To ensure the reliable operation of communication networks of the oil and gas complex, it is necessary to properly organize the process of maintenance and repair of equipment. As technology evolved, various strategies for maintenance and repair of equipment were developed in the industry, which improve the profitability of production. At present, a risk-based strategy is increasingly used. In practice, to apply this strategy, it is necessary to make a preliminary estimate of the magnitude of the risk based on the probability of equipment failure and the severity of the consequences of failure. As information sources, statistical data on equipment and failures, forecasts of technical condition and consequences of failures, simulation results, as well as expert estimates can be used. To simplify the process of analyzing input data and reducing the subjective uncertainty of expert data, it is advisable to use a decision support system that must rely on the apparatus of the theory of fuzzy sets and methods of collective expert assessments.
