Förbättringsarbete mot Lean Production på Tooling Support Halmstad AB
Nowdays an efficient production is critical to achieve for companies competing on the market for steel cutting tools. One of such companies is Halmstad based Tooling Support Halmstad AB that manufactures threading-taps, threading-dies and parting off tools, towards a centralized warehouse in Schiedam, Holland. The large amount of different products, approximately 2500 is a big contributor to the problem along with a new order system that creates a demand of low setup times. Previously the company was forwarded orders through quarter based prognoses which enabled planning of the production over a longer time span. Currently the newer order system ZENIT is in use and the company thereby gets their orders weekly.
Vegetationens roll i erosiva vattendrag : en review och fältstudie av två nyckelområden i Rönne å
The vegetation?s impact on erosion control is widely explored, even though research? results are scattered where it suggests a both positive and negative relationship between roots and erosion tendency. Research has measured the roots? impact on erosion by many different methods, hence the aim of this study is to offer a clearance of what factors play an important role in the choice of appropriate species controlling river bank erosion. I have therefore
studied 17 articles concerning vegetation and erosion control, which were found in different databases such as: Web of Knowledge, Biological Sciences, Academic Search Elite and Google Scholar.
Det Intelligenta Huset : - En studie i hemautomation
Today all buildings contain some form of home automation. It might be heating controlled by athermostat or motion detectors controlling outdoor lighting.This paper,The Intelligent House, deals with the planning of a house in Kiruna, in the north ofSweden and further immerses itself in home automation or intelligent control in single-familyhomes. The house has been entirely planned, from layout to structural design and plumbing.The purpose of the paper has been to investigate the possibilities in home automation in singlefamilyhomes and to choose a suitable home automation system for the house being planned.The system has been designed and the costs and energy savings have been calculated.The system chosen for the house is called KNX and is the largest system for home automation inSweden. It is used to control heating, ventilation, lighting and alarm systems in the house. Is hasbeen found that KNX is very expensive and that the amount of energy, possible to save in thehouse, using the system, is relatively small.
Stopptids- och avvikelseuppfo?ljning vid la?nga takttider : Fra?n avvikelse till info?rd fo?rba?ttring
High quality within a Lean production system begins with standardised work, which creates stable processes able to generate predictable output. If nonconformity from the standard procedures occurs, routines are needed to analyse, correct and prevent the nonconformity from occurring again. In that way, the nonconformity can be a trigger for continuous improvements toward more stable processes. In takted production lines, where the operator follows a standard sequence with tasks set to be completed within the takt time, a nonconformity leads to downtime in the operator?s sequence, and no value is added.
Private equity - styrning av tre portföljbolag; En komparativ fallstudie av ett buyout-bolags styrning av tre portföljbolag
By identifying effects that a buyout-firm has on management control systems in its portfolio companies, the aim of this thesis is to explain how such effects differs between the companies and finally to explain why the effects differs even though the companies are owned by the same buyout-firm. The study is conducted as a qualitative case study based on interviews with representatives from the studied buyout-firm and three of its portfolio companies.By analyzing the empirical findings with frameworks and theories within management control systems and value creation, we cannot only identify effects that are common for all portfolio companies but we can also observe differences between the portfolio companies.The identified effects that are common for all portfolio companies are: increased internal reporting burden, increased perceived risk of getting laid off among managers and co-workers and replacement of the board immediately after acquisition.The effects that are observed only for two portfolio companies are: increased focus on short-term planning, higher financial targets, replacement of company management upon acquisition and moving of decision authorities to higher organizational levels. Differences are observed although the portfolio companies are owned by the same buyout-firm due to: differences in management and co-workers equity stake in the portfolio companies, differences in business complexity and differences in planned exit-horizon..

Chefers syn på administration inom stadsbyggnadsförvaltning
Denna studie syftar till att beskriva chefers syn på administration inom stadsbyggnadsförvaltning och att identifiera förbättringsmöjligheter inom administrativt arbete. Studien bygger på fem individuella, kvalitativa intervjuer och en workshop. I studien deltar fyra enhetschefer och en avdelningschef från en stadsbyggnadsförvaltning i Sverige. Till detta tillkommer en litteraturdel som baseras på bilden av chefsarbete, chefsrollen i offentlig sektor och två förbättringsstrategier Lean och Sex Sigma. I workshopen används Sex Sigma´s fiskbensdiagram som verktyg.
Informanternas syn på administration är framförallt att den anses som nödvändig.
