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.

A totally mixed ration (TMR) is a mixture of all the necessary feed components for the cow. She will eat the exact same feed in every bite which will make the rumen pH more stable and always supply her with a constant proportion between roughage and concentrate. This will make it possible for the cow to eat more dry matter (DM) a day because the fibre requirements are fulfilled. If a part of the concentrate is given separated from the mixture it is called partly mixed rations (PMR) and is almost always used when using an automatic milking system (AMS). When using TMR and PMR it is important to have a high hygiene, be accurate when mixing the feed and to look after cows in a good and strict way. The aim of this study was to document different farms with PMR in an AMS to see which routines they have and how they are managing their production.

 This study was conducted in autumn 2008 on the Company AB, which is currently in a growth phase. The company manufactures hydraulic systems for the heavy vehicle industry and has annual sales of approximately 250 MSEK with 165 employees.The rapid growth and unchanged planning is the starting point for this report. It all began in 2005 when the company received an unusually large order. During this period, the first priority was to satisfy customers and all other focus was disregarded. This has primarily resulted in a messy production and long throughput times.

The objective of this study was to make an inventory and a potential analysis of the organic beef production in the region of Gävleborg, Sweden. A survey was conducted, where a questionaire was sent to all farmers in the region who had environmental subsidies concerning organic cropping systems in 2001. In total, there were 701 farmers, of which 46 % participated in the study. Three slaughter houses were interviewed to get their pictures of the development of organic beef production. The study shows that there are potentials and interests in the region to increase the production of organic beef.

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

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.

TitelGränslös kommunikation Kommunikationen i ett globalt företag under förändringFörfattareÅsa BorgKursExamensarbete i Medie- och kommunikationsvetenskap avancerad nivåHandledareAnnika BergströmTerminVT 2011SyfteAtt undersöka hur kommunikationen fungerat i ett globalt företag under förändring.Metod och materialKvantitativ enkätundersökning på ett totalurval av 138 mellanchefer på Volvo Business Services. 83 personer svarade vilket gav en svarsfrekvens på 60 procentHuvudresultatMed hjälp av en webbenkät har jag undersökt hur kommunikationen fungerat i det globala företaget Volvo Business Services under en förändring. Resultaten visade att en stor del av mellancheferna i företaget ansåg att informationen varit tillräcklig men att en betydande del ändå inte var nöjd med kommunikationen som gått ut. De upplevde då svårigheter att svara på frågor från anställda. Det visade sig även att mellancheferna föredrog att få informationen genom andra kanaler än de kanaler de fick.

The aim of this study was to investigate how the process of implementing a quality management system for food safety was handled in four different food producing companies in Sweden. The aim was also to analyze what difficulties the companies face and the possibilities that arise when certified. Furthermore, the reason for implementation was discussed as well as the main expectations on the certificate. Implementing a quality management system is a good way of ensuring the quality and hygiene of the food production and it also increases the traceability of food products through the whole food chain. A food safety standard provides a method of preventing problems and crisis and it can also help to handle requirements from authorities, the market and others.

Reporting harvested and forwarded volumes are important for the forest industry as it provides information of the size of the stock and facilitates logistics. Figures from Holmen Skog show low reporting frequency. The purpose of this study is to investigate the reason and find suggestions for improvement. A total of 17 machine operators were interviewed using a questionnaire combined with open questions. The results show that the majority of the machine operators find it simple to use the reporting system, although, some of them reports that it doesn?t always work as supposed to.

Habituation to an automatic milking system (AMS) for cows in their first lactation differs from habituation to other milking systems. In AMS the cows are supposed to visit the milking station (MS) voluntarily. The milking takes place individually during the whole day, except when the milking system is cleaned. Milking is carried out without any human survey. The aim of the study was to describe the cow?s introduction in AMS in their first lactation.

För att vidareutveckla Volvo Aeros konkurrenskraft för stora fläktstrukturer undersöks nu möjligheten att integrera fläktutloppsledskenornas aerodynamiska och akustiska funktion med den lastöverförande funktion som konventionella mellanhus har. Som en del i detta vill nu Volvo Aero kunna skapa en första konstruktionsmodell, i ett tidigt konceptstadie, som har en låg vikt men som ändå uppfyller styvhetskraven som ställs på konstruktionen. Denna rapport avhandlar en optimeringsrutin för optimering av bypass-delen av mellanhuset i en jetmotor. Optimeringsrutinen är anpassad för Ansys och i de optimeringar som genomförts så har två av Ansys inbyggda optimeringsalgoritmer använts. Resultatet av användandet av dessa algoritmer visade att om man vill ha med modalkravet i analysen så måste man ha en god startkonstruktion för att optimeringen skall finna den bästa lösningen..
