A Multicriteria Problem of Distribution of System Blood Flow among Organs and Tissues and an Algorithm for its Solution

A multicriteria mathematical model is proposed for finding the volumetric rate of blood flow in human tissues with a known volumetric system circulation rate. An algorithm is developed for decision-making as to distribution of the system blood flow among different tissues with regard for data on the oxygen consumption and carbon dioxide discharge in different tissues.

CRITERIA AND METHODOLOGY OF COMPLEX EVALUATION OF BITUMINOUS CONCRETE MIXER QUALITY

Summary The structure and sequence of technological operations of mixers for bituminous concrete mixtures, functioning in Lithuanian bituminous concrete mixing plants have been analyzed. The problems, which are subject to interest by the owners of bituminous concrete mixers, have been systematized. The necessity and objectives of quality evaluation of the functioning bituminous concrete mixers have been proved. A new multi-criteria mathematical model for determining quality of bituminous concrete—consisting of the sum of 4 group indicators, which evaluate quality of bituminous concrete mixture production in the mixer, environmental care, economy and technological universality—has been provided. The following 9 criteria make up the mathematical model, which can be used for calculation of quality indicator K of the working bituminous concrete mixer: accuracy of the bituminous concrete mixture content, produced in the mixer, ie the conformity of its component quantity with the project requirements (s); its t...
