Intresset för sömlösa stålrör med stora ytterdiametrar i förhållande till tunna väggtjocklekar har ökat tillsammans med att högre hållfasthet i olika stålsorter tillkommit. Detta gör det möjligt att tillverka lättare, billigare och mer materialeffektiva stålprodukter med samma eller högre hållfasthet som tidigare.Denna nya utvecklingsriktning medför förändringar och utmaningar i en av företaget Ovakos produktionslinor i Rörverk 5 Hofors, vilket de har behov av att samarbeta med maskinkonstruktionsföretaget BEKAB för att utvärdera och utveckla.I Ovakos produktionslina i Rörverk 5 finns en del av ett asselvalsverk som kallas för "förreducerare". Denna del av asselvalsverket ser Ovako ett stort intresse i att utvärdera och utveckla för att bättre anpassas till den nya utvecklingsriktningen.  En känd utmaning hos förreduceraren sen tidigare är att den från början är framtagen för att reducera ner ett kvalitetsproblem hos rörprodukterna som kallas för trattbildning. Projektet fördjupar sig därför inom trattbildning för att bättre förstå grunden till förreducerarens nuvarande design för att därefter genomföra en redesign av förreduceraren.I en nulägesanalys av nuvarande förreducerare framkommer ett flertal olika produktionsutrustningsproblem med tillhörande kvalitetsproblem hos rörprodukterna. Projektet väljer därmed att fokusera på de produktionsutrustningsproblem som ger störst effekt för förreduceraren om de löstes.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

Recent developments suggest that private and public companies are moving towards a more service-oriented business. Service orientation means that hardware is often sold in packages with service agreements, which makes the investment more difficult to assess. The challenges that arise will be to assess the value of the overall package, the information needed to make informed decisions and the operational requirements in combination of hardware, software, support agreements, training and more. The paper therefore aims to examine how decision makers can evaluate the benefits of these investments and obtain a stronger base to make better decisions. There is within the area of radiology in the region of Västra Götaland a pronounced need for a better flow of information regarding medical equipment and related service agreements.

In 2009 The National Land Survey of Sweden, Lantmäteriet, commenced a project intended to provide a new digital elevation model (DEM) of Sweden. The method chosen for the project was airborne laser scanning (ALS). In addition to information about the land surface the project will also provide information about the forest, this as a by-product. This data can be used to estimate forest variables such as height and volume. The estimates are often more reliable than what is standard today. This study is based on interviews with employees and members of the forest owner association Södra in southern Sweden.

Usually it is in the description of what is to be acquired as the information is incomplete, but also in knowing when Quality Control-functions (QC) is supposed to be used.The aim of this work is to describe and analyse the material acquisition process.

TitelEn kvalitativ fallstudie om hur företag förhåller sig till gapet mellan den operativa och den strategiska delen av LeanNivåKandidatuppsats FörfattareIgor Jovanovi? och Linnea Juhlin HandledareStig Sörling och Tomas Källquist DatumMaj 2014 ProblemTidigare forskning har påvisat att det finns ett gap i företagens användning av styrverktyget, där företagen i stor utsträckning förbiser vikten av den strategiska delen av Lean. Detta har gjort att företag har haft svårigheter att uppnå sina mål med användandet av styrverktyget. SyfteSyftet är att skapa förståelse för hur tillverkande företag förhåller sig till gapet mellan den operativa och den strategiska delen av Lean, samt belysa de beståndsdelar gapet består av. MetodStudien har antagit ett hermeneutiskt och socialkonstruktivistiskt perspektiv där tematisering och ett deduktivt tillvägagångssätt har använts. Studien har genom kvalitativ metod med fallstudiedesign studerat fyra stora företag med hjälp av semistrukturerade intervjuer. TeoriEn genomgång av Lean-konceptet görs för att skapa förståelse för styrverktyget sedan fördjupar vi oss på den strategiska delen av Lean för att kartlägga de olika beståndsdelarna som kan överbrygga gapet. BidragGapet framträder inte lika tydligt i vår studie, fallföretagen har i sitt tankesätt störst fokus på den strategiska delen av Lean. Kultur och ledarskap är huvudbeståndsdelar i jobbet med att överbrygga gapet där den strategiska delen ämnar skapa positiv energi hos medarbetarna.

In the last decades, high speed cutting has become an attractive technology in the wood industry. The possibility of reducing global costs in addiction with an increase in productivity, were the main reasons for the enlargement of the use of this technology. As usual, these advantages are accompanied by disadvantages that should be carefully analyzed. If on the one hand cutting forces are reduced with increasing cutting speeds, on the other hand, the centrifugal forces affecting the tool are higher. Exposed to such high loads, there is a considerable risk of tool failure that embeds hazards for both machine and workers.

