    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle; diesel engine; simulation; supercharging; drivability; toolbox; fuel economy; transient; modeling; turbocharging; control system; powertrain; emissions; performance; dynamic; system;

    Sammanfattning : Engine modeling and simulation have been necessary tools for efficient product development in the automotive industry for some time. The scope of this work is novel engine models, tools, and methods for powertrain research and development. LÄS MER

  3. 2. Configuration Design of a High Performance and Responsive Manufacturing System : Modeling and Evaluation

    Författare :Daniel Tesfamariam Semere; Bengt Lindberg; Bolmsjö Gunnar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Configuration; Modeling; Evaluation; Manufacturing engineering; Produktionsteknik;

    Sammanfattning : Configuring and reconfiguring a manufacturing system is presented as an issue with increasing importance due to higher frequency of system configuration or major reconfigurations to accommodate new set of requirements and/or the need to configure the system to make it usable across generations of products or product families. This research has focused in the modeling, evaluation and selection decisions which involves multiple, incommensurate and conflicting objectives. LÄS MER

  4. 3. On aircraft fuel system design : concept evaluation and system modeling

    Författare :Hampus Gavel; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : THE LARGEST AND most important fluid system in an aircraft is the fuel system. Obviously, future aircraft projects involve the design of fuel system to some degree. In this project design methodologies for aircraft fuel systems are studied, with the aim to shortening the system development time. LÄS MER

  5. 4. ForSyDe-Atom: Design of Heterogeneous Embedded Systems : Taming Complexity with Layers, Atoms and Patterns

    Författare :George Ungureanu; Ingo Sander; Reinhard von Hanxleden; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; system design languages; modeling; simulation; synthesis; embedded systems; cyber-physical systems; domain specific languages; systemdesignspråk; modellering; simulering; syntes; inbyggda system; cyberfysiska system; domänspecifika språk; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : The design of embedded systems is inherently complex for two main reasons. Firstly, it entails the combined knowledge and results from a vast set of mature, well-established, yet separate disciplines, such as electrical engineering, computer science, mechanical engineering, etc. LÄS MER

  7. 5. State-Oriented Business Process Modeling : Principles, Theory and Practice

    Författare :Ilia Bider; KTH; []
    Nyckelord :business process; dynamical system; formal semantics; persistent action; law-based programming; business analysis; business modeling; object-oriented modeling; conceptual modeling; workflow;

    Sammanfattning : In the last 50 years, a considerable amount of research workhas been completed in the mathematical system theory and theoryof control. Implementation of the results from this researchinto practice has drastically decreased the production costs.Most production processes are highly automated, and the use ofrobots in industry is growing.
