Ces dernières années, la conception de produit vise de plus en plus à remettre le client aucentre du processus de développement. De nouvelles méthodes et outils ont permis de formaliser nonseulement l’identification des besoins et des attentes du client mais également leur transformation enexigences. Cependant, malgré les progrès récemment apparus dans ce domaine, la notion de valeurperçue par le client qui est associée au produit reste faiblement considérée durant le développement duproduit alors que la perception de cette valeur par le client va jouer un rôle clé au moment du choix duproduit.Dans cette thèse, nous proposons une approche normative visant l’intégration de la notion devaleur du produit dans le processus d’établissement des exigences. Un état de l’art présente lesconcepts et les pratiques impliqués dans le déploiement de la fonction de qualité, étroitement liée auprocessus de spécification des exigences basé sur la valeur. Ces concepts sont relatifs aux notionsd’objectifs, de modèles de la valeur, de fonctions d’utilité multi attributs et de hiérarchie et de réseauxd’objectifs.Notre approche se déroule en 4 étapes : (1) identifier et structurer les objectifs à partir del’expression des attentes du client, (2) spécifier les attributs de la valeur perçue par le client etconstruire un modèle de la valeur client, (3) transformer les objectifs en exigences pour construire unmodèle global de la valeur produit et (4) dériver ce modèle global en un modèle de la valeur pourchaque composant du produit. Cette approche permet ainsi de prendre en compte explicitement lavaleur produit perçue par le client en l’intégrant dans les phases de développement, ce qui favorise uneconception proactive dirigée par la valeur.Nous l’illustrons sur un exemple d’avion de ligne développé en Vanguard Studio. Cet exemplea été élaboré par l’ensemble des partenaires au cours du projet Européen IST CRESCENDO et sert decas-test pour ce projet / Recently customer-based product development is becoming a popular paradigm. Customer needsand expectations are identified and transformed into requirements in systematic processes for productdesign with the help of various methods and tools. However, in many cases, these approaches fail tofocus on the perceived value that is crucially important when customers make the decision ofpurchasing a product. The requirements specification derived from these approaches are typicallyvalue-implicit.In this thesis, a prescriptive approach to derive value-based requirements specification is proposedby integrating the concept of value into the house of quality of quality function deployment. Anintegrated set of theories, methods and concepts is introduced in order to mitigate the sevenmethodological problems of house of quality regarding to establishing appropriate value-basedrequirements specification. The foundations of the approach include concepts of objective, valuemodel and consequence model, methods of means-ends objectives network, fundamental objectiveshierarchy, response surface methodology and value-driven design, and theory of multi-attribute utilitytheory. The procedure of the approach is a four-step process: (1) identify and structure objectives frominitial customer statements of expectations, (2) specify attributes and construct customer value model,(3) transform fundamental objectives into engineering characteristics to construct system value model,and (4) derive component value models from system value model. Through this procedure, initialcustomer statements can be reasonably derived into customer value model, system value model andcomponent value model. The benefits of the approach are that it enables (1) reasonably qualifying andquantifying customer value, and performing value modeling and simulation, (2) perceived customervalue being subsequently used reactively for design evaluation, and proactively for value-drivendesign.The approach is applied in the context of a European Community’s R&D project CRESCENDO tohelp constructing airlines’ group value model for commercial aircraft development. This applicationfocuses on the first two-steps of the approach, and the value models are implemented in businesssoftware Vanguard Studio

