Fuzzy identification of a threat of the inability state occurrence

What is it about?

In the case of crucial technical systems, the necessary condition for the proper management of the operation and maintenance is the minimisation of threat of the inability state occurrence. Expressing this objective in an analytical form is an essential element of the operation correctness assessment and optimal maintenance management. It involves modelling of the technical state and the operation and service activities in a coherent way. Unfortunately, in the case of huge and complex technical systems the analytical and stochastic models are inadequate. Therefore, it was decided to use a system approach to the issues under consideration. Firstly, as a fundamental, the operational potential was introduced. Subsequently, the potential was described in the fuzzy technical state space. Thanks to it, the amount of the operational potential which can be transformed into the effects of the system operation and the degree of threat of the inability state occurrence were expressed in an analytical form. The proposed theory was applied to analyse the results of the operational tests accomplished by using an OP-650k-040 power boiler. As a result, the usefulness of the approach in the case of complex, crucial technical systems of strategic significance has been proven.
