“…Solutions with p vertices are called pmedians of the graph [16]. Researchers have used the pmedian model in several problems, such as in the spatial distribution of maternity hospitals [19], in the location of public schools [20], and classic facilities-location problems [21]. The main advantages of the p-median algorithm include the following: the flexibility to manage a large variety of input formats (e.g., square-symmetric and square-asymmetric) [22], and many facility location problems can be adapted as pmedian problems through data processing [23].…”

In the current industrial revolution, additive manufacturing (AM) embodies a promising technology that can enhance the effectiveness, adaptability, and competitiveness of supply chains (SCs). Moreover, it facilitates the development of distributed SCs, thereby enhancing product availability, inventory levels, and lead time. However, the wide adoption of AM in industrial SCs creates various challenges, leading to new difficulties for SC design. In this context, this paper proposes a new design approach to AM SCs using optimization methods. More specifically, the proposed approach, comprising the pmedian and mixed-integer linear programming models, considers the decision of deploying productive resources (3D printers) in specific locations of generic spare part SCs. The approach was evaluated in a real-world use case of an elevator maintenance service provider. The obtained results demonstrated the promising capabilities of the proposed design approach in managing the challenges arising from the forthcoming widespread use of 3D printers in manufacturing SCs.

This study proposes determining optimal locations for expanding a higher education system by using populational and social criteria. With this aim, this work evaluates single objective location models in determining the optimal distribution of higher education facilities in Amazonas State, Brazil. Three optimization options are evaluated and made available to decision makers: 1) prioritize cities with a lower United Nation Human Development Index; 2) prioritize cities with a higher population, 3) favor both criteria. Also, the location must equalize student distribution between the regions of Amazonas State. With this aim, three discrete location models were evaluated: p-center model, p-median model, and p-dispersion model. The location models were designed using a Genetic Algorithm metaheuristic. A state-of-art implementation of the Genetic Algorithm that optimizes the solution and converge time was used. The expansions proposed here present lower mean values of United Nation Human Development Index compared with 0.619 from the existing distribution of campuses. The best results were obtained with the p-median model. INDEX TERMS p-median modeling, locating higher education schools, single objective location, genetic algorithm.

“…10 existing schools are maintained, 4 new schools are created and only one existing school is closed. Menezes and Pizzolato (2014) proposed location of new schools, during the years 2015 -2020, in the Guaratiba area, assessment region 5, Rio de Janeiro, Brazil, relying on capacitated p-median and maximum coverage models. They sought to minimize total student travel distance to the nearest school.…”
