nÃo hà / Na conjuntura econÃmica atual, as organizaÃÃes, em busca de maior eficiÃncia e de vantagens competitivas sustentÃveis que lhes garantam crescimento no longo prazo, tÃm concentrado esforÃos em suas competÃncias principais, terceirizando as demais atividades da empresa, entre elas, as da logÃstica, o que levou ao surgimento e desenvolvimento do mercado de Operadores LogÃsticos (OLs). Esta dissertaÃÃo teve como objetivo principal caracterizar os OLs atuantes no Estado do Cearà em termos de identificaÃÃo e dimensionamento das empresas, das atividades logÃsticas realizadas e do desenvolvimento desse mercado. Para tanto, este trabalho assumiu uma natureza exploratÃria-descritiva, se utilizando do mÃtodo indutivo e do estudo de casos mÃltiplos, envolvendo a consulta de dados secundÃrios disponÃveis em periÃdicos e publicaÃÃes especializadas em logÃstica, bem como tambÃm a livros, dissertaÃÃes e teses jà produzidas, alÃm dos dados obtidos em visita aos sites das empresas objeto desta pesquisa. Como objetivo secundÃrio, o presente estudo buscou, atravÃs de pesquisa bibliogrÃfica, descrever e discutir os principais conceitos da logÃstica e sua importÃncia para a economia das empresas, caracterizar os OLs, enfatizando os principais conceitos e a evoluÃÃo dessas empresas no Brasil e avaliar alguns aspectos econÃmicos do mercado de OLs. Os resultados das anÃlises revelam um segmento formado por empresas relativamente jovens, em sua maioria de grande porte, mas que registram taxas positivas de crescimento, possivelmente decorrentes do grande nÃmero de serviÃos prestados, do uso intensivo da tecnologia e do fechamento de novos contratos, favorecido pelo crescimento das atividades nos diferentes setores econÃmicos do paÃs em 2010. Concluiu-se ainda, que os OLs prestam serviÃos aos mais variados tipos de indÃstria e que com polÃticas pÃblicas corroborando para minimizar problemas histÃricos no paÃs como a deficiÃncia de infraestrutura, carga tributÃria e trÃmites excessivamente burocrÃticos, poderia ser celebrado um expressivo crescimento econÃmico para o Estado do CearÃ. / In the current economic climate, organizations, seeking greater efficiency and sustainable competitive advantages that will ensure long-term growth, efforts have concentrated on its core competencies, outsourcing other business activities, including the logistics, which led to the emergence and development of markets for Logistics Operators (OLs). This work aimed to characterize the OLs active in the state of Ceara in terms of identifying and sizing of companies, logistic activities undertaken and the development of this market. Therefore, this study took an exploratory-descriptive, if using the inductive method and the study of multiple cases involving the consultation of secondary data available in journals and publications specializing in logistics, as well as well as books, dissertations and theses ever produced in addition to the data obtained to visit the websites of the companies object of this research. As a secondary objective, this study sought, through literature, describe and discuss the main concepts of logistics and its importance to the economy of enterprises, to characterize the OLs, emphasizing the key concepts and evolution of these companies in Brazil and assess some economic aspects OLs market. The analysis results show a segment comprised of relatively young companies, mostly large, but that record positive growth rates, possibly due to the large number of services, the intensive use of technology and the closing of new contracts, favored the growth of activities in different economic sectors in the country in 2010. It was also concluded that the OLS provide services to a range of industry and supporting public policies to minimize the historical problems in the country and the deficiency of infrastructure, taxes and overly bureaucratic procedures, could be entered into a significant economic growth for State of CearÃ.

A logistics centre, or control centre, is a major component for many industries, especially those that participate in activities related to transport vehicles and logistics, for instance, the mining industry. Previous research has shown that the capabilities of humans to process a large amount of information are limited. As the flow of information continues to increase in the future, Situation Awareness (SA) and task performance can decrease. Moreover, currently, an operator is dependent and restricted to their workstation to perform any necessary task, which is also a major hindrance that is being faced. This thesis project used Augmented Reality (AR) to tackle these problems and look at how the user experience of logistics operators working in these control centres could look like and improve in the next few decades. An augmented reality multimodal prototype was developed using a variety of technologies during this thesis project. The prototype was evaluated through both qualitative and quantitative methods. Six subject matter experts (SMEs) were selected as participants and completed a small quantitative survey, after which they were interviewed for more in-depth feedback. Results show a positive approval rating for the prototype, both in terms of usability and learnability. Additionally, a number of further solutions and possible applications emerged from interviews with the participants. Finally, it became apparent that one of the research sub-questions, about the overflow of information, could not be fully addressed by this prototype. However, possible solutions to that problem emerged from the project. / Ett logistikcenter eller kontrollcenter är en viktig komponent för många industrier, särskilt de som deltar i aktiviteter relaterade till transportfordon och logistik, till exempel gruvindustrin. Tidigare forskning har visat att människors förmåga att bearbeta en stor mängd information är begränsad. Eftersom informationsflödet fortsätter att öka i framtiden kan Situation Awareness (SA) och uppgiftsprestanda minska. Dessutom är en operatör för närvarande beroende och begränsad till sin arbetsstation för att utföra alla nödvändiga uppgifter, vilket också är ett stort hinder som står inför. Detta avhandlingsprojekt använde Augmented Reality (AR) för att ta itu med dessa problem och titta på hur användarupplevelsen för logistikoperatörer som arbetar i dessa kontrollcentra kan se ut och förbättras under de närmaste decennierna. En förstärkt verklighet multimodal prototyp utvecklades med hjälp av en mängd olika tekniker under detta avhandlingsprojekt. Prototypen utvärderades genom både kvalitativa och kvantitativa metoder. Sex ämnesexperter (SMF) valdes ut som deltagare och genomförde en liten kvantitativ undersökning, varefter de intervjuades för mer ingående feedback. Resultaten visar ett positivt godkännandebetyg för prototypen, både när det gäller användbarhet och lärbarhet. Dessutom framkom ett antal ytterligare lösningar och möjliga tillämpningar från intervjuer med deltagarna. Slutligen blev det uppenbart att en av forskningsundersökningarna, om överflöd av information, inte helt kunde behandlas av denna prototyp. Men möjliga lösningar på det problemet framkom ur projektet.
