IEEE Transactions on Evolutionary Computation, vol. 12, no. 3, 343-354.1089-778Xhttp://dx.doi.org/10.1109/TEVC.2007.904343http://dspace.lib.cranfield.ac.uk/handle/1826/2677This paper emphasizes the necessity of formally bringing qualitative and quantitative criteria of ergonomic design together, and provides a novel complementary design framework with this aim. Within this framework, different design criteria are viewed as optimization objectives; and design solutions are iteratively improved through the cooperative efforts of computer and user. The framework is rooted in multi-objective optimization, genetic algorithms and interactive user evaluation. Three different algorithms based on the framework are developed, and tested with an ergonomic chair design problem. The parallel and multi-objective approaches show promising results in fitness convergence, design diversity and user satisfaction metrics.en-UKinteractive evolutionary computationmulti-objective optimizationdesign optimization, ergonomicsArticle
