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.

AbstractDegree thesis Solid content in Lime Mud By Andre Flodin Process operator program ? Umeå University 17/6 ? 2014 Pages: 21A thesis was made on Billerudkorsnäs production unit in Karlsborg where lime kiln in the causticising department of chemical recovery plant does not meet the required production. Causticising department is the final step in the chemical recycling unit. There, the filtered green liquor is mixed with lime to recover the cooking chemicals used in the pulp factory. The cooking liquid is called white liquor.

Business Process Modelling Notation (BPMN) is a way to graphically draw a diagram of a business process. A BPMN diagram consists of several so-called flow objects. These are interconnected in the graph through sequence  flows. BPMN models are merely graphical representations of business process and there is a need to simulate these diagrams for different purposes. The simulation that now is available for BPMN is that the model is evaluated by checking if it is correct.

The problem being examined is the disturbing noise that is created in an open plan office on a company working with a creative process, such as a newspaper or a communications agency. The purpose of this study was to examine the needs for today for a sound absorber in open offices and create and design a design proposal. The aim is also to develop a marketing material the product proposal. The problem has been broken down into the following questions:- How does the user look at the need of a sound absorber in an open offices solution today?- Does an interior designer apply sound absorbers when they furnish the intended environment? - How can a design that meets the needs that exists be achieved and to speak the user?The study is based on three choice of methods a literature review on selected topics that relate to the topic, an interview with an interior designer to explore how an interior designer applies absorbers in open plan office and finally an extensive survey that treats the user's needs and appropriate appearance for the product proposal.The design process has undertaken the following methods, design brief, requirements specification, functional analysis and sketches to produce the final product proposal.

In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.

The aim of this thesis is to describe and analyze the geographical distribution of everyday criminality in the town of Borlänge during the year 2002 and to analyze which measures to be taken in the physical social planning to decrease this everyday criminality there. The term everyday criminality is here to be understood as those categories of crime that appear most frequently in the records of reports to the police every year. Here two kinds of crime have been in focus, thefts from cars and office burglary.In fulfilling this aim two main questions have been answered. The first one is how the everyday criminality was distributed geographically in the town of Borlänge during the year 2002. The second one is which measures to be taken in the physical social planning to decrease this everyday criminality in the town of Borlänge.In order to answer the first question a spatial autocorrelation analysis, Local Moran LISA has been used.

Sewer trenches usually contain material with a higher hydraulic conductivity then the adjacent soil. Thus they can serve as paths of preferential flow in a polluted area. Wastewater from factories can also leak from wastewater pipes and pollute the soil in the sewer trenches.The purpose of this project was to investigate pollutions in sewer trenches and in sewer pipes in the industrial area of Köpmanholmen, 20 km south of Örnsköldsvik in the north of Sweden. To make an estimation concerning the potential of transport of pollutions in sewer trenches, hydrological calculations were performed.Leakage to any greater extent did not seem to be a problem in the area. This is the case both for the concrete and the wooden pipes that have served as factory wastewater pipes.

The purpose of this thesis for Sapa Heat Transfer is to examine a furnace in which aluminium is pre-heated before hot rolling. The project is modeled in a computer environment in which the air flow in the furnace and the heat transfer to the aluminium solids are included. The computer environment and its governing equations, as well as boundary conditions and generalizations, are presented and explained.The simulations are based on two models. The first model has an asymmetric solid placement, which is how it looks in today's ovens. It is validated against collected data.
