Due to increasing product availability and higher demands on fast deliveries, the competition between companies is growing. To be able to satisfy the customers? requests an efficient logistics system with short throughput time is required. By using tools associated with Lean production companies are able to make great improvements in their manufacturing systems and reduce lead times to satisfy customer demands.There are two classifications associated with manufacturing, high variety and low volume (HVLV) and low volume and high variety (LVHV). The general belief is that the concept of Lean production is difficult to implement in a production environment with high variety and low volume due to the concept being adapted to mass production.

Understensho?jden is Stockholm's largest eco-village which was built in the early 1990s with the vision of enabling ecological living for people. However the ecovillage is no longer considered as environmentally friendly because of its relatively high energy consumption, and non-updated energy system. The purpose of this study is therefore to investigate how Understensho?jden should reduce their energy consumption and upgrade its energy system by using Blower-Door, IR-camera and Design Builder.

Since energy simulations are used to verify that projected residential buildings will reach the current energy requirements it is important that the results are reliable.This report investigates the extent of uncertainty in energy simulations, estimates the causes of the uncertainty and its economic and environmental consequences.The method used in this report is based on three validation methods; empirical validation, analytical validation and comparative validation. The analysis was carried out for five multi-family dwellings in Uppsala with installed meters for energy measurements. One of these objects, Klockarlunden, was studied in more detail than the others.The results show that the deviations are between 10 and 29% for the studied objects, which means that the uncertainty is estimated to be at least 29%. All simulations underestimate the buildings need of energy. The simulation for Klockarlunden can predict the energy consumption to be within the range of 46-98 kWh/m2year with 90% confidence level based on the current uncertainty.

The purpose on this study is to determine the extent of possible connections between tendencies to increased violent behavior and increased alcohol consumption among a total cohort of girls in the 9th grade compulsory school and 2nd grade upper secondary school in a Swedish county. In 2004 the Epidemiological Department carried out a health-status survey, using a self-report questionnaire, with students from both private and public schools in a specific county in Sweden. All respondents (N= ca 4000), attending all compulsory (at 9th grade) and upper secondary schools (second tier) on the survey date completed the questionnaire. For this particular study, 9 questions from the questionnaire, all concerning self-reported violent behavior and alcohol consumption habits were used either individually or combined in index variables. The result showed that while violence experience is low among these 4000 girls, it increased in relation to a corresponding increase in alcohol consumption.

The study aims to reduce energy consumption in apartment buildings where individual metering and charging of heat is applied. The aim is to develop planning and design for individual metering and charging in apartment buildings.The study is based on literature review, interviews and case study that include analysis of existing documents. Interviews were carried out with the property developer and the involved consultants who planned the apartment building Yasuragi. To investigate the differences the condominium association has noted in heat consumption between flats, the debit values of the heat were used to discern which houses that were furthest from the average consumption. On these flats there were temperature measurements and thermal photo shoots made for discriminating behavior and possible construction techniques which could be the explanation for the heat spread.Boverket shows that the consumption of heat can be reduced by 10-20% after insertion of individual metering and charging in an apartment block.

- ABSTRACT ?Title: Winners of the Web ( Webbens vinnare)Number of pages: 35 (including enclosures)Author: Lydia KellamTutor: Else NygrenCourse: Media and Communication Studies CPeriod: Fall Semester 2006University: Division of Media and Communication, Department of Information SciencePurpose: The aim of the research paper was to see Internet and the digital techniques impact on marketing communication and consuming behavior on the Web. By understanding the relationship between marketing communication and consumer behavior my intentions were to comprehend how consumer behavior on the web could be understand. The purpose of this paper is to understand how different marketing activities on the Internet are followed by consumption.Material/Method: By using focus group interviews I wanted to study how individuals act on the Internet. How different activities such as communication and participation on the web could lead to consumption on the Internet.

This study examines the eWOM effect, more specifically: how customer reviews effects consumers. The study is based on a modified version of the Regulatory Focus Theory which describes consumer behavior using consumer consumption goals. The purpose of this study was to examine how positive and negative customer review's influence consumers when analyzing products that are equally characterized by two consumption goals: promotion and prevention goals. The authors combined quantitative (questionnaire) and qualitative (focus groups) research methods with the sample selection for both research methods being based on students of Södertörns University. Results indicate that negative customer reviews have a stronger influence on consumers than positive customer reviews when analyzing products that are equally characterized by the promotion goals and prevention goals.

