The article deals with the moral durability indicators forecasting of the distributed information systems. Dealt with a situation where the limit state of the information system occurs due to reduction options for restoration of its resource. The reasons for this is the obsolescence of the hardware components, technologies of repair, removal from the production of components. Forecasting is performed on the basis of the dynamic multi-model analysis of contributions of different groups of the equipment items and subsystems recovery of a technical resource in changing the limiting state probability. Is given for the first time obtained the analytical expression, allowing you in general assess the magnitude of gamma percentage of the residual service life of the information system as the solution of an integral equation of the obsolescence of the third kind. The method of iterative approximate solution of this equation described. The expressions are obtained for the evaluation of limit values of indicators moral durability of the information system, as at the ideal subsystem resource recovery, and its total absence.
