthcare efficacy using an anti-covering approach
Accessibility to trauma centers is vital for the patients of severe motor vehicle crashes. Many vehicle crash fatalities failed to reach the proper emergency medical services since the accident location was far away from trauma centers. The spatial discordance between the service coverage area of trauma centers and actual locations of motor vehicle accidents delays the definitive medical care and results in death or disability. Many fatalities wo…
