    Abstract:

    1. Past Research Experiences and Recent Research Activities in the field of
    Computational Methods in
    Engineering Design
    About 15 years of research of H.-J. Sebastian in the area of Computational
    Methods in Engineering
    Design was and still is focused on 4 topics:

    1.1. Routine and Innovative Design (Configuration-type Design Problems)
    a. Design Methodology (work started in 1985)
    - Knowledge-based design methods for configuration-type of design problems;
    - Optimal design (one design objective, multi-criteria design problems),
    (collaboration with A. Agogino
    started in 1989);
    - Uncertainty and imprecision in design.
    The approaches elaborated cover the conceptual and detailed design phases as
    well. A hybridization of
    knowledge-based methods with optimization and/or fuzzy technology was
    successfully realized.

    b. Development of Design Tools
    The Expert System Workbench KONWERK was implemented during 1991 to 1995 using
    the language
    LISP. The methodology mentioned above is available within this workbench.
    Several real world design
    problems have successfully been solved using KONWERK.

    c. Development of Applications
    - Configuration of Future Space Launch Systems (together with the German
    Aerospace - DLR Cologne);
    - Layout Design of a Passenger Aircraft Cabin (Airbus 340) (joint research with
    the Hamburg University);
    - Personal Computer Configuration using a Fuzzy MADM method for fitness
    evaluation within a Genetic
    Algorithm;
    - Configuration Design of large Conveyor Belt System for the Coal Mining
    Industry (granted by
    TAKRAF company).

    1.2. Imprecision in Design: Fuzzy Engineering Design
    A joint project on "Fuzzy Engineering Design" (grant by the NSF and the DAAD) of
    the Caltech
    Engineering Design Laboratory (E. Antonsson) and the Aachen Institute of
    Technology was successfully
    realized from 1996 to 1997. Within the project computational intensive methods
    have been developed and
    implemented. In particular, modifications of the Method of Imprecision have been
    elaborated by
    combining this approach with Fuzzy MADM. The implementation was done in C++. The
    outcome of this
    research which has been continued after it´s termination in 1998 are two joint
    monographs, several
    conference papers, in particular a joint paper with E. Antonsson and R.
    Schleiffer, which was presented
    during the Design Methodology Conference in Las Vegas in 1999.

    1.3. Simultaneous Engineering
    H.-J. Sebastian and his group participate in the Sonderforschungsbereich (SFB)
    361 of the DFG ("the
    German NSF") on "Models and Methods for Integrated Product and Process Design"
    since 1998. The
    research topic is uncertainty modeling in Simultaneous Engineering. There are
    several applications within
    this SFB e.g. an application dealing with Windmill Design.

    1.4. Design Simulation using Agent-based Approaches
    At the beginning of 1999 a research project with Bombardier Europe on simulation
    of passenger flow in
    double-level rail-train cars was started. The goal is to justify some important
    design parameters.
    Agent-based simulation is used in order to model the microscopic behavior of
    passengers more
    realistically. First results of those computationally extensive methods are
    promising.
    There are many publications of the results H.-J. Sebastian achieved within the
    topics 1.1. and 1.2. (list of
    selected publications). However, until now related to the new topics 1.3. and
    1.4. there are only research
    reports (drafts) and conference presentation but not yet journal papers.
