The objective of this work is to add value to the productive system of a food company in Mar del Plata. The problematic situation is structured and its main causes are detected by applying Soft Systems Methodology in combination with dynamic simulation to model the behavior of the productive system. The problem detected is the need to increase the production capacity to improve compliance with deliveries agreed with customers. A proposal for improvement in productive activities is presented that generates added value for the client and the organization and allows solving the current situation. A simulation software is used to model and compare the current and proposed production system. The results conclude that the improvement alternative exceeds the desired production levels, achieving an increase in the level of customer service. The proposal reduces waste by adding value and improving the competitiveness of the organization. [ABSTRACT FROM AUTHOR]

Based on dynamic thermal simulations with the EnergyPlus software, an experimental module of a rural dwelling is proposed for the village of Imata, Peru, at 4519 meters above sea level, with severe climatic conditions of very low temperatures. Simulations were carried out for five module configurations, successively adding bioclimatic components, such as improvements in the insulation of the enclosure, skylight and attached greenhouse. For the month with the lowest temperatures, the average temperature in the best configuration module is 11 °C higher than the average temperature in the module corresponding to typical Imata houses. The minimum average night temperature is 18.4 °C higher than the corresponding outside temperature (- 4 °C). To maintain a temperature of 16.3 °C inside the module (adaptive model), on annual average, a daily energy of 12 kWh is required for the typical module, and 1 kWh for the best design.
