The work describes the results of research aimed at developing a methodical apparatus and improving software and tools for substantiating solutions for the creation (development) of distributed information-control systems of an organizational type.
The structure of distributed information-control systems of the organizational type is considered, in which the typical elements of the system are singled out. The structuring of the initial data is done, a verbal and formalized statement of the problem of justifying solutions for the creation (development) of distributed information-control systems is proposed, and the structure of the solution is described. The essence of the task is to choose such solutions for the creation (development) of the systems that will ensure the maximization of the efficiency of the functional processes implemented in the system, with the mandatory implementation of the highest priority functional processes, the achievement of specified maximum permissible time and probabilistic time characteristics of the performance of functional processes, as well as the implementation of restrictions on the time and cost parameters of the process of creating (developing). The analysis of the algorithmic complexity of the solution of the problem posed showed that this problem is NP-hard. In this connection, the possibility of using approximate methods of finding solutions has been studied and confirmed. On the basis of these methods, the methodological apparatus for the formation of solutions for the creation (development) of distributed information-control systems in the conditions of resource constraints is proposed in the article, including a number of models, methods of algorithms and procedures. This methodical device is proposed to be implemented in an automated decision support system that allows to find for the solution of the task with the use of computer facilities and significantly reduce the labor costs for the search for such a solution.
