Formalized Model of Stabile Reengineering Information System Functional Elements (Business Processes)

Abstract

The process of reengineering the functional elements of management information system must presented as stable, in which all the kernel functional components of the management information system should be saved. Problem statements: There is no formalized models for stabile reengineering for the functional structure (functional elements) for various information systems types, therefore the process of reengineering is not stabile and may be it finished with failure reengineering process or failure information system. Approach: The information system development Approach and the mathematical methods to formalized the detailed mathematical model for the information systems stabile reengineering, and at different stages of IS reengineering. Results: All process of stabile reengineering at the various stages of it was formalized in mathematical models. Conclusion: The developed models helps the system analyst to define if the reengineering process for the functional structure of information system will be stabile and effective or not, and if it more feasible than creating new information system.
