Examensarbetet utfördes hösten 2020 på Scania Industrial Maintenance i Södertälje. Arbetet har fokuserat på två avdelningar inom produktionsavsnitten Transmissionsbearbetning samt Motorbearbetning, en avdelning från vardera produktionsavsnitten. På Transmissionsbearbetning undersöktes avdelningen Hårda kugg och på motoravdelningen undersöktes DMAHB. Huvudmålet för examensarbetet är att så långt som möjligt definiera teknisk tillgänglighet för Scania baserat på produktions- och underhållsdata. Med hjälp av underhållsingenjörer, underhållstekniker samt tidigare erfarenheter från arbete på Scania har information- och processkännedom införskaffats via besök och intervjuer. Data från respektive linje har analyserats och litteraturstudier har gjorts för att få en djupgående förståelse för problemet. Nuläget inom produktion och underhåll har givit en helhetsbild över problematiken med att definiera teknisk tillgänglighet. Flertalet faktorer har tagits i åtanke såsom kultur, bristande resurser, nyckeltal och standarder. Mätning av teknisk tillgänglighet kan göras på flera sätt enligt svenska underhåll standarder vilket tas upp i arbetet. Det som i det här arbetet anses passa Scania är att utgå ifrån drifttiden och tid för återställning för att få fram underhållets påverkan på produktionen. För att uppnå det här behöver Scania börja mäta drifttiden för varje maskin och förbättra rapporteringen av stopptiderna. / The examination project was carried out in the autumn of 2020 at Scania IndustrialMaintenance in Södertälje. The work has focused on two departments within the production sections Transmission processing and Engine processing, one department from each production section. In the Transmission processing, the Hard Gear section was examined, and in the engine-section was DMAHB examined. The main goal of the examination project is to define technical availability for Scania as far as possible based on production and maintenance data. With the help of maintenance engineers, maintenance technicians and previous experience from working at Scania, information and process knowledge has been acquired through visits and interviews. Data from each line have been analyzed and literature studies have been done to gain an in-depth understanding of the problem. The current situation in production and maintenance has provided an overall picture of the problems with defining technical availability. Most factors have been considered such as culture, lack of resources, key-figures, and standards. Measurement of technical availability can be done in several ways according to Swedish maintenance standards, which is addressed in the work. What in this work is considered suitable for Scania is to start from the operating time and time for restoration to obtain the impact of maintenance on production. To achieve this, Scania needs to start measuring the operating time of each machine and improve the reporting of downtime.

El presente estudio tuvo como objetivo incrementar el nivel de servicio en la empresa S&E INOXI S. A. C., la cual se dedica a fabricación y venta de muebles en acero inoxidable y brindar servicios de mantenimiento, ya que se encontraba en un escenario de pérdidas económicas equivalente a S/.28 470,00, debido a la penalización del 5% por incumplimiento de la fecha de entrega. Asimismo, existían pérdidas por materia prima de S/. 96 905,03. El presente trabajo propone una mejora del sistema productivo mediante la implementación de las herramientas de Lean Manufacturing para incrementar su nivel de servicio. Esto se logró mediante la ejecución de un diagnóstico de la situación actual del proceso de fabricación de trampa de sólidos y grasas, evaluación y determinación de los métodos y/o herramientas de ingeniería, seguidamente se elaboraron propuestas de mejora del proceso que contribuyeran a incrementar el nivel de servicio y finalmente se realizó el análisis costobeneficio del proyecto. Como resultado de la investigación se obtuvo un incremento del 23,1% en el nivel de servicio, se redujo la pérdida de materia prima en un 84,13%, esto mediante el incremento del 23,51% de la eficiencia física y se logró una disminución del 51,87% de la distancia recorrida. Además, se redujo el cuello de botella en un 10,64% y el tiempo de flujo del proceso en un 9,88%. También mediante las capacitaciones y el diagrama OT se consiguió la polivalencia del operario, consiguiendo la reducción de un 67,41% del tiempo ocioso para un lote de 3 unidades. / The objective of this study was to increase the level of service in the company S & E INOXI S. A. C., which is dedicated to manufacturing and selling stainless steel furniture and provide maintenance services, since it was in a scenario of economic losses equivalent to S/. 28 470,00, due to the penalty of 5% for breach of the delivery date. Likewise, there were losses by raw material of S/. 96 905,03. The present work proposes an improvement of the productive system through the implementation of Lean Manufacturing tools to increase its level of service. This was achieved through the execution of a diagnosis of the current situation of the manufacturing process of solids and grease traps, evaluation and determination of the methods and / or engineering tools, followed by proposals for improvement of the process that would contribute to increase the level of service and finally the cost-benefit analysis of the project was carried out.

