Architecture as a means of labour : architecture contributing to contextual events through its consumption a clothing production facility in the City of Pretoria

Wadee, Salma 09 December 2010 (has links)
Traditional paces of production in an urban context have been crudely built as machines, exploiting the resources of a location without care for the consequences. Their success has been measured primarily in terms of how efficiently they can accommodate a particular process in order to achieve an end product. This dissertation explores the manifestation of a new model for a light production facility within an urban context. A new clothing production facility is proposed in reaction to the infestation of imported apparel wear within the city. The new facility punctures into existing structures of a production typology, exploring how edge conditions and production processes can become more responsive to the urban environment, advocating a hybrid production facility. The design of the facility is informed by a theoretical premise, exploring labour, which refers to elevating the act process above product. This draws parallels to the way in which architecture can, through cyclic processes, become both artefact and utility within its context. / Dissertation (MArch(Prof))--University of Pretoria, 2010. / Architecture / unrestricted

Conception de systèmes d'analyse et de contrôle en ligne pour une unité de production de solution d'enrobage en continu pour comprimés pharmaceutiques

Belley, Sophie January 2014 (has links)
Depuis que la FDA a publié, en 2004, l’initiative visant à promouvoir le développement et l’implantation de technologies d’analyses de procédé (PATs), de nombreux groupes de recherche ont prouvé qu’un suivi et un contrôle adéquat des procédés rendait possible la relâche des produits en temps réel, ouvrant ainsi la voie à la production en mode continu. Dans ce contexte, cette étude présente la conception de systèmes d’analyse et de contrôle en ligne visant à assurer, en temps réel, la qualité d’un produit pharmaceutique intermédiaire fabriqué en mode continu. Le produit visé est une solution d’enrobage pour comprimés pharmaceutiques, utilisée à des fins esthétiques et afin de protéger le comprimé de l’environnement, laquelle est préparée par mélange d’eau et de divers composants disponibles commercialement sous forme d’un pré-mélange de poudre. Les attributs critiques de qualités (CQAs) de la solution ont d’abord été identifiés grâce aux connaissances du produit et du procédé. Par la suite, un certain nombre d’outils d’analyse de procédé ont été évalués pour leur capacité à analyser et à suivre ces attributs en ligne. Les outils sélectionnés ont ensuite été intégrés à l’unité pilote de préparation de solution d’enrobage en continue (UPSEC), laquelle a été étudiée afin de déterminer les paramètres critiques du procédé (CPPs). Des relations mathématiques établies entre les CQAs et les CPPs sont au coeur du système de contrôle en ligne qui sera implanté sur l’unité pilote. Au final, cette étude devrait fournir une preuve de concept, pour l’industrie pharmaceutique, d’un système d’analyse et de contrôle en ligne de la qualité pour un produit ayant été préparé en mode continu.

Efficacité technique, productivité et compétitivité des principaux pays producteurs de coton / Technical efficiency, productivity and competitiveness of the main countries producing cotton

Djimasra, Nodjitidjé 18 December 2009 (has links)
Cette thèse étudie l’efficacité technique, la productivité et la compétitivité des principaux pays producteurs de coton. Un premier chapitre décrit la compétitivité internationale de façon générale et les stratégies commerciales pratiquées. Les structures productives en Afrique Subsaharienne sont traitées au deuxième chapitre, car considérées comme les plus faibles. Le secteur du coton étant retenu comme cadre d’étude au troisième chapitre. Une étude économétrique est faite afin de mettre en exergue les déterminants de la performance à l’exportation du coton. Les deux derniers chapitres portent sur l’analyse et la mesure de l’efficacité technique et la productivité globale des facteurs tant théoriques qu’empiriques. La méthode d’enveloppement des données est mise en évidence suivie d’une analyse économétrique. Cette étude est réalisée afin de mettre en place une politique de production efficace et de compétitivité. A cette fin, elle propose un nouveau visage organisationnel en termes d’implications de politiques économiques pour contribuer à revitaliser le secteur cotonnier considéré comme moteur du développement économique en Afrique. / This thesis aims to study the technical efficiency, the productivity and the competitiveness of the main cotton producing countries. In a first chapter, it describes globaly the international competitiveness and the practised commercial strategies. The productive structures in Sub-Saharan Africa are examined in the second chapter, because they are considered as the weakest. The third part deals with the branch of the coton. An econometric study is led in order to highlight the determiners of the performance in the cotton export. The last two chapters concern the analysis and the measurement of the technical efficiency and the global productivity of theoretical and empirical factors. The method of the data envelope is revealed, followed by an econometric analysis. This study is realized to set up a policy of effective production and competitiveness. In this purpose, she proposes a new organizational face in the implication of economic policies to contribute to revitalize the cotton branch, which is considered as a driving element of the economic development in Africa.

Development of Production Concept : Process development at ABB Control Products with focus on generating new production concept

Anderstig, Sandra, Eklund, Daniel January 2012 (has links)
This Master thesis is within the area of innovative production. The authors are Master students at Mälardalen University in the field of production and process development. The purpose of the thesis is to design a production development process and to apply it in the case study performed at ABB Control Products in Västerås, Sweden. The new production concept developed is needed due to several changes in production of large size contactors that will take place during 2012; a new product size will be introduced, a new design of current products will be implemented, and production capacity for future increasing demands must be investigated. The approach to generate the production concept has been based on theoretical methods and models with focus on the lean philosophy. Through the theoretical framework a process for production development has been designed with the stages; Planning and Preparation, Current State Analyze, Concept Generation, Concept Analyze and Selection, and Visualization of Concept. The outcome of the thesis project is a mapping and disturbance analyze of current production, and a new production concept with an automation solution and a new balancing of the production line included. Finally the new production concept has been visualized in a 3D-simulation model. The main differences of the new production concept compared to current production is that conveyors are used as transportation system through the entire production process and two parallel flows is used in the production line in aim to shorten the lead time.

Green and Lean Production Visualization Tools; A Case Study exploring EVSM /

Darvish Shahrbabaki, Shahab Aldin January 2011 (has links)
There is a great need for an environmental, economic and social sustainable society, meeting the needs of the present without compromising the ability of future generations. Focusing on environmental sustainability, legislation and industrially accepted emission targets have emerged, on an overall level represented by e g the Kyoto protocol. Green as well as Lean production has thus become a more and more important topic in recent years. Based on the gigantic need for technologies and strategies that will reduce CO2 emissions globally, as well as customer demands for cost efficient and environmental friendly goods and processes, companies are starting to change their principles towards Green and Lean philosophies. In Green and/or Lean development, like other systematic approaches towards improved processes, there is a need for visualization tools to be used to analyze the supply chain and the manufacturing system. One possible visualization tool for this purpose is Environmental Value Stream Mapping, which has all the characteristics of its parent, VSM (Value Stream Mapping) and additional kaizen elements. In the EVSM, the environmental issues and the usage of material or energy have been added to the established VSM tool. However it has been almost four years since United States Environmental Protection Agency (USEPA) has introduced EVSM and there is no reliable evaluation how this tool really works and can be implemented. Therefore there is a need to evaluate and possibly improve this tool, based on practice and the applicability in industry. A case study has been performed testing the EVSM tool in industry and is presented in this paper. The aim of the case study is to analyze how the EVSM tool can be used as well as implementing suggested changes, summarized into, an Environmental Flow Process Chart. The EVSM tool seems suitable for showing the parts of the process in the supply chain which has more waste of energy or material. Still, it lacks information about where and how this waste are generated and which element of the process that is making the most waste, indicating a need for improvement
