Criterios de transferibilidad del enfoque concurrente en los procesos de diseño y desarrollo de productos de las pequeñas y medianas empresas chilenasTransferability criteria of the concurrent approach in the product design and development processes of Chilean small and middle size companies RESUMEN Este artículo presenta los resultados de la primera fase de un estudio que pretende generar un modelo de evaluación y mejoramiento de los Procesos de Diseño y Desarrollo de Productos (PDDP) de las pequeñas y medianas empresas (PyMEs) manufactureras chilenas basado en el enfoque concurrente a fin de insertarlas a los mercados competitivos actuales. En efecto, muchos autores demostraron que, en nuestra sociedad globalizada, la capacidad de una empresa en tener una buena conducción y desarrollo de las fases de diseño de productos determina una gran parte su eficacia industrial. En particular, los modelos basados en la Ingeniería Concurrente (IC) parecen ser los más apropiados para responder rápida y adecuadamente a mercados siempre más exigentes. Sin embargo, existen pocos estudios que demuestren la aplicabilidad de estos modelos a las PyMEs. Esta primera fase pretende entonces establecer criterios de transferibilidad del enfoque concurrente en pequeñas y medianas empresas, analizando el corpus teórico y experimental relativo a la Ingeniería Concurrente (IC) y su aplicación en PYME, contrastando estos análisis con los primeros resultados de una investigación explorativa y cualitativa de tres PyMEs manufactureras chilenas. Estos criterios de transferibilidad se basan por una parte sobre una interpretación del enfoque concurrente al analizar la literatura existente y los patrones de comportamiento de las PyMEs para así destacar las dimensiones críticas particulares, por otra parte, se basa en un análisis del tipo de modelo de intervención que permita su implementación en este tipo de empresas.Palabras clave: Procesos de diseño y desarrollo de productos (PDDP), ingeniería concurrente, pequeñas y medianas empresas (PyMEs), modelo de mejoramiento, tablas de madurez. ABSTRACTThe results of the first stage of a study aimed at generating a model for the evaluation and improvement of Product Design and Development Processes (PDDP) of Chilean small and middle size enterprises (SMEs) based on the concurrent approach with the aim of inserting them in current competitive markets are presented. Many authors have shown that in our globalized society the ability of a company to provide good guidance and development of the product design stages determines largely its industrial efficiency. In particular, models based on Concurrent Engineering (CE) seem to be the most appropriate to respond rapidly and adequately to ever more demanding markets. However, there are few studies showing the applicability of these models to SMEs. Therefore this first stage is aimed at establishing transferability criteria of the concurrent approach in small and middle size companies, analyzing the technical and experimental corpus related to CE and its applica...
The prototyping of a newly designed electrolytic pencil for the local cleaning of silver tarnish on artifacts comprising inseparable organic components is described. The pencil helps determine the type and amount of tarnish, define the cleaning parameters (treatment potential and duration), and provides a safe and efficient way to locally and electrolytically reduce silver tarnish. The electrolyte is conveyed to and from the surface of metal objects via a micro-porous foam and is continuously renewed by two pumps. This user-friendly and ergonomic pencil is distributed as an open source kit for self-assembly with parts fabricated using innovative and low-cost technologies. The operating modes for the pencil are described. To evaluate this new tool, the pencil was used to clean a selection of tarnished silver components from composite masterpieces in the Treasury of Saint-Maurice Abbey.
