The production costs have steadily increased within the construction industry during the 21st century. Voices are raised meaning that the construction industry is too unsuccessful in making the production more efficient and to develop it?s way of working. One way to deal with the production costs is to minimise the waste, with waste meaning activities that doesn?t add value to the finished product.

This thesis aims to examine the viability of various techniques for increased electricity generation in CHP plants and the effect of electricity price fluctuations on the profitability.The techniques examined are fuel dryer, pellet production, methane production, combined methane- and pellet production, seasonal heating storages in caverns and pit heat storages and condensing tail. Using Excel and Matlab, the prerequisites for investment costs, revenues and expenses were calculated.What affects the price of electricity is a combination of economic and technological development, energy prices, economic structure, population changes and weather. Different scenarios for the electricity price were therefore examined. In the base case, the electricity price was given by the Nord Pool electricity price statistics of area three in 2011. Thereafter, WiMo was used to design the electricity scenarios for 2030, which was then applied to the data to obtain the viability of various scenarios. The techniques examined were found to give greater profits to the CHP plant by increasing and optimizing the production of electricity.

The aim of this study was to examine the readability of news articles published in the Swedish national newspaper Dagens Nyheter during the years 1999 - 2013. Our hypothesis was that the written language in newspapers is simpler today than it was 15 years ago. To measure the possible change of the written language in a quantitative study we chose to use a method to calculate the readability of 30 news articles, two from each year. We could not see any development of the language level so we chose to do a complementary qualitative study of the layout and presentation of the news articles. This secondary study showed a significant change in how news is presented throughout the years.

The aim of this thesis is to investigate if an automation of the manual packaging process at Legosan AB is profitable. Legosan AB, located in Kumla, performs subcontract work of dietary supplements and medical products to companies within Europe. The chapterportal robot is used in the other. As there are several options in the choice of packaging robot the suggestions of improvement are divided into two different designs. Other machines and equipment necessary for the different suggestions of improvement are showed and their measurements are presented.

Examensarbetet är utfört på Volvo Construction Equipment Components AB i Eskilstuna. Där tillverkas transmissioner och axlar till hjullastare och ramstyrda dumprar. Uppgiften har varit att ge förslag på en layout med bästa potentiella monteringsupplägg på transmissionsmonteringen, baserat på prognostiserad volym år 2006. Stationsmontering är det rådande produktionsupplägget. Det faktum att monteringstiden är lång och att det förekommer dolt montage gör det lätt att glömma detaljer.

In the dairy production it is necessary to be able to sort cows. Dairy cows are sorted for many different reasons i.e. regrouping into production strings or for treatments i.e. inseminations, pregnancy and health checks, vaccinations or hoof trimmings. One labour saving way of conducting sorting is by using an automatic sort gate.

Water is an essential factor for both people and animals, and access to water is therefore of great importance. The water access also largely determines the availability of food for people and feed for animals. The aim of this study was to survey the affect of water access on milk production from dairy animals. The study included nineteen farm visits that were made in the Nyando district in Kenya between February and Mars 2011. Farm visits included interviews with questions about for example number of dairy animals, milk production, water access, feed and water routines.

This examination work is performed at the institution of industrial economy and production at Jonkoping technical university, for JELD-WEN Door Solutions plant in Forserum.Today the focus in the company is on to reduce their inventories binding of capitals as well as inventory of products and that includes to get a good control of the supply and handling of material which is of great importance.JELD-WEN Door Solutions is one of the worlds leading producers of windows and doors and the head-office is located in Oregon, USA.A great number of wooden doors are manufactured by the company in varying of constructions, classifications and performance.The production of the plant in Forserum has a project- and customer focus manufacturing where only internal doors are produced. The overall market they are concentrated on is to different institution such as schools, hospitals etc.The purpose of this work is to investigate possibilities to improvement of material- and production control at JELD-WEN. The report will handle the master production schedule to and from the production divisions within manufacturing industry. Focus will be on the way for information- and material flows from arrival, transport within the company and further on to customers.Further a map of the flow was performed which gave a clearer picture of the connection between the flow of information- and material for the manufacturing process. On the basis of the mapping of the flow, the group discovered that the flow of material had some improvement potential.

This study was conducted at Glimek AB, a company that has chosen to decentralize its central storage unit in order to increase production efficiencies. The purpose of the study was to identify the problems in the production cycle that lead to the decision to decentralize the central storage unit, as well as identifying what the decentralization entails. The effects of the decentralization have not been analyzed in the study, and consequently neither financial nor production disadvantages have been considered.Appropriate questions were formulated based on the chosen underlying theories, and were asked to selected individuals with relevant knowledge. The study is based on the information that was gathered from interviews with management as well as staff within the company. In addition, supporting information such as flowcharts, drawings, orders and decision support documents were supplied by the company.

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.

ASSA AB har först infört verktygen 5S och standardiserat arbetssätt, vilket möjliggjort införandet av andra verktyg såsom kanban. Inget av detta hade dock varit möjligt med ett lyckat resultat om inte personalen först blivit utbildade och en leankultur skapats.

There is a common belief that the arts contain knowledge of creativity that can enrich the business world. Similarly, the arts are in need of additional support from the private sector and know-how of business practices. In short, there is a need for mutual understanding. With my background as a dancer paired with my studies at the Stockholm School of Economics I have taken the challenge of bringing the two worlds closer together. By changing a social system, like an organization, it is possible to get a better understanding of it.

This paper aims to determine what is decisive for localisation of production units when a company engages in offshoring. By performing a case study on Electrolux and comparing the results with theoretical literature we discuss the implications for manufacturing companies in general. To facilitate a structured analysis we have developed a model dividing the localisation decision into five perspectives and four geographical levels. We have found that the determinants of localisation vary depending on the geographical level of the decision process. Since all geographical levels are interconnected, the analysis needed for a decision on all levels simultaneously is very comprehensive.

Detta examensarbete är utfört mot Sandvik Mining and Construction (SMC), på en produktionsenhet i Köping. SMC Köping, som tillverkar och levererar olika typer av gruvborrar till kunder över hela världen, har under en tid upplevt att deras lagerhantering inte fungerar optimalt med en osäkerhet kring lagersaldo och problem med att lokalisera artiklar. Ett väl fungerande arbetssätt på lagret är kritiskt för den interna och externa leveranssäkerheten, något som direkt påverkar företagets möjlighet till att konkurrera. Syftet med detta examensarbete är att genom en kartläggning av nuvarande lagerhantering vid SMC Köping analysera, utveckla och implementera förbättringsförslag för layout och hanteringen vid det befintliga lagret på ett sådant sätt att det säkerställer ett materialflöde till, i och ifrån lagret, med förbättrade interna och externa leveranser som resultat. För att göra examensarbetets syfte mer överskådligt och uppnåeligt har ett antal delmål formulerats, enligt följande: - Beskriva, för denna studie, relevant teori kring layout, arbetssätt och systemstöd för att författarna ska få en bild över hur detta behandlas i litteraturen.
