Lean is a production philosophy which is about increased resource use while meeting customer requirements. The foundation of lean comes from Toyota and their production philosophy The Toyota Way. Professor Jeffrey k. Liker has worked with Toyota's production philosophy and Lean for a long time and has created a 4 P model and 14 principles that characterize the Toyota production system (TPS), which many sources refer to.The aim of my work is to study the working procedure of asphalt projects from sales to the laid asphalt with a focus on planning and production management. The goal is to examine how the lean philosophy can be applied in planning and production to simplify the flow of asphalt projects based on Likers model and principles.

In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.

Highland Group AB was helping a customer of theirs to create an All-Terrain Vehicle (ATV), a project Highland has never been involved with before. For the wishbone arms of the wheel suspension, traditional manufacturing methods and tubes with cylindrical or square shaped cross section was preferred. We performed a simulation where the ATV was driving on a bumpy road too see the forces involved. With the results we proceeded to calculate the strength of the concepts to find out which is best suited for the tough environment in which the ATV is used. The concept that turned out to be the best was a wishbone made of circular cross section, which had good structural strength and did fulfill the demands that we required for the construction.

The aim of this project is to examine the needs and problems that exists amongst homeless people and to develop a solution that will help them in their everyday life. Since the homeless are a relatively large vulnerable group i Sweden, their everyday lives could be made easier in many ways.A clear definition of the target group is put together to create a good starting point. What state and help orginazations do to help the homelss and the society?s view of the homeless is also relevant and has been documented. Four personal stories have been put together to desicribe cases of clear problems existing in everyday life.Several interesting problems has been defined from the research and acceptance in the communtiy, desire to be seen and heard and a lack of confidence were the main needs.

This report describes honey, its origin, properties and effects on human health. Honey has been used for a long time in most civilizations and apiculture is an important activity sector in many parts of the world. The trend is an increase in honey production but a decrease in the number of beekeepers in Sweden. Honeybees live in a highly developed society with a strong hierarchy and a well organized distribution of the tasks. They visit a broad spectrum of plants and collect nectar to store it as honey.

The company LightLift Esystems AB manufactures patented motorized lift systems for the illumination of halls with high ceilings. The company wants a new design for singular heavy lights in order to be more competitive.This project consists of the development of the new design under the requirements and specifications imposed by the company. The new design must support lights up to 300kg and keep the overall dimensions as low as possible without modifying the driving unit.This document contains all the designing steps followed to reach the final solution as well as the material selection, manufacturing process and assembly of all the parts that form it.The solution obtained shows to be very competitive with other alternative products, since this new design triples their maximum load capacity while the dimensions are very similar.In this context, the optical appearance was also very important to the company and so it was another main objective of this project. From an aesthetical point of view, the final solution proves to be very compact and versatile since it can either be hidden behind a false ceiling or covered by a plastic case that gives the design a very nice look.Finally, the solution achieved fulfils all the requirements and specification previously imposed. It is reliable, compact, cheap to manufacture, easy to assembly and it has a good optical appearance. .

This essay examines the recent electoral success of the Sweden Democrats (SD) in the Swedish municipal election in 2006 and 2010. By using statistical methods it aims to explain which of three contradicting theoretical frameworks best can explain how a populist radical right party could penetrate one of the most stable party systems in the world. The theoretical approaches tested in this essay are: a demand-side, an external supply-side and an internal supply-side approach. By using theoretically anchored proxies to determine the effect of the contradicting theoretical approaches this essay concludes that the internal supply-side explanation measuring the local party organizational ability of the SD had the most substantial effect when it comes to explaining their recent electoral success in the Swedish municipalities, as opposed to a more commonly believed demand-side driven explanation..

The purpose of this report is to study the risk of dust explosions at the candy manufacturing plant Leaf Sverige in Gävle, Sweden. The risk analysis was conducted with a preliminary hazard analysis, PHA and event trees. The analysis focuses only on the risk posed to employees and material damages at the plant. No third person injuries have been considered. Another purpose of this report is to study risk awareness and risk communication concerning dust explosions.

The transportation sector is the only sector of the Swedish society that is still increasing the emissions of carbon dioxide and other green house gases. Diesel fuel represents one of the fuels that contributes to these emissions and the use of diesel fuels is increasing every year. The main purpose of this study was to make an estimation of the current business situation for producers of liquid diesel biofuels in Sweden such as biodiesel, synthetic diesel and crude tall diesel and examine the forces of competition of the industry today and its future prospects. The study revealed that the rivalry among the existing firms was low mainly due to the geographical spread of the companies. Moreover the success of the biodiesel industry was influenced by a long-term guarantee of the tax exempt for biofuels and by the price level of petroleum diesel.

Sten Jonsson wants to start a production of an advertising catalogue for small companies in Sweden. Acatalogue where the advertisingcost is so low that most of the companies can afford to participate. Thecompanies who will advertise should be manufacturing companies in trades of carpentry, sheet metalworkshops, forging workshops and engineering workshops.The catalogue will facilitate for the manufacturer to reach the costumer without any middleman.Without a middleman creates a possibility for an opinion about the product at the same time as theprice can be held low. A catalogue of this type would benefit the marketing of the companies at the sametime as it would generate an occasion for innovations.The possible target groups are property companies, construct companies and farmers.A market research has been carried out contained a postal interview and a phone interview. Themarket research carried out to get an understanding in what the companies think about the idea butalso to see if the companies are in interest of advertise in the catalogue.

This report is about helping Q-Med AB in Uppsala to start its implementation of uncertainty of measurements analyses in their manufacturing department. Prior to this, the company relied solely on personal experience or did not take this uncertainty into consideration at all during different kind of measurements, which means that some of the processes that the company previously believed were within specified acceptance limits, will actually fail when considering these sources of uncertainties.Q-Med AB needed some sort of instruction to help the company, in a systematic way, to investigate different types of disorders that are affecting all kinds of measurements. This instruction includes a short summary about measurements and uncertainty of measurements in general and a detailed procedure about how these uncertainties are going to be handled in their daily work.The goal was to be able to use this instruction to systematically locate, eliminate (when possible) and analyze all kinds of disorders when measuring. Q-Med is using a lot of different types of instruments when measuring different types of quantities, including temperature, mass, pressure and density. This instruction will hereafter be used for every instrument, regardless of quantity and type of instrument.The instruction is tested through 4 different kinds of measurements, for mass, temperature and humidity.

This thesis is based on an assignment from a unit within an international group manufacturing industrial products. The purpose of the thesis is to analyze and suggest ways to improve the cost accounting system in use at the unit. The main source of empirical data has been interviews with employees. The theoretical framework is based on a comparison between traditional/standard costing and activity-based costing (ABC). The cost accounting system in use is described in detail and classified as a traditional/standard cost accounting system.

The purpose of this study is to research whether or not gender has an impact on assessments regarding the support for persons with special nedds (LSS personkrets 3). Administrators working in disability care are to make decisions on the basis of the individual's needs when assessing the need for aid and support. This study is based on qualitative interviews, with six administrators, and one head of operations. The empirical data collected has been thoroughly analysed from a gender perspective, rooted in Butler's theory regarding performativity and subversive actions, as well as Connell's gender regime, and Hirdman's gender contracts. Results show that administrators have ackknowledged and noticed differences in how male and female users express their needs, where the difference lies in the communication; females seem more reserved and shy, whereas males seem more outward and extroverted.