In addition, the bottleneck was reduced by 10,64% and the process flow time by 9,88%. Also through the trainings and the OT diagram, the polyvalence of the operator was achieved, achieving a reduction of 67,41% of idle time for a batch of 3 units.

Many industries are moving to adapt to the competitive market and customer requirements to increase productivity, flexibility of their production systems, and achieve optimal improvement. This made the simulation attract attention by enabling its users to test several scenarios with different options and concepts before applying them on the ground. The purpose of this thesis is to test the role of simulation in making decisions about the optimal layout design within the available cost and to present a concept for simulating the production system after redesigning the smart factory, which includes the number of machines, tiles and movers as an assumption and the demand for products with a variable dynamic flow. The simulation model addresses the concept of the production process by implementing modern technologies with their effective characteristics to ensure a smooth flow of products between all the machines that present as components of the smart factory. The developed optimal model includes the components of the smart factory in addition to all the requirements that must be considered to ensure increased flexibility and efficiency of the production system. In addition, the optimal design with the lowest cost and the concept of the production process were presented through the results obtained regarding productivity and performance. This thesis presents the challenges might be arise when employing the simulation as a tool to redesign and suggestions mechanisms to reduce them in the discussion chapter. The design model presented in this thesis serves as a connecting point for continuing future initiatives and developing the production concept.

Sveriges livsmedelssystem står inför stora utmaningar såsom negativ miljöpåverkan och beroendet av att importera både livsmedel och insatsvaror. Livsmedelsproduktionen, som idag domineras av det konventionella jordbruket, har bland annat inneburit utarmade jordar och exploaterade resurser samt utsläpp av gifter. Studien syftar till att sammanställa och jämföra den vetenskapliga forskningen och samhällsdebatten angående alternativ livsmedels-produktion. Studien är avgränsad till att redogöra för produktionssystemen regenerativa jordbruk och akvaponiska system. Den vetenskapliga forskningen angående regenerativa jordbruk och akvaponiska system sammanställdes i ett kunskapsläge. En kvalitativ innehållsanalys utfördes för att identifiera och sammanställa samhällsdebatten kring systemen. Samhällsdebatten rörande de två alternativa livsmedelsproduktionssystemen bildade följande teman: den samordnande rösten, den offentliga rösten, forskarens röst, den operativa rösten, samt den övriga rösten. Inom dessa teman identifierades följande sex kodord: livsmedelsförsörjning, miljömässiga aspekter, ekonomiska aspekter, sociala aspekter, utmaningar samt möjligheter. I vår undersökning har vi inte formulerat några nya begrepp, däremot har vi funnit samband såväl som avvikelser och glapp mellan samhällsdebatten och den vetenskapliga forskningen. / Sweden's food system faces major challenges such as negative environmental impact and is dependent on importing both food and intermediate goods. Food production, which today is dominated by conventional agriculture, has meant, among other things, depleted soils and exploited resources as well as emissions of toxins. This study aims to compile and compare the scientific research and the public debate regarding alternative food production systems. The study is limited to account for the production systems regenerative agriculture and aquaponic systems. The scientific research regarding regenerative agriculture and aquaponic systems was compiled in a state of knowledge. A qualitative content analysis was performed to identify and compile the public debate about the systems. The public debate concerning alternative food production systems formed the following themes: the coordinating voice, the public voice, the researcher's voice, the operational voice, and the miscellaneous voice. Within these themes, the following six code words were identified: food supply, environmental aspects, economic aspects, social aspects, challenges and opportunities. In our study, we have not formulated any new concepts, however, we have found connections as well as discrepancies and gaps between the public debate and the scientific research.