To create a profitable and competitive business an important factor today is a well-functioning logistics. Through effective internal material flows effective logistics can be achieved. Unnecessary handling and movement of materials is a waste which affects the internal material flow. These wastes should be identified and eliminated as much as possible to improve the internal materials handling and through that achieve a more efficient business. At Fagerhults Belysning AB, where professional lighting systems are developed, manufactured and marketed, a new inventory has been built and changes in the assembly has been made during the past year.

The purpose of this study is to examine the usage of IT technology within preschool and study how IT tools are used by preschool staff for administrative as well as pedagogical assignments. Several aspects affects the work preschool staff do with IT which concerns availability to technology, how technology is used and how technology is made available for the children. There are a number of questions linked to these aspects where some examples this study examines are which advantages, disadvantages, obstacles or other limitations that comes with introducing IT? This study also examines how, when and in what contexts IT is being used? Other questions examined are the pedagogue?s general views of IT, competence development and eventual needs of investment? Further on this study examines to some part how children interact with IT during pedagogical activities? The overall objective is to shed light on problems that preschool staff encounter  in their daily work and on the basis of identifying important questions at issue that could constitute a basis for further research. The results of this study are based on both a literature review and a field study.

The examination has been performed at Bjerking AB, which is an architectural and engineering company. Bjerking AB has the ambition to be a member of Green Building.The Green Building program developed in year 2005 by The European Commission, the program is an environmental system with the aim to improving energy efficiency within the sectors of non-residential buildings. The minimum requirements to participate the program are following: in new-built buildings the calculated energy consumption must be 25 % lower than the requirements in the BBR (Building regulations) and in refurbishment the reduction must be 25 % lower than before the optimization.The aim of this study has been to examine and review the company Bjerking AB's energy efficiency work in the project of building the school/kindergarten S:ta Maria Alsike, where the goal is to get this building Green Building classed. A description of requirements to become a member of the Green Building has also accomplished in the thesis.The methods performed in this study are literature review, searches on the Internet, studies on the project database for facts/values, calculation of energy consumption and interviews of members of the Green Building. The following issues have been dealt with in the report;-          Did the building in the project manage the requirement to achieve an   energy consumption that is 25% lower than the requirements in BBR?-          What technical measures/system was selected in the building?-          What kind of cooperation was the project based on?-          What is required for consultancy companies and real estate owners to become members of the Green Building?The study of the project and calculation of estimated energy consumption in the building, give the result 47 kWh/m2, year.

The price of Swedish forest properties has gone up by 77 percent during the past five years. Amongst private forest managers the high price level signals optimism and confidence for the future. Many forest owners manage large capital in the forest and a planned economy is to a larger extent demanded to achieve a positive economic result. Forest is long-term and to maximize a single year without planning for the years to come results in less optimization of the parameters available to achieve a favourable economic result. This case study investigates the investment of two forest properties situated in Götaland. The management of the forest has been planned for both properties during a period of ten years.

Det är allt vanligare inom tredjepartslogistik att kunder hyr en yta för lagring. För den uthyrande parten, i detta fall Delta Terminal, är arean den begränsande faktorn för hur stor yta som kan hyras ut. Idag använ-der sig Delta Terminal av beslutsunderlag i form av lokalernas area och erfarenhet vart gods ska placeras och har inget hjälpmedel för att beräkna vart och hur mycket gods som kan allokeras för att använda så liten yta som möjligt. Studiens syfte har därför varit att ta fram ett faktabaserat hjälpmedel som kan användas som beslutsunderlag. För att uppnå syftet har en matematisk modell utvecklats för att optimera hur gods kan placeras till olika lokaler för att använda så liten area som möjligt och även kunna simulera förändringar.

The Swedish agricultural sector is currently experiencing substantial structural changes, where the number of agricultural enterprises continuously decreases and the average farm size increases. In order to maintain competitiveness, it is important to be aware and adapt to changes concerning the surroundings of the company (Johnson et al., 2011). Agricultural commodity prices sharply fluctuate on the global market in recent years, affecting the profitability of farmers. High volatility market requires tools to reduce price variations and increases the need of decision-making (Bouder & Beth, 2003). Farm-based grain handling facilities increases the sale options regarding agricultural commodities; a flexible strategy to get additional compensation for the storing the grain produced on the farm (Edling, 2002; Edwards, 2013).
