Ítem Dual aspect model for failure forecasting in cyber-physical systems(TU-Delft, 2014-05-23) Mejía Gutiérrez, Ricardo; Opiyo, Eliab Z.; Horvath, Imre; Ruíz Arenas, Santiago; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ricardo Mejia (rmejiag@eafit.edu.co); Imre Horváth (i.horvath@TUDelft.nl); Santiago Ruiz (s.ruizarenas@tudelft.nl); Eliab Z. Opiyo (e.z.opiyo@tudelft.nl); Ingeniería de Diseño - GRIDCyber physical systems (CPSs) are complex systems whose performance depends on the interactions between heterogeneous subsystems, the external environment, and the interrelations among natural systems and its cyber-physical augmentations -- Any fault that occur during these diverse and interrelated interactions may cause failure or a malfunction of the entire system -- The traditional multi-aspects modelling techniques developed for analysing complex systems performance can to some extent fundamentally be used in the analysis of CPSs -- The problem, however, is that these modelling techniques do not consider the consequences of the integration of natural systems and cyber-physical augmentations -- In this article, we propose a novel dual-aspect modelling technique that integrates natural and CPSs functional systems -- This modeling technique includes natural systems such as plants and humans as integral parts of the system, and therefore allow us to study their interactions, influences and effects -- A cyber-physical greenhouse case study is presented to demonstrate the applicability of the proposed modelling technique -- The proposed dual aspect modelling technique will be used in the subsequent stages of our research to analyse the interactions between natural systems and CPS augmentations with a view to identify influential factors of failure in system operation as well as the cause and types or modes failuresÍtem Exploring the role of system operation modes in failure analysis in the context of first generation cyber-physical systems(Universidad EAFIT, 2018) Ruíz Arenas, Santiago; Horváth, Imre; Mejía Gutiérrez, Ricardo; Rusák, ZoltanÍtem Manufacturing process planning under a product lifecycle management approach(2010-12-08) Mejía Gutiérrez, Ricardo; Ruíz Arenas, Santiago; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ricardo Mejia (rmejiag@eafit.edu.co); Santiago Ruiz (s.ruizarenas@tudelft.nl); Ingeniería de Diseño - GRIDThe Product Lifecycle Management (PLM) concept may be used to align Knowledge Management with Manufacturing Process Planning -- This paper presents an ongoing research in the use of a PLM tool to support the process planning of machining processes, including High Speed Machining (HSM) -- The project integrates a novel and competitive PLM solution for emerging markets, such as developing countries or Small and Medium Enterprises (SME) -- A module for managing CAD/CAM information under a PLM approach is proposed and its implementation is described to clarify the Manufacturing Process Planning under a PLM environment -- The paper reports the experience using the tool and discusses opportunities and pitfalls in its use
