A abertura de mercado no Brasil, na década de 1990, aumentou a concorrência na indústria automobilística local e a busca por novos produtos, tecnologias e principalmente por processos de manufatura mais enxutos e viáveis economicamente. Dentro deste contexto, a pressão pela redução do tempo de desenvolvimento de novos produtos, fez com que fosse necessário reduzir também o tempo de desenvolvimento dos novos processos de manufatura. O desenvolvimento e planejamento de uma manufatura são processos complexos, pois envolvem diferentes áreas da empresa, demanda altos investimentos e envolve diferentes tecnologias. A Engenharia de Manufatura é a área da empresa responsável pelo planejamento, projeto e implantação de novas manufaturas para novos produtos. O objetivo central deste trabalho é a conceituação e aplicação da Simulação de Processos aplicada nas fases de planejamento e projeto para linhas de produção manuais e automatizadas através da utilização de ferramentas computacionais. O foco será na área de armação de carroceria onde se encontram o maior grau de automação e complexidade. As vantagens obtidas com sua utilização, nas fases de planejamento e projeto, são a redução de investimentos, redução no tempo de introdução de um novo processo, observação prematura de gargalos de produção, definição da quantidade necessária de estoques intermediários, os quais influenciam diretamente os tempos de processo e custos variáveis. Os conceitos apresentados são validados a partir de estudos de casos na Volkswagen do Brasil envolvendo veículos em lançamento como o novo Gol e Voyage e veículos em série como o Polo. / The market opening to newcomers in Brazil during the 1990s has increased the local automotive industry competition and the search for new products, technologies and mainly for leaner and financially feasible processes. Within that context, the need to reduce new product development timing has made it necessary to minimize the development period for manufacturing processes. Planning and developing manufacturing operations are complex processes, once they involve different areas in a company and they demand high investment and peculiar technologies. The Manufacturing Engineering is the area in the company that takes over the responsibility for planning, designing and implementing new manufacturing processes for new products. The main objective of that work is define concepts and apply the process simulation on the planning and designing steps of manual and automatic production lines by using computer tools. The target will be the body shop area where the automation and complexity degrees are higher. The advantages of using such tools during the planning and designing phases are not only the reduction of investment and process introduction timing but also the early identification of production bottlenecks, as well as the definition of line buffers that directly affect the process cycles and variable costs. The presented concepts are validated through cases of Volkswagen of Brazil and involving the launching of vehicles such as the new Gol and Voyage and series models like the Polo.

Problemas de sequenciamento são muito comuns, eles existem sempre que há uma escolha sobre a ordem em que várias tarefas podem ser realizadas. Seja o negócio uma companhia aérea, um hotel, um fabricante de computadores ou uma universidade, esses problemas fazem parte do cotidiano. A aplicação das técnicas de sequenciamento permite, por exemplo, a redução dos custos e o aumento na agilidade da cadeia de suprimentos, afetando as operações no inicio e no fim da cadeia de suprimentos pelo mundo inteiro. Este trabalho parte da intenção de abordar os princípios e as técnicas de Scheduling, com a finalidade de propor um modelo de sequenciamento para a solução de um problema em sistemas produtivos do tipo job shop com n tarefas e m máquinas, considerando os tempos de setup dependentes da sequência e tendo como horizonte de planejamento o curto prazo. O objetivo é o de minimizar a perda dos tempos não produtivos. Neste contexto, a pesquisa apresenta um enfoque tanto exploratório, quanto aplicado. Pode ser considerado exploratório, uma vez que a revisão da literatura é referência central para o desenvolvimento do modelo matemático. É aplicado considerando-se o desenvolvimento do modelo e avaliação de sua aplicabilidade. Sendo assim, a partir da definição do problema e desenvolvimento do modelo por meio do uso de técnicas matemáticas e abordagens da pesquisa operacional constatou-se que as conclusões tiradas podem inferir decisões para o problema real. Sendo que, as considerações aqui feitas têm por finalidade relatar os fatos constatados nos experimentos realizados, visando contribuir com futuras pesquisas na área. / Sequencing problems are very common, they happen every time there is a choice regarding the order in which several tasks can be performed. The business can be an airline, a hotel, a computer manufacturer or a university; these issues are part of their routine. The application of the sequencing techniques allows, for example, reducing the costs and fastening the supply chain all over the world. This work has an approach to Scheduling principles and techniques, with the objective of proposing a sequencing model for the solution of a problem in productive systems such as job shop with n tasks and m machines, considering setup times dependent on the sequence and adopting a short term planning. The goal is to minimize the waste of unproductive time. In this context, the research presents an approach both exploratory and applied. It can be considered exploratory, once that the literature review is a main reference to the development of a mathematical model. It is applied when we consider the development of the model and evaluation of its applicability. Thus, from the problem definition and the model development by the use of mathematical techniques and approaches of the operational research, we found that the conclusions drawn from the model might infer decisions for a real problem. The considerations shown here aim to report the facts given in the conducted experiments, intending to contribute to future researches in the area.

