  Title Assembly Operation Tools for e-Product Design and Realization Type Book Whole
  Year 2003 Publication Abbreviated Journal  
  Volume Issue Pages -  
  Keywords Industrial Engineering  
  Abstract True competitive advantage can only result from the ability to bring highly customized quality products to the market at lower cost and in less time. Many customers are demanding customization and rapid delivery of innovative products. Industries now realize that the best way to reduce life cycle costs is to evolve a more effective product development paradigm using the Internet and web-based technologies. Yet there remains a gap between these market demands and current product development paradigms. Assembly plays a very important role in manufacturing industries, given that joints on a structure are inevitable because of the limitations on component geometric configurations and material properties along with various engineering requirements. Appropriate joints should be determined by considering mechanical and mathematical implications and assembly/joining knowledge. Currently, the effects of joining are analyzed upon completion of assembly modeling. This sequential process is arduous and time-consuming and is eliminated with the tools developed in this work. The existing CAD systems require that a product developer possess all the design and analysis tools in-house making it impractical to employ all the needed and newest tools. Existing assembly design methodologies have limitations on capturing the non-geometric aspects of a designers intent and the physical effects of joining in an Internet-based product development environment. In this work, new assembly design (AsD) frameworks and assembly operation tools (AOT) are developed to integrate AsD, virtual analysis, and decision making for e-product design and realization. The AOT include the assembly design (AsD), assembly implication (AsI), and assembly advisory (AsA) engines. The AsD formalism, which is the base of the AsD engine, represents the assembly/joining relations symbolically for computer interpretation, and the automatically generated AsD model is used for inferring mathematical/physical implications, as well as lean AsD information exchange. A new virtual assembly analysis concept is introduced to transparently predict the various effects of joining and is implemented in a service-oriented architecture. The AsA engine employs hierarchical semantic net to support an AsD decision by capturing AsD information and assembly/manufacturing knowledge. The concepts and AOT are validated using a case study of realistic mechanical assemblies.

  Title Enterprise Reengineering  A Strategic Framework and Methodology Type Book Whole
  Year 2005 Publication Abbreviated Journal  
  Volume Issue Pages -  
  Keywords  
  Abstract Manufacturing companies find themselves, whether they like it or not, in a more global and changing reality. Fiercer competition, dynamic markets, new consumer habits, stronger environmental regulations, and new technological possibilities, are forcing manufacturing companies to change. The practical effects for European manufacturers are 1) new and innovative products, 2) global value chains, 3) automation, and, 4) a shift from products to solutions. This research is addressing the changes needed for operations in a single enterprise (a group of departments, a plant, or a group of closely located plants), to take advantage of the competitive situation. For such internal operations, the new challenges require changes both in technology and practices. The main concern of this research is the practices, and how a reengineering of manufacturing and office operations can improve performance. The choice of scope is based on the assumption that operations activities are a major source for competitiveness. To reengineer operations activities in processes rather than functions, and to implement best practices wherever appropriate, can therefore provide dramatic competitive improvements.The overall objective of this research is to:“ establish enterprise reengineering as an approach that enables manufacturing enterprises to achieve fit between market requirements and operations capabilities.Enterprise reengineering is viewed as model-based and strategy driven approach that enables manufacturers to realise the soft or infrastructural aspects of an operations strategy. To support such reengineering efforts, enterprises are viewed not only from a process perspective but also from a resource, materials, information, organisations, and control perspective. Modelling and analysing enterprises from these perspectives can support their effort to implement best practices, and ensure that the practices are combined in a way that supports the overall business strategy.The overall objective is divided into more specific objectives:” To develop a strategic framework for enterprise reengineering “ To develop a consistent and practical enterprise reengineering methodology to support the formulation and realisation of operations strategies” To develop architecture for conceptual enterprise modelling that ensures a coherent, decomposed, and holistic picture of enterprise operations“ To establish flow manufacturing as a (optional) best practice programme for enterprise reengineeringTogether, the strategic framework, the methodology, and the modelling architecture should enable enterprises to achieve their performance objectives through an enterprise reengineering effort. In cases where an enterprise mapping and analysis concludes that improvements in manufacturing planning and control, order management, layout and flow, or inventory, should be performed, the flow manufacturing programme should provide practical guidance and a set of principles to support reengineering.In order to achieve these objectives, the following issues are reviewed in this thesis:1) operations strategy, 2) enterprise reengineering, 3) flow manufacturing, 4) enterprise modelling, and, 5) change management. Based on these literature studies, a strategic framework, a methodology, a modelling architecture for enterprise reengineering and a flow manufacturing programme are proposed.The major outcome of this research is an enterprise reengineering methodology, which includes strategic planning, and operations mapping, analysis, design, and implementation. The methodology consists of the following models, principles, and tools:” A operations strategy checklist“ Four flow manufacturing design principles” An architecture for conceptual enterprise modelling“ Seven change management principles” A procedural guide for enterprise reengineering“ An operations performance audit sheet” A five-step approach to flow manufacturing reengineeringThe research is based on a case study of HÅG Fast, a very successful enterprise reengineering project carried out in 1991-1992. The case study demonstrates the usefulness of the methodology to analyse and understand enterprises, and the dramatic improvements in performance that can be achieved by implementing flow manufacturing practices. In addition, the enterprise reengineering methodology has been proved useful in several field studies.

