Three Approaches to Evaluating the Performance of Active Reservation Systems

Relevance and purpose. One of the ways to improve the performance of control systems of technical objects is considered active redundancy. This method should reduce the damage to the malfunction of the automatic control systems in real time. The use of active redundancy makes it possible, due to a slight increase in the cost of control systems of technical facilities, to significantly reduce the damage from the malfunction of the controlled system, for example, a powerful power facility. However, in the literature there is no description of the mathematical apparatus that have allow an accurate assessment of the feasibility of using active backup systems. Materials and methods. Most publications suggest using active backup systems created by combining several identical elements that process input information using the same algorithms, the inputs of identical elements are connected together, and the outputs are combined through a decision maker element. Results. The article discusses three approaches to assessing the reliability of active backup systems. Theoretical approaches to evaluating the performance of such systems, based on mathematical logic and probability theory, are considered. Based on the findings, an approach is proposed to obtain a numerical evaluation of the reliability of the system of active elements.