AB Gustaf Kährs grundades 1857 i Nybro och 1947 blev Kährs först med att få patent på ett trägolv. Enligt Kährs är deras affärsidé att erbjuda miljövänliga och högkvalitativa trägolv för privata, offentliga och kommersiella miljöer. Under de senare åren har marknaden för robustare och mer formgivna trägolv vuxit. Därför har Kährs på kort tid byggt upp en ny linje för designprodukter. Det finns ett behov av att utvärdera och analysera linjen ur ett produktionstekniskt perspektiv med hjälp av olika LEAN verktyg.

The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.

De tankar om förbättringsprocesser som tillslut har blivit konceptet Lean härstammar ifrån ?The Toyota Production System? där Kiiro Toyodas vision att alla delar av en bil skall levereras precis ?i rätt tid? står i fokus. Delarna som arbetarna behöver skall alltså vara tillgängliga precis när de behöver dem varken förr eller senare. Det tog tid innan hans vision blev realitet men ett decennium efter hans död använder hela Toyota koncernen sig utav hans idéer över hela världen. Man kan se systemutveckling som en form av produktutveckling.

This report was performed in order to evaluate a new technological measure and focuses generally on a heat pump system to a HWC-washing machine. The client is Asko Appliances AB, a company well known for its environmentally friendly products. The goal of this study was to improve the energy efficiency of a washing machine by combining a heat pump device to the heater of the wash water, in order to reduce the energy consumed for heating the water. Besides reducing the energy consumption in heating the water, the washing machine was required to meet low noise and short operating time specifications. For that purpose, nine trials in three test series have been carried out.

As the final course in the education ?University Diploma Programme for Process Operators? there is a thesis in cooperation with a company required.This thesis is about operator maintenance and 5S made at Metsä Board in Husum.In this report you can read my opinions and conclusions based on literature studies and the interviews that have been made with the staff at PM6 (the paper machine).I chose to focus on the theory of lean, 5S and operator maintenance because it covers the area of this thesis.The operators shall do their rounds to make sure that the equipment works fine. They shall also write down things that they notice in a checklist. This is not done as it should be and the question is: can this be solved by using 5S?My conclusion of this thesis are:Better review of the task so that everyone is involved.

Bakgrunden till denna rapport är det stora antal vindkraftverk som det idag finns planer på att bygga i Sverige. I Jokkmokksliden utanför Malå i Västerbotten påbörjades byggnationen av en vindkraftverkspark under 2010 vilken kommer att bestå av 18 vindkraftverk ritade av en tysk konstruktör. Fundamenten för vindkraftverken är massiva gravitationsfundament där armeringen är särskilt komplicerad att montera och kräver en stor arbetsinsatts. Syftet med denna rapport är att undersöka om och hur man genom att tillämpa nya metoder och planeringsverktyg kan öka produktiviteten och därmed minska arbetsinsatsen. För att uppnå detta har en djupstudie inom Lean Production utförts.

Byggbranschen har länge kännetecknats av konservativt tänkande och höga produktionskostnader. Medan produkter i andra branscher ständigt förbättrats i hård konkurrens, med högre kvalitet och lägre priser som följd, har obenägenheten för förändring inom byggbranschen hindrat utvecklingen. Idag har byggkostnaderna nått sådana nivåer att en genomgripande förändring måste till för att vända kostnadsutvecklingen.Produktionsfilosofin Lean används oftast vid nyproduktion som ett sätt att leda branschen i rätt riktning och sänka produktionskostnaderna. Syftet med detta examensarbete är att utreda om Lean även kan användas vid upprustning och renovering. Lean härstammar från Japan där filosofin utvecklats hos bilföretaget Toyota.

Syftet med studien är att beskriva och förstå hur chefer upplever samarbetet mellan enheterna inom den organisationskultur de är verksamma i. Analysen baseras på semistrukturerade intervjuer med 11 chefer inom en sektor i en kommunal vård- och omsorgsförvaltning, som utifrån LEAN önskar samla sin personalstyrka mot gemensamma mål för att bättre kunna klara sitt uppdrag. Studiens frågeställningar syftar till att undersöka hur cheferna upplever kulturen inom sin organisation och enhet samt hur de värderar samarbetet mellan enheterna. Undersökningen, som tillämpar en kvalitativ metod med hermeneutisk fenomenologisk ansats, analyserar intervjudata utifrån kulturteori och symbolisk interaktionism, med fokus på gemensamma symboler och mönster.  Studien fann att cheferna har nog med sitt och deras upplevelse av samarbetet är att det präglas av konkurrens, revirtänkande och oförenliga perspektiv. Arbetet med att stärka organisationens gemensamma kultur har ännu inte uppnått någon märkbar effekt och de gemensamma symbolerna är få.