  Title Nesting Automated Design Modules In An Interconnected Framework Nesting Automated Design Modules In An Interconnected Framework Type Book Whole
  Year 2005 Publication Abbreviated Journal  
  Volume Issue Pages -  
  Keywords Product Design Generator, Automated Design Framework, Computer Aided Engineering  
  Abstract This thesis seeks to extend the PDG methodology by developing a generalized formal method for nesting PDGs in an interconnected system. A procedure for decomposing an individual PDG into reusable modules will be defined and a software architecture will be presented which takes advantage of these reusable modules. This method breaks the PDG structure into discrete elements known as PDG objects, PDG modules and PDG services. Each of these elements forms a distinct unit of reuse and each can be seen as a little PDG. Two different industrial implementations of this method are presented. These examples show that it is possible to share PDG services amongst multiple PDGs and provide a mechanism to create a PDG for a complicated system.

  Title Managing Changes to Service Oriented Enterprises Type Book Whole
  Year 2005 Publication Abbreviated Journal  
  Volume Issue Pages -  
  Keywords Computer Science  
  Abstract In this thesis, we present a framework for managing changes in service oriented enterprises (SOEs). A service oriented enterprise outsources and composes its functionality from third-party Web service providers. We focus on changes initiated or triggered by these member Web services. We present a taxonomy of changes that occur in service oriented enterprises. We use a combination of several types of Petri nets to model the triggering changes and ensuing reactive changes. The techniques presented in our thesis are implemented in WebBIS, a prototype for composing and managing e-business Web services. Finally, we conduct an extensive simulation study to prove the feasibility of the proposed techniques.

  Title Gestion du Cycle de Vie des Produits: Définitions, Problèmes Ouverts et Modèles de Référence Type Book Whole
  Year 2005 Publication Abbreviated Journal  
  Volume Issue Pages -  
  Keywords Communication and Information Sciences/Information system engineering  
  Abstract Nos travaux de thèse contribuent au domaine de la Gestion du Cycle de Vie des Produits (PLM : Product Lifecycle Management) selon deux objectifs : l'un concerne plus particulièrement l'analyse et l'état de l'art des concepts liés au domaine du PLM alors que le second va chercher à tirer avantage de ces concepts pour la formalisation d'un metamodèle adapté à la Traçabilité des produits tout au long de leur cycle de vie.La gestion intégrée de toute information relative au produit et à sa production est une des questions majeure de l'industrie. Une des réponses à cette question, actuellement d'actualité, concerne un paradigme naissant, défini par le vocable de Gestion du Cycle de Vie des Produits (PLM : Product Life Cycle Management). Dans ce contexte, l'une des problématiques concerne la traçabilité des produits tout au long de leur cycle de vie qui induit ainsi une nécessaire interopérabilité de l'information ainsi que des efforts de standardisation. Afin d'assurer ces échanges d'information, notre contribution, basés sur la situation actuelle des systèmes d'information d'entreprise (qui manipulent l'information sur les produits), doit aboutir à la définition d'une vue holonique d'un modèle conceptuel orienté produit d'un système de production, formalisant la structure du système d'information associé aux données de traçabilité des produits.
