    Advanced computing methodology for general highly reliable systems

  • Original language description

    In our previous research we developed new methodology for high-performance computing which enables exact unavailability quantification of a real maintained highly reliable system containing highly reliable components with both preventive and corrective maintenance. Main objective of this paper is to generalize the original methodology so that to be used for unavailability quantification of a system with ageing input components with optional distributions of the time to a failure, as Weibull, log-normal, etc. For this purpose new findings in renewal theory (alternating renewal models) are demonstrated and derived. For computing implementation we derived an innovative equation to calculate unavailability function, not containing the renewal density, which is more effective than the corresponding equation resulting from the classic alternating renewal theory in which renewal density is included. The new equation undergoes the process of discretization which results in numeric formula to quantify desired unavailability function. This numerical process is elaborated for all previously intended stochastic component models. Found component unavailability functions are used to quantify unavailability of a complex maintained system. System is represented by the use of directed acyclic graph, which proved to be very effective system representation for computing highly reliable systems.
