    Measuring efficiency in a container port terminal - A method for performing OEE-measurements

    No full text
    Denna studie har genomförts på APM Terminals i Göteborg. APM Terminals bedriver en containerhamnsverksamhet vilket ställer höga krav på effektiv utrustning och processer. Detta då fartygens tidsscheman är hårt pressade och hantering av containrarna måste ske inom avtalad tidsram. För att kunna utveckla verksamheten och uppnå högre effektivitet på teknisk utrustning krävs en gedigen driftsuppföljning för att identifiera störningar och stopp i produktionen. För att mäta utrustningseffektiviteten använder APM Terminals verktyget OEE (Overall Equipment Effectiveness). OEE är ett tal som beror på utrustningens tillgänglighet, effektivitet och kvaliteten på produkterna. Studiens syfte var att undersöka APM Terminals nuvarande metod för OEE-mätningar, för att sedan försöka förbättra metoden med avseende på användarvänlighet, skalbarhet och tidsåtgång. Ett teoretiskt ramverk med avseende på OEE har tagits fram genom litteraturstudier. En grundlig beskrivning av nuläget har tagits fram genom empirisk undersökning som innehöll dokumentinsamling, intervjuer och observationer. Genom jämförelse av det teoretiska ramverket och nulägesbeskrivningen har de problem som finns med APM Terminals nuvarande metod analyserats. Utifrån denna analys har förbättringsförslag arbetats fram. Det fanns flertalet problem med APM Terminals nuvarande metod. De flesta av dessa problem kan relateras till antalet mätkoder APM Terminals använde i sin metod. Studien presenterar rekommendationer för att minska antalet mätkoder. Detta leder även till en förbättring av analysmöjligheterna då ett mindre antal mätkoder leder till möjligheterna att göra analysen snabbare. Andra exempel på rekommendationer är att APM Terminals bör undersöka om OEE är rätt arbetssätt att använda i en containerhamnsmiljö

    How autonomous cars can affect the car industry - Implications for user experience and competition

    No full text
    Autonomous cars have not only been identified as having the potential to change the car industry but also to have a high impact on society in general. Relieving people from driving the car will enable passengers to perform other activities during the ride, which in turn can create opportunities for shaping the user experience. The autonomous technology together with other emerging trends in the transportation industry can also come to change the competitive landscape of the car industry. One such important trend is the expected shift to shared ownership models. This study aims to investigate the user experience in future autonomous cars as well as how autonomous cars can affect the competitive landscape of the car industry. In order to reach conclusions within this subject, a combination of empirical findings and previous literature have been examined and discussed. The empirical part of this study is based on a qualitative method where the participants get to create collages to express their needs and wants in future autonomous cars. This study shows that people want to perform most activities within the categories relaxation, entertainment, and socialization. The result indicates that the activities people want to perform within these categories are similar, while the channels used to consume digital content varies. The study discusses the opportunities for a digital platform to enable the users to engage in a customized user experience adjusted to their specific wants. Furthermore, this study finds that there might be a difference in what people value regarding the aspects of an owned car compared to a shared one. This paper also indicates that the competitive landscape of the car industry can come to change when cars are autonomous and shared. When the industry boundaries expand to include new types of players, the drivers for competition change and new key success factors become evident. While traditional drivers for competition might stay important for car manufacturers, this study has identified new key success factors that will be of high importance for firms providing a shared mobility service. For these players, a critical mass of cars, an installed base of users and networks effects become important factors for obtaining a competitive advantage
