This thesis is concerned with the development of robust evolutionary methods and a framework in which different multi-objective and multidisciplinary problems in aeronautics can be designed, analysed and optimised.The methods couple a robust evolutionary optimiser, parallel computing, asynchronous evaluation strategies and a hierarchical topology of fidelity solvers that reduce the computational expense of multi-objective and multidisciplinary design optimisation processes.The methods and framework are applicable to single and multi-objective, inverse or direct, complex engineering problems that can be highly non-linear, multi-modal, involve approximations, be non-differentiable, with convex, non-convex, discontinuous Pareto First and foremost, I must thank my family and Isabel, for their love, constant support and encouragement.Being apart and away from home has not been easy but they continued to believe and encouraged me to go forward in all aspects of life.My adviser, Dr K Srinivas was a constant source of advice through my graduate studies.He gave me numerous opportunities to co-author technical papers and present results to engineering journals and at scientific conferences.These experiences have done a lot to enhance my professional growth and I am grateful for all his efforts.I am also deeply indebted to Dr Eric J. Whitney who, on occasions too numerous to mention, provided helpful insights and discussions into the research topic.For the past three and a half years Eric has not only been a great friend but a constant adviser and critic to many aspects of my research.Professor Jacques Périaux provided invaluable inputs and advice for this work.For the past three years Professor Périaux has remained active in providing challenging topics and outlined the connection between what is expected from academia and industry.He has remained active via tele-communications, fax and email while being located at the Pole Scientifique in France and through several visits to The University of Sydney.His extraordinary efforts are greatly appreciated.
