Date and venue

Lupe

Monday, the 19th of May 2003, to Friday, the 23rd of May 2003

Welcome and registration as well as lectures will take place on the Schleuseninsel (lock island) which is the site of the former Berlin Model Basin (VWS). You will have to cross a slender passenger bridge (a light blue steel construction) to reach the red brick building.
The auditorium is called: VWS 128 (grosser Saal).

The full address is:
Technical University Berlin
Mueller-Breslau-Strasse (Schleuseninsel)
D-10623 Berlin

As you may see from the map, on foot the location is some (max.) 10 minutes from Berlins central station Bahnhof Zoologischer Garten and also some (max.) 10 minutes from Ernst-Reuter-Platz with an underground station of U-Bahn U2. It is less than 5 minutes from S-Bahnhof Tiergarten, i.e., a station of Berlin urban rail system called S-Bahn.
From the institute of Land and Sea Transport Systems it takes a 10 minutes walk along the Landwehrkanal.

Berlin in May May usually is considered the nicest months of the year, the weather typically being sunny and dry with temperatures from 15°C to even 25°C. Berlin offers many cultural and recreational events and an abundance of culinary delights, bearing the great potential for a good time.

So, in addition to the summer school’s pleasures, Berlin simply is one of Europe’s most exciting cities.

Aim and scope of the summer school

Formal and automated optimization is increasingly recognized as a key technology that enhances and complements state-of-the-art processes of product development. The school introduces engineering professionals, scientists and post-graduate students to the methodology and the application of optimization methods, updating and extending their skills and competence.

The topics to be covered are deterministic and stochastic techniques for single- and multi-objective constrained optimization. Optimization techniques will be presented from a generic point of view as well as from a design-oriented perspective, allowing an appreciation of projects and applied work done in the marine field. Both merits and limitations shall be highlighted. Emerging techniques like optimization on the basis of neural networks will also be addressed.

The school brings together the combined expertise and knowledge of Europe’s industry and academia in this cutting-edge field in order to complement the curricula of WEGEMT’s associated institutions that provide higher education in naval architecture, ocean engineering and related sciences. This intensive course enables the participants to subsequently utilize optimization in their daily design work and research, respectively – thus contributing to higher competitiveness in the global market.

Background

Computer systems for modeling, simulation and assessment in the design, production and operation of marine systems are more and more applied to speed-up and improve the quality of processes, products and services. As the time allocated for design decreases while the demand on the performance of the resulting system is constantly on the rise, a tight information technology (IT) integration is needed in order to take full advantage of the various tools of Computer Aided Design (CAD), Computational Fluid Dynamics (CFD), Finite Element Methods (FEM) etc. So as to view and develop design alternatives and variants effectively and efficiently, optimization has been intensively researched.

Along with many national research grants the European Union has financed a considerable number of projects on optimization over the last years, e.g. FANTASTIC - Functional design and optimisation of ship hull forms (5FP GROWTH), FRONTIER - Open system for collaborative design (ESPRIT IV), OPTIM - A shape optimization tool for multi-disciplinary industrial design (Brite Euram II), all of which have been largely supported by industry.

The computer resources now available in design offices are approaching the level at which complex problems can be reasonably covered to benefit decision-making. It therefore is appropriate and timely to hold an intensive advanced course on the topic of optimization in marine design.

Concept

The summer school is expected to attract about 50 participants, the majority of whom will come from all over Europe. The typical profile of a participant is that of a young scientist or project engineer who has to combine operational, management and strategic skills in her or his daily research and design work, respectively.

The school’s official language is English. The program integrates basic, intermediate and advanced topics to be presented from a broad and general point of view. The material will be taught in 45-minute sessions as lectures at a high post-graduate level. In addition, presentations on elaborate examples will be given in conference style, allocating time for detailed coverage. Illustrative examples are intended to improve the understanding of the methods taught in the lectures. They also motivate the utilization of the entire spectrum of available optimization techniques.

On the third and fourth day there will be hands-on sessions in a computer laboratory. The lab sessions will be based on state-of-the-art software tools available and familiar to the lecturers. The hands-on sessions are devised to have the participants put the theory into practice. In this way the school’s immediate benefit to the student is considerably strengthened. The lab examples shall be worked on in small groups in order to facilitate mutual support and develop closer multi-national relationships. Additional time slots may be allocated for participants who would like to present their own research.

Sufficient time for both discussions and recreation will be ensured by frequent brakes - extended lunch brakes along with shorter coffee brakes in the mornings and afternoons. A social event is planned for Tuesday evening so as to initiate contacts between individuals in a multi-cultural atmosphere as early as possible.
