RESEARCHES UPON THE STOCHASTIC ANALYSIS OF THE TECHNOLOGICAL EQUIPMENTS EXPLOITATION

The paper aim is to determine the failures probability appearance in the technological equipments working processes, in the hypothesis that these have a Markov structure. Starting from a not detailed block diagram of an equipment and also, from his global probability failure, one can attend his detailed form by calculation, based on the detailed logical diagram. A first step consist to establish the average rate of the failures intensities (lambda(i)) and then, of the repair rate (mu(i)), for the entire technological equipment group. Based on the detailed logical diagram of each equipment from the group, one can determine the number of those components that can may suffer failures, during the working process and corresponding to them, one obtain through calculation, the lambda(i) and mu(i) coefficients values using the Pareto method.
