OPTIMISATION OF COMPOSITE AIRCRAFT PANELS USING EFFICIENCY ENHANCING EVOLUTIONARY ALGORITHMS

摘要

The use of Evolutionary Algorithms is a promising approach to solve complex optimisation problems such as the minimum weight design of composite aircraft structures. The main drawback of these probabilistic algorithms is the large number of design configurations that have to be analysed. Two methods are presented that enhance the efficiency of Evolutionary Algorithms: an adaptive adjustment of optimisation parameters as well as an approximate evaluation of design alternatives using a support vector machine classification. It is shown that both have the capability to reduce the computational effort considerably.
