Effektivisering av värdeflödet på ett producerande företag : En fallstudie på Klöfver AB

Denna fallstudie har utfört på Klöfver AB och syftet med studien är att öka förståelsen hur ett producerande företag kan effektivisera värdeflödet inom sina produktionsprocesser.Först kartlades det nuvarande läget i produktionen på företaget. Med utgångspunkt från en värdeflödesanalys kunde sedan värdeskapande och icke värdeskapande aktivitet identifieras. De icke värdeskapande aktiviteterna kategoriserades som olika typer av slöserier. Även övriga observationer visade att företaget jobbar på ett ostrukturerat sätt och att det förekommer en stökig miljö på företaget.I studiens slut genereras förbättringsförslag som grundar sig i studiens resultat och det beskrivs hur dessa förbättringsförslag kommer att påverka företaget. Undersökningsfrågan kommer att besvaras med hjälp av generella slutsatser som studien genererat..

Reducera omställningstiden i ytmonteringslinan Panasonic på Stoneridge Electronics AB

Omställningstiden i ytmonteringslinan Panasonic på Stoneridge Electronics AB ansågs vara en bidragande orsak till att maskinernas fulla kapacitet inte kunde utnyttjas. Syftet med det här examensarbetet var därför att analysera omställningssituationen och med analysen som grund reducera omställningstiden med hjälp av SMED-metoden samt ta fram förbättringsförslag gällande arbetet i övrigt.Förutom SMED har tidsmätningar, observationer samt litteraturstudier legat till grund för reduceringen av omställningstid samt förbättringsförslagen som innebär bl.a. sekventiell omställning av conveyersystemet i ytmonteringslinan samt tydligare instruktioner och mer visuell styrning, enligt teorin om Lean.Ett fortsatt arbete i form av uppdatering av arbetsinstruktioner och själva utförandet av omställningen är exempel på typen av ständiga förbättringar som företaget redan idag jobbar aktivt med..

Revisionsplikten försvinner - tänkbara konsekvenser ur kreditgivarens perspektiv

Purpose: To investigate whether or not the credit granters believe the quality in audits will deteriorate after the abolishment of statutory audit and, if that is the case, how the abolishment will strike the purpose and goal of accounting.Approach: To answer our purpose we carried out a literature study to later implement interviews with four granters of credits specialised in business accounts.Findings: The process of credit granting will not change after the abolishment of statutory audit for companies still using audit reports. Though, for other companies the process will change dramatically since the lean time of the process will increase. Higher demands will be put on these companies since the reliability in the economic information will decrease when it is no longer being reviewed in the same sense. Though, the credit granters believe that some form of substitute for audit will be demanded in order for the companies to be granted credits from the bank..

Det politiska i författningspolitiken - en idéanalys av riksdagsdebatten i anknytning till Grundlagsutredningen

This essay revolves around two questions: what is the nature of politics, and what kind of political order ensures a high rate of citizen participation? By using Cantal Mouffes theory on the political this essay shows how different understandings of the nature of politics can lead to diverging views on what forms democracy should take. Two such understandings are identified; one that sees the nature of politics as characterized by conflict and power, one that sees it as a space for cooperation in search for the common good. I trace these different ideas about the political in the parliamentary debate concerning Swedish constitutional reform. I conclude that the left-of-centre parties hold a view of the political closer to the conflict-perspective, while the green party together with the liberals/conservatives lean closer to the opposite view..

Bakhjulsupphängning, fyrhjuling

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.

Utveckling av 300 kg HD Lightlift för belysning och liknande laster

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. .

Studie till uppstartande av annonskatalog

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.

Systematiskt arbete för att hantera osäkerheter vid mätning : vid Q-Med AB i Uppsala

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.
