The analysis of usefulness of operational potential consumption models to control complex technical systems maintenance

The carried on studies consider a crucial complex exploitation system of strategic importance from the national economy point of view. In case ofsuch class of systems, operation and service processes should be executed according to maintenance strategy named maintenance strategy by controlled consumption of operational potential. Thanks to it, optimal amount of operational potential included in the system can be transformed into the effect of the system operation. To execute exploitation processes according to the mentioned above strategy a model of operational potential consumption process should be implemented. The model estimates amount of operational potential consumed during exploitation processes execution. During carried out studies, models used to manage exploitation systems maintenance were identified. In the paper, identified models are divided into groups of analytical, stochastic and system ones. Next, usefulness of each group of models to control processes of exploitation phase of crucial complex strategic exploitation systems was discussed. As a result it was stated that it is necessary to create the universal system model, which can project influence of forcing factors on a s tate of technical object being a part of considered class of technical systems. In the paper, a structure of created universal system model was also proposed. This model was created by implementation the artificial intelligence techniques in form of genetic algorithms and fuzzy logic. Fuzzy logic was used to model approximate character of model input data and genetic algorithms were used to optimize a value of model output data.
