The vehicle routing problem is one of the most studied problems in Operations Re-search. Different variants have been treated in the past 50 years and with technological advances, new challenges appear. In this thesis, we introduce a new variation of the VRP appearing in wireless networks. The new characteristic added to this well-know problem is the possibility of pick-up information via wireless transmissions. In the con-text considered here, a unique base station is connected with the outside and a vehicle is responsible for collecting information via wireless connection to the vehicle when it is located in another sufficiently close station. Simultaneous transmissions are permitted. Time of transmission depends on the distance between stations, the amount of infor-mation transmitted, and other physical factors (e.g obstacles along the way, installed equipment). Information to be sent...

The article proposes one model for the delivery problem. We decided to make a model of mathematic programming that can answer questions on how to realize the delivery of articles from one point named warehouse, to destiny places; looking to minimizing costs when translating or transporting goods or articles. The results obtained for the model, to fulfill an average demand of 80 boxes to deliver, require of 5 small lorries for an optimal delivery; it means only 5 routes or tours are needed to fulfill all delivery to customers.

This article aims to propose a quantitative criterion to evaluate the feasibility of implementing solutions based on linear programming for solving the vehicle routing problem (VRP). An experimental design was used to measure the relative solution time with a proposed linear programming model. The sample was randomized employing three dispersion scenarios of the delivery points: poorly scattered, scattered and very scattered. A linear programming solver was used to determine the time and iterations necessary for solving the model. As a result, the solution time was found in terms of the number of delivery points and the number of iterations for the proposed scenarios, and the time required to solve the problem was predicted using the proposed model. The research concludes with a proposal of the number of viable points to be solved by linear programming.

This article focuses on reflecting on how transdisciplinarity in education fosters an integrative and creative vision, where learning is not limited to the traditional boundaries of disciplines. Transdisciplinarity, by allowing dialogue between various areas of knowledge, helps students establish meaningful connections between concepts and their practical application in the real world, promoting an education focused on active and social learning. This approach also makes students protagonists of their educational process, since learning becomes a journey of self-discovery and participation, where they can see the direct impact of their knowledge on the solution of complex problems and on their personal development. Furthermore, it analyzes how curricular innovation based on transdisciplinarity facilitates adaptation to the changes and challenges of the 21st century, providing students wi...

This work aims to share research experiences in the perspective of communication and social development, particularly in what we have called the rurban problem. This is an idea that invites us to understand the survival experiences of thousands of family groups that, throughout the continent, work with elements, knowledge and rural practices in urban settings. Their presence stresses the dominant conceptions about what the idea of city is or should be. To address these experiences we develop a methodological strategy based on confl icting milestones as events that reveal to the public sphere tensions of senses between the modern urban and alternative conceptions. Specifically, the milestones can be identified from public policies that aff ect the social groups of interest.
