Method of Reliability Block Diagram Visualization and Automated Construction of Technical System Operability Condition

摘要

This paper describes the method of reliability block diagram visualization and automated construction of technical system operability condition, which is based on the reliability block diagram analysis with splitting into segments. The developed method includes RBD traversal to examine the topology of the diagram with subsequent identification of scheme's elements connection type for further construction of a technical system working condition. To verify the correctness of the developed method of automated construction of the operability condition of technical systems, the comparison of its results with the operability condition obtained using the recursive algorithm was carried out. The performance of the implemented software was studied as well using parallel and sequential combinations with different number of modules in the diagram. When the number of modules is 200, the performance of the developed method is higher about 25% comparing to the recursive algorithm.
