A importância dos serviços para as empresas de manufatura tem aumentado nas últimas décadas em função das alterações no ambiente em que estão inseridas. Dentre os aspectos relacionados com a oferta de serviços por empresas de manufatura, pode ser citado que os serviços são influenciados pelas definições realizadas durante o processo de desenvolvimento de produtos (PDP). No entanto, a literatura ainda é escassa no sentido de compreender essa relação. Dessa forma, o objetivo do presente trabalho é analisar as características dos serviços relacionados com os produtos e a sua relação com o PDP por meio de um estudo de caso em uma empresa do setor aeroespacial. Os dados foram coletados por meio de uma análise documental e entrevistas semi-estruturadas, em que foi feita a descrição das etapas do PDP, o levantamento e classificação do portfolio de serviços, a análise detalhada dos serviços selecionados e a análise da relação entre estes serviços e o PDP. Os resultados da análise confirmaram que os serviços são impactados pelas decisões de todas as etapas do PDP e para todos os serviços analisados e ainda apresenta quando e como essas relações acontecem. Os resultados obtidos foram comparados com a literatura existente. As relações identificadas influenciam diversos aspectos dos serviços analisados, como: o processo, o escopo, a infraestrutura, os custos e pessoas. / The importance of services to manufacturing companies has grown over the last decades due to several changes in the business environment. Among the aspects related with the offer of services by manufacturing companies is the fact that services are influenced by the decisions taken during the new product development process (NPD). Although, the literature is scarce when it comes to comprehend how this relationship happens. In this way, the objective of this study is to analyze the characteristics of product-related services and the relationship between the NPD process activities and these services through a case study in a manufacturing company of the aerospace industry. The data was collected with the use of a documentary analysis and semi-structured interviews, where the phases of the NPD were described, the service portfolio was identified and classified, the selected services were analyzed and the relationship between the NPD and these services. The results confirmed that all the services that were analyzed are influenced by the decisions of all NPD phases and maps it out. The results were then compared with the existing literature. The identified relationship influence several aspects of the services that were analyzed, such as: the process, the scope, the infrastructure, the costs and people.

Product development process (PDP) architecture holds the key to the management of New Product Development (NPD). A lot of care is exercised in managing the NPD to reduce risk and uncertainties. There exists potential scope for improvement both in initial planning as well as execution of the NPD program by studying the PDP architecture. This research work seeks to taps this potential and presents an analytical tool to aid the NPD Managers. In this research work Design Structure Matrices (DSM) are used to represent the PDP architecture. The Work Transformation Matrix (WTM) is a kind of DSM and it was introduced for the analysis of concurrent task structures. However a generalized task structure has not been studied analytically in the literature. In order to study a generalized task structure we add two new matrix types to the WTM set to represent the task network interconnections and the task interdependence. First we study the pure sequential task iteration structure for NPD and show that it has lower engineering effort (cost and time) than the concurrent task iteration structure previously discussed in literature. Next we study the generalized task iteration structure and derive the expressions for total work and cost vectors. This is a major research contribution since only simulation based methods are currently available for studying generalized task iteration structures. The optimization of sequencing interdependent tasks is a well known NP hard problem in NPD literature. For small sized task sets, exhaustive enumeration of all possible sequencing and their corresponding time or cost vectors can be computed to determine the optimal sequence. However for large sized task networks, only heuristic methods are deployed. Using the closed form expression for cost and time vectors for a pure sequential task iteration structure derived earlier in this research work, we attempt to devise a method to optimally sequence the design tasks. We develop new matrix combining both the node and link weightages of task network. Using the time vector relationship between sequential and concurrent task structures, it is shown that the optimal task sequence corresponds to the reordering of this combined matrix whose “Dominance index” (sum above the diagonal) is minimum. Finally, we use some of the standard test cases from the PDP literature to demonstrate our research findings.

