An algorithm to assess the conclusion fuzzy related to “General reliability” GRgen in the operation of automation systems (AS) have been treated in the paper. It is provided an independent analysis of the performance, carrying out the general conclusion in the operation of AS for the system of automated switching the reserve (ASR), through the longitudinal couple. The assessment of the input parameter in the System with the Fuzzy Logic (SFL) “Severity” (SV) of the initial fault D, above SE, as a consequence of the appearance of sequence of events associated to the branch of the tree of events fuzzy (TE) has a subjective character and is realized under the defined criteria by the specialists in the domain. An algorithm of assessment of the “SV” parameter for each brunch from TE, using the multitude of minimal cuts associated to AS has been proposed. For automated switching system it has been generated TE fuzzy composed of 24 branches and it has been assessed input parameters of SFL – Level of Appearance (LA), Severity (SV) for the sequence of the events associated to the branch TE. It has assessed also the conclusion fuzzy AS for the sequence of the events associated to the branch TE, using the base of rules SFL and the general conclusion fuzzy SGgen together with its centroid value GSGgen. |
