THE OPTIMIZATION OF CIS SUBSYSTEMS EVOLVING PROCESSES, BASED ON MULTIVARIANT INTEGRATION

In the article the questions of optimization of developments of subsystems of corporate information systems are considered. Modern information systems, include developed software, are used to represent difficult, multicomponent systems with dynamically changing structure that significantly complicates a problem of creation of rational architecture of corporate IS. Modern standards of creation of architecture don't allow to achieve the necessary targets because of the excessive abstractness, or tendentiousness. Authors offer the technique of design of rational architecture of corporate IS considering three main levels of components of architecture (business processes, hardware, software), features of their interaction and also ways to use the device of multiple integration for the solution of the tasks arising in the course of creation of corporative IS. In the course of development of rational option of architecture, the lifecycle spiral model assuming incremental development of architecture with periodic verification of the received results is widely used. For calculation of a matrix of preference of sharing of components of architecture in view of impracticality of use of statistics, it is offered to use sets of the metric indicators defining structural, process and user features of components of various levels. The offered approach allows to increase significantly efficiency of creation of corporate IS due to design of rational architecture.