The global market is very competitive due to fast changes in complex business environments and to survive or expand the business, organizations must embrace organizational change. However, adapting to change is not always easy, where organizations may experience obstacles and resistance along the way. Organizations may also experience that it is very hard to implement lean successfully, due to lack of know-how but especially resistance. The traditional way is to blame the blue-collars for the disturbing circumstances but in modern times the wind has changed its course where the managers themselves can be a contributor for implementation failures. Therefore, the aim of the research is to investigate what advantages that can be obtained by implementing a certain change initiative. Furthermore, to determine where resistance occurs and how to eliminate or reduce them. The change initiative in this research is implemented by conducting a case study in a Small Medium Enterprise (SMEs), where the main goal is to reduce the changeover time of a machine, by finding improvement suggestions using the Single Minute Exchange of Die (SMED) methodology. The results generated several improvement opportunities and gave an indication that there is a huge potential for improvements and elimination of waste during a typical changeover. The positive outcomes of implementing these improvement opportunities could theoretically reduce the changeover time, which directly reduces the overall cost but higher responsiveness, flexibility and efficiency can also be obtained. However, the evidence tells a story where the organization could experience obstacles during the implementation of the improvement suggestions, due to several factors. Surprisingly, the evidence points out that one root problem for resistance is difficulties of describing the underlying reason of the change initiative to the blue-collars. Moreover, there is in fact resistance and lack of awareness of the SMED methodology among the blue-collars and the managers, where fear of the unknown is another root problem for resistance.

The industry is facing major challenges today. The challenges are tougher global competition, customers who require individualized products and shorter product lifecycles. The predicted industrial revolution is a way to deal with these challenges. Industry 4.0 includes strategies linked to several technologies that will meet the new needs. Smart factory is a central concept in industry 4.0, which involves connected technologies of various kinds. Such as digital manufacturing technology, network communication technology, computer technology, automation technology and several other areas. In this work, these were defined as smart factory technologies. Implementing such technologies will result in improved flexibility, resource productivity and efficiency, quality, etc. But, implementing smart factory technologies poses major challenges for the companies. Laboratory environments can be utilized to address the challenges. This results in a new problem, how to transfer a smart factory technology developed in a laboratory environment to a full-scale production system. In the literature study no, structured approach was identified to handle this challenge. Therefore, the purpose of this work was to: create a work process that supports the technology transfer from a smart factory compliant laboratory environment to a full-scale production system. To justify the purpose, the following research questions were answered: RQ1: What are the differences in the operating environment between the laboratory and the full-scale production system? RQ2: How is a smart factory technology determined ready to be implemented into a full-scale production system? RQ3: What critical factors should a work process for the implementation of smart factory technologies include? The research questions were answered by conducting a multiple-case study in collaboration with Scania CV AB. During the case studies, interviews, observations and other relevant types of data collection were conducted. The results were as follows: RQ1: How difficult it is to transfer a technology from a laboratory environment to a full-scale production system depends on how large the differences between these are. The general difference is that laboratory environments are used to experiment and develop technologies and a full-scale production system is used to produce products. Some want the laboratory environment to be an exact copy of a full-scale production system, but this is not appropriate because it means you lose the freedom of experimentation and it would be much more expensive. RQ2: Determining whether a smart factory technology is ready consists of two parts, laboratory activities and pilot testing. A structured assessment method has been developed. The laboratory operations reduce the risks and contribute to raising the degree of maturity of the technology. In pilot testing, it is important not to interfere with the full-scale production system stability. This is the reason for doing pilot testing in a delimited area first and checking that the technology works as desired. RQ3: The critical factors identified were: competence and knowledge, technology contributing to improvements, considering risks with implementation, cost versus potential improvement, clear goals and reason for implementation and communication.