L'auto-assemblage des copolymères à bloc (CPBs) attire beaucoup d'intérêt grâce à leur capacité de générer spontanément des matériaux ordonnés avec des propriétés uniques. Les techniques Langmuir-Blodgett (LB) et Langmuir-Schaefer (LS) sont couramment utilisées pour produire des monocouches ou des films ultraminces à l'interface air/eau suivi de transfert aux substrats solides. Les films LB/LS de CPBs amphiphiles s'auto-assemblent dans des morphologies variables dépendamment de la composition du CPB ainsi que d'autres facteurs. Dans notre travail, nous avons étudié les films LB/LS de polystyrène-b-poly(4-vinyl pyridine) (PS-P4VP) et leurs complexes supramoléculaires avec le naphtol (NOH), l'acide naphtoïque (NCOOH) et le 3-n-pentadécylphenol (PDP). La première partie de ce mémoire est consacré à l'investigation du PS-P4VP complexé avec le NOH et le NCOOH, en comparaison avec le PS-P4VP seul. Il a été démontré qu'un plateau dans l'isotherme de Langmuir, indicatif d'une transition de premier ordre, est absent à des concentrations élevées des solutions d'étalement des complexes. Cela a été corrélé avec l'absence de morphologie en nodules avec un ordre 2D hexagonal à basse pression de surface. L'ordre au-delà de la pression de cette transition, lorsque présente, change à un ordre 2D carré pour tout les systèmes. La deuxième partie du la mémoire considère à nouveau le système PS-P4VP/ PDP, pour lequel on a démontré antérieurement que la transition dans l'isotherme correspond a une transition 2D d'un ordre hexagonal à un ordre carré. Cela est confirmé par microscopie à force atomique, et, ensuite, on a procédé à une étude par ATR-IR des films LB pour mieux comprendre les changements au niveau moléculaire qui accompagnent cette transition. Il a été constaté que, contrairement à une étude antérieure dans la littérature sur un autre système, il n'y a aucun changement dans l'orientation des chaînes alkyles. Au lieu de cela, on a découvert que, aux pressions au-delà de celle de la transition, le groupe pyridine, qui est orienté à basse pression, devient isotrope et qu'il y a une augmentation des liaisons hydrogènes phénol-pyridine. Ces observations sont rationalisées par un collapse partiel à la pression de transition de la monocouche P4VP, qui à basse pression est ordonné au niveau moléculaire. Cette étude a mené à une meilleure compréhension des mécanismes moléculaires qui se produisent à l'interface air/eau, ce qui fournit une meilleure base pour la poursuite des applications possibles des films LB/LS dans les domaines de nanotechnologie. / Self-assembly of block copolymers (BCPs) attracts much interest due to their ability to spontaneously generate ordered materials with unique properties. For many applications, such as masks in nanolithography, separation membranes in medical diagnostics, and nanotemplates for nanowire fabrication, manufacturing into thin films is required. The Langmuir-Blodgett (LB) and Langmuir-Schaefer (LS) techniques are commonly used to produce ultrathin or monolayer films at the air/water interface that are transferred to solid substrates. LB/LS films of amphiphilic BCPs self-assemble into various morphologies, depending on the BCP composition and other factors. In our work, we investigated LB/LS films of polystyrene-b-poly(4-vinyl pyridine) (PS-P4VP) and their supramolecular complexes with, naphthol (NOH), naphthoic acid (NCOOH) and 3-n-pentadecylphenol (PDP). The first part of the thesis was devoted to the investigation of PS-P4VP complexes with NOH and NCOOH, in comparison to PS-P4VP alone. It was shown that a plateau in the Langmuir isotherm, indicative of a first-order transition, is absent at high spreading solution concentrations for the complexes. This was correlated with an absence of the expected dot morphology with 2D hexagonal-like order at low surface pressure. Above the transition, when present, the morphology has 2D square order. The second part of the thesis re-examines the PS-P4VP/PDP system, which was previously shown to undergo a transition from 2D hexagonal to square order at the isotherm plateau pressure. This was confirmed here, and a detailed ATR-IR study of LB films was then undertaken to better understand molecular-level changes occurring at this transition. It was found that, contrary to another study in the literature on a different system, there is no change in alkyl chain orientation. Instead, it was found that the pyridine group loses its low-pressure orientation and there is increased phenol-pyridine hydrogen-bonding above the transition pressure, which is rationalized by a partial collapse of the low-pressure molecularly ordered P4VP monolayer at the transition pressure. This study leads to an improved understanding of the processes occurring at the air/water interface, which is a basis for the further possible applications of LB/LS films in nanotechnologies.

O presente trabalho apresenta um modelo de aplicação de ferramentas de projeto integradas ao longo das fases de desenvolvimento de produto, neste caso, aplicadas na melhoria do produto suporte para fixação de cilindro de gás natural veicular. O foco do trabalho é apresentar a integração de ferramentas nas fases de Projeto Informacional, Projeto Conceitual e Projeto Detalhado do Processo de Desenvolvimento de Produtos. Entende-se por integração a escolha de ferramentas que permitam conduzir o fluxo de informação ao longo das fases de desenvolvimento de produtos, de tal forma que a informação de saída de uma ferramenta seja a informação de entrada da ferramenta subseqüente. As ferramentas integradas a partir da fase de Projeto Informacional foram a Pesquisas de Mercado Qualitativa e Quantitativa, com a finalidade de identificar as demandas dos clientes. As demandas dos clientes foram os dados de entrada da Matriz da Qualidade (Quality Function Deployment - QFD), resultando nos requisitos do produto e suas respectivas especificações-meta. A partir dos requisitos do produto, diferentes conceitos (configurações) foram gerados, apoiados pela Matriz Morfológica no Projeto Conceitual. Na seqüência utilizou-se a ferramenta de Projeto de Experimentos (Design of Experiments - DOE) para avaliar a estimativa de preço frente às possíveis configurações do produto. Com a Matriz de Pugh, alternativas de conceito de produto foram avaliadas possibilitando a escolha do melhor conceito de produto. No Projeto Detalhado, foi aplicada ferramenta de Análise dos Modos de Falha e seus Efeitos (Failure Mode and Effects Analysis - FMEA), utilizado de forma integrada com o QFD, para identificar as falhas atuais e potenciais e seus efeitos em sistemas e processo. Em função das demandas identificadas, foram definidas e implementadas melhorias no produto. Observou-se a adequabilidade destas ferramentas de projeto para aplicação de forma integrada, garantindo um fluxo contínuo de informações rastreáveis e que tendem a levar à uma reduzida chance de perdas ao longo do processo. / There are few examples in literature about the integration of project tools along the product development phases. The main research objective in thesis is to integrate some tools that facilitate the information flow along the product development phases, more specifically in Informational Project, Conceptual Project and Detailed Project phases. The product improvement “support for Vehicular Natural Gas” was the object of study in thesis. The main idea is that the information output from one tool is the input information of the subsequent tool. Starting from the Informational Project phase it was performed qualitative and quantitative market researches with the purpose of identifying the customers' demands for the studied product. The customers’ demands were the entrance data of the QFD (Quality Function Deployment) tool resulting in the product requirements and their respective specifications-goal. In Concept Project the product requirements were converted in functions and further different concepts were generated through the Morphologic Analysis. In the sequence, it was used the DOE (Design for experiments) tool to evaluate the estimate price to the possible products' configurations. The Pugh Matrix tool was used for concepts evaluation and choice. The FMEA (Failure Mode and Effects Analysis) tool integrated with QFD was useful for current and potential failures identification and impact analysis in the system and process. With the application of these five tools the users’ demands were identified and improvements to the product were performed. The chosen tools proved to be adequate for integration, assuring that a continuous trackable information flow was attained with presumable reduced information loss, along the Product Development Process phases.