Em um ambiente produtivo, a falta de informações confiáveis cria, muitas vezes, uma imagem do chão-de-fábrica que não retrata a realidade, comprometendo o desempenho e diminuindo a agilidade da empresa. Neste contexto, um sistema de supervisão do chão-de-fábrica, capaz de fornecer informações confiáveis e de forma rápida, pode ser um grande diferencial para manter a competitividade das empresas de manufatura. Este trabalho sistematiza visões e conceitos que auxiliam na implantação de sistemas de supervisão do chão-de-fábrica em empresas que utilizam operações de usinagem no seu processo produtivo. Além disso, apresenta o desenvolvimento e a implantação deste sistema na Fábrica Integrada Modelo (FIM) do Núcleo de Manufatura Avançada (NUMA) da Escola de Engenharia de São Carlos - USP. / The lack of reliable information in a production environment creates a wrong image of the shop floor, affecting the plant\'s agility and its performance. A shop floor supervisory system, able to provide, in a fast way, that sort of information, can enhance the competitiveness of the manufacturing plant. The present work shows visions and concepts that can give support to the implementation of shop floor supervisory system in manufacturing plants. lt also presents the development and implementation of this kind of system in the lntegrated Model Plant (FIM) of the Advanced Manufacturing Nucleus (NUMA) at São Carlos - University of São Paulo.

Escalonamento de processos é um tipo de problema de otimização combinatória no qual devemos alocar máquinas à tarefas por períodos específicos de tempo. A literatura contém diversos estudos propondo técnicas para resolver modelos de escalonamento de processos como o job shop e o open shop. Esses modelos permitem que os passos no processo produtivo sejam ou completamente ordenados ou sem ordenação alguma. Com o aumento da complexidade das aplicações industriais no encontramos, mais recentemente, diversos trabalhos que propõe problemas de escalonamento de processos mais gerais para modelar mais precisamente os processos produtivos. O mixed shop, group shop e partial shop são exemplos de tais modelos. Nesse trabalho nós propomos uma busca tabu iterada para o partial shop, que é um modelo geral que inclui diversos modelos mais restritivos. Os componentes novos mais importantes da técnica são o gerador de solução inicial, a vizinhança e o limite inferior para a vizinhança. Em experimentos computacionais nós conseguimos demonstrar que a heurística genérica e única é capaz de competir, e as vezes superar, as técnicas de estado de arte desenvolvidas especificamente para partial, open, mixed e group shop. Algumas vezes uma máquina é o gargalo de um processo produtivo, e é replicada. Na literatura o caso das máquinas paralelas foi incluído em diversas extensões de problemas de escalonamento de processos. Nessa tese nós também propomos uma técnica para escalonar as máquinas paralelas, sem incluí-las explicitamente na representação do problema. Nós usamos técnicas gerais para os casos sem máquinas paralelas para produzir uma busca heurística tabu rápida, e estado da arte, para o caso do job shop com máquinas paralelas. / Shop scheduling is a combinatorial optimization type of problem in which we must allocate machines to jobs for specific periods time. A set of constraints defines which schedules are valid, and we must select one that minimizes or maximizes an objective function. In this work we use the makespan, which is the time the last job finishes. The literature contains several studies proposing techniques to solve shop problems such as the job shop and open shop. These problems allow the steps of the production processes to be either fully ordered or not ordered at all. With increasing complexity and size of industrial applications we find, more recently, several works which propose more general shop problems to model the production processes more accurately. The mixed shop, group shop and partial shop are examples of such problems In this work we propose an iterated tabu search for the partial shop, which is a general problem and includes several other more restrictive shop problems. The most important novel components of the solver are the initial solution generator, the neighbourhood, and the lower bound for the neighbourhood. In computational experiments we were able to show that the general partial shop solver is able to compete with, and sometimes surpass, the state-of-the-art solvers developed specifically for the partial, open, mixed and group shops. Sometimes a machine is a bottleneck in the production process, and is replicated. In the literature the parallel machines case has being included in several extensions of shop problems. In this thesis we also propose a technique to schedule the parallel machines heuristically, without including them explicitly in the representation of the problem. We use general techniques for the non-parallel machine cases to produce a fast tabu search heuristic results for the job shop with parallel machines.

