Matrix model to determine reliability function of complex technical systems

Reporter: Ivanović G.

     The function of reliability of complex systems can be determined in the already traditional manner, by cross section and union of events, or by the combination of all possible events of failure and operation of the system, then through their probabilities, especially in case of non-elementary series and parallel connection of system elements. However, this can sometimes become the source of considerable difficulty from the standpoint of determination of failure and operation, as well as a large number of members when determining reliability function of a system. Because of this, it is sometimes impossible to es timate reliability of individual system parts.
     Bearing the previous in mind, this paper presents the procedure of matrix determination of possible events of proper operation of individual parts of the system as well as of the whole system of complex connections. On the basis of this procedure it is possible to estimate probability of proper operation, in other words, the reliability function of the system and/or of its individual parts. The SYREL software has been developed to calculate the reliability function.