Inokulering med två hjorttryfflar på arginingödslade täckrotsplantor i Gideå plantskola :
The effect of inoculation on containerized pine and spruce seedlings in a nursery with two
ectomycorrhizal fungi was investigated in regard to the development of mycorrhiza and plant growth. The fungi were Elaphomyces muricatus and Elaphomyces granulates and the inoculated seedlings were compared to an uninoculated control. These seedlings were all fertilized with arginine.
Five mycorrhiza species were found after DNA sequencing of the mycorrhizal root tips with different found morphotypes on seedlings from all treatments. Thelephora terrestris was the type which had the greatest distribution on pine seedlings and Tylospora asterophora was found at big extent on spruce seedlings. The inoculated species was not found, if it was due to the species hadn?t colonized the roots or if the DNA sequencing failed we can only speculate about.
Tredjemanskontroll - Säker rätt är säkert rättssäker : En studie med utgångspunkt i betänkandet Förbudet mot dubbla förfaranden och andra rättssäkerhetsfrågor i skatteförfarandet (SOU 2013:62)
SKV and Tullverket have several important tools and methods available in each activity to ensure that taxes and fees are paid and charged rightfully. Among other things they use tax or customs surcharges, targeted and general third party injunctions or targeted and general third party audits. The targeted controls, ergo targeted injunctions and audits, are targeted towards specific persons or documents while during the general controls these are not specified. The methods have repeatedly been the subject of discussions and attempts to simplify the tax procedure and increase the Rule of Law for the individual.The government appointed a commission on March 8 of the year 2012 with the assignment to prepare proposals to increase the Rule of Law in the tax procedure. The assignment was therefore to analyze the areas of tax and customs injunctions, reimbursement because of expenses and agents and also third party controls.
Stress is always present, Stress och coping hos personalen på en kvinnojour
The purpose of this study was to examine work related stressors and related coping strategies among case managers at a domestic violence shelter in the United States. We further wanted to examine whether locus of control among the participants could be related to work related stress and coping strategies. Qualitative interviews were performed with eight case managers to gain knowledge about the stressors and coping strategies they used by examining their thoughts, feelings and experiences. The result showed that the case managers experience a number of stressors in their work environment such as system problems (e.g., lack of re¬sources and time pressure) and emotional stress. Coping responses among the case managers included efforts to alter the problem, so called problem focused coping, efforts to control emo¬tions, so called emotions focused coping and social support from colleagues.
Halvledare för höga strömmar i fordon
Mechanical relays are more and more being replaced with semiconductortechnology. In this thesis it is investigated if and how the larger loads couldbe controlled by transistors. The main part of this work aims to create andverify a solution that can control the starter motor, as well as protect it incase of any failure. The different malfunctions that the solution protectsagainst is high current, too high peak current, low current, maximum cranktime and minimum cool off time. The timers also protect indirectly againstoverheating of the starter engine.The transistors used are BTS555, from Infineon.
Materialhantering i tillverkningsindustrin: En fallstudie som behandlar utformning och styrning av materialhanteringssystem
Materialhantering är den del av produktionslogistiken som hanterar det interna materialflödet, vilket innefattar intern lagerhållning och transport. Målet med den interna materialhanteringen är att säkerställa tillgången av material till produktionssystemet där hanteringen ska ske utan skador på material eller personal. I ett tillverkande företag kan en betydande del av den totala produktionskostnaden härledas till den interna materialhanteringen. Enligt Lean Production ska både transport och lagerhållning betraktas som slöseri. Det är därmed viktigt att effektivisera den interna materialhanteringen samtidigt som det inte får ske på bekostnad av sämre leveransprecision till produktionssystemet eller säkerheten.
Går det att ställa om en lina för axelbearbetning på 30 min? : En fallstudie på Scania Transmission, Södertälje
Tillverkningslinan för växellådans ingående axel har funnits i sitt nuvarande utförande sedan sensommaren 2013. Omställningstiden för linan översteg med råge det önskade, vilket ledde till långa stopptider och förlorad produktionstid. Under de förutsättningar som rådde hamnar genomsnittet för omställningstiden någonstans i intervallet 3-4 timmar, men tider kring 6 timmar hör inte till ovanligheterna. Målet med uppdraget var att, på den observerade linan, sänka omställningstiden till 30 minuter samtidigt som produkternas kvalitet bibehålls. Ett delmål under arbetets gång var att skapa förutsättningar för att tidsvariationen minskas samt att det definieras hur omställningstiden på linan ska mätas.