Para superar os desafios existentes na produção citrícola, relacionados ao dinamismo do mercado, às pressões fitossanitárias e à complexidade da produção, deve-se ter um elevado nível de conhecimento do processo produtivo que conduza à tomada de decisão adequada. Este conhecimento pode ser obtido pela compreensão de como os requisitos da produção, representados pela qualidade exigida, são afetados pelas variáveis do processo, representadas por características técnicas. Considerando-se que esta compreensão auxilia na manutenção e competitividade da cultura, o presente trabalho tem como objetivo identificar, sistematizar e priorizar as características técnicas para atender as exigências do processo de produção de laranjas destinadas à indústria processadora de suco. A identificação da qualidade exigida do processo e das características técnicas da produção foi realizada por meio de pesquisa bibliográfica. Identificou-se 38 itens da qualidade exigida, com base em 6 processos e 17 atividades realizadas para a produção de laranjas, e 114 características técnicas que afetam esta produção, organizadas em 7 grupos de afinidades. O método do desdobramento da função qualidade (QFD) foi utilizado para compreender a relação entre as qualidades exigidas e as características técnicas da produção, permitindo a sistematização. A aplicação do método também permitiu a priorização das características técnicas, em uma etapa denominada conversão. A priorização foi definida com base em um peso relativo calculado para cada característica na etapa de conversão, que representa a influência de cada uma sobre o processo produtivo. Do total de 114 características, 64 (56%) foram responsáveis por 80% do peso relativo total calculado. Notou-se que a influência de cada característica sobre o processo produtivo é diferente, apesar dessa relação não atender ao princípio de Pareto. A matriz de correlação, que identifica a relação de interdependência entre as características técnicas da produção, expôs ainda mais a complexidade e o caráter sistêmico da produção citrícola. / In order to overcome citriculture\'s challenges, related to market dynamics, phytosanitary pressures and production complexity, a high level of knowledge concerning the production process is necessary, leading to proper decision making. This knowledge can be achieved by comprehension on how the production requirements, represented by demanded quality, are affected by process variables, represented by technical characteristics. Considering that this comprehension helps to maintain proper condition and competitiveness of citriculture, this study aims to identify, systematize and prioritize technical characteristics to satisfy the requirements of the orange production process to attend juice industry. The identification of process quality demanded and technical measures was performed by bibliographical research. It was identified 38 items of demanded quality, based on 6 process and 17 activities performed on oranges production, and 114 technical characteristics that affect such production, organized into 7 affinity groups. Quality function deployment (QFD) method was applied in order to understand the relationship between quality demanded and technical characteristics, leading to systematization. This method also enabled prioritization of technical characteristics, in a process named conversion. The prioritization was based on relative weight, calculated for each characteristic in conversion process. This weight represents the influence of the characteristic on production process. From the total of 114 characteristics, 64 (56%) were responsible for 80% of total relative weight calculated. It was noted that the influence of each characteristics on production process were different, although this relationship does not answer to Pareto principle. The correlation matrix, that identifies the interdependence relationship between technical characteristics, exposed the complexity and systemic nature of citriculture.

Vorbeugende QM-Techniken operationalisieren die Funktionen des Qualitätsmanagements (QM) mit dem Ziel einer abgesicherten Produktentstehung. Sie leisten einen wesentlichen Beitrag zur Erhöhung der Produktqualität. Jedoch zeigen Untersuchungen, dass deren Einsatz häufig sehr große Probleme bereitet. Die vorliegende Arbeit untersucht vordergründig die FMEA, QFD und DRBFM. Neben der Beschreibung ihrer Anwendungsbereiche, werden die Vorteile und Schwächen gegenübergestellt. Es gilt, die Schwächen mit Hilfe einer neu entwickelten Methode zu umgehen bzw. zu eliminieren. Die Entwicklung zentraler Schwerpunkte zur Erreichung von Null-Fehlerqualität liefert die Basis für die Erstellung einer Checkliste in Form eines Fragenkataloges. Ziel soll es sein, durch die Systematik des Fragenkataloges und Wahl des Antwortformates Fehlerursachen zu vermeiden.

