THE STUDY OF THE DIESEL MOTOR POLLUTION USING THE FUZZY LOGIC AND FAHP ALGORITHM
Through this paper we introduce a calculation procedure of the harmful (pollutant) substances produced by diesel motors in their operating process. This new procedure implies the use of experimental data (of the measurements made in the laboratory or test stands) with the help of which weighted averages are formed. The calculation of the weights is realized through the FAHP method (“FUZZY ANALYSIS HIERARHICAL PROCESS”) using the triangular cut fuzzy numbers. It is known the fact that in a weighted average, the weights can be chosen in more ways than one and that there exists a series of weights of the best approximation, so they obtained weighted average is a regression. The series of weights of the best approximation is materialized through the eigenvalues and eigenvectors methods. The embedding of the fuzzy numbers in the fuzzy number lot is realized through a convex combination procedure, which together with the cut fuzzy number provide us with 2 parameters, that can be than used for the choosing of situations as close as possible to reality. The paper ends with a case study in which the pollution is produced by more types of auto vehicles equipped with diesel motors (cars, minibuses, motorbuses and trucks). Beforehand a study is realized regarding the optimization of the mixture of the fuel with the air (fresh load).Key words: study pollution, Diesel motor, Fuzzy logic, FAHP algorithm