A agricultura desempenha, desde a colonização do Vale do Ribeira-SP, papel central nas transformações e no desenvolvimento desta região, constituindo-se em locus de investigação e entendimento de suas características marcantes: a pobreza e a conservação do ambiente natural de Mata Atlântica. Através da construção da história agrária do município de Iguape - pontuada por eventos históricos de importância regional - buscamos averiguar como o desenvolvimento da atividade agrícola conjugou o uso da natureza e a satisfação das necessidades humanas desde a virada do século XIX para o XX - quando se configurou uma organização rural tipicamente cabocla - até os dias atuais. Para construir uma história agrária valemo-nos do conceito de sistema de produção agrícola, tendo por referência central o regime de uso do solo, tal como definido por Boserup (1983). Nesta pesquisa, submetemos à análise os processos sociais decorrentes da evolução agrária, a partir de seus aspectos materiais e objetivos e daqueles simbólicos e subjetivos inerentes às práticas sociais. A organização cabocla esteve estreitamente ligada à agricultura tradicional de base tecnológica itinerante, cuja prática exige a ocorrência e o uso da mata, para fins de exploração da efêmera fertilidade do solo. A partir da década de 1960, uma série de eventos associados à incorporação econômica regional - como as migrações, especulação imobiliária, incentivos à modernização produtiva - iniciaram processo de desorganização do sistema de agricultura caboclo e das relações e dinâmicas sócio-culturais implicadas. Já no final da década de 80, julgamos terem sido as novas regras de exploração da Mata Atlântica, estabelecidas pela Legislação Ambiental, determinantes para a conversão da base técnica itinerante, ao impor expressiva restrição às áreas cultiváveis e proibir a derrubada da vegetação florestal. Procuramos demonstrar como este processo foi acentuado pela nova orientação política que alterou a forma e a presença do Estado na região. Através de pesquisa de campo avaliamos como a população rural de tradição cabocla reorganizou a técnica agrícola, as relações de produção e sua articulação com o mercado. Dentre outros efeitos, observamos a formação de produtores desagregados socialmente, desenraizados de sua cultura e empobrecidos economicamente. / Agriculture as undertaken in the Vale do Ribeira, Sao Paulo region from colonization time, has been a key element in the area\'s development and transformation, a real object of study and investigation to further understand its marked traits: poverty and the Mata Atlântica environmental safekeeping. Via the build up of the Iguape district agricultural history - rich in important regional historical events - we strived to deepen knowledge of agricultural development in how nature was used and also the means for fulfilling human needs from the turn of century XIX to XX - when a typically caboclo organization was identified - to present days. To further build up an agricultural history, we have made usage of the \"agricultural production system\" concept, as reference the soil usage regime, as defined by Boserup (1983). In this survey we submit to analysis the social processes resulting from agricultural evolution, starting from material aspects, goals, symbols and subjective values pertaining to social action and mutually determined by economics. The caboclo organization was deeply linked to traditional farming rooted in shifting technology, which banked on the existence and usage of woods, its fleeting fertility and land rotation. From the 1960 decade on, a series of events associated to regional economic incorporation - such as migrations, real estate dealings, modernization output subsidies - led to the process of disorganization of the caboclo agricultural system and of implied dynamic socio-cultural relations. In the late 80\'s, we believe that the new Mata Atlântica ruling, set down by the Environmental Legislation, determining the itinerant technique conversion, while setting significant restriction to arable areas and the banning of forest clearing. We show how this process was further determining under the new political orientation which altered the presence and form of the State in the region. By means of field work we studied how the caboclo tradition bred rural population reorganized agricultural techniques, production schemes and market handling. To mention among other effects, we found socially disrupted producers, culturally uprooted and economically impoverished producers.

No. of bitstreams: 1 Michel Jorge Samaha.pdf: 2335647 bytes, checksum: 7af3f5eab3158ad2008664ed705c7072 (MD5) Previous issue date: 2017-03-07 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Based on the welfare system approaches (WS) and variety of capitalism (VoC) designed by Gösta Esping-Andersen and Peter Hall and David Soskice, respectively, this thesis focuses on the growing theoretical concern with the possible complementarities between the social protection system and the capitalist production system. When these approaches are articulated it is assumed that Brazil has a variety of combinations of these systems and cannot be typified as a homogeneous case. As Brazilian reality is heterogeneous, unequal and complex, the territorial scale chosen for the research were the Federative Units. The objectives of the thesis are to characterize the welfare systems and the varieties of capitalism in the Brazilian States, test the determination among them and identify the factors and the complementarities capable of explaining their economic heterogeneity and social protection. In addition to these goals, the study aims to show that the States are heterogeneous both in characterization of VoC as well as in terms of their WS; the States with matching systems present a significant complementarity and are nearby states. Despite the thesis limitations, it provides a theoretical framework for studying the internal variability of the types of welfare systems and varieties of capitalism, contributing to the construction of a typology adapted to the Brazilian heterogeneity. Furthermore, an ethnic dimension was introduced in the composition of the state types found, a theme that has been overlooked by the specialized literature. / A crescente preocupação teórica com as possíveis complementariedades entre o sistema de proteção social e o sistema de produção capitalista é desenvolvida nesta tese, tomando-se como referências as abordagens dos Regimes de Bem-Estar (RB) e de Variedade de Capitalismo (VoC), concebidas respectivamente por Gösta Esping-Andersen e Peter Hall e David Soskice. Ao integrar essas abordagens, assume-se o pressuposto de que o Brasil abriga uma variedade de combinações desses sistemas, não podendo ser tipificado como um caso homogêneo. A realidade brasileira é heterogênea, desigual e complexa, por isso a escala territorial eleita para a pesquisa foi a das Unidades Federativas. Os objetivos da tese consistem em caracterizar os regimes de bem-estar e a variedades de capitalismo nos estados brasileiros e testar a determinação entre eles, e, ainda, identificar os fatores e as complementariedades capazes de explicar a heterogeneidade econômica e de proteção social dos mesmos. Além de perseguir esses objetivos, o trabalho pretende mostrar que as unidades federativas são heterogêneas tanto na caracterização da VoC como no seu RB, e que estados com regimes coincidentes apresentam uma significativa complementariedade e estão espacialmente próximos. Não obstante suas limitações, a tese oferece um referencial teórico para estudar a variabilidade interna dos regimes de bem-estar e variedades de capitalismo, contribuindo para a construção de uma tipologia adaptada à heterogeneidade do Brasil. Além disso, foi introduzida uma dimensão étnica na composição dos tipos estaduais encontrados, tema quase negligenciado pela literatura especializada.

