Complex Industrial Sociotechnical Systems Dynamics Modeling and Ramp-up

The aim of this research is to study emerging ramp up scenarios in the context of complex sociotechnical dynamic systems. These represent industrial and manufacturing companies that are facing fierce competition due to globalization and free trade, and the race to be in the market first with new products. Furthermore, for every manufacturer to launch their newly designed products in market and introduce the latest functionality attributes, or improve quality of their products, effective and fast ramp up is necessary for capturing a good market share. This makes the production ramp up a back bone in modern manufacturing; as its effective management enables faster ramp-up every time a change is brought in the quality, quantity features and fabrication at design, system and process level while integrating systems logical and physical enablers. In this context, models of ramp up scenario have been explored by setting up nonlinear system dynamic models in order to understand complex trends and behaviours for large and complex systems. Apart from that, novelty of these introduced system dynamic models is the set-up of an analogy to understand what impact they can produce when the respective parameters are perturbed and how this will affect the whole system and related sub-systems when they together form a system of systems (SOS). Prior research has demonstrated that variety, due to mass customization and personalization, introduces complexity in the design as well as in manufacturing process due to production mix. Complexity is modelled and implemented, not only at the system and sub system levels but also at machine level and product level, by improving design for assembly (DFA) and design for manufacturing (DFM). In the end, sociotechnical aspects and risk assessment involving triple bottom line impact factor analysis have been explored with respect to new product design by studying utility function and trigonometry. Finally, a comprehensive model is developed and analyzed with human behavior core attributes by applying Porter\u27s theory of motivation and system dynamic. This model highlights major impacts of motivation theory, by providing intrinsic and extrinsic rewards impact on labor which enables an understanding of behavior pattern of labour in relation to work assigned. Lastly, but not the least, this dissertation has contributed and demonstrated the potential usefulness of modeling complex industrial sociotechnical systems by using system dynamic approach for ramp-up

Papers presented at the Second Annual Workshop on Space Operation Automation and Robotics (SOAR '88), hosted by Wright State University at Dayton, Ohio, on July 20, 21, 22, and 23, 1988, are documented herein. During the 4 days, approximately 100 technical papers were presented by experts from NASA, the USAF, universities, and technical companies. Panel discussions on Human Factors, Artificial Intelligence, Robotics, and Space Systems were held but are not documented herein. Technical topics addressed included knowledge-based systems, human factors, and robotics

Orchestration de web services fiables

L’Informatique Orienté Services représente un paradigme pour construire des applications distribuées sur Internet. L’Architecture Orientée Services(SOA) est un style architectural qui permet le développement de ces applications à base de services. Au cours de la dernière décennie, l’orchestration des services Web est devenue un domaine très actif dans la recherche scientifique et académique. Bien que de nombreux défis liés à l’orchestration aient été abordés, la fiabilité de l’orchestration et de sa vérification restent encore un sujet ouvert, prérequis et important de fait que ces orchestrations affectent aujourd’hui plusieurs activités quotidiennes. Cette thèse focalise sur le sujet d’orchestration des Services Web Fiables. En particulier, elle contribue avec un ensemble d’approches, de techniques et d’outils pour améliorer la sélection et l’orchestration des services web fiables. Premièrement, elle affine les phases du cycle de vie d’orchestration de services web afin d’assurer une vérification continuée de fiabilité lors des phases de conception et d’exécution. En outre, elle propose une architecture conceptuelle basée sur un registre de service amélioré, pour la mise en œuvre d’orchestrations fiables. Deuxièmement, elle présente une approche de mesure de similarité entre les services web. L’approche repose sur la comparaison des interfaces WSDL de services. L’approche sert à identifier les relations de similarité, de substituabilité et de composabilité entre services. L’outil WSSIM a été développé pour mettre en œuvre l’approche proposée. Pour validation, l’outil a été expérimenté avec un ensemble important de services web réels. Troisièmement, la thèse contribue avec une approche pour l’identification des substituts de services simples et complexes. L’approche utilise les techniques de mesure de similarité, la classification de service avec FCA et l’analyse de fiabilité pour identifier et sélectionner les meilleures substitutes. Un ensemble d’algorithmes aient été proposés pour décrire le processus d’identification. Quatrièmement, pour examiner la réputation des services comme un autre critère de fiabilité, la thèse introduit un Framework et un modèle mathématique pour la gestion de réputation de service We