The survey Distanshandeln idag 2005, made by the Swedish postal service, tells us that web shops started to pop up in the 1990´s and began competing with the catalogue sells in the end of the decade. Ten years ago, it was said that the web shops would take over the distance trade market. Today we know that did not happen. Internet shopping accounted for 4, 2 % of all distance shopping in Sweden last year. Our inquiry is guided by the observation that the catalogue is still in use and moreover, it seems to have changed very little from when we were kids. It might be that the catalogue has potentials that the Internet lacks. Hence, this study aims to identify and describe differences between mail-order catalogues and web shops in the presentation of fashion products. The theoretical frame of reference for this study consists of literature on marketing, brands, and fashion marketing by catalogue and Internet. This is primary an empirical study and the literature's function is that of inspiration and support for us in our analysis and our conclusions. The empirical material consists of a survey on the mail-order company Ellos’s spring and summer catalogue of 2009, and their web shop for the same time period. First we constructed a set of mutually exclusive criteria to apply in our analysis (e.g., colour, perspective and information). A number of standard garments were then chosen, and for each of these garments, we applied our model and performed a comparative analysis. To give the reader a better understanding of the survey's result, we included images to show specific phenomena along with our findings. The main differences between catalogues and web shops could be summarized as follows: Web shops provides immediate information about stock status and campaign prices, this cannot be done in the catalogue. The catalogues on their hand provides the customer with a lot of ideas on how to wear, and how to combine the different garments. This could easily be achieved in the web shop too, and we find it a bit surprising that it is not. / Program: Textilekonomutbildningen

Purpose: Can luxury fashion brands use websites and web-shops and still keep a sense of drama and exclusivity around their brand and at the same time avoid brand dilution?Background: The e-commerce opened up for new possibilities for the luxury fashion brands but due to the dotcom crash around the year of 2000 did many of them become reluctant to the Internet as a selling channel. LVMH was one of the first in this genre to start up a web- shop. It name was eluxury (eluxury.com), and sold products from LVMH’s brands like Louis Vuitton, Dior and Donna Karan. It started off in the US market and then spread to France and the United Kingdom. This inspired other brands like Gucci and Armani to also invest in e-commerce. Even though the success of these web-shops is there still an ongoing debate about whether or not luxury brands should adopt e-commerce. The major concern is the dilution of features like exclusivity and prestige of the brands, if they are present in this channel.Method: To meet the purpose a qualitative research approach was chosen. The qualitative data was collected through eight in-depth interviews with luxury fashion interested Swedish females. The answers from the interviews generated a picture of their online shopping habits, and the likes and dislikes of the websites and web-shops of Louis Vuitton, Burberry, Dior and Gucci. In addition it showed what makes a web-shop exclusive and well designed from a consumer/visitor point of view.Conclusion: The result of this research showed that it is good for luxury fashion brands to have distribution online because it makes the products a lot easier to get hold of for the consumers. Although there were several criteria that was needed to be fulfilled in order to design and create a well functioning and good web-shop. It was evident from the result of the study that the Internet can really be a good distribution channel, with only a little risk of brand dilution depending on how the web-shop is designed. To summarize, we say that a good website and web-shop meeting the criteria of the consumers can really create a stronger brand image and online sales, although a luxury fashion brand should also have good physical stores, a web-shop can in many ways really be a very suitable complement for marketing and distribution. / Program: Magisterutbildning i fashion management med inriktning modemarknadsföring

