Outsourcing ? Ett verktyg för resurseffektivitet?
AbstractOutsourcing is a business strategy that has developed over the last 40 years. Outsourcing means to let another company do some activity within the company, for example production.The thesis for this paper is: How is outsourcing used in a manufacturing company today and how is the resource efficiency affected by it? The research is divided into two parts, a theoretical part and an empirical part. The theoretical part consists of a study of literature. The works in this study is books, text books, bachelor thesis paper and scientific articles.
Förändrad markanvändning vid biodrivmedelsproduktion : en empirisk undersökning av svenskproducerade biodrivmedels påverkan på åkermarkens användning
Increasing the use of biofuels is an important part of achieving the EU?s target of 10 percent
renewable energy in the transport sector. However, the competition between biofuels and food
production is an ongoing concern. Also, several studies have indicated a significantly higher
climate impact than was earlier estimated, due to emissions from land use.
In Sweden, both the use and production of biofuels from crops have increased substantially
during the last decade. The purpose of this project is first to present an overview of the Swedish
land use in all sectors.
Produktivitetsförbättringar : - förhöjning av produktiviteten vid mekanisk verkstad genom förkortade transportsträckor och standardiserad bearbetning
The aim of this project has been to raise the production efficiency of Daliff Precision Engineering through reduced transportation time and a more standardized manufacturing process. The problem has upraised because of a big and diversified product flora without any standard products and with just small batches ordered. The report also tries to show the work procedure with general analytical methods and be an example of how a similar problem can be resolved. The transportation time is being proposed to be reduced through a change in the layout of the factory. By moving a few manual machines, dispatch and burring to more efficient locations, the total transportation time will be reduced by 55 %.
Prefabricerade passivhusväggar
Background: The most energy efficient houses today are so called passive houses. These houses achieve high energy-efficiency partly by having well insulated walls. U-value describes the amount of heat transfered through a building element, the more insulation, the smaller U-value. A typical passive house wall have a U-value of 0.10 W/m2,°C. The passive houses are primarily made as small family houses and not as a block of apartments.
New Business Model for District Heating Firms Stabilizing the National Energy System with a Future Variable Electricity Production
The aim of this thesis is to develop a new business model for district heating and cooling firms which can contribute to a stabilization of the Swedish national energy system. The business model is developed for a district heating and cooling firm and is exemplified with Fortum Heat. The theoretical investigation around the topic creates a rigid base for following qualitative empirical studies. Osterwalder?s canvas for business model generation is used together with a Casual Loop Diagram to identify a number of business opportunities which stabilizes the national energy system.
Scenarioanalys över Sveriges elproduktion år 2050 : Kan Sverige försörja sig med 100 % förnybar
The aim of this report was to investigate if Sweden can have 100 % renewable electricity production in the year 2050. The conclusion is that it is possible but under certain conditions. For instance wave power must be in commercial use. When wind power and solar power represent a large percentage of the electric production there will be a lack of electric power during the winter but during the summer there will be a surplus of electric power. Both the surplus and the lack of electric power need to be taken into account.
Används både formativ och summativ utvärdering i ett projekt?
In companies today, it is becoming more and more common for employees to work in a project based environment, as a result many companies have developed their own project models. Companies with a well developed product culture are striving to improve their existing models, and businesses relatively new in the marketplace are aiming to reach a high level of maturity as well as reach high levels of efficiency in the shortest time possible. As the number of mature and efficient companies with well developed project model increase, so does the level of competition in the market. Since a well developed project model often leads to a more efficient and accurate way of carrying out the project, which in turn leads to shorter delivery time towards the client. This is crucial as time is one of the most valuable parameters of competition in today?s business environment.
BIM i produktionsskedet
This thesis treats Building Information Modeling, BIM, in the production stage. Brieflydescribed BIM is virtual model of a building object where all information about theobject is gathered. All the involved operators in the construction project have access tothe model and can gather or share information about the project. There are several waysto apply BIM in the production stage. This thesis primarily deals with visualization of theobject, preparation and planning, the ability to take amounts from the model andcoordination and clash control.The basic issue was highlighted by Byggdialog AB.
