Developing better designs using computational intelligence
There's an increasing demand for engineers to make the 'best' possible design decisions while decreasing costs and at a faster pace. This requires knowledge of methods in design optimisation which have become an integral part of product design and decision-making activities when developing mechanical structures, devices or systems.听 听
Traditional design optimisation relied on manually identifying the right combination of design variables. This process is time-consuming and involves a trial-and-error approach to satisfy design objectives. Design optimisation allows for thousands of designs to be experimented with on a computer using mathematical formulations and simulations to find the optimal design relative to a set of performance objectives and constraints. Maximising factors such as productivity, strength and reliability, optimisation techniques have helped automate and improve efficiencies while reducing costs in product design, manufacturing processes and project planning.听听

Impact
We're developing cutting-edge, practical听and efficient algorithms and frameworks to support multidisciplinary optimisation. These design optimisation methods, which provide solutions for a wide variety of design problems, address fundamental challenges and uncertainties in the optimisation process including:听
the presence of multiple conflicting听performance criteria听such as minimum cost, maximum reliability, and maximum strength听
the presence of several design variables and/or听design constraints听
computationally expensive simulations听
highly听non-linear听programming听or black-box response functions听
hierarchical objectives involving decision-making at multiple levels.听
Our research is frequently published in leading journals such as the Institute of Electrical and Electronic Engineers (IEEE) Transactions on Evolutionary Computation Journal and the American Society of Mechanical Engineers (ASME) Journal of Mechanical Design.听
We're running several externally funded projects which include the Australian Research Council (ARC) Discovery projects, Future Fellowship听and the Endeavour Fellowship.听听
