Abstract: Interactive physical programming is based on physical programming, a new effective and computationally efficient approach for multidisciplinary design optimizationIt takes into account the designer’s or the decision maker’s (DM’s) preferences during the optimization process, and allows for design exploration at a given Pareto designThe approximate model of Pareto surface at a given Pareto design is developed using neural networks for design explorationAt the given Pareto design, a group of Pareto designs are generated randomlyThey’re brought to the decision maker using a Pareto visualization tool, and are evaluated with both qualitative and quantitative analysisA map from Pareto designs to their corresponding evaluation value is established using a neural networks model, it illustrates the decision maker’s local preference at the given Pareto designThen genetic algorithms is used in optimization to find the Pareto design which mostly accords with the decision maker’s local preferenceThe obtained Pareto design is used as the aspiration point in compromise programming, and the final design solution can be obtained

Key words: Physical programming  Interactive physical programming  Neural networks  Multiobjective optimization  Genetic algorithms  Interactive design  Compromise programming