O desempenho dos sistemas de Planejamento e Controle de Produção e dos sistemas de Planejamento e Controle de Chão-de-Fábrica é fortemente dependente da qualidade e confiabilidade dos dados de operação e da rapidez com que estes dados são obtidos para análise e acompanhamento da execução dos planos de produção. O processo de coleta e tratamento destes dados tem sido pouco detalhado nos modelos de referência encontrados na literatura. Este trabalho posicionou a utilização de sistemas supervisórios para a coleta de dados de produção em sistemas de planejamento e controle no ambiente da manufatura discreta, propondo um roteiro de atividades a serem consideradas no desenvolvimento de sistemas de planejamento. / The Production Planning and Control Systems and Shop Floor Control Systems performance are extremely dependent of the quality and reliability of the operational data and readiness in data collection process, in order to provide information to analyse the execution of production plans. The data collection process has been pour detailed in the reference models found in literature. This work locates the supervisory and control data acquisition systems role in the landscape of discrete manufacturing planning systems and proposes a routing of tasks to be considered in developing process of a manufacturing planning system.

É perceptível a tendência contemporânea da multifuncionalidade do objeto e do espaço. Este último desdobra-se e desconstrói-se em ambientes inter ou não-relacionados, agregando funções num mesmo lugar. Se o espaço mais óbvio para se encontrar arte e história é em uma galeria ou em um museu, é de se estranhar que estabelecimentos comerciais possam atuar nesta função artístico-cultural. Neste caso, é quase imediato pensar que esta ação poderia ser exercida deficientemente ou que alguma forma de lucro estaria fortemente envolvida. Mas há exceções; são locais onde não só o objeto deve ser tocado, sentido, experienciado como nas instalações artísticas contemporâneas como o ingresso a eles é sempre livre. Como em galerias e museus, a exposição do objeto é primordial, podendo fazer parte de um cenário original e preservado, reconstituído ou quase teatral, onde esta recepção estética apoia-se também em um conjunto de informações e interações com seu espectador. Quando a arquitetura do lugar também destaca-se, especialmente se tombada pelo patrimônio histórico e artístico (ou com possibilidades de ser), torna-se quase impossível somente se ater a uma única atividade exercida no local e não ao conjunto em si. As relações e fusões entre estabelecimentos comerciais com alguns artifícios e técnicas museológicas, através de desdobramentos tais como loja-museu, loja de museu e loja-galeria são objetos desta pesquisa, onde procura-se não só refletir sobre a abrangência dos lugares culturais, como sobre a identidade de uma cidade através do comércio local. A opção por modos de pesquisa diversos textuais, iconográficos e de campo foi fundamental para a constatação do comércio como uma forma de cultura, sendo que os três estudos de caso, todos localizados na Cidade de São Paulo, possibilitam também verificar a necessidade de seleção para a explicação desta ocorrência, assim como a abrangência cultural através da descrição de práticas tanto em comum quanto bem diferentes entre si. Assim, o comércio associa-se à arte, ao design, à moda, à história, ao lugar e à identidade, constituindo-se também como uma demonstração a visões que negam ou excluem esta atividade como também sendo legitimamente cultural. / It is noticeable the contemporary tendency of the multifunctionality of an object and the space. The latter unfolds and deconstructs into inter or not related environments, aggregating functions in the same place. If the most obvious place to find art and history is in a gallery or in a museum, it is quite strange that commercial establishments are able to act in this artistic-cultural activity. In this case, it is almost immediate thinking about this action as one that could be defectively performed or that some kind of profit could be strongly involved. However, there are exceptions; they are places where not only the object must be touched, be felt, be experienced as in the contemporary installations art but also the ticket for them is always free. Like in galleries and museums, the exhibition of the object is primordial, being able to take part in a original and well preserved scenery, reconstructed or almost theatrical, where the aesthetic reception is also based upon a combination of information and interactions with the spectator. When the architecture of the place is remarkable too, especially if it is under governmental trust as a historic or artistic heritage (or it has great possibilities), considering only one performed activity in this spot is almost impossible when there is a combination of them. The relations and fusions among commercial establishments with some museological resources and techniques - by the expansions such as shop-museum, museum shop, shop-gallery, are objects of this research, which attempts not only reflecting about the scope of cultural places but also about the identity of a city, observing the local trade. The option for different ways of research textual, iconographic and of field was fundamental for the confirmation of the commerce as a form of culture, observing that the three case studies, all localized in the City of São Paulo, also enable to verify the necessity of selection for the explanation about this occurrence, as well as the description about the cultural scope of practices both in common and unlike each other. Thus, there are associations between commerce and art, design, fashion, history, place and identity, constituting oneself also as a demonstration to visions which deny or exclude this activity as a legitimately cultural one too.
