Reconfiguration rule based impact analysis method for enterprise information system

It is necessary for enterprise information system to frequently reconfigure itself to response to continuous changes. How to ensure completeness and soundness of reconfiguration is a key problem in reconfiguration engineering. A specific reconfiguration requirement directly impacts business models, and is mapped to software system's changes. This paper firstly proposes a reconfiguration-oriented and business rule-based business meta-model, based on which, a unified reconfiguration process framework is described briefly. Subsequently, it classifies reconfiguration operations, with reconfiguration rules defined for every type of reconfiguration operation, and presents an impact analysis algorithm based on reconfiguration rule in detail. Finally a practical case is shown to validate the method.
