A Synthetic Method for Examination of Potential Reliability and Safety Level Demonstrated by Technical Facilities During Their Lifetime

摘要

The paper presents fundamentals for an innovative method that takes advantage of diagnostic information defined with participation of an expert. (presented as a score of points). Defined number of points is assigned to each signal change, depending on the signal value and the moment when the change occurs, whilst the number of points is preliminary defined by an expert. The proposed innovative method consists in the use of signals represented by the scores to determine combined status equations [3, 5] for parameters of the adjustment control state and technical state (equations 3 and 4) and then parameters of reliability and safety (equations 5 and 6). Such an approach enables continuous monitoring of the reliability and safety states of facilities during their lifetime. The presented approach may prove to be extremely useful as it unambiguously presents wear and tear of the facilities and enables to predict when the facilities should be repaired (overhauled).