O presente trabalho levanta questões sobre algumas formas particulares de estruturação de um sistema profissional de produção cultural para as artes plásticas no eixo Rio de Janeiro São Paulo no período que coincide com um momento de florescimento político e econômico e se fortalece a partir da segunda metade dos anos 1940 e ao longo das décadas de 1950/1960. No que concerne especialmente aos museus de arte moderna, observou-se um fortalecimento institucional em torno do qual o sistema artístico brasileiro se estruturou. Para se chegar a essa conclusão foram analisados os aspectos estruturais (econômicos e políticos) centrados no eixo Rio de Janeiro São Paulo, e conjunturais, a partir das particularidades do fenômeno da arte da vanguarda construtiva brasileira. Foram consideradas as visões dos artistas nacionais em relação tanto à questão da arte de vanguarda como na sua relação com o museu. Consideramos, também, a Bienal como instituição, seu vínculo com os artistas e com o próprio MAM/SP no processo de divulgação da arte. Avaliamos a ação artística, peculiar pela presença das vanguardas construtivas, que envolvia grande participação dos artistas no cotidiano museológico. Além disso, consideramos o estreito diálogo que havia com os críticos que atuavam em veículos de comunicação. Como parte fundamental do estabelecimento de um sistema profissional de produção cultural, avaliamos a consolidação de um mercado de arte com base na atuação de marchands e na criação de galerias privadas em uma ação ainda não muito distinta daquela dos museus. Os movimentos concreto e neoconcreto, na medida em que se caracterizam como vanguardas artísticas e sua atuação permitiu a mobilização do suposto sistema em torno das discussões sobre suas novas propostas éticas e estéticas, foram considerados pontualmente. / This thesis raises issues on some specific ways of structuring a professional system of cultural production for the arts in the circuit Rio de Janeiro São Paulo coincident to a moment of political and economical emergence that gets stronger from the middle of the 1940s and during the 1950/1960 decades. Regarding in special the museums of modern art, it was observed an institutional strengthening around which the Brazilian artistic system was structured. To reach that conclusion structural aspects the economics and politics in the circuit Rio de Janeiro São Paulo as well as situational ones were considered on the specificities of the phenomenon of the Brazilian constructive vanguard art. We also considered the vision of the national artists on the art of vanguard and its relation to the museum. Also, we considered the Bienal and its relation with the artists and with the Museum of Modern Art of São Paulo itself in the process of divulging the art. We evaluate the artistic action, peculiar because of the presence of the constructive vanguards, and that involved a great participation of the artists on the museum day-to-day. Besides that we consider as well the close dialogue with the critics who worked on the vehicles of mass communication. As a fundamental part of the establishing of a professional system of cultural production, we evaluate the consolidation of an art market based on the activities of the dealers and the creation of private galleries in one action not yet very much distinct from that of the museums. The concrete and neoconcrete movements were specially considered because as artistic vanguard, their performances enabled the mobilization of the supposed system around the discussions on its new ethical and aesthetic proposals.
