Analysis of energy consumption in Colombia using the holt method

Energy production is constantly facing major challenges today, because despite initiatives to promote the insertion of renewable energy, electricity consumption has shown considerable growth in recent years. In order to use an instrument that facilitates forecasts and predictive processes for the design of strategic plans associated with energy management, the application of the Holt Method is proposed using data on electricity demand in Colombia, GDP per capita and industrial value added, making an analysis of the last 10 years, based on figures from the World Bank. The final results predict that energy consumption for the period 2018-2020 will be between 66,231 GWk and 66,885 GWk

Algorithm Integration Behavior for Discovering Group Membership Rules

Information exploitation processes use different data mining algorithms for obtaining knowledge patterns from data obtained on the problem domain. One of the assumptions when working with these algorithms is that the complexity of the membership domain of the cases they use does not affect the quality of the obtained results. So, it is important to analyze the behavior of the information exploitation process through the discovery of group membership rules by using clustering and induction algorithms. This research characterizes the complexity of the domains in terms of the pieces of knowledge that describe them and information exploitation processes they seek to discover. The results of the experiments show that, in the case of the process for discovering group membership rules, the quality of the patterns differs depending on the algorithms used in the process and the complexity of the domains to which they are applied

Assessing the Impact of lean tools on production and safety by a multicriteria decision-making model and statistical analysis: a case study in textile sector

The global competitiveness creates an enormous pressure on companies as they need to reduce production costs in order to increase productivity. In this sense, the SMED and 5S tools appear as competent tools to reduce the waste associated with these processes. This work aims to study and assess some processes in a company in the textile sector. Improvement proposals supported in the SMED and 5S methodology are presented in different areas of the company. Advantages, investments, and respective return times are presented. Regarding to SMED, reductions in setup time in the order of 30–40% were obtained with investment return times between 6 and 7 months. The implementation of the 5S allowed to reduce the time and distance traveled for a given task. The reorganization of the area, it was possible to obtain a space gain of about 58 m2. For this purpose, a multi-criteria decision model was designed to diagnose the critical areas for the implementation of Lean tools. Then, a questionnaire was also applied to the workers, with the goal to assess the impact of the implementation of lean philosophy in the field of occupational safety
