Modellbaserad systemutveckling i komplexa verksamheter. En fallstudie av Coremetoden

In system development it is today increasingly common to use a model-based system development method. These methods that are suited for Agile work with simple and quick updates and implementations of new applications in systems conform to the requirements that are becoming more important today, namely more flexible and less expensive system that still maintain high quality and safety.A company that has been working with this type of system development method for a long time is Genicore AB, which also has developed their own tools and model language in order to better model the information management systems in complex and abstract operations. Genicore AB is trying to spread their method other developers and have therefore taken the initiative to start this study. The method is evaluated and tested by two students with relatively little experience in model-based systems engineering in order to gain a new perspective on how the method functions. The method has been applied to an educational activity in order to test it in a new domain, and this led us to our research question;?What criteria are of particular relevance in the implementation of a MBSD method on on complex businesses??Through literature reviews and interviews, we formed an idea of how model-based system development works from a theoretical perspective, and then continued to the case study conducted on the educational activities at the faculty of IT at University of Gothenburg.

Samhällsplanering i Sverige under 50 år : -en genomgång av tidskriften PLAN

In 1989 the United States choose, after years of conflict, to carry out a military intervention in Panama, to remove Manuel Noriega, convicted for drug dealing and for threatening the lives of the Americans living in Panama. The aim of this study is to examine whether George H. W Bush?s arguments for the military intervention comply with the principles of the just war.The method chosen for this study is a qualitative literature study, based primarily on secondary data. It is a case study with two complementing theories, the theory of the just war and the world system theory.The result showed that the American intervention both can be justified and unjustified following the principles of the Just War Theory.

Uppgradering förarstol SEP: på uppdrag av BAE Systems
Hägglunds AB

En prototyp till en förarstol för det militära fordonet SEP har tagits fram av tidigare anställda på BAE Systems Hägglunds AB i Örnsköldsvik. Stolen måste uppfylla en omfattande mängd krav då den är tänkt att användas i ett stridsfordon, och av personer av varierande storlek. Den nuvarande prototypen för stolen anses dock vara för dyr och det har dessutom framkommit en del klagomål på konstruktionen. Stolen måste därför göras om så den blir både billigare och bättre. Genom att ta del av tidigare genomförda tester på BAE Systems, samt genom att göra nya tester upptäcktes det dels vad som var dåligt och därmed behövde göras om, och dels vad som var bra och kunde tänkas behållas.

Räntabilitet och kapitalstruktur i svenska börsbolag: En analys av utvecklingen från 1990 till 2004

The aim of this thesis is to describe the development of profitability and capital structure in Swedish quoted companies during the period of 1990 to 2004. Further, the aim is to determine the relationship between profitability and leverage in order to conclude whether the choice of capital structure supports the pecking order theory or the trade-off theory of capital structure. The findings show that return on assets fluctuates between 3 and 11 percent and that return on equity fluctuates between 3 and 22 percent during the period. Further, the leverage and the cost of debt have decreased. This indicates lowered financial risk in Swedish quoted companies in the period between 1990 and 2004.

Marknadsföring av akademiska bibliotek - en jämförande studie mellan Sverige och England

This thesis conducts a comparative study between two academiclibraries, one Swedish and one English, in order to analyse ifdifferent funding systems influence the marketing of theirservices. The theoretic foundation is built on relationshipmarketing, which emphasises the importance of creating andmaintaining relationships. A qualitative approach has been usedthrough the use of case studies, with semi-structured interviewsbeing held with library staff and managers in both countries. Inaddition to these interviews strategic plans have also beenanalysed. The result from the study shows that whilst there aresome differences between the two university libraries there arealso similarities, which indicates that it is not clear if differentfunding systems have an impact on the marketing of the services..

Respondentgruppers inställning till IASBs förslag om förbud mot återföring av tidigare nedskriven goodwill

The purpose of this paper is to examine whether there is a difference between the respondent groups preparers and non-preparers position in IASBs question if a reversal of previously impaired goodwill should be prohibited. The background is an exposure draft sent out by the IASB and we examine the answers, in form of comment letters, sent in by the respondents to reach our purpose. Our method is positivistic in the sense that we study already existing theories when we create our hypothesis which gives our assumption about how the result of the respondent?s answers will be. Our data, which we have collected from the comment letters, is qualitative secondary data.

Bemötas som individ : En kvalitativ studie ur användarperspektiv av BUS-bibliotekets verksamhet

The purpose of this thesis is to investigate the library for children and young people at Sahlgrenska university hospital in Sweden from a salutogenic perspective. The sociologist Aaron Antonovsky states that human health is benefited by the salutogenic perspective, since it stimulates our sense ofcoherence.The theoretical departure point is sense-making theory. The theory states that in order to move through life, humans are dependent on a sensemaking process. To make sense of our current situation, we need information. What kind of information depends on the individual and its context.

