Detta examensarbete är utfört på Saab Training Systems AB i Huskvarna. Saab Training Systems utvecklar, tillverkar och säljer kompletta militära träningssystem.Syftet med arbetet var att minska ledtiderna, då korta leveranstider blir ett allt viktigare konkurrensmedel. Arbetet innebar en kartläggning av nuvarande reserv- och reparationsflöde samt att identifiera problem och komma fram till förbättringsförslag.Vidare har vi studerat reservdelslagrets lagernivå och dess kapitalbindning.Arbetet genomfördes med hjälp av intervjuer med berörd personal, observationer, enkätundersökning samt statistiska studier. Vi har även arbetat med Supply Chain Operations Reference Model som är en öppen referensmodell med vars hjälp man kan kartlägga, förändra och optimera sin verksamhet.Saab Training Systems har som mål att ledtiderna för reservdelsflödet och reparationsflödet skall vara 14 dagar, men i själva verket är det inte så. Dessa ledtider är idag längre, hur långa är dock oklart.De långa ledtiderna beror främst på att i flödena förekommer det mycket passiv tid.

This thesis deals with the goods classification of the Nordic alcoholmonopolies, viz. Alko in Finland, Rúsdrekkasøla Landsins in the FaroeIslands, Systembolaget in Sweden, Vínbúðin in Iceland, andVinmonopolet in Norway. The focus of the study is the web pages of thecompanies (as they appeared April 10th 2011) and the printed pricecatalogue of Alko, from which information on class division has beenexcerpted. The emphasis lies on the division into product groups and theinformation about origin. Within these facets, which partly overlap insome of the classification systems, the principles of division and thehierarchical relations between classes are studied.

Optimizing energy systems is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with an error-free substation of day current technology. To, when possible, lower the return temperature is a way of increasing the effectiveness of the district heating system.This study means to investigate, through simulations and calculations, how big of a reduction in production cost a lower temperature in the city of Ystad?s district heating system would correspond to.

During 2007 the City of Stockholm installed five grid connected photovoltaic systems. The aim of this master thesis is to quantify the amount of produced energy and recommend routines to collect and analyse production data, to make production data accessible by the public and to gain experience for future installations.The total amount of produced energy until March 2009 is 227 000 kWh, with an annual rate of 150 000 kWh. The expected annual rate was 148 000 kWh.All system owners are positive about their plants and see economical benefits in scaling up such systems.The installations need very little attendance and maintenance, however it is recommended that an alarm function is installed for automatic feedback in case of a system failure. All future systems should be inspected during full operation to determine if the actual capacity is matching the installed capacity..

Six different Digital Proofing Systems from three different techniques have been evaluated as totechnique, printing quality, economy and usability. Digital proof from two paper qualities, coatedand uncoated, has been compared with references printed in offset, to see how good they match eachother. Only two Proofing Systems manage to print on reference paper. The other Proofing Systemsuse special paper for digital proof.Measurements and visuell judgement show that the Digital Proofing Systems visualise referencepictures with quite good quality. Proof optimised for coated paper visualise the colours with goodresult.

The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

Background: Postoperative infections are a serious patient safety problem and affects about 3 % of all patients undergoing surgery. The consequences are prolonged hospital stays, high social costs, increased use of antibiotics and impaired quality of life for the patient. It has been shown that postoperative infections may be caused by contamination already in the operating room. Today we know that there is growth of microorganisms on the instrument table´s top, but there is a research gap about the instrument table's edges.Aim: To examine if the sterile drape on the instrument table´s edges are sterile after finished surgery.Method: Contact plates are printed on strategically selected areas on the sterile drapes top and edges. In the pilot study, a total of 51 cultures were taken at the end of three operations which lasted over three hours.Results: Growth on the top surface and the edges of the sterile drape were detected.

The collection of hazardous waste from the household around Swedish municipalities varies. 1% of the households waste is hazardous waste. It has hazardous features that can give bad consequences for the nature and human health if we don?t collect it and treat it. Therefore the law controls it, the municipalities have responsibility for the household waste.

Today the individual ventilated cage system (IVC-system) is a commonly used housing system for mice in research facilities. IVC systems have HEPA- filters and are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare of breeding females and pups of two different strains of laboratory mice (NMRI nude mice and C57BL/6N) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. The NMRI nude (Nu) females gave birth to 18 litters in Allentown, 16 litters in Arrowmight and 15 litters in Tecniplast.

This qualitative case study, made with four companies, looks closer at how more effective information management, with the help of IT-systems, affect companies market communication and relations to customers and suppliers. Customer Relationship Management perspective is used and Enterprise Resource Planning-systems are the ground for new technology change. The main conclusions are that new technology affects the outcome of companies? relationships towards their customers and suppliers and that the processes and activities between the involved parties are more closely linked. Also involving your suppliers and external actors makes the information handling more effective and companies that do so most likely have a competitive advantage..

 This paper covers how a company must act to become ?greener? and yet still increase profitability with the main emphasis on the inner structure of the company. The research is focused on the Swedish security systems company Niscayah AB, part of the multinational corporation Niscayah Group with approximately 6000 employees. A company can be assumed to consist of seven parts (strategy, systems, structure, super-ordinate goals, staff, skills and style) that have to cooperate for the firm to be able to become more environmentally friendly. Also, the economic performance is of importance and therefore that too is examined.

The EU has decided that it should be possible for consumers to get information about the origin of the electricity they buy. Therefore, there is a need to examine different systems for electricity disclosure. In this thesis two ways of disclosure have been studied:? Certificate system. A certificate system involves two parallel markets, one for trading electrical energy and one for trading certificates of origin.? Separated Markets.
