EXPERIMENTAL-DESIGN AND OBSERVATION FOR LARGE SYSTEMS

Large systems require new methods of experimental designs suitable for the highly adaptive models which are employed to cope with complex no n-linear responses and high dimensionality of input spaces. The area o f computer experiments has started to provide such designs especially Latin hypercube and lattice designs. System decomposition, prevalent i n several branches of engineering, can be employed to decrease complex ity. A combination of system decomposition using a sparse matrix metho d, experimental design and modelling is applied to one example of an e lectrical circuit simulator producing a usable emulator of the circuit for use in optimization and sensitivity analysis.