EFFEKTIVISERING AV INTERN MATERIALHANTERING
Considering that the current technology is constantly improving, it becomes increasingly important to have an efficient logistics in a company to maintain profitability while achieving a competitive business. Efficient logistics may be accomplished by improving the internal materials handling. In this thesis the internal material handling of steel frames has been studied at a factory in Vaggeryd. The goal of this study is to investigate the problems that exist with the current production flow of products and provide suggestions on how it can be developed to reduce unnecessary handling and movement.The study has a deductive approach where the authors has been using literature studies parallel with empirical analyzes conducted at a company to achieve the purpose of the study. Documentation from the company and interviews with staff and observations form the basis for the data collection carried out.
Vad skulle få en lantbrukare att ställa om från konventionell till ekologisk mjölkproduktion? :
The Swedish government has proposed that 20 % of the cultivated land in Sweden should be organic by the year 2010 (The Swedish Board of Agriculture, 2008). In addition to this the production of organic food like milk, meat and egg should increase considerably. To reach the government?s goal it is necessary that the Swedish farmers get motivated to convert their production from conventional to organic. Milko is a dairy association that has chosen to focus on organic products, they want to be the leading organic dairy association, and therefore they have a large need for organic milk (Milko, 2008).
Föryngringsresultat och beräknad virkesproduktion i naturligt föryngrade tallbestånd i Västerbotten under mitten av 1990-talet :
According to the Board of Forestry, in Västerbotten, many natural regenerations of Scots pine (Pinus sylvestris) carried out on privately owned forest in the middle of 1990 in Västerbotten have rendered a bad regeneration outcome and will provide a low future forest production. The Board of Forestry believes that the negative result can be explained by the fact that the regeneration has been carried out in wrong locations and that scarification failed to work as planned. In order for an accepted rate of regeneration the guidelines of the Forrest Act require, not less than 10 years after final cutting at natural regeneration, that there should be at least 1300 (site indices 16 m) - 1700 (site indices 20 m) main crop stems per hectare. Main crop stems are defined as stems according to the place of growth and appropriate tree type, in addition with regard to quality, stage of development and damage risk have a prospect of succeeding. In addition main crop stems should be separated by surface so that the proportion sample plots with 3 meters radius, and lack main crop stems, are not more than 10 % of site indices 14 meters or higher.
BPR och TQM: jämförelse mellan teoretiska modeller och dess tillämpning
Managementmodeller med inriktning mot processorientering blev populära i slutet av 1980-talet och början av 1990-talet och ett flertal olika modeller togs fram, marknadsfördes ivrigt av konsulter samt implementerades i många företag. Några av dessa modeller fick större genomslagskraft än andra. Många av dessa modeller blev så kallade managementtrender som fick stor uppmärksamhet under en period men sedan försvann. Litteraturstudier förde oss in på att Total Quality Management (TQM) och Business Process Reengineering (BPR) är två modeller som rönt stor uppmärksamhet. Det som intresserade oss vid litteraturstudierna var att studera hur dessa modeller upplevs i näringslivet idag, 10-15 år efter att de slagit igenom.
Kadmium i skånska vattendrag : en metodstudie i föroreningsmodellering
Modelling of pollutants is commonly used in research and at departments working with environmental issues. The need to use large amounts of data when modelling creates the opportunity for more generalised models with lower data demands. Aggregating functions into coarser elements is a sort of generalisation of actual features in nature.A development of a method and a modelling tool called ?KadmiumKalkylatorn? has been performed to model cadmium pollution in rivers in Skåne, Sweden. The water runoff has been multiplied with cadmium standard concentrations based on membership in landuse classes.

High Orbit Ion Cannon : Går det att skydda sig?
The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.
