Volvo Aero utvecklar, konstruerar, tillverkar och utför underhåll av motorer och tillhörande komponenter för civila och militära flygplan. Visionen är att leverera världsledande transportlösningar genom ständig förbättring och långsiktig utveckling av verksamheten, vilket för det dagliga arbetet innebär systematisk problemlösning genom metodiken praktisk problemlösning, vars ursprung är Toyota.Syftet med studien var att undersöka huruvida Volvo Aeros tillämpning av praktisk problemlösning var enkel, systematisk och vägledande, vilket ur Toyotas perspektiv ger förutsättning för effektiv problemlösning.Inledningsvis beskrevs Toyotas inställning och beteende till problemlösning utifrån The Toyota Way, som sedan följdes upp med en litteraturstudie gällande praktisk problemlösning. Vidare genomfördes en pilotstudie där Volvo Aeros tillämpning av praktisk problemlösning applicerades på ett organisatoriskt problem. Därefter utvärderades pilotstudien och förbättringsområden identifierades där metodiken var svår, otydlig och otillräckligt vägledande. Slutligen föreslogs följande förbättringar gällande Volvo Aeros tillämpning av praktisk problemlösning, vilka var vetenskapligt förankrade till Toyota.Definiering och analysering av symtomen ger förståelse för problemets orsaker.Kvantifiering av nuvarande tillstånd och det förväntades åskådliggör problemets omfattning.Framgår grundorsaken tydligt är sannolikt motåtgärden uppenbar.En god tillämpning av Plan-Do-Check-Act (PDCA) utgör ett effektivt och kraftfullt maskineri för ständig förbättring.Förbättringarna som föreslogs syftade till att förenkla Volvo Aeros metodik och ge användaren ökad trygghet och vägledning, vilket ger förutsättning för effektiv problemlösning som möjliggör daglig tillämpning och främjar ständig förbättring. .

Bakgrund: Intresset för processer och framförallt utveckling eller förbättring av processer har på senare år ökat. Detta kan ha sin grund i att många företag har behållit föråldrade rutiner och processteg samtidigt som verksamheten utvecklats, något som resulterat i onödigt komplexa processer som påverkat företags ekonomiska och praktiska prestationer. En annan orsak kan vara att företagsklimatet blivit allt tuffare.En process som under senare år fått ökat intresse inom företagvärlden samt kommer sätta stor prägel på denna uppsats är materialanskaffningsprocessen. Materialanskaffning beskrivs som en process innefattande samtliga de aktiviteter som krävs för att säkerställa att material tillförs en organisation.Syfte: Syftet med denna uppsats är inledningsvis att kartlägga samt identifiera brister i Holtabs materialanskaffningsprocess. Vidare är syftet att komma med eventuella förslag till hur Holtab kan reducera kvalitetsbristerna i materialanskaffningsprocessen för att på så sätt minska företagets kvalitetsbristkostnader.Metod: Denna uppsats är en fallstudie på Holtab AB.

To achieve a sustainable development, three aspects have to take equal place in the society; environmental, economical and social. To reduce the impact on the environment and the amount of greenhouse gases supplied to the atmosphere, industrialized countries and less developed countries must start cooperating. Also the use of renewable energy sources, like solar, hydro and wind power, have to increase.Wind power has great potential as a future energy supply. It is cost efficient, quickly developed and the resource is abundant and available worldwide.Examinations made in Sweden, indicates that there are difficulties establishing wind power at the same pace as the environmental goals, set by the Swedish government, requires. Mainly because people living nearby potential areas for wind power farms, appeal against the decision.This study aims to investigate differences between how people in Sweden and Brazil look at wind power as a future energy source and at the establishing process.

När en ny produkt lanseras på marknaden uppkommer det med stor sannolikhet brister som intetidigare upptäckts. Syftet med denna studie är att skapa en arbetsmodell för hur medelstora företagska hantera kvalitetsavvikelser som uppkommer inom produktion. För att skapa en realistisk modellför hur dessa kvalitetsavvikelser skall hanteras, baseras detta examensarbete på en fallstudie utfördpå ett tillverkande företag vid namn AQ ParkoPrint AB som är beläget i Gävle.Följande forskningsfrågor har besvarats för att understödja det huvudsakliga syftet:? Vilka kvalitetsavvikelser kan uppkomma inom medelstora företag?? Hur kan dessa kvalitetsavvikelser hanteras samt om möjligt reduceras?Metoderna som använts i studien är intervjuer och observationer. Fem intervjuer och tvåobservationer utfördes på AQ ParkoPrint AB.

Phosphate is a used as a surface treatment method which is used for various purposes in the industry. In this case, phosphate coated wire is used in the processes to achieve a desirable outcome. The reason to why phosphate coated wire is used in the production process is because phosphate acts as an accumulator, where it stabilizes the lubricant on the surface of the wire. Lubrication is important because it plays a major role in the roll quality and characterizes important benefits regarding the outcome.Currently, SKF has to wash away all phosphates residues after extrusion process in an operation called tumbling. The main reason for this is simply because the surface has to be completely free from lubricants and coatings till the next step of process.

Introduction: Child maltreatment, perpetrated by a caregiver, is a major health problem. The child suffers not only at the instance the abuse or maltreatment occurs, the consequences may persist into adulthood. The specialist nurse in child health (CHN), who works at a child health care unit, comes across almost every child growing up in Sweden. The CHN has an opportunity to implement primary prevention with the family during the child's first years. Aim: The aim of this study is to describe the CHN experiences regarding primary prevention to avoid domestic child maltreatment.

Today the human being see energy as a matter of course but the resources that is used for extract energy is today not enough for the world demand. Of all the energy that is used in Sweden today approximately 40 % goes to the building stock. This number will most likely increase if not necessary actions will be made on the already existing building stock since new houses constantly are built which will be added up on the already existing energy supply. This takes cause of action on the already existing building stocks, to fulfill the demands of the future use of energy that has been set by the authority. At the same time the thermal conditions cannot be influenced by the necessary changes that must be made.

The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.

Today most ice rinks in Sweden use secondary refrigeration systems with a solution of calcium chloride and water as secondary refrigerant. Due to the large amount of energy such a system uses more efficient systems would be desired.An earlier study concluded in the possibilities of using carbon dioxide as secondary refrigerant with copper tubes as the loops in the ice rink. Since then 3 ice rink refrigeration systems has been built with carbon dioxide in copper tubes. Excluding the ones being direct involved in those projects there is still very little knowledge about how these system works. This study has been made primarily with the aim of adding to the knowledge concerning availability and cost and secondary to look at possibilities for improvement.A comparison between systems with carbon dioxide, calcium chloride respective ammonium solved in water has been made by using Decision Matrix.

The aim of this study was to conduct an instrument test of the Canadian questionnaire Alberta Context Tool (ACT) version Long-Term care for Swedish conditions. ACT is designed in order to measure the context in the care environment and different behaviours related to the changes in clinical practice. In total, 159 Licensed Practical Nurses (LPNs) and Registered Nurses (RNs) within municipality care of the elderly were included in the survey. The test included the instrument's reliability and face validity.The reliability test was implemented through calculation of Cronbach´s Alpha, and showed internal consistency for five of the scales of the ACT-instrument with Cronbach´s Alpha values ranging between 0,728 and 0,873. However, three dimensions got lower values (0,558 - 0,683).The analysis was carried out with content analysis and carried out for LPNs and RNs in separate groups.

Competence Portals are software tools that are intended to make it easier for persons that have had no previous contact to find and contact each other.
