The thesis that follows is performed in collaboration with Nitator in Oskarström.The factory in Oskarström focuses on laser cutting, robotic welding and surfacetreatment of steel for the automotive industry.The project aims to streamline the flow of materials in production by automatingthe movements of the forklifts, running to and from the interlayer, and betweenworkstations.The project started with a systematic literature search. The literature searchshowed the research position around the AGV-system. Also a review of studentliterature was made, so that a suitable method for practical implementation couldbe developed and applied. Selected method uses both quantitative and qualitativeapproaches, which is analyzed by using triangulation.The work has resulted in a modified layout of the current facility in Oskarströmthat can be used for the implementation of the AGV-system. It has also resulted inthe tender documents and profitability calculation from several of AGV-suppliers..

Government regulations and customs duties restrict the import of trucks to some of the markets to which Scania tries to sell their trucks. The distribution problem due to these regulations is solved by the foreign assembly department, KD, at Scania. This means that competence is needed and costs are added not related to Scania's core operations.The aim of this master thesis has been to analyse and to evaluate alternative ways of managing the packing operations considering cost, quality and work organisation. To study and examine the work methods and operations of today and also to present methods measuring the operations effectiveness and productivity.We have used the system approach to maintain totality and to understand the component's relation to this totality. Field studies combined with studies of relevant literature and studies of other companies operations have given us the knowledge and the understanding of the packing operations needed.

Ericsson?s factory in Kumla, Modules Kumla, became a hub for radio modules and micro base stations, which enables mobile communication through radio base stations, in 2004. Because of this the factory focuses more on the logistics operations. This has led to a need to be able to plan the capacity for the materials handling system. This master thesis has therefore been performed at Modules Kumla to develop a capacity calculation model for the material handling flow during the autumn of 2005.The work has contained a mapping of the material handling flow regarding to which activities was performed and how much time they consumed.

Syftet med denna studie är att undersöka hur elever i en vanlig svensk mellanstadieklassupplever flow i sitt lärande och vilka faktorer som påverkar upplevelsen av flow.För studien valdes en kvalitativ metod i form av enskilda intervjuer. Tre pojkar och treflickor i en klass 4 på mellanstadiet fick berätta vilket deras favoritämne var, och sedanbesvara frågor om hur de upplevde sitt favoritämne och hur de upplevde de övrigaämnena. Frågorna var skapade utifrån de olika faktorerna som påverkar flow enligtMihaly Csíkszentmihályis flowteori (Csíkszentmihályi, 1993).Resultatet av min undersökning visar att eleverna som intervjuades upplever flow iskolan, och då mest i favoritämnet. Det finns även exempel på motsatsen där entusiasmoch flow saknats i skolarbetet. Faktorer som har betydelse för att flow ska uppkomma ärbland annat rätt svårighetsgrad på uppgiften så att utmaningen anpassas efter individen,rätt tid och arbetstakt för genomförandet av uppgiften, möjlighet till medbestämmandeoch inflytande för den som utför uppgiften samt eliminerandet av störmoment underarbetet med uppgiften.Undersökningens resultat visar att flow har betydelse för elevens motivation och iförlängningen sannolikt också för elevens lärande.

A district heating plant has the advantage that it can take advantage of the waste heat from industries and use of cheap fuels to produce heat. But for the long term is competitive requires that energy is also saved in district heating plants. One way to save energy in a district heating system is to increasing cooling to the return temperature. This leads to less power needed to drive the distribution pumps,  and that more energy could be extracted from the same amount of fuel by an improved flue gas condensation.In Karlskoga the return temperature into the district heating plant is high. They would therefore reduce the return temperature in order to extract more energy from the flue gases.

Syftet med denna studie har varit att undersöka relevansen i tre olika teorier som förklarar hur Flow kan upplevas på en arbetsplats. Teorierna är skapade efter forskning från Csikzentmihaly, Hofstede samt Maslow. Undersökningen har skett på två olika arbetsplatser inom två olika yrkesgrenar för att finna om eventuella skillnader mellan dessa två arbetskontext kan påverka upplevelsen av Flow. Det ena företaget kategoriseras som en affärsmiljö och det andra företaget rubriceras som en kontorsmiljö. Tre hypoteser skapades som var för sig testade de tre teoriernas effekt på Flow.

This is a report written for an examination project C-level, on the subject of energy. The examination project is a product of the FVB Sweden AB (district heating bureau). It started with a meeting with Stefan Jonsson FVB Sweden AB, were he explained the content of the project, and from this a presentation of the problem was made. The problem that needed to be solved was how they could control the valves in the system to provide heating to everyone in the system. The valves are often oversized so the pump in the heating plant would have to be enormous to be able to provide enough flow to be sufficient, if everyone in the system had there valves fully opened. I came up with two solutions to the problem, one was a wireless network that could keep track of the valves and the other solution was an extra sensor that was placed on the radiator.

