Visualisering inom Operativt Inköp
Visualization plays a key role in the concept of Lean. Lean was developed in Japan as a business philosophy in order to lead to an activity, where only steps that contribute to customer value of the final product are being performed. By defining the customer value and establish visualized standards, it is possible to see when situations differ from the standard. Then it?s possible to lead the process back on track.
Prognostisering av sortimentsutfall från stående skog med hjälp av befintliga data : anpassat till Sveaskog Norrbottens planeringsprocess
This study in the subject of forest planning is made for Sveaskog and its aim is to develop tools that prognosticate outcome in terms of volumes per sort from not yet cut forest stands. The degree of detail is just to get reliable results for at least one months volumes, for Sveaskogs own forestland in the market region of Norrbotten that is about 100 000 m3fub. The course of action to accomplish this is regression analysis and the data consists of cut tracts on own forestland in Norrbotten during the years 2006, 2007 and 2008. That is a little more than 4 million m3fub. Two tools were made.
Modellering och design av elmotor för mutterdragare
This thesis was carried out at Atlas Copco Tools and Assembly Systems. The purpose hasbeen to develop a design tool to be used for development of new electric motors for AtlasCopcos electric nutrunners. The focus of the thesis has been to increase productivity bydecreasing the power losses in an electric tool. The productivity is defined as themaximum number of tightenings a nutrunner can perform without becoming too hot.Before starting the development of this design tool an existing Matlab script, whichcalculates the losses in a slotless electric motor, has been studied and modified torepresent the real losses in a better way. The modification has been made by performingpractical studies of different losses and then adjusting existing parameters in the Matlabscript.Because design changes in one part of a mechatronic system can lead to a decrease inperformance of another part the choice of parameters that can be changed has been madeso that other parts of the system is affected as little as possible.A study of the existing tools efficiency during an entire tightening has been made toincrease the understanding of when and where the different losses appear and to comparethe modified Matlab script with the measured values.The design tool was formed so that it executes the Matlab script, that calculates thelosses, for a number of different design options and stores the alternative which producesthe least losses.

Lean i offentliga myndigheter.
Antalet nyanlända elever ökar i den svenska skolan, men nyanlända elevers skolsituation är ett område där den akademiska forskningen är underutvecklad. Studiens syfte är att öka förståelsen för hur undervisning och bedömning av nyanlända elever i ämnet hem- och konsumentkunskap kan utformas. Detta har undersökts genom intervjuer med fyra lärare som arbetar i två olika kommuner. Vid intervjuerna framkom att organiseringen av nyanlända elevers HK-undervisning skiljer sig åt på de olika skolorna, då eleverna börjar delta i HK-undervisning alltifrån första veckan i svensk skola till efter ett till två år. För att göra lektionsinnehållet tillgängligt även för nyanlända elever med bristande kunskaper i svenska används följande fyra strategier: delar av kommunikationen under lektionstid sker på engelska och/eller elevens modersmål, eleven får språkligt och innehållsmässigt stöd utanför lektionstid, läraren demonstrerar valda delar samt läraren anpassar uppgifter och redovisningskrav.
Bildskapande : En undersökning i hur pedagogerna på en förskoleavdelning ser på och bemöter barns bildskapande
This report describes a study of how educationalists, from one preschool group, approach to and respond to children ?s creative activity in preschool. To answer the survey ?s purpose I used four research questions, which is the following:-What function do the educationalists give the creative activity in the working?-How do they see the importance of thecreative activity for thechild and its development?-How doeducationalists considerthat theyrespond to the child's creative activity?-Is thereany norms surrounding creative activity in preschool?The theoretical base of the study is rooted in the sociocultural perspective, where creative activity and visual arts can be seen as mediating cultural tools. The method is a qualitative interview of five preschooleducationalists.
Produktivitetsanalys ur ett LEAN-perspektiv : En studie hos OPPC, AstraZeneca
The objective of this thesis is to map the resources and methods used at the department OPPC, at AstraZeneca, and derived from that give suggestions on possible solutions that will increase their productivity.Mapping of the product flow, as well as gathering of process data, has mainly been done using observations, but consultation with the process technicians has also played a great role. Further have theoretical methods been used, based on literature studies, within the areas of Lean production and statistics.The work has incrementally gone forward since the steps taken has been restricted by the irregularity of production which led to the need of creating a fictive production flow. This has affected the lead-time calculations in the way that they are meant to give an indication, rather than an absolute truth, on how different methods described shall be used.The current state analysis showed multiple areas of improvement when defining capacity as value adding time in relation to total throughput time. Using the "standard scenario" as a basis showed that the actual production flow only constituted 50% of the total project time. Further it showed that the workflow contained more non-value adding activities than value adding activities, which is a result of how the work is distributed within the department as well as in the different projects.
