Ítem Design Verification through virtual prototyping techniques based on Systems Engineering(Springer London, 2017-10-01) Mejía-Gutiérrez, R.; Carvajal-Arango, R.; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ingeniería de Diseño (GRID)The increasing offer of software tools for product development introduces methodological questions to design engineers in terms of the easiness of tool integration and design activities' sequencing. Nowadays, Design Verification and Validation through prototyping techniques have been enriched with software solutions enabling virtual prototyping to take more product's behaviors into consideration during analysis and simulation. It is the case of the Systems Engineering module in CATIA (TM) V6 that proposes a sequential "Requirements-Functional-Logical-Physical Design" (RFLP) approach to link conceptual design activities with 3D-models and simulation. Since some practitioners traditionally use these concepts, this article presents an analysis, based on action research, to evaluate the Design Verification activities as well as the tools integration offered by the new Product Lifecycle Management vision of CATIA (TM) V6. The analysis enabled authors to refine and propose a model's nature-dependent design method, enriched from the basic RFLP concept. Additionally, the presented results also showed the benefits of using integrated approaches when designing complex products, represented in a case study on virtual Design Verification of an automotive sub-system.Ítem Engineering education through an intercontinental PLM collaborative project: The Global Factory case study(Institute of Electrical and Electronics Engineers Inc., 2015-01-01) Mejia-Gutierrez, R.; Carvajal-Arango, R.; Zins, J.This article will present the experience in the development of an intercontinental collaborative project named 'Global Factory', being the first massive academic exploration of this new way of engineering work. The main goal of the project, was to collaboratively design a virtual factory to produce vehicle combustion engines, by using the Product Lifecycle Management (PLM) software CATIA V6. It was developed collaboratively by students from different universities around the world with distributed work and a centralized database. Therefore, interdisciplinary work was encouraged, leading students to collaborate with colleagues from different disciplines and countries. Students were subject to real conditions of international work and the implied working conditions (e.g. cultural aspects, time-frames, communication limitations, use of Information and Communication Technologies (ICT), etc.). Furthermore, they had to deal with the natural complexity of the technical work as well as the global interaction aspects, being a complicated task to be developed in a novel tool. Finally, the paper will describe the analysis of the project and the educational aspects that students had to face. This project sets the basis for preparing engineers of the future, who will work in a global environment. © 2014 IEEE.Ítem A systems-engineering approach for virtual/real analysis and validation of an automated greenhouse irrigation system(Springer-Verlag France, 2016-11-01) Carvajal-Arango, R.; Zuluaga-Holguín, D.; Mejía-Gutiérrez, R.; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ingeniería de Diseño (GRID)In the context of multidisciplinary complex systems design, modelling and simulation are key components in decision making. It allow engineers to validate design alternatives at early development stages. Consequently, it is possible to reduce uncertainty on requirements compliance and secure better decisions for downstream stages of product development. This article describes the analysis of a virtual prototype of an automated greenhouse irrigation system. It is modelled and compared with the real system implementation, finding some differences and similarities between both system testing approaches. The intrinsic dependence of experimentation and modelling is also discussed as both, experimental and random data, are important to be used as inputs to validate virtual models.Ítem VIRTUAL PROTOTYPE SIMULATION CASE STUDY IN MECHATRONIC PRODUCT DEVELOPMENT BASED ON SYSTEMS ENGINEERING APPROACH(IATED-INT ASSOC TECHNOLOGY EDUCATION A& DEVELOPMENT, 2013-01-01) Mejia-Gutierrez, R.; Carvajal-Arango, R.Nowadays consumers are demanding products richer in technologies and associated services. That is why the link between disciplines, such as Engineering Design and Mechatronics, gets stronger each day, especially, due to the different functionalities and features that should be integrated in products in a more articulated manner. In order to prepare the future generation of engineers, they should be aware and must know the supporting tools recently available in the market to support and automate these interactions among disciplines. Regular engineering design approaches, start from requirements understanding and end with a physical prototype, passing by conceptual and detailed design. Nevertheless, the product design process should allow engineering students to forecast product behaviour and its validation through simulation in early design phases, before physical prototyping. In some cases, complexity increases as products require the integration of technical systems involving mechanics, electronics and control, among others. Therefore, design concepts cannot be easily tested using a traditional CAD package that needs a physical prototype for validation purposes. This article presents a case study using a Systems Engineering approach in academia (with RFLP Requirements/Functions/Logical/Physical) to develop a virtual prototype of a mechatronic product, its simulation and validation against data obtained from the real product. The RFLP method allows engineers to test designs at early design phases by using virtual prototype and virtual simulation, including behaviour and electronics. Therefore, design concepts can be validated without having the need to build physical prototypes which implies higher costs and manufacturing time. From the academic point of view, students can be aware that their design concepts will work properly in the real world by performing enriched simulation processes.