An investigation into the impact of generalised maximum entropy solutions on the study of queues with or without arrival balking and their applications to congestion management in communication networks Keywords: Queues, Balking, Maximum Entropy (ME) Principle, Global Balance (GB), Queue Length Distribution (QLD), Generalised Geometric (GGeo), Generalised Exponential (GE), Generalised Discrete Half Normal (GdHN), Congestion Management, Packet Dropping Policy (PDP) Generalisations to links between discrete least biased (i.e. maximum entropy (ME)) distribution inferences and Markov chains are conjectured towards the performance modelling, analysis and prediction of general, single server queues with or without arrival balking. New ME solutions, namely the generalised discrete Half Normal (GdHN) and truncated GdHN (GdHNT) distributions are characterised, subject to appropriate mean value constraints, for inferences of stationary discrete state probability distributions. Moreover, a closed form global balance (GB) solution is derived for the queue length distribution (QLD) of the M/GE/1/K queue subject to extended Morse balking, characterised by a Poisson prospective arrival process, i.i.d. generalised exponential (GE) service times and finite capacity, K. In this context, based on comprehensive numerical experimentation, the latter GB solution is conjectured to be a special case of the GdHNT ME distribution. ii Owing to the appropriate operational properties of the M/GE/1/K queue subject to extended Morse balking, this queueing system is applied as an ME performance model of Internet Protocol (IP)-based communication network nodes featuring static or dynamic packet dropping congestion management schemes. A performance evaluation study in terms of the model’s delay is carried out. Subsequently, the QLD’s of the GE/GE/1/K censored queue subject to extended Morse balking under three different composite batch balking and batch blocking policies are solved via the technique of GB. Following comprehensive numerical experimentation, the latter QLD’s are also conjectured to be special cases of the GdHNT. Limitations of this work and open problems which have arisen are included after the conclusions.

>Magister Scientiae - MSc / A novel monomer (Phenazine-2,3-diimino(pyrrole-2-yl)–PDP) derived from the condensation reaction between 2,3-diaminophenazine and a pyrrole derivative has been synthesized as a hinge molecule in the design of a zig-zag polymer with actuation possibility. The monomer was polymerized chemically and electrochemically to produce the new polymer material – polymerized Phenazine-2,3-diimino(pyrrole-2-yl) PPDP. Two very crucial properties of a good actuator material, relate specifically to its solubility testing and electrical conductivity. The hinged polymer material was studied intensively in terms of its spectroscopy; Fourier Transform Infrared - FTIR, 1H’NMR, thermal properties (Differential Scanning Calorimetry-DSC and Thermogravimetric Analysis-TGA) as well as voltammetry and conductivity. Conductivity was evaluated using three different approaches including; 4 probe measurements, plotting of I/V curves based on potentiostatic measurements and an electrochemical impedance experiment using a dielectric Solartron interface. Electrochemical kinetics of the polymer prepared as a thin film at glassy carbon electrode (GCE) was also done and it was clear that the thin film conductivity was vastly different from the compressed pellet conductivity (thick film). The zig-zag polymer was then further modified by homogeneous inclusion of gold nanoparticles to improve conductivity and solubility, in the thick film arrangement. Conductivity of the thin film was studied by electrochemical impedance spectroscopy with the relative charge transfer values being determined for unmodified and modified polymer systems. The solubility testing of the material plays an important role as it is required for a wide range of experimental applications. The zig-zag polymer showed great promise for applications; in dye sensitized solar cells and free standing interpenetrating polymer network (IPN), solubility testing and electrical conductivity would need to be improved in order to be used in these applications.
