Förstudie av utformning av avdelningarna Påspack och Förmontering, Volvo Penta Varafabriken

Sperr, Claes-Håkan January 2008 (has links)
På Volvo Pentas Varafabrik planerades det för att bygga om sitt måleri. I ombyggnadsskedet behövdes mera yta för att kunna hålla produktionen igång. Därför skulle avdelningen Påspacken flyttas till en annan plats i fabriken. Syftet med studien var att planera denna flytt och försöka effektivisera arbetet. Då den nya ytan var mindre krävdes det att arbetsplatserna och den totala layouten komprimerades. Den nya layouten skulle eventuellt påverka den intilliggande avdelningen Förmonteringen varför även den studerades. Efter ett antal veckor beslutades det att Påspacken inte behövde flyttas, ytan för måleriprojektet skulle ordnas på annat sätt.Efter detta besked fick arbetet fokuseras på Påspacken och att hitta effektivare arbetssätt och arbetsplatser. För att hitta verktyg att arbeta efter studerades Lean Production och dess teorier om olika slöserier i produktionen. Sedan studerades framför allt den truckkörning som utfördes då denna var en stor del av det icke värdeskapande arbetet.Arbetet visade att genom att flytta lagringen av material till fasta platser närmare avdelningen och att låta material till ofta förekommande satser stå framme på en arbetsplats kunde användandet av truck minska. Som ett exempel skulle truckkörningen vid plockning av satser till Målning-pack kunna minskas med 6,5 timmar/vecka. Det är ca 6 % av den totala tiden för dessa satser som är 103 timmar/vecka. Att investera i en hissautomat och lagra in material till de mest frekventa satserna i den skulle också minska truckanvändandet. För att frigöra yta på avdelningen men även minska på pallhanteringen skulle beställningar från Målning-pack kunna göras med hjälp av Kanbankort istället för att skicka hela tompallar.Några förslag på utformning av arbetsplatser har också lämnats i rapporten.

Avvägning mellan ordersärkostnad och lagerhållningskostnad i processindustrin

Näversten, Marcus, Bengtsson, Johan January 2010 (has links)
Lean Production is used by many manufacturing companies. Companies in process industries do not use Lean Production to the same extent today. This is part of the report's issue to explore how Lean Production can be applied to a company in the process industries. The investigated company is a processing company that manufactures various types of foil. The company wishes to streamline its production and has therefore asked the authors to examine if Lean Production can offer the company improvements in their production. Lean Production value stream mapping tool has been selected to identify and analyze the current state of two of its products in production. From the survey cost estimates was carried out on the basis of proposals for improving production. There were also theoretical frameworks used to examine the benefits that Lean Production can give a company in the process industries. From the results it is clear that the company in the current situation does not achieve any economic benefit of reducing their inventory costs. This is because the startup costs are greater than inventory costs. However, the authors found that a company in the process industry has much to gain from the Lean Production philosophy. The authors found some of the tools used in Lean Production difficult to implement, but the philosophy and thinking were considered to have a lot to contribute to a company in the process industry.

Förståelsen för OK>1 / The understanding of OK>1

Kjellberg, Ewa January 2010 (has links)
In 2005, Outokumpu began to implement its system of continuous improvement, OK> 1, at Avesta Jernverk. OK> 1 has not generated sufficient results on plant KPI:s. The purpose of this study is to identify the understanding,  participation and commitment regarding to OK> 1, and to suggest some actions to make OK> 1 more successful with emphasis on these three aspects. The thesis shall also determine whether there are any differences in the attitude towards OK>1 between Blue Collars and White Collars. The study consisted of a survey, and interviews. The output from these methods were processed and analyzed and finally resulted in a SWOT – analysis and suggested actions for improving the understanding, participation and commitment towards OK>1. The thesis work also covered a literature study concerning Lean Production, to get a deeper understanding of how to implement Lean Production successfully. The results of the survey pointed out that Blue Collars do not understand OK>1 as well as White Collars, and that they do not participate as actively as White Collars in improvement activities. To improve the results on plant KPI:s the thesis suggests following actions: education, simplification of methods and increased feedback from the management.