Thesis (MScEng)-- Stellenbosch University, 2013. / ENGLISH ABSTRACT: It has been postulated that lean thinking principles can be successfully applied to any industry. Following on that postulation, there have been great advances in the area of lean thinking outside the “traditional” domain of manufacturing. One such advancement has been in the area of maintenance operations where lean thinking has been used through the concept of lean maintenance. However, a problem lies in the fact that the work that has been done so far has been largely limited to the manufacturing environment where lean maintenance is practised as a prerequisite for lean manufacturing. Little evidence exists of the use of frameworks or models that can test, let alone apply, lean thinking in operational maintenance environments outside of the manufacturing context. The main objective of this research was to come up with a framework, based on lean thinking tools and relevant performance measures, which will prove the applicability or otherwise, of lean thinking in an operational maintenance environment outside the traditional domain of manufacturing. A case study of the rolling stock section of the Salt River depot of PRASA, Metrorail, which is a typical non-traditional domain for lean thinking, was used to build and verify the framework. The Analytic Hierarchy Process (AHP) together with the Quality Function Deployment (QFD) process, is used in building and quantifying the judgements made in developing elements of the framework. The Value Stream Management process is used to predict the possible outcomes of using the proposed framework in the case study. The study was based on the hypothesis that lean thinking can also be applicable to non-manufacturing oriented maintenance organisations. The ensuing framework is used to make the argument for the use of the lean thinking approach in non-manufacturing oriented maintenance environments and hence expand the body of knowledge in this subject area. It also provides a roadmap for PRASA, Metrorail and other similar maintenance organisations in the rail industry to streamline and improve current operations through value addition and waste elimination efforts. / AFRIKAANSE OPSOMMING: Daar word bespiegel dat die beginsels van besparende denke (“lean thinking”) suksesvol toegepas kan word op enige industrie. As gevolg van hierdie hipotese is daar groot vooruitgang op die gebied van besparende denke buite die “tradisionele” gebied van vervaardiging. Een sodanige vooruitgang is op die gebied van die verrigting van instandhouding waar besparende denke bekend is as die konsep van “lean maintenance”. Die problem is dat die vooruitgang tot dusver beperk is tot die vervaardigingsomgewing waar besparende instandhouding beskou word as ‟n vereisde vir besparende vervaardiging. Daar word min gebruik gemaak van raamwerke of modelle om besparende denke te toets of om dit toe te pas in instandhoudingsomgewings buite die vervaardigingskonteks. Die hoofdoelwit van hierdie navorsing is om te vore te kom wet ‟n raamwerk wat gegrond is op besparende denke en relevante prestasie maatstawwe, en wat die toepaslikheid van besparende denke , al dan nie, op die verrigting van instandhouding buite die tradisionele gebied van vervaardiging sal bewys. ‟n Gevalle studie van die Soutrivier Depot van PRASA Metrorail, wat tipies is van ‟n nie-tradisionele gebied vir besparende denke, is gebruik vir die bou en stawing van die raamwerk. Die analitiese hiëragiese proses (AHP) tesame met die kwaliteits funksionele ontplooiing (QFD) proses word gebruik in die kies van elemente vir die raamwerk. Die waarde stroom bestuursproses word gebruik om die moontlik uitkomste van die gebruik van die voorgestelde raamwerk, te voorspel. Die studie is gegrond op die hipotese dat besparende denke ook toegepas kan word op nie-vervaarding-georienteerde instandhoudingsorganisasies. Die raamwerk word gebruik om te bewys dat die besparende denke benadering gebruik kan word in nie-vervaardiging–georienteerde instandhoudingsomgewings en dus kennis hieroor uit te brei. Die raamwerk kan ook gebruik word as ‟n padkaart deur Metrorail en ander soortgelyke instandhoudingsorganisasies in die spoorweg industrie, om hulle huidige werksverrigting deur waarde toevoeging te verbeter en om verkwisting te voorkom.

