Logical and probabilistic analysis of the reliability of the metallurgical complex electric supply

The paper deals with the problem of choosing the preferable electric supply scheme of the metallurgical complex from the reliability problem of view. The algorithm of solving this problem using the logical probabilistic approach is presented. The structural, logical and probabilistic models of the system's reliability have been developed for three power supply connection options. Computational studies have been conducted, and the contributions of the elements into the reliability of the system have been determined.
