Product and System Optimisation
Incorporation of Product and System Optimization (PSO) Methods into
Compact, Reliable Design Cycles
Workshop Description
This workshop is concerned with educational & awareness issues,
including identifying barriers to successful uptake of emerging and
relatively mature technologies. The workshop will be structured
into two parts, a discussion session where issues are identified
and technical presentations where specific methods are presented
along with summaries of state of the art. The technical focus for
this workshop is Design of Experiments and Response Surface
Analysis. The workshop will also address the following questions:
• What are the real barriers to uptake?
• What can we conclude from the results of FENET survey on
PSO? survey report
• What type of documentation for best practices is needed?
Presentations
Optimized and Reliable Structures - A Contradiction in Terms?
R. Helfrich (INTES GmbH - Germany)
The ESPRIT project ASRA-HPC Integration of structural mechanics, optimization and reliability
analysis
- solution of a combined optimization and reliability problem in an
one-step approach
State-of the art technology for both domains
- High Performance Computing
- Adequate solution algorithms
GUI support for problem setup Solution of industrially relevant problems
Discrete Variable Optimization using MSC.Nastran SOL200
Hans Sippel, MSC.Nastran Europe
- Discrete Variable Optimization
- Conventional optimization uses Mathematical Programming that yields
continuous design variables
- These design variables are not immediately usable ( i.e. you cannot
make a plate of thickness 0.37582 cm ).
- With discrete optimization, the user can specify thicknesses
available: according to standard gauges
- Three methods: Conservative Discrete Design (CDD) / Design of
Experiments (DOE) / Rounding up/off
- Implemented as a postprocessing step to a continuous solution, this
means 1 additional FE – analysis
