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.

Expone un algoritmo de punto proximal inexacto que utiliza cuasidistancia para resolver problemas de minimización en espacios Euclidianos. Este algoritmo ha sido motivado por el método proximal introducido por Attouch, Bolte y Svaiter, sección 4 (Math Program, Ser A 137:91-129), pero aquí considera cuasidistancia, para funciones objetivo arbitrarias (no necesariamente diferenciables), errores vectoriales en el residual del punto critico regularizado. Se obtiene bajo algunos supuestos adicionales la convergencia de esta sucesión producida por el algoritmo a un punto crítico del problema.

Since the nineties, the inclusion of technological components in the training of translators has been a need identified by translation professionals and academics. In this context, a cross-sectional exploratory study was proposed, aimed at looking into the inclusion of translation-applied computer sciences in the translation programs offered at public universities in Argentina, both in specific technology courses and in other curricular and extracurricular areas. Based on the information contained in documentary sources collected by the research project “Training in Translation and Interpretation in Argentina” (04/J025, UNComahue), and on the answers to questionnaires administered to the directors of the 18 study programs included, this article presents some preliminary conclusions: a minority of the study programs being researched contain a mandatory course on translation-applied co...

Amid debates on Pierre Bourdieu’s field theory and the criticism that its consolidation restricts sociology to the study of such spaces, this article aims to: (a) demonstrate that this theoretical framework and its investigative program do not prevent Bourdieu from exploring alternative research approaches; and (b) show that agents’ experiences constitute a relevant object for him. Through an interpretative reading that articulates the conceptual foundations of habitus with the books The Weight of the World and The Inheritors, the empirical potential of the notion of experience is emphasized. From this perspective, the discussion fosters an approach focused on examining this dimension of practice, proposing it as a Bourdieusian sociology of experience. The article’s main contribution lies in exploring the analytical possibilities of this notion, an aspect that remains largely under...

The aim of this study was to develop a high acceptability mixed nectar and low cost. To obtain the nectar mixed considered different amounts of passion fruit, sweet pepino, sucrose, and completing 100% with water, following a two-stage design: screening (using a design of type 23 + 4 center points) and optimization (using a design of type 22 + 2*2 + 4 center points); stages that allow explore a high acceptability formulation. Then we used the technique of Linear Programming to minimize the cost of high acceptability nectar. Result of this process was obtained a mixed nectar optimal acceptability (score of 7), when the formulation is between 9 and 14% of passion fruit, 4 and 5% of sucrose, 73.5% of sweet pepino juice and filling with water to the 100%. Linear Programming possible reduced the cost of nectar mixed with optimal acceptability at S/.174 for a production of 1000 L/day.

This paper aims to explain and present a proposal to introduce Disaster Risk Management (DRM) topics into ESAN Graduate School of Business Master’s programs. Although disasters have cost Peru more than USD 7,600 million in the past 2 decades the business sector, particularly Small and Medium Enterprises, have not developed preventive or continuity plans mainly because they are not familiar with DRM topics. Taking this into consideration, the paper presents a detailed academic/curricular proposal for DRM topics such as business continuity, business ethics, corporate social responsibility, and sustainable management. Additionally, it introduces the idea of promoting Disaster Risk Management (DRM) topics to the Peruvian business community as a strategy to enhance the graduate education.
