Available optimisation tools6 Sample Clauses

Available optimisation tools6. Many dedicated tools are available in commercial software tools, like CAD tools or CAE packages like FEM codes for example. These tools are normally very efficient in the context of the domain covered by the package itself. There are now complete environments dedicated to optimal design and able to deal with any set of analysis tools. One of them is the “modeFRONTIER environment” 7. The capabilities of such a tool cover: • The easy integration of any analysis tool using text files as inputs/outputs and able to be run in batch mode, and with specific connection with current tools (excel, matlab…). Several calculation chains can be managed, thus allowing multi-disciplinary problems. • The formulation of the calculation and optimisation process in terms of design variables, outputs, objectives, constraints, • The import (existing database) or generation (design of experiments techniques) of candidate designs databases, • The construction and adjustment of mathematical models based on a design database (response surfaces, neural networks…), • The optimisation functionality, starting from a given set of designs and operating any algorithm within a large range of available algorithms, thus allowing to smoothly adjust the search strategy to the • Design problem, including multi-criteria multi-objective aspects (pareto search), • Analysis of designs database to extract maximal information: trends, sensitivities, correlations, statistical characteristics, designs filtering, etc… • Multi-criteria decision making tools, enabling to sort out a number of candidate designs from a limited set of choices and preferences set up by the designer, within a multi-dimensional design space. This may be performed on any database (imported or generated) where designs are defined through a finite number of attributes within which the designer can show preferences. • Generation of perturbation and extraction of robustness information as well as performance information (robust design).
