Analysis of the operational efficiency of complex automation systems and the calculation of their reliability on the basis of continuous models

The problems of technical-economical analysis and efficient operation of complex automation systems (CAS) are discussed. The CAS is considered to be able to operate under remote or direct administration. The scientific literature on comparative studies of the CSA reliability and cost under different conditions is lacking. This paper investigates the conditions that can increase the CAS reliability and lower its operating costs. The availability factor and cost characteristics are presented for various periods of operation of the CAS equipment. The study shows that the remote administration mode is more cost-effective in the long term. The results of research substantiate the choice of operational modes of the CAS equipment depending on the period of operation.
