ALM - Tillgång/skuldmodell för riskberäkning och portföljoptimering

Asset management in insurance companies differs from conventional asset management to the extent that respect has to be taken to both assets and the commitments the insurance company has towards its customers. A model that has proven to fit well regarding the matching of assets and liabilities is the Asset Liability Management Model (ALM model). In addition to the matching in the balance sheet, the ALM model can be used in a company's work with strategic portfolio allocation by applying it as a basis for analyzing investment strategies with expected risk and return. From this, the ALM model also becomes relevant for calculating key figures according to the legal framework Solvens II which includes laws and regulations regarding the demands on economical strength (solvens) of insurance companies.Hence, the goal of this masters thesis has been to, on behalf of Bliwa Livförsäkring, create an ALM model to support the asset management department of Bliwa in their work with defining a credible way of analyzing the future risk and return of Bliwa's asset portfolio and insurance undertakings.The ALM model generally consist of four submodels, the scenario model, the liability model, the asset model and the company model, where the scenario model often is named as the core of the ALM model. The course of action has been to develop these submodels individually, with focus on the scenario model.

Optimering av reducerad bearbetning : högre skörd till lägre kostnad

Optimization of soil tillage and crop rotation is important in many aspects, but particularly in maximizing profit margins. Since the economic outcome is usually decisive, it can be interesting to study different combinations of soil tillage systems and crop rotations in order to identify the maximum economic outcome. How a crop functions in a particular tillage system determines whether it is profitable to grow that crop. Different tillage systems affect the soil and its processes in different ways. Reduced tillage often works best on weak-structured heavy clays and on silty clays.

Multikriterieanalys av potentiella konflikter vid markanvändningsplanering - Naturstenbrytning i Lysekils kommun

The purpose of the essay Multi criteria analysis of potential conflicts concerning land use planning - natural stone mining in Lysekil municipal is to study possibilities and limitations in GIS based multi criteria analysis as a tool for land use planning. How GIS based multi criteria analysis can be implemented to localize potential conflict areas between natural stone mining and other land use activities and what advantages and disadvantages the method holds are the main issues of this study. The essay studies these questions through a case study, concerning the geographical area of Lysekil municipal in western Sweden and problematizes the interest of natural stone mining in relation to other land use interests. A literature study was carried through, concerning multi criteria analysis and planning. After collecting and processing of data the multi criteria analysis could be implemented in the ArcGIS tool Weighted Sum.

Optimering av den kemiska reningen vid Fläskebo deponi

Landfill leachate contains a variety of contaminants and is created when rainwater percolates the landfill. For landfill management the leachate is the main issue that can cause problems to the environment. At the landfill of Fläskebo, Renova AB treats the leachate in a local treatment plant. The treatment consists of a chemical treatment step with chemical precipitation, flocculation, sedimentation and filtration, and a final step with a carbon and peat filter. Renova has to ensure that the condition of the leachate reaches the regulation set for the landfill before it is released to the recipient.

Motviktsslungans dynamik : En analys av medeltida konstruktionsråd för mekaniskt artilleri

 AbstractThis Master?s thesis analyses the dynamics of the medieval counterweight lever engine, ortrebuchet, a type of mechanical artillery. The purpose is to study the differences between different types of these machines, and see if computer simulations can be used to validate preserved advice on construction. Simulations include machines with a fixed counterweight, a hinged counterweight and a combination of both counterweights.Due to the almost complete lack of archaeological finds and insufficient historical source material there are still, after more than a century of research, many unanswered questions concerning the design and performance of these machines.The present study is based on an analysis by Jahsman (2004). A more detailed mathematical model employing Coulomb-friction is used.

Logistik i små företag - En analys av problem och möjligheter för STARKA

In order to suggest improvements for the logistics of STARKA, we felt that we had to analyze all the activities which were related to STARKA's logistic processes. Our primary analysis consisted of a rough but comprehensive description of different functions in the company, and the relationship between them. This was performed by following a typical order through the company to see which functions were affected by the order.Since we needed a more thorough view of the company, we decided to analyze the different products STARKA currently has on the market, focusing on economic data such as turn-over, profit, profit margin, deficiency cost and cost of warehousing. We also analyzed the company's choice of manufacturing processes, organization, warehousing processes, strengths and weaknesses.These analyses gave us a clear understanding of the company and its processes. STARKA is a small, function oriented company with a wide range of products.