En jämförelse av Sveriges och Storbritanniens producentansvar för förpackningar :

The purpose of the thesis is to compare Sweden's and Great Britain's total costs for their systems regulating producer responsibility for waste packages. Producer resonsibility is a strategy implying that producers are responsible for their waste also after its use. Sweden and Great Britain introduced different systems systems after an EU directive was adopted in 1994 (94/62/EC), and they have resulted in entirely different recycling levels in the two countries. In the Swedish system, responsibility has been delegated to the industry who are responsible for reaching the determined goals. The economic instrument used is a fee, set and managed by the industry. The British system is more centrilised, and the economic instrument used to finance recycling of waste is a system based on transferable permits. The thesis compares the four different alternatives: delegated and centralised methods, and fees and transferable permits analytically.

Energisäkerheten för fjärrvärmeanläggningars bränsletillförsel i Mälardalsområdet

There are several energy systems in the Swedish society and to ensure the comfort and health of the citizens it is of importance that the different energy systems are functioning properly. District heating is one of these energy systems and many household depend only on district heating to warm up their homes. District heating is dependent on several processes where every step needs to function in order to deliver the produced heat to the end consumer. Previous studies have investigated the distribution of district heating and how to make customers choose district heating as their heating method. The supply of fuel to the district heating plant has not been studied as much, even though it is an important part of the whole system. This thesis is a part of the project NORD-STAR (Nordic Strategic Adaption Research), which has focused on climate adaption in the Nordic countries.

Effektivisering av logistiklösningar : En jämförelse av nya och gamla logistiksystem vid ROT-projekt

A persistent problem in the construction industry is its low margins of profit. It is often difficult to earn money due to low efficiency and high costs. Logistics on the construction site answers for a large amount of these costs and it is therefore of interest to find new, more efficient logistic solutions. The purpose of this thesis is to compare two different logistic systems and further to evaluate which one that is the most efficient and profitable. A comparison is made between the traditional logistic systems used for years and a new logistic system developed by an industry association called BEAst.

Våld i parrelationer : en teoretisk analys

The purpose of this study was to do a narrative survey of the discussion about violence in partner relationships that is held in research literature. The question at issue was: How do research literature discuss violence in partner relationships, with focus on heterosexual relationships? The eight primary documents that have been chosen are written by researchers, professional therapists, National Counsil for Women's protection (Nationellt Råd för Kvinnofrid, NRK) and Swedish Government Official Report (Statens Offentliga Utredningar, SOU). To investigate the theories, discover the similarities and differences between them and how they can complement each other, the documents statements has been analyzed with a dialectic-hermeneutic approach and social constructionism and discourse theory.The research findings showed that the gender perspective theory, the psychodynamic theory and the social psychology theory have a few things in common, but that they on the whole are different and contradict each other. The gender perspective theory dominates the discussion but needs to be combined with the other theories to give a more all-embracing understanding.

Revisorsyrket i förändring

Changes in the society engender changes in the practice of the auditor profession. Stricter laws, more detailed recommendations, and demands from the auditor?s clients have increased. The auditor constitutes a profession and therefore it is important that there is a trust since the auditor is the one that certifies the quality of the company?s economical information.

Standardisering av kommunikation och styrning av leverantörer inom Build-to-Print vid BAE Systems

Idag arbetar avdelningen för extern produktion vid BAE Systems Hägglunds med produktions stödjande uppgifter för leverantörer av Build-to-Print komponenter. En allt större del av BAE Systems produkter konstrueras av BAE Systems konstruktörer medan tillverkning genomförs av leverantörer. Denna förändring har skapat ett behov för BAE Systems att kunna stödja leverantörer i produktionsprocessen för att förhindra att kvalitetproblem uppstår. Den produktionsstödjande uppgiften blir också viktig då det finns en vilja på BAE Systems att kunna genomföra kvalitetssäkring hos leverantörer innan ankomst. Dagens arbetsprocess för produktionsstöd har vuxit efter olika leverantörers tillfälliga behov vilket har gjort att inget standardiserat arbets- eller kommunikationssätt finns.

Konstruktion av småsäckstömmare

Scania CV is one of the world's largest truck manufacturer. It is not only the directproduction of vehicles and methods that are important for Scania but also the servicemarket handling spare parts, repairs and workshops. The department Vehicle ServiceInformation construct standard times through work measurement for particularworks in the workshops. The software application STAM is used in the servicemarket to create and store standard times which then are exported to theworkshops' own systems.The purpose of this master thesis is to analyse and evaluate the internal workmeasurement system that includes standard times and the software STAM. Also,based on external analysis and benchmarking of other systems suggest appropriatefuture development within the area for Scania Vehicle Service Information.In order to perform the investigation, interviews and studies have been doneinternally at the departments that are involved in work measurement as well asexternally at Scania workshops.

Riktlinjer för studier av icke-existerande komplexa sociotekniska system : Erfarenheter från en studie av införandet av ombordbaserad helikopter på korvett av Visbyklass

This report consists of a discussion about suitable methods for studying complex sociotechnical systems that are still being developed. There are large economical advantages with studying new systems before they are completely developed since problems can be discovered early and thereby avoided. It is, however, difficult to study developing systems, there are methodological limitations. These limitations are discussed and recommendations for studying non-existing complex sociotechnical systems are presented.The report is based on experiences from a study of the introduction of a shipboard helicopter on the corvettes that the Swedish Armed Forces are developing. A shipboard helicopter implies high requirements on the hosting ship.
