La Curva en S como Herramienta para la Medición de los Ciclos de Vida de Productos

The aim of this article was to carry out a study of the life cycles of three products of Colombian companies; based on a logistic model of population growth as a life cycles measurement tool. We found that the products life cycles have a similar behavior to the population growth, according to an S curve. The inflection points of the curves were obtained by a nonlinear regression. These points might be used as a tool for strategic decision making in products, in terms of identifying key instants for launching technological innovations, investments and execute marketing strategies.

Ciclo de Vida de Tecnologías y Curvas en S Aplicadas en Subproductos de la Agroindustria Piscícola

espanolSe analiza el ciclo de vida de tecnologias disponibles a traves del metodo de las curvas en S en tres tecnologias: proteina hidrolizada, alimentacion animal y probioticos, relacionadas con subproductos de la industria piscicola. Se construyeron estrategias de busqueda para articulos y patentes en bases de datos especializadas tales como Scopus y Free Patents On-line. Para el analisis de la informacion se utilizo las curvas en S a traves del calculo del punto de inflexion. Esto permite determinar el estado de la tecnologia dentro de su ciclo de vida y ayudar a la toma de decisiones frente al momento adecuado para ejercer mecanismos de propiedad intelectual y derecho tecnologico y sugerir estrategias de monitoreo e inversion. Entre los resultados mas importantes se observa que considerando articulos publicados, se encuentra que dos de las tecnologias analizadas, proteina hidrolizada y probioticos no han alcanzado su punto de inflexion. Lo mismo ocurre en patentes para alimentacion animal. Sin embargo, la tecnologia de proteina hidrolizada, desde el punto de vista de articulos, entrara a su fase de madurez y declive despues del ano 2016. EnglishThe life cycle of available technologies through the S-curves method on three technologies is analyzed: hydrolyzed protein, animal feeding and probiotics, related to products of the fish industry. For this, strategies were constructed to search articles and patents in specialized databases such as Scopus and Free patents online. For the analysis of the information, S curves were used for calculating the inflection point. This determines the state of technology within its life cycle and helps decision making regarding the right time to exercise mechanisms of intellectual property and technology law, and suggest strategies of monitoring and investment. Among the most important results it is observed that in articles, two of the technologies discussed, hydrolyzed protein and probiotics have not reached their turning point, and the same happened with patent for animal feeding. However, the technology of hydrolyzed protein, from the point of view of the articles, will enter its phase of maturity and decline after 2016.The life cycle of available technologies through the S-curves method on three technologies is analyzed: hydrolyzed protein, animal feeding and probiotics, related to products of the fish industry.

Prospectiva 2025 de la Carrera de Ingeniería Química en algunos Países pertenecientes a la Organización de Estados Americanos (OEA)

espanolEn el marco de la iniciativa Ingenieria para las Americas (EFTA, Engineering for the Americas), programa que establece las necesidades de mejoramiento y modernizacion de la ensenanza de la ingenieria en los paises miembros de la Organizacion de Estados Americanos (OEA), se llevo a cabo el estudio prospectivo de la Ingenieria Quimica al 2025. El estudio tiene como objetivo el identificar y priorizar nuevas tendencias, temas, tecnologias, criterios de calidad para la Ingenieria Quimica para el ano 2025. El estudio prospectivo fue realizado consultando a expertos nacionales e internacionales a traves de tres rondas Delphi, por medio de un documento digital enviado por correo electronico. El estudio se centro en el analisis de siete areas medulares de la ingenieria quimica: tecnologias, lineas de formacion, ingenieria de sistemas de procesos, fenomenos de transporte y operaciones unitarias, fisicoquimica y termodinamica, quimica e ingenieria de las reacciones y criterios de calidad para la educacion en ingenieria quimica. El estudio arrojo en total 85 temas prioritarios. EnglishIn the framework of the Engineering for the Americas program (EFTA), that establishes the need for the quality improvement and modernization of engineering education in member countries of the Organization of American States (OAS), a prospective study of chemical engineering by 2025 was performed. The objective of the study is identifying and prioritizing new tendencies, topics, technologies and quality criteria for the chemical engineering profession. The prospective study was done consulting national and international experts through three Delphi rounds by submitting a document via email. The study focused on analysing seven core areas of chemical engineering: technologies, formation lines, systems process engineering, transportation phenomena and unit operations, physical chemistry and thermodynamics, chemistry and reaction engineering, quality criteria for education in chemical engineering. The study covered 85 priority issues.
