Application of an experimental design of D-optimum mixing based on restrictions for the optimization of the pre-painted steel line of a steel producer and marketing company

The inherent need to optimize production processes allows the generation of new knowledge that allows companies to achieve new horizons in terms of efficient management of productive resources, this study allowed to achieve a new advance in the efficiency of the pre-painting process, where the search focused on the maximization of the hardness of the paint on the metallic surface and the minimization of the percentage of solids in the paint, and by means of the application of a D-Optimo experimental design based on restrictions, it was determined that the Process variables: Monomer, Interlacer and Resin have a statistically significant relationship both with the hardness of the paint layer and with the percentage of solids in the paint. The optimum hardness values achieved are above the restriction imposed by the company to maintain the Knoop hardness value above 25, in the same way it was possible to achieve that the percentage of the solids found is below 30%, This being the minimum value desired by the leaders of the process

Influence of lighting and noise on visual color assessment in textiles

Color is a human perception of the light reflected by an object. It is an appreciation that depends on the way the human´s eyes detect the reflected light and the way the brain processes it. However, for industry, it is an attribute of product appearance and its observation allows the detection of certain anomalies and defects [1]. Therefore, color is a characteristic that allows to judge an object by creating conditions for its acceptance or rejection [2]. In this research, a laboratory experiment was carried out to analyze different factors involved in visual color evaluations in textiles. A complete factorial experiment design was carried out in which the analyzed factors were lighting, noise, color and participants

Procesos industriales I

El Ingeniero Industrial observa a la manufactura como un mecanismo para la transformación de materiales en artículos útiles para la sociedad. También es considerada como la estructuración y organización de acciones que permiten a un sistema lograr una tarea determinada. En el caso de la ingeniería industrial el concepto de proceso adquiere gran importancia, debido a que el desarrollo profesional de esta carrera, obliga a la reflexión sobre la manera en la que se debe: Planear, integrar, organizar, dirigir y controlar Actividades fundamentales que permiten al Ingeniero Industrial lograr sus objetivos en el ejercicio de su profesión

Investigación de operaciones I

Existe una gran diversidad de situaciones de decisiones en el campo de aplicación de la ingeniería industrial, pero hay un conjunto de problemas que por sus características pueden ser expresados en forma matemática mediante modelos de programación lineal para ser resueltos de forma óptima. Esto constituye una gran ayuda cuando los recursos son escasos y se deben por tanto emplear de la mejor manera posible. Esta herramienta analítica empleada creativamente por los Ingenieros Industriales contribuye sin duda al mejoramiento de las operaciones al interior de una organización, lo cual se traduce en reducción de costos, incrementos en la productividad entre otros beneficios

Best Environmental Management Practice in the Fabricated Metal Product manufacturing sector

This report encloses technical information pertinent to the development of Best Environmental Management Practices (BEMPs) for the Sectoral Reference Document on the Fabricated Metal Products manufacturing sector, to be produced by the European Commission according to Article 46 of Regulation (EC) No 1221/2009 (EMAS Regulation). The BEMPs, both of technological and management nature (identified in close cooperation with a technical working group) address all the relevant environmental aspects of the Fabricated Metal Products manufacturing facilities. The BEMPs described in this report provide guidance on the cross-cutting issues and optimisation of utilities of the manufacturing facilities. Moreover, the BEMPs cover also the most relevant manufacturing processes, looking at energy and material efficiency, protecting and enhancing biodiversity, using of renewable energy and using rationally and effectively chemicals e.g. for cooling of various machining processes. Each BEMP gives a wide range of information and outlines the achieved environmental benefits, appropriate environmental performance indicators to measure environmental performance against the proposed benchmarks of excellence, economics etc. aiming at giving inspiration and guidance to any company of the sector who wishes to improve its environmental performance.JRC.B.5-Circular Economy and Industrial Leadershi