En analysmetod för att optimera skotning mot minimerad körsträcka och minimerad påverkan på mark och vatten

Teknikutvecklingen i skogsbruket har under senare år avstannat och det finns en stor förväntan på nästa ?tekniksprång?. Samtidigt är debatten om skador på mark och vatten i skogsbruket högaktuell. Denna rapport behandlar möjligheten att kunna öka effektiviteten i skogsbruket samtidigt som hänsyn tas till mark och vatten. Genom att använda flygburen laserskanning (LiDAR) och digitala terrängmodeller (DTM) har analyser över vattenflöden kombinerats med optimeringar av skotarens körvägar. Kombinationen ger möjlighet att planera ett optimalt skotningsarbete för en slutavverkning utefter vart på trakten vatten potentiellt kan finnas och även vart på trakten virkesvolymen finns.

Syns du finns du? : En studie över användningen av SEO, PPC och sociala medier som strategiska kommunikationsverktyg i svenska företag

Syftet med arbetet var att undersöka hur lärare och elever interagerar med varandra och hur det naturvetenskapliga innehållet presenteras och kommuniceras under en naturvetenskaplig lektion på gymnasiet. Studien ingår i det nordiska forskningsprojektet Explora som arbetar med naturvetenskaplig undervisning och som har tagit fram en kodbok för detta ändamål. Utgångspunkten är sociokulturellt lärande, där kommunikationen är viktig för lärandet, där lärande innebär att socialiseras in i en diskurs och att språket används olika i olika kontexter. Undersökningen var till största delen kvantitativ och deduktiv men med kvalitativa inslag. Kodboken användes som analysinstrument och därmed gjordes en slags innehållsanalys.

Aspekter på flyttkostnader, fastighetsbildning och fastighetstorlekar :

This master thesis has three purposes. The first purpose is to give a theoretical background of how to divide up forest estates and to study how the legal system for these matters works. A literature study has been carried out to give the background and a theoretical model has been made for analysing the law cases. The first purpose also partly touched the decision process in dividing up forest estates from point of view of the law of land parcelling (FBL), point of view. The second purpose is to examine effects of a change of production requirements in 3 cap.7 § FBL as regards dividing up forest estates of private forest owners.

Produktutveckling och prestandatest av ett vattenvärmedrivet torkskåp : Jämförelse mellan tre utvecklade versioner av ett vattenvärmedrivet torkskåp

AbstractElectricity consumption is a globally increasing problem caused by the high share of electricity produced in coal power plants. These contribute to high carbon emissions when only about 1/3 of the heat generate electricity and the remaining 2/3 of the heat cools off. Combined heat and power plants (CHP) have high efficiency because they use the residual heat for domestic heating. The CHP plant often use fuels from renewable resources, giving them a lower carbon footprint, but are also depending on the heat demand. If electric powered products such as drying cabinets convert to heat powered products more environmentally friendly electricity will be produced by CHP plants, which can supplant electricity, produced from coal power plants and reduce carbon emissions.

Identifiering av merva?rden i EPC-projekt

In this report a study is carried out with the aim to identify added values of EPC projects implemented in schools in order to increase the interest of EPC projects on the market. The report examines how the planned maintenance, supervision, maintenance and corrective maintenance is affected, how insurance premiums and terms are affected, the indoor environment and how the tasks of the operating staff is changing. A literature study of energy savings, energy use in schools, maintenance and insurance as well as how energy efficiency improvements are related to the Swedish environmental objectives has been made. Visits were carried out in Ludvika, interviews were also carried out with operation technicians and local strategists in Ludvika as well as employees of insurance companies.Schools often have neglected maintenance and problems with ventilation and indoor environment. Schools also have a large energy saving potential due to their low utilization, mainly because they are empty parts of the year.
