The paper deals with the problems of modern corporate information systems. It is necessary to carry out the structural synthesis of their components. It is important that there is a choice of the required number of parallel processing in the databases, as well as the assignment of priorities for the execution of the corresponding processing conditions. On the basis of enumeration schemes, alternative variables will be introduced. When calculations are carried out using the developed models, it is possible to calculate the values of predictive estimates for each of the search steps. That is, many promising options for information and telecommunication systems are selected, with the additional inclusion of procedures for taking into account restrictions and multi-criteria.
