Problem StatementAfter the hurricane Gudrun in January 2005 EON Elnät Sverige AB started the project KRAFTTAG, were 17,000 km of the airborne power grid shall be replaced with cables underground. The transformers in the airborne power grid shall be dismounted, renovated if necessary and then conveyed to stations, of type kiosk.Additional new transformers, more than planned, have been bought. This is due to the dysfunctional transformer flow from the demolished power supply to projects, were the new power supply is built, the general picture is complicated, since the reconstruction involves other companies and many employees at E.ON.PurposeThe purpose of this master thesis is to map and understand the existing transformer flow. The objective is to make a recommendation on how to increase the level of E.ON? s transformer recycling.Methodthe authors have worked with a system approach, including both qualitative and quantitative data.

This thesis includes a description of the project flow for our projects at Semcon. The emphasis is on designing a manual for elMaster Concept.The project flow provides several minor and major elements plotting schedules for this project and the establishment of a manual. When a schedule is drawn, lists and tables with components and connections can be created. This is done to better manage drawings and make changes. These diagrams and tables are used in product manufacturing, testings, controls.

AbstractElectricity consumption is a globally increasing problem caused by the high share of electricity produced in coal power plants. These contribute to high carbon emissions when only about 1/3 of the heat generate electricity and the remaining 2/3 of the heat cools off. Combined heat and power plants (CHP) have high efficiency because they use the residual heat for domestic heating. The CHP plant often use fuels from renewable resources, giving them a lower carbon footprint, but are also depending on the heat demand. If electric powered products such as drying cabinets convert to heat powered products more environmentally friendly electricity will be produced by CHP plants, which can supplant electricity, produced from coal power plants and reduce carbon emissions.

Det övergripande syftet med detta arbete var att skapa en övergripande sammanställning rörande ämnena flödesproblem och silodesign och specifikt ta fram riktlinjer för hur massflöde ska uppnås i silos för hantering av olika biobränslen. Dessutom syftade arbetet till att ta upp två autentiska exempel med flödesproblem och hur dessa kunde designas om för massflöde. För att ta fram riktlinjer har arbetet utgått från värden framtagna av Wu, Schott & Lojdewijks (2011). Dessa har sedan bearbetats i programvaran Silo Stress Tool skapad av Dietmar Schulze (2013) för att utvinna gränsvärden för massflöde beroende av egenskaperna internfriktion, väggfriktion och vinkel på silons ficka. Resultatet visar gränsvärden för massflöde för både cirkulära och rektangulära silos.

Value stream mapping is a tool that is frequently used by many different companies. It is a great tool used to achieve the work that follows the theories of lean production. The tool is used, however, only frequent on the factory floor and the method is also designed based on this type of use.An interest of applying the method on administrative parts of the company has occurred lately. Administrative parts of the company refers to the part that does all the planning such as purchasing, receiving orders, customer contact, contact with factory floor and other work that is made around the actual manufacturing. But the knowledge about applying value stream mapping on the planning part of the company is lacking because the method is relatively new.In this work, a comparison is made between the introduction of value stream analysis on production and planning.

In a time when milk producing farm businesses face decline in profitability it is of great importance to examine how the situation can be improved. This thesis is a study off efficiency in milk producing farm businesses represented by Swedish, Dutch and German farms. The aim of this study is to investigate whether any differences exist between companies in these countries. Moreover, the study includes a mapping of a number of factors that determine how efficient milk production can be managed. This mapping is based on a literature review on prior efficiency studies followed by qualitative interviews with milk production advisors as well as a questionnaire sent out to dairy farmers in Sweden.

Milkability or ease of milking, has higher importance today for Swedish dairy cattle producers after the introduction of milking parlours and automatic milking systems. Milkability is the cow?s ability to quickly milk out and be completely milked. There are several measures of milkability available. Today the farmer measures the traits subjectively in relation to the conformation scoring of the cow 30-270 days after her first calving.

Four different kinds of filter-materials with reactive surfaces have been studied concerning their capacity to absorb heavy metals in leachate from a municipal waste deposit. The heavy metals studied were: lead, cadmium, copper, mercury, chromium, nickel and zinc. The leachate contains high levels of dissolved organic carbon (DOC) and has a high pH-value along with a high buffer capacity. These characteristics of the leachate make it difficult to remove pollutants and require efficient filters. The filters that were examined in the report are blast-furnace slag with CaO, sand covered with iron oxides, olivine and nepheline.

