ontological modelling of knowledge management for human machine Integrated Design of ultra precision grinding machine
IEEE International Conference on Cloud Computing Technology and Science, 2016Co-Authors: Haibo Hong, Xing ChenAbstract:Despite the rapid development of computer science and information technology, an efficient human–machine Integrated enterprise information system for Designing complex mechatronic products is still not fully accomplished, partly because of the inharmonious communication among collaborators. Therefore, one challenge in human–machine integration is how to establish an appropriate knowledge management KM model to support integration and sharing of heterogeneous product knowledge. Aiming at the diversity of Design knowledge, this article proposes an ontology-based model to reach an unambiguous and normative representation of knowledge. First, an ontology-based human–machine Integrated Design framework is described, then corresponding ontologies and sub-ontologies are established according to different purposes and scopes. Second, a similarity calculation-based ontology integration method composed of ontology mapping and ontology merging is introduced. The ontology searching-based knowledge sharing method is then developed. Finally, a case of human–machine Integrated Design of a large ultra-precision grinding machine is used to demonstrate the effectiveness of the method.

Integrated Design approach for solving complexity of Design problem
American Journal of Operations Research, 2013Co-Authors: Kusol Pimapunsri, Serge TichkiewitchAbstract:The engineering problems today become more and more complex particularly in the area of new product development. It requires the multi-disciplinary Design method to solve complex problems. This paper presents an Integrated Design system for solving complexity during multi-disciplinary Design. Complexity could be solved if the Design problems, given by any individuals who are concerned, are structured. The Design system uses the multi-viewpoint concept to al-low experts to share their information and knowledge in common views. Knowledge modules are used to store seman-tics from the experts of different disciplines. Then the system agent acts as an internal Designer to help support the indi-viduals to translate any semantics provided from one discipline and then propagate to other related disciplines. With these tools, the Integrated Design system can structure and solve the complexity of Design problems.

qualification and certification for the competitive edge in Integrated Design
Cirp Journal of Manufacturing Science and Technology, 2010Co-Authors: Andreas Riel, Serge Tichkiewitch, Richard MessnarzAbstract:Abstract Competitive Product Design is more and more linked to mastering the challenge of the complexity and the multidisciplinary nature of modern products in an Integrated fashion from the very earliest phases of product development. Design Engineers are increasingly confronted with the need to master several different engineering disciplines in order to get a sufficient understanding of a product or a service. Industrialists demand for the certification of the required skills, as well as for their international recognition and exchangeability. This paper describes an innovative approach to establish a training curriculum and a certification in the domain of Integrated Engineering on a European level. It shows the key competences that have been identified for the new job role of Integrated Design Engineers, as well as their relevance to system competence, which is considered one of the most vital success factors of competitive product Design. It also introduces the European-wide recognized schema for professional training and certification that has been adopted for the implementation of the qualification and certification of Integrated Design Engineers, and it points out the relevance of the activity for universities.

formation and certification of Integrated Design engineering skills
DS 58-10: Proceedings of ICED 09 the 17th International Conference on Engineering Design Vol. 10 Design Education and Lifelong Learning Palo Alto CA U, 2009Co-Authors: Andreas Riel, Serge Tichkiewitch, Damian Grajewski, Zenobia Weiss, Anca Draghici, George Draghici, Richard MessnarzAbstract:Integrated Product Development is increasingly a challenge of understanding and predicting the complete product lifecycle, and of treating the product as a whole in all phases of development. This paper points out that this trend has significant implications on the competence profiles of engineers, which are nowadays insufficiently taken into account by education and training programs, as well as skill certification schemes. It proposes a skill set of Integrated Design Engineers based on the results of collaborative research and collaborations with industrialists. Key "Integrated skills" include Product Lifecycle Engineering, Innovation-driven Design, Sustainable Design, Responsible Design, Networked Collaboration, Intercultural Skills, Requirements and Knowledge Engineering. We show how the established platform and certification rules of the ECQA can be used to leverage these assets to a worldwide unique qualification and certification platform for Integrated Design with a strong international and industrial orientation.

Integrated Design of MEMS: aiming at manufacturability
International Journal on Interactive Design and Manufacturing (IJIDeM), 2007Co-Authors: Matthieu Museau, Cédric Masclet, Serge TichkiewitchAbstract:This paper is a first attempt to qualify the Design process in the field of MEMS product. Through this study, we try to analyse how the issue of manufacturability is addressed in a context of Integrated Design. This implies to understand specificities of the manufacturing process involved in the realization of these products (we focus on process derived from VLSI industry). Then we look at the main current Design methodologies to understand how the manufacturing is being taken into account. Computer aided tools associated to these methodologies are presented at the same time. Finally, we conclude on the need of specifications for a Design methodology that would provide Designers with greater independence from manufacturing constraints.

innovation and manufacturability analysis in an Integrated Design context
Computers in Industry, 2000Co-Authors: Daniel Brissaud, Serge TichkiewitchAbstract:Abstract In an Integrated Design modeller system, the constraints due to all the actors of the life cycle of a mechanical product need to be considered as early as possible while Designing. Two complementary aspects dealing with that issue are presented here. The functions–structures databases allow product innovation and solution proposals during the early Design stages. A manufacturability analysis is made through specific domain tools modelling the manufacturing process, proposing pieces of the part definition.

Structure-material Integrated Design by level sets
Structural and Multidisciplinary Optimization, 2016Co-Authors: Yiqiang Wang, Michael Yu Wang, Feifei ChenAbstract:This paper proposes a structure-material inte-grated Design method in the framework of level sets. A two-scale optimization is performed, where not only is the structural configuration optimized, but the effective properties of the constituent material are also Designed by optimizing the configuration of the periodically-arranged microstructures. In this way, the approach can simulta-neously generate optimized material distribution patterns as well as optimized materials. Due to the fact that the level set method produces material-void solutions only, the ob-tained material is uniformly distributed over the material regions of the structure in a strict sense. Three numerical examples are presented to validate the proposed method. The obtained optimal solutions illustrate that whether to Design material cells or to optimize structural configura-tions to achieve the best structural performance would be problem dependent, and thus further demonstrate the ne-cessity and validity of the Integrated Design scheme.

A PDES/STEP-based model and system for concurrent Integrated Design and assembly planning
Computer-aided Design, 2002Co-Authors: H. DuAbstract:Product data exchange and interfacing between different CAD/CAM systems are of great importance to the development of concurrent Integrated Design environments and computer Integrated manufacturing systems. This paper presents a STEP-based method and system for concurrent Integrated Design and assembly planning. An Integrated object model for mechanical systems and assemblies is first defined by a hierarchy of structure, geometry and feature. The structure is represented as a component-connector or joint multi-level graph with both hierarchical functional and assembly relations. These hierarchical relation models are then used for uniformly describing their causal relations both for assembly level and feature based single part level. The generic product assembly model is organized according to STEP, using mostly the entities of Integrated resources and partly self-defined entities, which are necessary for Design and assembly planning. Based on the generic product assembly model, STEP-based strategies and agent concepts are used for agent-based concurrent integration of Design and assembly planning. A prototype system, consisting of a CAD system, a product modeling system, an assembly planning system, and an assembly evaluation system is developed, in which product data can be exchanged between these subsystems. Details about the implementation of the system are addressed. The Integrated Design and assembly planning system can support the introduction of a new product. The results of assembly planning are feedback to the stage of assembly Design to improve on the Design. A case study is carried out for assembly-oriented Design of a gearbox, to illustrate the proposed approach and to validate the developed system.