Hur oberoende aktörer kan erhålla synergieffekter genom logistiksamordning - En kvalitativ studie på en kemikoncern
Logistik fått en allt viktigare roll i dagens rationaliseringsarbete eftersom många av effektivitetsvinsterna ligger i gränssnitten mellan olika avdelningar och aktörer i värdeflödet. Därmed är det av intresse att studera huruvida aktörer kan erhålla synergieffekter genom samordning inom logistiksystemet. Då varje aktörs logistiksystem är unikt så har studien utförts i samarbete med en global kemikoncern på en utav deras fabriksområden. På området verkar i dagsläget sex oberoende aktörer, varav tre tillhör den aktuella koncernen och därmed är de som ligger i fokus för studien. De övriga aktörerna likväl de aktiviteter som inte är kopplade till logistiken har exkluderats ur studien.Utifrån det här intresset och samarbetet så har följande syfte formulerats: ?Syftet med studien är att utreda vilka potentiella synergieffekter som kan erhållas vid en samordning av aktiviteter och resurser inom logistikhantering mellan aktörer, som i dagsläget arbetar mer eller mindre isolerat ifrån varandra?.Genom en kombination av litteratursökningar med fokus på Lean och Nätverksmodellen samt en kvalitativ studie i form av datainsamling, flertalet intervjuer, noggranna observationer, processkartläggning samt en benchmarking har en analys gjorts.Analysen har lett fram till ett flertal rekommendationer där förbättringspotential finns samt förväntade synergieffekter som rekommendationerna kan resultera i.

Dessa är; Lean production, processorientering, flödesorientering, Time-based competition, Theory of Constraints, Supply chain management, Planering, Mål och mätmetoder, Patienten i fokus, Genombrott och Advanced access.
Effektivisering av ventilationsprojekt : Bravida Filial Uppsala
In recent years the construction industry has been exposed to increased time pressure which has resulted in a higher amount of wastage. Today 35 % of all construction projects in Sweden is "wasted". Time pressure has risen due to increased competition on the market, with more actors entering the construction business, therefore profit margins decreased which has led to a more pressing need for decreasing the amount of wastage.Bravida is Scandinavia's largest supplier of installations and provides specialist services in electrical installations (heating and sanitation), and ventilation. Mahdi Bawaqneh's task was to investigate where, how and why wastage occurs in the company's projects and how to prevent such wastage. The thesis covers the subjects of lean production, communication in projects and planning of projects.
Hur påverkar nationalkultur Lean-principernas framträdande? : En marknadsundersökning för Abou AB:s internationaliseringsprocess
The purpose of this paper is to examine how six students who attend a high school relate to their multilingualism and emphasize how their multilingualism has affected their views of themselves and their identity. The fundamental questions were:How do six students who attend a secondary school relate to their multilingualism?How has students' multilingualism affected their views of themselves and their identity?I did use a qualitative research method in terms of interviews to receive answers for my inquiries.Carla Jonsson (2010) speaks inter alia about ?the third space? which concerns adolescents creating a ?third room?. Almqvist (2006) believes that adolescents that are exposed to discrimination and prejudices can lead to them turning their backs on society in disappointment. Boyd (1985) has, in his thesis, found that multilingual students communicate with the majority language and with their mother tongue with their parents.
Att handskas med trender inom Logistik : Supply Chain Management
Logistikens vikt för företag blir allt större. En mängd faktorer i företagens omvärld tvingar företag att följa med i utvecklingen för att behålla sin konkurrenskraft. Den ständiga förändringen som sker inom logistikområdet präglas av en mängd tidstypiska trender. Företag med en betydande logistik tvingas därför ta ställning till dessa trender, som på olika sätt sätter avtryck i organisationer då de väljer att implementera tillhörande arbetssätt och metoder från trenderna.Studien undersöker hur företag påverkas av logistiska trender. Detta sker genom att beskriva hur de ser på utvecklingen inom logistik och de trender som utvecklas inom området, samt att se till hur trenderna har satt spår i företagens verksamheter.
Evaluation and Comparison of Ecological Models Simulating Nitrogen Processes in Treatment Wetlands,Implemented in Modelica
Two ecological models of nitrogen processes in treatment wetlands have been evaluated and compared. These models have been implemented, simulated, and visualized in the Modelica language. The differences and similarities between the Modelica modeling environment used in this thesis and other environments or tools for ecological modeling have been evaluated. The modeling tools evaluated are PowerSim, Simile, Stella, the MathModelica Model Editor, and WEST. The evaluation and the analysis have been performed using McCall?s factors for software quality (McCall et al, 1977), a correlation analysis and the Constant Comparative Method (Glaser&Strauss, 1999).
Microsoft Visual Studio och osCommerce - en jämförelse mellan två verktyg
This report represents a comparison between two different tools used to create an online store that was developed by two students at the Technical University in Jönköping. The web shop will be of great benefit to both customers and administrator in a food firm known as Mattias' Livs. The company wanted an online store that facilitates the sale section and gives a full control of their stocks. The aim of this thesis is to create an online store that offers customers the ability to shop online and help the staff to operate the company in a simpler and more efficient way, which reduces the need for human resources and thus leads to less costs for the company. The aim also includes a comparison between the two different tools used to create the online store.
Riskuppfattningar kring spårspring : Fokus på lokförare och personal på Trafikverket
Learning Management Systems (LMSs) hold great potential to support learning activities, for example by providing teachers and students with new and extended spaces for interaction and collaboration. However, this potential appears to be difficult to realize, and despite their perceived learning benefits, the reality is that LMSs are being used primarily for administrative purposes. Meanwhile, external pedagogical tools are successfully put into practice to improve learning outcomes, and the aim of this study is therefore to identify and discuss benefits and disadvantages associated with the LMS as a concept. By interviewing secondary school teachers, we disentangle the idea of integrating administrative and pedagogical aids into a single platform, providing detailed insight into the use of digital tools in secondary education. The study contributes to a deepened understanding of integrated learning environments, and we conclude that there is a conflict between structure and flexibility that needs to be addressed before determining the design of a digital learning space..
