1. 1. Evaluationg IT investments : a business process simulation approach

   Författare :Enrique Silva Molina; KTH; []
   Nyckelord :business process modeling and simulation; evaluating IT investments; dynamic information workflow model;

   Sammanfattning : Information technology (IT) is becoming the primary factordetermining the survival of most organizations. The differenttypes of systems and the wide range of objectives suggest thatdiverse evaluation methods are needed. LÄS MER

3. 2. Random Models in Time and Space with Financial, Economics and Engineering Applications : Structural Covariance in Space and Stochastic Variability in Time

   Författare :Nima Shariati; Statistiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cross-border spillover; Inter- and intralocation effects; Multivariate spatial regression models; Panel data; Spatial econometric models; Gamma distributed variances; Generalized Laplace distribution; Modulated volatility; Non-Gaussian time series; Road profile; Spatial vector autoregressive model; Outlier; Robust control chart; Robust estimation;

   Sammanfattning : In this thesis, we model stochastic processes in time and space. We focus on the processes whose covariance structure is either changing over the time span, or depends on the location in space. We develop models that appropriately describe and analyze such data behaviors in various different fields including finance, economics and engineering. LÄS MER

4. 3. Credit risk and forward price models

   Författare :Raquel M Gaspar; Handelshögskolan i Stockholm; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : This thesis consists of three distinct parts. Part I introduces the basic concepts and the notion of general quadratic term structures (GQTS) essential in some of the following chapters. Part II focuses on credit risk models and Part III studies forward price term structure models using both the classical and the geometrical approach. LÄS MER

5. 4. The Competition for Forest Raw Materials in the Presence of Increased Bioenergy Demand : Partial Equilibrium Analysis of the Swedish Case

   Författare :Elina Bryngemark; Patrik Söderholm; Anne Toppinen; Luleå tekniska universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; bioenergy; biodiversity; partial equilibrium model; forest raw materials; market competition; Sweden; Economics; Nationalekonomi;

   Sammanfattning : Growing energy use and greenhouse gas emissions have implied an increased attention to the development of renewable energy sources. Bioenergy from forest biomass is expected to be one of the cornerstones in reaching renewable energy targets, especially in forest-rich countries such as Sweden. LÄS MER

7. 5. A Framework for Cyber-physical System Tool-chain Development : A Service-oriented and Model-based Systems Engineering Approach

   Författare :Lu Jinzhi; Martin Törngren; Vangheluwe Hans; KTH; []
   Nyckelord :Cyber-physical system development; Model-based systems engineering; Tool-chain; Domain-specific modeling; Tool-integration; Co-simulation; Systems thinking; Industriella informations- och styrsystem; Industrial Information and Control Systems;

   Sammanfattning : The development of complex Cyber-physical Systems (CPS) requires tight interactions of projects, system components, stakeholders, data and models. These models and data support component design, which are implemented by various engineering tools used by stakeholders. Effective tool integration thus relies on development of tool-chains. LÄS MER
