This dissertation discusses the application of additive manufacturing technologies for production of a large-scale rapid prototyping machine, which will be used to produce moulds for prototype composite turbine blades for the emerging renewables energy industry within the Eastern Cape region in South Africa. The conceptualization and design of three complete printer builds resulted in the amalgamation of a final system, following stringent theoretical design, simulation, and feasibility analysis. Following the initial product design cycle stage, construction and performance testing of a large-scale additive manufacturing platform were performed. In-depth statistical analysis of the mechatronic system was undertaken, particularly related to print-head locational accuracy, repeatability, and effects of parameter variation on printer performance. The machine was analysed to assess feasibility for use in the mould-making industry with accuracy and repeatability metrics of 0.121 mm and 0.156 mm rivalling those produced by some of the more accurate fused deposition modellers commercially available. The research data gathered serves to confirm that rapid prototyping is a good alternative manufacturing method for wind turbine blade plug and mould production.

A busca por ritmar a produção e nivelar os recursos, ainda na etapa de planejamento, visa facilitar as tomadas de decisões no canteiro de obras. Este estudo analisa o planejamento de empreendimentos habitacionais repetitivos destacando situações que identificam gargalos futuros de produção no canteiro de obras. Dois estudos de caso foram realizados em condomínios residenciais repetitivos. As medições mensais dos serviços executados no primeiro estudo de caso e os problemas encontrados serviram de embasamento para a elaboração do planejamento do segundo estudo. Analisando os fluxos físicos das atividades a serem desenvolvidas, utilizando a técnica de Linhas de Balanço como ferramenta, e tomando-se ações corretivas na fase de planejamento destas, as perdas inerentes ao processo produtivo na construção civil poderão ser reduzidas. / Abstract: The construction industry faces a phase of adequacy to the country's financial reality, where the improvement in the production is requisite to reduce costs and to keep the company competitive. The search for balance the production and leveling the resources, during the planning, aims to facilitate the taking of decisions during the construction. This study analyzes the planning of repetitive enterprises detaching situations that identify future problems of production during the construction. Two studies of case had been carried through in repetitive residential condominiums. The monthly measurements of the services executed in the first study of case and the joined problems had served of basement for the elaboration of the second study of case planning. Analyzing the physical flows of the activities to be developed, using the technique of Lines of Balance as tool, and taking corrective actions in the phase of planning of these, the inherent losses of the productive process in the civil construction could be reduced. / Mestrado / Edificações / Mestre em Engenharia Civil

This thesis presents a cost allocation method for deriving lower bounds on costs of feasible policies for a class of production/inventory problems. Consider the joint replenishment problem where a group of items is replenished together or individually. A sequence of reorders for any particular item will incur holding, backorder and set-up costs specific to the item, in addition whenever any item is replenished a joint cost is incurred. What is required of the total problem is the minimization of a cost function of the replenishment sequence or policy. The cost allocation method consists of decomposing the total problem into sub-problems, one for each item, by allocating the joint cost amongst the items in such a way that every item in the group receives a positive allocation or none. The result is that, for an arbitrary feasible cost allocation, the sum of the minimum costs for the subproblems is a lower bound on the cost of any feasible policy to the total problem. The results for the joint replenishment problem follows: For the constant and continuous demand case we reproduce the lower bound of Jackson, Maxwell and Muckstadt more easily than they did. For the multi-item dynamic lot-size problem, we generalize Silver-Meal and part-period balancing heuristics, and derive a cost allocation bound with little extra work. For the 'can-order' system, we use periodic policies derived from the cost allocation method and show that they are superior to the more complex (s,c,S) policies. The cost allocation method is easily generalized to pure distribution problems where joint replenishment decisions are taken at several facilities. For example, for the one-warehouse multi-retailer problem, we reproduce Roundy's bound more easily than he did. For the multi-facility joint replenishment problem (a pure distribution system with an arbitrary number of warehouses), we give a lower bound algorithm whose complexity is dr log r where d is the maximum number of facilities which replenish a particular item and r is the number of items. / Business, Sauder School of / Graduate
