Keywords: Pareto surface, approximation, multi-criteria optimization, trade-off analysis

A local analysis of Pareto solutions in multi-disciplinary optimization is considered. A quick local analyser concept is proposed. It is based on a local sensitivity analysis. The sensitivity analysis is performed on the basis of local approximations of the Pareto surface. Criteria for detecting non-smooth Pareto points are analysed.
