    ABSTRACT: El éxito económico de las organizaciones depende de su habilidad para identi-ficar las necesidades del mercado y desarrollar productos que cumplan con los requerimientos a bajo costo y en el menor tiempo. Para poder llevar a cabo de la manera más eficiente este proceso de desarrollo de los productos se han desarrollado diferentes modelos del proceso de diseño, es decir, mapas o re-presentaciones de las fases de actividades que son necesarias para llevar a ca-bo la labor del diseño con sus interrelaciones. En este capítulo se realiza una revisión de los diferentes modelos del proceso de diseño y su evolución hacia modelos para el diseño concurrente. Su utilidad va desde sus aplicaciones en docencia hasta su importancia para poder realizar una planificación estructu-rada del proceso de desarrollo sin limitar los aspectos creativos, de manera que se dejen el mínimo o ningún factor al azar para dar una mayor de garantía de éxito en su ejecución. 1. INTRODUCCIÓN En la nueva economía global, las tendencias sugieren que la ventaja competitiva la tendrán aquellas compañías capaces de desarrollar productos rápidamente con alto enfoque al cliente. Las metodologías para el diseño y desarrollo de productos constituyen un marco flexible con el cual se encaminan los esfuerzos del equipo de diseño hacia la consecución de estos objeti-vos, brindándoles las herramientas de toma de decisiones y de evaluación; por tal razón, este capítulo tiene como finalidad el estudio de las metodologías de diseño y su evolución hacia los entornos de desarrollo concurrente y colaborativo muy adecuados a estos nuevos condi-cionantes del mercado. En la siguiente sección de este capítulo se hace una revisión tanto de los modelos clásicos de diseño (modelos de etapas del proceso de diseño) como de algunos actuales, modelos del proceso de desarrollo, los cuales comprenden el diseño propio del producto, así como la pla-nificación y el lanzamiento de las actividades de producción y comercialización; por lo tanto, los mismos entregan algunas de las primeras contribuciones para el diseño integrado de pro-ducto y proceso.

    ABSTRACT: The development of mechatronic products requires the integration of different technical disciplines by personnel who reside in separate locations, a fact that is particularly evident for the case of virtual enterprises. Concurrent engineering of these products can be enhanced significantly through the use of sophisticated data management and visualization tools such as Product Lifecycle Management (PLM). The key benefit of a PLM system is its ability to facilitate the coordination of the activities among geographically distributed team members. This paper describes models and procedures that were developed and implemented during the selection and configuration of a PLM environment for machine tool design and construction in a virtual enterprise. The experiences from this case, particularly the bottlenecks and how they were addressed are discussed in detail. Finally, recommendations for better deployment of PLM for similar conditions are presented.

    ABSTRACT: Globalization has created a situation of increased international competition, which has put companies under enormous pressure in order to sustain and improve their value added to customers based on mass customization and time-to-market opportunities. This has lead to more international collaboration within companies and their different facilities worldwide, or among different companies in global supply chains. In this scenario the tasks of design and manufacturing of products are being executed by different facilities of one large company or by a diversity of companies, usually at different geographical locations. To support all the product life cycle activities, modelling tools and computer applications have been created. During this research project a global collaborative engineering environment and web-based applications have been developed to demonstrate how virtual collaborative product development can be achieved and a case study is presented to demonstrate how collaborative design for high-tech products can be undertaken.

    ABSTRACT: Today, manufacturing systems must compete in increasingly diverse and demanding markets. Customers demand quick response to their needs, and products have shorter life cycles than ever before. In response to this context, the next generation of machine tools should be reconfigurable and intelligent. Reconfigurability allows for the reduction of machine design lead time, machine set-up and ramp-up time. This paper shows the development of an approach to concurrent design of reconfigurable machine tools to process bamboo, based on a concurrent design reference model to Reconfigurable Machine Tool development. In response, a methodology for the development of this type of machine tools is outlined.

    ABSTRACT: Reconfigurable machine tools (RMT) have emerged as a potential solution to meet the demand for rapid adaptation in the next generation manufacturing systems. While a significant amount of research in RMT design is available, formal design methodologies are still under development. In previous work, a modularity framework technique for the development of RMT modules was outlined. The technique focused on module functionality and constructability. While in general these characteristics are critical for the survival of any product, specific characteristics of RMT were not easily addressed by the proposed methodology. In particular, convertibility, in the form of upgradeability and adaptability, was not addressed. This article presents an enhanced modularity framework that takes into consideration the intended evolution lines of the reconfigurable machine tool. The basic principles are outlined and applied to the design of a machine tool for metal working. Recommendations for future enhancements to the framework are made, in particular, the possibility of developing a convertibility index to facilitate evaluation of candidate designs is discussed.

    ABSTRACT: Competitive advantages in the new global economy will belong to enterprises capable of develop high customized products. In order to compete, companies require adopting structured process to develop and improve their practices in Integrated Product, Process and Facility Development (IPPFD). This research project demonstrates how the methodological use of a Reference Model allows the companies to create a Particular Model to set-up successful IPPFD Processes focusing on specific issues of the company. One case study was implemented to demonstrate how the Reference Model can be used in a company to develop a New Product Development Program to redesign and improve its products.

    ABSTRACT: In response to the need for cost-effective systems than can be quickly adapted to changes in product design and manufacturing processes, the next generation of machine tools should be reconfigurable and intelligent. Reconfigurability allows for the reduction of machine design lead time, machine set-up and ramp-up time. The principal characteristics of the Reconfigurable and Intelligent Machines are modularity, convertibility, flexibility and cost-effectiveness. This paper applies a concurrent design reference model to Reconfigurable Machine Tool development. A methodology for this purpose is introduced, and the bottlenecks in the process are identified, namely, the procedure to design modules. In response, a technique for the development of modules that are consistent with the product portfolio of the machine tool builder is outlined.

    ABSTRACT: Nowadays global product development tasks are executed by different facilities usually at different geographically location, where design and manufacturing teams must work remotely. This situation requires three major issues to be tackled: (1) implementation of a collaborative Integrated Product Development process among the different companies participating in the Product Life Cycle activities; (2) establishment of environments that foster the coordination and cooperation among engineering groups; (3) integration of software tools that allows the exchange of information and knowledge among engineers in an effective and efficient manner. A reference model for integrated product, process and manufacturing systems development is described and a methodology to implement Collaborative e-Engineering Environments is proposed to provide a model to transfer the e-engineering concepts to the industry. A case study is described that applied the proposed methodologies to set-up a collaborative environment for high tech product development using low-cost technologies.

    ABSTRACT: Nowadays, the globalization of the manufacturing enterprises requires collaboration across frontiers. In order to attain effective collaboration, the information about the product life cycle must be captured and administrated in a way that supports the decision taken during the product development. In this context, the manufacturing process information needs to be shared between manufacturers. This paper introduces the SPEED (Supporting Plastic enginEEring Development) system designed to facilitate the sharing of injection-moulding information between interested parties via the Internet. Both the architecture and the functionality of the SPEED system are presented and described in this paper through a case study. The evolving issues are addressed. Finally, closing remarks and conclusions of the system are presented.
