The automated system for developing diagnostic support works as follows.

In the memory block Z, a set of types of failures of the object of diagnosis is recorded, information about which is supplied to the information bus 1. The generator of the diagnostic model 2 forms a diagnostic model based on data about the object of diagnosis and a set of failures. In block 4 of obtaining estimates of diagnostic signs, the model is analyzed, which is formed in the generator of the diagnostic model 2 and in the nominal process simulation block 5. The signs enter the input of the characteristic deviation analyzer b, where they are compared with the data of block 5 of the simulation 7/0 of the nominal process. As a result, deviations of the characteristic values are formed. The acceptance control unit 7 analyzes the information of deviations and possible emergency processes, the information about which is recorded in the memory unit 8. As a result, a fact of failure is formed at the outputs of the acceptance control unit 7, on the basis of which the failure site analyzer 9 forms information about the failure site, which enters the shaper of the state of the object 11, which collects information about all failures, and forms the vector of the state of the object. The system resource analyzer 12 analyzes the vector /5 btan of the system and its resource and issues the optimal version of the system reconfiguration, which is carried out by the reconfiguration block 13. Signals for controlling the blocks are generated on the output bus 10.

Thus, the claimed system has wider functional capabilities, namely, the ability to develop diagnostic support and carry out system reconfiguration taking into account system resources.