Green and Lean Production Visualization Tools; A Case Study exploring EVSM /

Darvish Shahrbabaki, Shahab Aldin January 2011 (has links)
There is a great need for an environmental, economic and social sustainable society, meeting the needs of the present without compromising the ability of future generations. Focusing on environmental sustainability, legislation and industrially accepted emission targets have emerged, on an overall level represented by e g the Kyoto protocol. Green as well as Lean production has thus become a more and more important topic in recent years. Based on the gigantic need for technologies and strategies that will reduce CO2 emissions globally, as well as customer demands for cost efficient and environmental friendly goods and processes, companies are starting to change their principles towards Green and Lean philosophies. In Green and/or Lean development, like other systematic approaches towards improved processes, there is a need for visualization tools to be used to analyze the supply chain and the manufacturing system. One possible visualization tool for this purpose is Environmental Value Stream Mapping, which has all the characteristics of its parent, VSM (Value Stream Mapping) and additional kaizen elements. In the EVSM, the environmental issues and the usage of material or energy have been added to the established VSM tool. However it has been almost four years since United States Environmental Protection Agency (USEPA) has introduced EVSM and there is no reliable evaluation how this tool really works and can be implemented. Therefore there is a need to evaluate and possibly improve this tool, based on practice and the applicability in industry. A case study has been performed testing the EVSM tool in industry and is presented in this paper. The aim of the case study is to analyze how the EVSM tool can be used as well as implementing suggested changes, summarized into, an Environmental Flow Process Chart. The EVSM tool seems suitable for showing the parts of the process in the supply chain which has more waste of energy or material. Still, it lacks information about where and how this waste are generated and which element of the process that is making the most waste, indicating a need for improvement

A study of lean production influences manufacturing performance

Hung, Shih-Feng 21 July 2011 (has links)
Lean production has taken root in Taiwan for many years, but with the rapid environmental changes in this shortening product life cycles, many goods emphasize on customization, Manufacturing in Taiwan need to convert their competitiveness, taking into account manufacturing performance such like quality, cost, speed and flexibility. In this study, the survey respondents on the concept of lean production level of acceptance, and the use of lean manufacturing practices in the degree of implementation. Collected data using SPSS statistical analysis to summarize the discussion, some conclusions of this study are as follows: First, the flow of production is the most important issue in operating performance. Second, statistical process control is proved to be an important tool for the study. It is highly involved in product quality and speed-related performance. Third, flexible industries pay more attention on modular and lead time. Fourth, when resources are limited, companies need to choose the more resources into the environment in which to do to improve. When the verification needs of operating performance of the different properties of different lean techniques to do investment, companies can be more concentrated in certain blocks and techniques have reached multiplier effects.

Vilka förändrade behov skapar Lean i ekonomistyrningen? : En fallstudie på Kretskort AB / What changed needs does Lean create in management accounting?  : A case study on Kretskort AB

Mattiasson, Pernilla, Jonasson, Emma January 2013 (has links)
Bakgrund: Det finns ett samband mellan ett företags produktionsfilosofi och utformningen på ekonomistyrningen som nyttjas. Ekonomistyrningen är dock trögrörlig och förändras oftast inte i samma takt eller utsträckning som verksamheten. Detta kan skapa problem då de initiativ som företaget vill genomföra får bättre genomslagskraft om de stöds av ekonomistyrningen. Kretskort AB har påbörjat en implementering av Lean och har ännu inte sett några förändringar i ekonomistyrningen. Efter de förändringar som har skett borde det dock finnas behov för en anpassad ekonomistyrning.  Syfte: Syftet med denna studie är att fastställa vilka behov av förändrad ekonomistyrning som har uppstått vid implementeringen av Lean vid Kretskort AB. Vidare syftar studien att svara på hur Kretskort ABs ekonomistyrning kan utformas för att på ett bättre sätt stödja Lean i framtiden.  Metod: För att uppnå studiens syfte genomfördes en fallstudie på en stor kontraktstillverkare av elektronik. Undersökningen är kvalitativ och datainsamlingen genomfördes med hjälp av intervjuer med ett flertal anställda på Kretskort AB.  Resultat, slutsatser: Trots att Kretskort ABs ekonomistyrning på många plan var stödjande för Lean redan innan implementeringen har vi ändå i studien funnit flera behov av förändringar i denna. Förändringarna gäller många delar av ekonomistyrningen där vissa redan tillgodosett medan andra kvarstår. / Background: There is a connection between the company's production philosophy and their management accounting. However, the management accounting is sluggish and does not change at the same rate or extent as the business does. This can create problems since the intiative will have a better chance of working if the management accounting supports it. Kretskort AB has started implementing Lean but has not yet seen any changes in their management accounting, however after the changes there might be a need for a customized system.  Purpose: The purpose of this study is to affirm the need for change in management accounting that has arisen since the implementation of Lean had begun at Kretskort AB. Furthermore, the study aims to answer how Kretskort ABs management accounting can be designed to better support Lean in the future.  Method: To fulfill the purpose of the study a case study was conducted on a large contract manufacturer specializing in electronics. This is a qualitative study and the data collection was conducted through interviews with a variety of employees at Kretskort AB.  Result, conclusions: Although Kretskort ABs management accounting were supportive of Lean before implementation the study still found a need for change in several aspects of their management accounting. The changes can be found in a variety of places in the organization and some have already been met while others remain.
