ABSTRACT:
In a method for determining reliability characteristics for a technical installation, a single FMEA table covering all configurations is initially produced for the whole installation. In its lines, i.e. the description of faults and their consequences, the table also has the rate constants, test periods, repair times and consequences of failure, which are dependent on the configuration of the installation. The table explicitly records how the configuration-dependent entries depend on the respective configuration of the installation. In a further step, configuration-specific FMEA tables geared to a specific configuration of the installation can be extracted from this table. Using the configuration-specific FMEA tables, after conversion into Markov models, reliability characteristics can be calculated for the installation in the particular configuration. (FIG. 1)
