Multi-domain optimisation using computer experiments for concurrent engineering

摘要

It is a challenge to optimise several simulators in a multi-objective way in Computer-Aided Engineering (CAE) The technology of replacing each simulator with a fast statistical emulator based on a space-filling computer experiment is introduce. Acase study based on a rudimentary model of a car suspension system is conducted in full and is one of a series in a collaborative EU project (No. BE96-3046) which has a particular emphasis on multi-domain problems: mechanical, thermal, electrical etc. Inthe case study the objectives from three separate simulator responses are combined in different portmanteau criteria; global optimisation is then used to find Pareto solutions.
