N problem, then the model to become solved. The choice of theAxioms 2021, 10,5 offield has been made on two key criteria: the initial is definitely the suitability of your chosen city to have transport systems in a position to utilize a network of ULS, the second that of data availability. Then, the city of Barranquilla has been selected considering that it can be a mediumsized city inside the north area of Colombia, getting the fourth city in the nation when it comes to economic value, presents a city distribution structure that incorporates numerous sorts of ULS, in addition to a multiplestage data collection procedure was carried out to retrieve information and facts to interactively construct the model. The primary goal of this research becoming to propose an optimization model and resolve it, representing a reality and being replicable to other contexts, an iterative information collection approach has been deployed for describing the issue and validating both the model along with the option. To perform that, a set of 9 stakeholders (8 providers and 1 public stakeholder) have been interviewed, and quite a few field observations have been carried out. Every stakeholder has been interviewed three occasions, at unique moments, first to define the ULS in Barranquilla and select the ULS kinds, second to define and model the transport systems, and third to validate the hypotheses and assumptions in the model. That information collection permitted to define the choice difficulty (presented in Section three.1) then the MIP model was developed and solved with linear 5′-O-DMT-rU custom synthesis programming (presented in Sections 3.two and 4). 3.1. Trouble Description As outlined by published literature, in Colombia, Logistics Centers are understood as gear strategically located in very productive regions to concentrate and deliver complementary services towards the territory’s most important activities and operate according to the physical integration of your territory, for the strengthening of its production activities and for the consolidation of politicaladministrative ties that promote territorial competitiveness [71]. In Colombia, the improvement from the logistics sector has been one particular in the country’s greatest bets in recent years, within a logical attempt to take advantage of the availability of land of 23 Axioms 2021, ten, x FOR PEER Review 6 and the excellent strategic place with the country’s maritime ports, particularly within the northern Caribbean coast (see circle in Figure two).Figure 2. Place from the city of Barranquilla, Colombia. Figure two. Location from the city of Barranquilla, Colombia.This paper considers the case of the city of Barranquilla, which can be administratively Inside the example of Barranquilla, the city has various places of economic activity, acdefined as aby the creation of many industrial places for the reception of of Colombia. In companied particular, industrial, and port city positioned in the northern coast Gamma-glutamylcysteine MedChemExpress manufacturing recent years, Barranquilla and its metropolitan region varieties of a robust are mainly getting a organizations, logistics and specialized solutions. These have hadactivities vocation of located logistics, industrial, and district, extending from north to south as well as the 30th Street, Corin the eastern zone with the specialized solutions center, whose basic job would be to act asdialidad, and Circunvalar Avenue corridors as defined in the Land Management Plan in the city of Barranquilla [72] (see Figure 3). All these spaces act as logistic nodes that deliver solutions towards the requirements of your region. Nevertheless, due to the great development from the city through the past decade, the logistics need.
