Порівняння ефективності систем автоматизації виробництва по сукупності характеристик

Abstract

The efficiency indices of the built-in automation systems, which can be used for the assessment of the efficiency of different variants of the system construction are given in the paper. Methods of multicriterial comparison of the efficiency of different variants of production automation systems construction, presented by numerous quality indices are considered. The drawbacks of the known methods, based on the application of the resulting efficiency index, obtained by the summation of the weighted quality indices are described. The process of the optimal decision search is proposed to perform in two stages: determination of the set of the forward looking engineering solutions, selection of the optimal decision from previously determined set of the perspective decisions. At the second stage it is necessary to use the additive function for the convolution of the efficiency indices. Comparison of the efficiency of various forward looking variants of automation systems construction is carried out by the resulting efficiency indices. Final results, obtained in such a way, is more reliable as compared with the using of the additive function for the convolution of the efficiency indices without the preliminary search of the advanced systems, because the additive function is used only for the preliminary constricted set of variants of system realization. Analytical procedure of the search of the advanced engineering variants of automation system construction is developed.
