  2. 16. Value Driven Design : a methodology for value-oriented decision making in preliminary design

    Author : Alessandro Bertoni; Sergio Cavalieri; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktinnovation; Product Innovation;

    Abstract : Making design decisions during preliminary design of a complex product, such as an aircraft, is a difficult activity. Numerous teams, acting on a global scale, take part in such design activities, approaching the problem from different perspectives and at different levels of granularity. READ MORE

  4. 17. Adaptive structural design - Integration of computational tools for CAD, adaptive FEM and optimization

    Author : Per Kettil; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive; structural mechanics; optimization; integration; FEM; CAD; design;

    Abstract : BackgroundConstruction is one of the largest industries with major impact on economy, environment and society. Improved structural design is important since the decisions made during the design process strongly influence all later stages, i.e. READ MORE

  5. 18. Optimization and Model Validation of Transonic Compressors

    Author : Lars R Ellbrant; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compressor; optimization; design; metamodels; CFD; validation; multiobjective;

    Abstract : Economical aspects such as reduced specific fuel consumptions and ever growing environmental requirements on emissions and percieved noise levels, are the major drivers in the search for improvement of aircraft engines. For turbofan engines, the global trend is towards higher efficiency which is accomplished by increasing component efficiencies, the bypass ratio and overall pressure ratio while keeping the engine weight low.

  6. 19. Composition and Optimization

    Author : Morgan Ericsson; Uwe Assmann; Växjö universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; software composition; software reuse; optimization; high-performance computing; Datavetenskap; Computer and Information Sciences Computer Science; Data- och informationsvetenskap;

    Abstract : A recent trend in software engineering is to delay design decisions. One motivation is that requirements or properties of the application and environment are not known until later in the design and development process. This continues to hold for design decisions in a high-performance context where e.g. READ MORE

  7. 20. Computational Methods in Conceptual Structural Design

    Author : Vedad Alic; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conceptual design; conceptual structural design; ground-borne vibrations; form finding; optimization; dynamic relaxation; graphic statics; reciprocal figures; strut-and-tie; finite element method; isogeometric analysis; NURBS; CAD; numerical modelling;

    Abstract : Conceptual design is the first phase in the design process in which all the requirements and design objectives are synthesized into conceptual alternatives. In practice today, major decisions regarding the buildings function, massing, and overall form are usually made during the first phase. READ MORE