O surgimento do café espresso e a popularização do cappuccino promoveu a conquista de novos produtos e novos espaços para produtos com café. Durante um processo de desenvolvimento, é importante levar em consideração características ou atributos de qualidade, que o cliente espera do produto final. Neste contexto, o método de Desdobramento da Função Qualidade (QFD) é uma ferramenta utilizada para ouvir, traduzir e transmitir, a voz do cliente para dentro da empresa. Outra ferramenta de fundamental importância para o desenvolvimento de produtos é o planejamento de experimentos, pois, permite que as formulações desenvolvidas, estejam de acordo com as especificações solicitadas, de modo a atingir as condições otimizadas de um processo, ou avaliar os efeitos que os fatores têm nas respostas desejadas. O objetivo deste trabalho foi estabelecer uma metodologia de desenvolvimento para misturas com café solúvel (cappuccinos) aplicando a ferramenta de desdobramento da função qualidade (QFD) e o planejamento de experimentos utilizando a Metodologia de Superfície de Resposta Triangular. Neste trabalho foi apresentado um modelo, aplicando a metodologia de QFD no desenvolvimento de misturas, para melhor compreender as expectativas e exigências do consumidor em relação a este produto. Foi apresentada a casa da qualidade, com todas as informações necessárias para o desenvolvimento do produto (requisitos cliente e do produto). No planejamento de experimentos, as variáveis independentes foram representadas pelos ingredientes cacau em pó, café solúvel e leite integral. As variáveis dependentes (respostas) foram obtidas através do teste sensorial de aceitação: aroma geral, aroma de café, sabor geral, sabor de chocolate, cremosidade, dissolução e impressão global. Para os atributos sabor de chocolate, dissolução, cremosidade e impressão global as proporções ótimas sugeridas corresponderam à formulação 1 do planejamento de experimentos. Já para os atributos aroma geral, aroma de café e sabor geral as porcentagens ótimas encontraram-se dentro das faixas estudadas para as variáveis leite em pó integral e café solúvel, no limite inferior destas faixas para a variável cacau em pó. O teste de preferência foi aplicado com a formulação 1, uma formulação sugerida para sabor geral e em um produto comercializado no mercado nacional; e resultou que a formulação desenvolvida pelo planejamento de experimentos foi a preferida entre os consumidores de cappuccino. Com os resultados obtidos é possível afirmar que a utilização das ferramentas propostas neste trabalho auxilia no desenvolvimento de misturas à base de café. / The commercialization of espress coffee and popularization of cappuccinos led to an increase on the development of new products with coffee. During the process of new products development, it is important to consider the final quality characteristics or attributes expected by the consumers. In this sense, the Quality Function Deployment (QFD) is a method used to hear, translate and transmit the client’s voice into the industry. Another tool of fundamental importance for the development of new products, is the experimental design, once it enables that the developed formulations are in accordance to the specifications required to achieve optimal conditions of a process, or evaluate the effects that some factors have over some desired responses. The objective of this work was to establish a methodology of development of mixtures with coffee (cappuccinos) applying the method of quality function deployment and experimental design using triangular surface response method. In this work it was presented a model as a result of the QFD analysis. The quality house was presented with all the information necessary for the product development (client and product requirements). For the experimental design, independent variables were represented by the ingredients: cocoa powder, soluble coffee and whole instant milk. The dependent variables (answers) were obtained by the acceptance sensorial analysis: overall flavor, coffee flavor, overall taste, chocolate taste, creaminess, dissolution and overall impression. For the attributes of chocolate taste, dissolution, creaminess and overall impression, the optimal proportions suggested corresponded to formulation 1 of the experimental design. For the attributes of overall flavor, coffee flavor and overall taste, the optimal percentages were within the limits studied for the variables instant milk and soluble coffee, and in the inferior limit of variable cocoa powder. Preference analysis was applied with formulation 1, one formulation considering overall taste attribute and one commercial sample. Results indicated that the formulation developed by the experimental design was the most preferred among participants. These results indicate that the use of the tools proposed in this work are useful on the development of mixtures based on soluble coffee.
