Plan för implementering av strukturerat underhållsarbete på Valmet ABs gjuteri i Karlstad
Rapporten handlar om att sätta upp en plan för implementering av ett mer strukturerat underhållsarbete på Valmet ABs gjuteri i Karlstad. Arbetet görs i kursen examensarbete för högskoleingenjörsexamen i maskinteknik på Karlstads universitet under våren 2014.Valmet har nyligen köpt upp gjuteriet på Lamberget i Karlstad. Där är det ett mycket eftersatt underhåll och finns i nuläget inte någon bra struktur på hur de arbetar med underhåll. Underhållsverksamheten är i behov av att systematiseras och integreras i Valmets övriga underhållsorganisation.Syftet med arbetet är således att utarbeta en plan för att strukturera underhållet på Valmets gjuteri i Karlstad.Arbetet är indelat i tre faser.- Nulägesanalys genom dels intervjuer av underhållspersonal samt kartläggning av utrustning- Skapa en målbild över hur man vill arbeta med underhåll, genom studiebesök hos andra liknande verksamheter, diskussioner med ledningen samt litteraturstudier.- Upprättande av plan för hur man ska ta sig dit. Vilka aktiviteter som skall utföras samt i vilken ordning, där bland annat lämpliga mätetal ska tas fram.Arbetet är baserat på metodiken TPM (total productive maintenance), det handlar dock inte om ett fullständigt införande av TPM utan begränsat till valda delar.Utifrån intervjuer med underhållspersonalen på gjuteriet samt observationsstudier och en kartläggning av maskinparken har en nulägesanalys gjorts.
Expander : En studie av Expanders kommunikation och varumärke
Communication can be heard in many different ways and it is important for all businesses, especially in B2B. The construction and maintenance of a brand plays just like the communication a very important part. These parts also have a lot to common and affect each other in a large extent. One problem that may occur in many companies is the failure to grow and gain a larger share of the market even if they in various ways are trying. Expander is one of those companies and in this research report we studied communication and brand building, focusing on brand management, relationships and integrated marketing. Here we drew the conclusion that all these areas are important for a company, especially in the Business-to-Business marketing in different ways.

Effektiv och underhållssäker lagring av medicinsk data
Creating a database to manage medical data is not the easiest. We create a database to be used for a presentation tool that presents medical data about patients that is stored in the database. We examine which of the three databases, MySQL with relational design, MySQL with EAV design and MongoDB that are best suited for storing medical data. The analysis i performed in two steps. The first step handles the database that is most effective to retriev data. The second step examines how easy it is to change the structure of the various databases. The results show that depending on whether efficiency or maintenance is most important, different databases are the best choise. MySQL with relational design proves to be most effective while MongoDB is the easiest to maintain..

Today's communication solution between the vehicle and trailer is one many see as anon-viable solution, then breakdowns on both the lights and cables are common. Now, anew innovation enters the market, a system that can transmit wireless control signalsbetween the vehicle and trailer.Parvus and Zap, the two solutions that the projekt group has come up with during thisthesis work carried out over the last year on Utvecklingsingenjörsprogrammet.Technologists Peter Jägevall and Christopher Åberg has developed this project on theirown. The group has developed various concepts and chosen to work on, two of them.The project has resulted in this report and a prototypeThe solution that the group has developed is a wireless communication between vehicleand trailer. The project team has developed new power-efficient LED lighting fixtures inorder to implement an internal power source in the trailer. The result of this has becomea maintenance-free and wireless product to trailers.
Utvärdering av fjädrande statorfötter : Nytt koncept i vattenkraftgeneratorer
This thesis is an evaluation of a new design concept for statorfeets in Gallejaur hydro power plant. Founder of the work is Vattenfall AB Vattenkraft. During the 70- and 80´s nuclear power began to be phased in to the Swedish grid, which meant that hydropower became an important source of rules. The generators began running in so called intermittent operations instead of basic operations, which meant 300-600 start/stop per year instead of one-ten numbers start/stop per year. In order to deal with the thermal forces that arise at every start and stop suppliers began to mount so called sliding joints, which is to take advantage of these forces and maintain the stator shape.
Kyrkan som immateriellt kulturarv En studie i kulturvårdens förhållningssätt till liturgiska värden
This master thesis aims to examine the methods of the conservation field and their visionabout maintenance and change, in terms of liturgical values. This is to be able todetermine if there is a need to develop the methods that the field of conservation has tosafeguard the intangible cultural heritage of the churches.This is mainly a literature review, focusing on different tutorials from the Swedish nationalheritage board, and different texts on liturgy aswell as Unesco's Convention for theSafeguarding of intagible Heritage (2003), ratified in Sweden in January 2011. A casestudy of the practical work has been carried out on three churches that have undergonechange. The application process and the results were important for this study.The conclusion is that the conservation field have ambitions to preserve the liturgicalvalues, but they do not have sufficiently developed methods to do so. Nevertheless, itappears that most cases of change in churches, increases the liturgical values..