When establishing a groundwater protection area it is of great interest to be able to estimate the transit time of the groundwater from different places of the aquifer to the withdrawal well. These estimates can be uncertain due to heterogeneities in the aquifer. As a part of the work to develop methods for a more certain delineation of protection areas, a tracer test was performed in an esker located 25 kilometres NW of the town Uppsala.The purpose of this master thesis was to perform, describe and evaluate the tracer test. Travel times from the tracer test should then enable comparison against stochastic simulated travel times of the groundwater in the area.Three dyes (rhodamine WT, uranine and naphtionate) and a salt (NaBr) were used in the tracer test. The tracers were injected in four different wells located 25 meters from a pumping well.

Today Scania give a high priority to the continuous improvements on the quality of their vehicles. To follow up the flaws in product quality, which are recognized by the repairs at the local workshops, material requests are carried through to be able to analyze the defects at the plant in Södertälje ? in purpose to improve the product quality. The material requests are also carried through to compensate the workshop for their expenses and to check that they are working according to the company?s warranty manual.Due to local routines and different distribution structures at the different markets the lead times and the costs caused by the flow of material are hard to estimate.

Examensarbete utfördes på CA-Verken i Sävsjö som bl.a. tillverkar hydraulcylindrar. De senaste två år har CA-Verken haft en kraftig ökning av omsättningen och det som står i vägen för fortsatt expansion är produktionen som har begränsad kapacitet.Målet med detta arbete är att studera CA-Verkens produktionsflöde för att kunna identifiera flaskhalsen/flaskhalsarna och därefter ge förslag på lösningar och förbättringar. Den teorin som har använts som grund till arbetet är Theory of Constraints (TOC). Intervjuer, företagets affärssystem och observationer har använts vid datainsamling.

The investigation was initiated because of the high workload of the sellers and, additionally, because the Tunadal sawmill has received low ratings in customer surveys. Thus,  two main approaches are adopted here,  the first being to investigate which of the three methods  of working, namely, market divided flow organization, function organizationand flow organization with collaboration, proves to be the most beneficial. The second is to investigate whether there is an available method to ease the daily work. A literature review has been made in order to determine more efficient ways for the sellers to work in the Tunadal sawmill. During the investigation, an in-depth investigation into the total quality management using a balanced scorecard as a management tool was conducted.

The Transport division is responsible for the internal transports on Sandvik MaterialTechnology AB. At the moment there is no clear picture of how the straddle carriers aremoving at the division Primary Products and if it is working in a satisfying way. It isimportant to see the whole picture of the transportation flow so improvements can be made.The purpose of this essay is to survey and analyse the truck flow in a Lean Productionperspective. The essay is delimited to only include straddle carriers transportation ways in thePrimary Products division. To survey the truck flow we have used a method called Walkthrough.This means that we have walked thorough the whole production flow andinterviewed some of the employed on the way to get the necessary information.

Dagens konsumentbeteende online skiljer sig åt från hur det såg ut för bara några år sedan, någotsom kan förklaras av att både e-handel och Internet ständigt utvecklas och vårt köpbeteende ochvåra preferenser tenderar att förändras över tid. Den tekniska utvecklingen gör attkonsumentbeteendet inom e-handel tenderar att växla snabbt vilket gör kontinuerlig analys avkonsumentbeteende till en nyckelfaktor för att lyckas inom e-handel.Studien syftar till att undersöka det något yngre kvinnliga segmentets, i åldern 25-34 år,konsumentbeteende inom e-handel idag. Flow är ett använt begrepp för analys avkonsumentbeteende och har visat sig påverka både attityder och avsikter avsevärt inom virtuellamiljöer som exempelvis e-handel. Flera definitioner på begreppet tyder på en viss komplexitetoch att tillståndet tenderar att förändras och växa i takt med utvecklingen. I studienkonceptualiseras flow i kategorierna koncentration, njutning och förvrängd tidsuppfattning, där viundersöker hur de påverkar webbsajters användarvänlighet och konsumentens upplevdabeteendekontroll, och vi fokuserar på konsumentbeteende online i form av impulsköp och avbrutna köp då vi önskar analysera om beteendena påverkas av ett flow-tillstånd Via en enkätundersökning med kvinnliga studenter från svenska universitet visar våra resultat attflow i form av njutning och förvrängd tidsuppfattning ökar impulsköp, medankoncentrationsnivån inte har någon påverkan på konsumentens impulsivitet.

By studying a place or a phenomena research contributes to the creation of the image of the thing that he or she studies. Also, planning is seen as a democratic tool, a way to ?make? democracy. In order to see what democratic ideals that is being express it becomes important to study the research about democracy in Botkyrka. It is from this thinking this study about democracy and research has been formed.
