Multi-Objective Reconstruction of Random Media

Popis výsledku v původním jazyce

To simplify a numerical analysis of complicated real microstructures, a material representative volume element is defined. It is based on a binary (black and white) image, which statistically resembles a corresponding real microstructure. Several statistical descriptors suitable for the microstructure characterization of a random media can be considered. Then, for example a unit cell can be derived from the optimization procedure formulated in terms of selected statistical descriptors. The aim of the work described in this paper is to resolve this issue using multi-objective optimization techniques. The goal is to approximate as closely as possible the true Pareto front as a trade-off of competing objectives. The performance of the multi-objective algorithm is verified by the reconstruction of given artificial images and is compared with results of the single-objective counterparts.