Molnbaserade affärssystem ? Vad bör leverantören beakta?
Molntjänst är inget nytt begrepp men det är en trend som nu blivit mer aktuell än någonsin. Det har funnits olika typer av lagringstjänster via internet i över tio år men nu har trenden molntjänst blossat upp till att bli högaktuellt inom IT-branschen. För kunden innebär en molntjänst att de köper de funktioner eller tjänster som de har behov av via internet och leverantören hanterar administration och drift. Kunden behöver dessutom inte ha lika mycket hårdvara och programvara internt. Något som är aktuellt nu är att allt fler affärssystemsleverantörer börjar erbjuda sina kunder att lägga affärssystem i molnet.
Developing Dynamic Outsourcing - Bringing continuous added value to the ABB Full Service partnership
Executive summary This master thesis was originally based on a specific assignment given to the authors from ABB Full Service, a unit specializing in providing maintenance outsourcing: ?How can ABB Full Service expand its offering of providing fundamental maintenance by seamlessly incorporating the business concept with competencies and solutions from other ABB divisions?? The academic issue was developed throughout the thesis, resulting in the following formulation: ?From an organizational perspective; how can service providers bring continuous added value to intra-organizational outsourcing partnerships?? Many of the key findings of this thesis are reflected in the issue. The term intra-organizational outsourcing is a proposed addition to the terminology in the academic discourse on outsourcing. The definition of the term is: ? Where an organization outsources a business process interlinked with the physical operations, requiring the service provider to take over a preexisting unit and its employees.This is an accurate description of the form of outsourcing that ABB Full Service is engaged in.
Kulturella problem vid samgåenden och uppköp
Ökande globalisering och minskande inträdesbarriärer har förändrat konkurrensbilden i många branscher. För att stärka sin konkurrenskraft väljer därför många organisationer att införskaffa konkurrensfördelar genom samgåenden och uppköp. Med fördelarna med samgåenden och uppköp följer tyvärr ofta kulturrelaterade problem. Jag har intervjuat anställda på Vattenfall Service Nord (VSN) om ett samgående och två uppköp som VSN utfört för att bilda mig en uppfattning om vilka kulturrelaterade problem som förekommit. Därefter analyserade jag vad som kännetecknar de kulturrelaterade problem och vad som har gjorts och kan göras för att motverka dem.
Effects of ten year old enrichment plantings in a secondary dipterocarp rainforest : a case study of stem and species distribution in Sabah, Malaysia
Large areas of forests in the tropical region have during the last decades been lost and converted to new land uses while other areas have been degraded into secondary forests. These secondary forests need to be restored and rehabilitation through enrichment planting and liberation may help to speed up the recovery process. The objective of this thesis was to evaluate a rehabilitation method that includes enrichment planting, slashing of weeds and girdling of unwanted trees. The site for the project is situated in Sabah, Borneo in a secondary forest which had been logged and burnt by a wildfire. The project?s goal is to rehabilitate and increase biodiversity through enrichment planting of seedlings mainly belonging to the family Dipterocarpeaceae (dipterocarps).
Motorsågskörkortet - en utvärdering av Skogsstyrelsens motorsågsutbildning vid Frossarbo kursgård 2005 - 2007 :
The use of chainsaws in both private forestry and commercial companies is highly associated with personal injuries and accidents with deadly outcome. As a result to this, a driver?s license for chainsaws was presented in the year 2005. To get the license you have to attend a course given by the Swedish Forest Agency or one of several private educators. This study is an evaluation of one course given by the Swedish Forest Agency in Uppsala.
Kvalitetssäkring av servicelämnare för skogsbrukets arbetsmaskiner : Intervjuer och förslag till utveckling
In this study we have examined the possible quality standards and methods for applications with service workshops in the forest industry. The purpose of the methods presented here was to start the work of standarardising the maintenance service in the industry and be of use for service providers in their quality effort.The methods we used to accomplish the study were interviews and field visits together with a comprehensive literature research. Our results are presented in the form of four solution proposals: a standard based on existing SIS standards for terminology and key indicators, checklists that are filled in by mechanics with customer participation, the construction of a instructions database, and the implementation of the method 5s.We believe our suggestions can help the service providers in the four problem areas that we have identified: long term strategy, documentation, recruitment of competent technicians, and standard procedures in their operations. These improvements will be beneficial for both the service provider and the customer..
Testdriven utveckling (TDD) ? En metod för att minska underhållskostnader i mjukvaruprojekt?
The maintenance phase within software projects is typically very expensive in terms of resources. The activities of this phase are largely focused around some form of modification of program code. This leads one to consider if there are alternative methods of code production that results in code that allows for less costly modifications. This thesis has its basis in a subset of those concepts which research has shown to provide more flexible code. Once this subset is established, connections are made between the concepts within the subset and claims of benefits provided by the use of Test Driven Development (TDD) methodology.
