Multi-Objective Modeling for Engineering Applications in Decision Support

In engineering computer-aided design, the final choice of the design might be supported by multicriteria optimization; we show here, however, that multicriteria optimization can be also used as a tool of helping in a flexible analysis of various design options or various modeling and simulation variants, even from the beginning stages of model construction. Various formats of defining linear and nonlinear models are discussed together with related problems of inverse and softly constrained multi-objective simulation. Such techniques are illustrated by engineering applications of a software package DIDASN++ in mechanics, automatic control and ship navigation.
