METHODICAL APPROACH TO ESTIMATION OF OPERATION EFFECTIVENESS OF INFORMATION SYSTEM WITH TEMPORARY REDUNDANCY
Annotation
A methodical approach to estimation of operation effectiveness of information system with temporary redundancy is proposed. Probability of successful implementation of the information system task is taken for the functioning efficiency index. An integral equation based on the theorem of total probability is used for quantitative estimation of the probability. The Laplace transform is used to solve the integral equations. Analytic expressions are obtained for the probability density of the excess time, the values of the first and second initial moments, the variance and the standard deviation. An approximate formula is used for the inverse transition from the Laplace image of the obtained solution to the time domain. The amount of information work performed by the system with temporary redundancy is estimated. A distinctive property of the proposed approach is accounting for results of monitoring the information system functioning.
