Method for Determining the Functional Survivability in Case of Decentralized Control of Intelligent Service

In this paper the method for determining the functional survivability of intelligent superstructure, that performs decentralized control of the process of providing intelligent services is proposed and also are obtained formulae for estimation functional survivability for providing intelligent services the performance a subset of functions that realize the purpose of the functioning of the system (the provision of intelligent services of a certain class), and also performance of at least of one of the functions from a subset (providing at least one kind of certain class intelligent service). The received formulae can be objectively used at the design of the control system over the intelligent service, at the choice of a control principle, at the decision of the problems of control system functional survivability increasing over intelligent service