Detta arbete har utförts för att undersöka frågeställningen ?Hur bör ett dataspels tutorial designas för att spelaren ska lära sig samtidigt som den främjar uppkomsten av flow??. För att besvara detta har teorier inom pedagogik, lärande av spel, användbarhet och flow samt mer generella teorier kring spel studerats för att skapa en teoribildning inom området. För att testa detta har ett spel med två olika tutorials skapats. Detta spel har sedan använts för att, med hjälp av två testgrupper, samla data om hur spelare lär sig samt deras flowupplevelse.

The purpose of this study is to increase the understanding of activities, flows and waste in a company's production process. By performing a value stream analysis, non-value adding activities are identified in a production process and then the suggested improvements that can reduce lead times will be stated. The value-stream mapping identifies the flow of information and the flow of material in a production process and this provides the basis for the identification of non-value adding activities.We conducted the study at Lammhults Möbel AB in Lammhult Sweden, where the production flow of Spira-21 has been investigated. This to identify any non-value adding activities that affect the flow negative and consumes time and money in a non-value adding way.A reasonable approach for the project was taken by studying the methodologies and theories. We conducted interviews and site surveys at Lammhults Möbel AB where the flow of information and material in the production process were investigated.

Detta arbete syftar till att undersöka hur Csikszentmihalyis teorier kring optimala upplevelser, eller flow-upplevelser, kan appliceras på praktisk speldesign. I arbetet kombineras Csikszentmihalyis definition av begreppet flow med Jenova Chens riktlinjer för flow-uppmuntrande design i singleplayerspel för att ge underlag för framtagandet av ett brädspel i vilket applicerbarheten hos deras teorier och riktlinjer på multiplayerspel undersökts. För att teorierna och riktlinjerna effektivt skulle kunna undersökas utvecklades det tre olika versioner av brädspelet som alla innehåller olika element som, enligt Csikszentmihaly och Chen, bör alstra flow. Ett flertal spelgrupper fick spela dessa tre versioner och via enkätundersökningar och intervjuer förmedla hur de upplevde de olika versionerna, både som individuella produkter och i jämförelse med varandra. De data som erhålldes från dessa undersökningar indikerade på att nivån av kontroll spelaren har över sin spelsituation spelar en väldigt avgörande roll i hur han eller hon upplever spelaktiviteten i sin helhet..

This report describes work on the thesis ?IT systems and organizational development?. The work is carried out on Stocksbro Energi AB, during spring 2009. The company wanted better flow in their production but also review if the inventory management function located in Visma SPCS Administration 2000, could be used in the organization. Under the first part of this report the system were tested to ensure if the system would work together with the organization.

Human Computer Interaction (HCI) handlar om att utveckla produkter med god användbarhet. Med användbarhet menas att system ska vara lätta att använda och lära. Jakob Nielsen är en av förgrundsfigurerna när det gäller riktlinjer för hur detta ska uppnås. Han har utvecklat tio kriterier som kan användas för att ett så bra system som möjligt ska kunna utvecklas.På senare år har forskare börjat se till, inte bara tekniska aspekter utan även till de känslor som användaren kan tänkas uppleva under det att denna interagerar med en webbsida. Ett flertal forskare har utvecklat teorier kring begreppet Flow.

The Swedish armed forces are facing a change, a change in both organization and profession. From a conscript military service system, the Swedish Armed Forces has changed to having full-time contracted soldiers. Conscript military service has a history of over a hundred years; it was introduced in 1901 and has survived two world wars and the Cold War.The Swedish armed forces have changed to have contracted soldiers. My reflection is whether the armed forces really have had time for this changes that the new professionalization has meant. Today the Swedish armed forces consists of contracted soldiers, soldiers who are employed full time and costs the armed forces a lot of money.

The aim of this report is to analyse the logistics of a medium sized restaurant and give an overall solution for improvements on the restaurant's logistics. The restaurant of interest belongs to Laponia Hotel and is located in Arvidsjaur, Sweden. Investments for over 100.000 Euros are planned for the hotel, which includes a reconstruction of the restaurant. The details on how the restaurant will be reconstructed are not yet known. I therefore chose to analyse the problemin general terms and find a solution that is focused on the logistic system itself rather than its layout.

This thesis has been done at the powder department (GH) at AB Sandvik Coromant in Gimo. With a rheometer measurements has been made on raw materials and powder blends. The focus of this report has been to find correlations between raw material powders and press data, comparisons have also been made between raw materials and powder blends.The rheometer can show information of how a powder act in flow conditions, together with air and with pressure. Analyses has been done comparing the rheometer data with press parameters (for example: rejected orders, weight variations and the compaction pressure) with the goal to find correlations between the powders flow properties and the powders compaction in production.The measurements and analyses have been showing that the powder flow properties depends on the powders composition and that properties like flow rate, aeration and permeability varies between powder blends and batches of the same powder sort. It seems to exist a correlation between the pressure force and the flow rate of a raw material.
