Enhancing the plant layout design process using X3DOM and a scalable web3D service architecture

This paper presents an innovative model-driven architecture enabling 3D web-based design processes in the field of large complex building (LBC) projects, such as power plant construction. This work was motivated by proposing new ways of achieving 3D CAD tasks not only for highly complex and temporary organization in the design stages but also for the whole lifecycle of such installations, which may last several decades. in this particular scenario, it is very important to share the right information with the right stakeholder at the right time, to maintain a high level of knowledge sharing. Taking into account these challenges, we propose a first implementation of interactive 3D CAD editing tools, based on the X3DOM technology and driven by a knowledge layer which utilizes a complete reference data and rules management system. To store the CAD models, a Macro-Parametric Approach has been investigated and a 3D server has been added to the traditional PDM (Product or Plant Data Management) to execute remotely complex CAD operations. This is a very promising start to deploy lightweight and smart web3D CAD editing services for the AEC (Architecture Engineering Construction) and power industries.

A Lean-based Analysis Framework Oriented Towards the Upstream Supply Chain for the Luxury Industry

For a long while the luxury industry has been restricted to a specific type of operation - that of an outstanding manufacturer for whom work is mainly manual. The industry’s attention to perfection and the image of “luxuriousness” has kept operating methods beyond any industrial logic. However, with globalisation, the luxury industry has had to develop and open up to new commercial perspectives by diversifying and producing increasingly higher volumes - with ever-shorter deadlines. To accomplish these ends, it has become crucial to develop a veritable industrial dynamic tailored to its constraints. The aim of this article is first to develop and specify the context and particularities of the luxury industry, and second to offer a framework for analysing lean product development and maturity performance of an organization in the luxury industry. The key focal points to be followed to achieve top performance in the development of luxury products are structured around processes, standards, tools and knowledge, organization, and measurement.

Combining lean and green in manufacturing: a model of waste management

Abstract In this paper, we focus our attention on the modeling of waste management as an application of environmental concern (green) integrated with lean manufacturing. The literature confirms the convergence between the two concepts, for waste reduction. Nevertheless, there are interesting avenues of research in the development of an integrated model, at the crossroads of lean and green principles. So, we propose a framework in three levels for optimizing a waste minimization program: an integrated improvement process (level 1), a strategic matrix and an integrated toolkit (level 2), and finally an “advanced 3R (Reduction / Reuse / Recovery)” method (level 3).

Long term control of 3D engineering data for nuclear power plants

The engineering of the next generation of nuclear power plants requires to take into account the whole plant lifecycle: engineering, building, operating, maintaining and decommissioning. Satisfying stronger and stronger safety regulations requires the ability to trace any engineering information during the whole life of the nuclear power plant: one hundred years. The french electricity company Électricité De France (EDF) just started a Plant Lifecycle Management (PLM) project in order to design new (or improve existing) models, methodologies and tools able to ensure that these requirements are fulfilled. Among all the information related to a power facility, 3D data aims, in this context, at providing not only the as-designed (CAD) but also the as-built representation of the geometry of the facility components (HVAC, cable trays, pipes, valves etc.) as well as their relative position. With this project, the strategic goal of EDF is to ensure to keep the control over 3D data along the whole power plant data lifecycle. The nuclear industry misses a suitable standardized and open 3D model intended to this purpose. In this paper, we introduce a macro-procedural model intended to represent nuclear power plant 3D data and we present the first architectural design decisions and experiments.

L’excellence hospitalière, ou la mise en œuvre de l'excellence opérationnelle dans le monde hospitalier

In the 80’s, the Lean Production System urged industrial companies to « think different » the operational system. Nowadays, the public hospital is facing difficulties that make revelant a global organisationnal transformation. contributions involving Lean applications in healthcare exist, but there is a lack of global and structured methodology. In this article, we propose the Healthcare Excellence framework, which transposes the Lean manufacturing principles to the specific healthcare environment. The proposed methodology for healthcare transformation is illustrated with existing projects lead in french public hospitals. MOTS-CLÉS : excellence opérationnelle, Lean, management hospitalier, excellence hospitalière.

Toward an Ontology-Based Architecture for Cloud Manufacturing

In this study we introduce a first step to build a Cloud Manufacturing architecture. Cloud Manufacturing is an emerging paradigm in which dynamically scalable and virtualized resources are provided to the users as services over the Internet. Our architecture will serve as a platform for mapping users and manufacturing resources’ providers with the aim of enhancing collaboration within Product Lifecycle Management (PLM) by reducing costs and development time. Since some vendors may use different descriptions of their services we believe that semantic web technologies like ontologies are robust tools for mapping vendors’ descriptions and users’ requests in order to find the suited service. Our ontology is under development and will include concepts from holons, PLM and Cloud Computing.

Modelling Requirements in Service to PLM for Long Lived Products in the Nuclear Field

Requirements engineering in usually considered a first step before design that is to evolve with each generation or version in a prod- uct line. Nuclear plants however, are subject to modifications during their lifetime, in their design and implementation as well as in the re- quirements they have to satisfy. Economic, technical and safety reasons lead to extending the requirements engineering process through the whole life-cycle of the nuclear plants. This article presents an ontology-based approach to integrating the requirements engineering into a PLM ap- proach for such long-lived, large-scale products.
