The important feature of the modern automated telecommunication systems and control systems is the broad usage of computer aids both special-purpose hardware, operating according to the strictly specified ("sewn") algorithm and general-purpose computer based on the high information redundancy and generally used several protocols and data formats including adaptive ones and admitting variability of the accepted decisions. It-s reasonable to introduce objective function realization probability term, which can be defined on the basis of information system model (IS) as input stream of the ordered data changer into the output stream for quantitative description of infocommunication systems cooperation. They are connected by objective function realization through discrete transform. Output stream synthesis process as a result of commands chain fulfillment, realized specific algorithm branch is presented as point movement which features information system state on multidimensional discriminatory surface in the coordinate system of input streams (signals) and system responses. The presented system considers a range of factors rejected or roughly approximated in the famous simple models and can be used for conflict operation of real infocommunication systems.
