Abstract: It is necessary for enterprise information systems to dynamically adjust its structure and behaviors to adapt to the continuous changes of business environment. The reconfiguration ability of business models is a key factor which influences the reconfiguration ability of the whole enterprise information system. Based on the analysis of reconfiguration-oriented design principles, a business rules based business model was presented, and description method for every type of business rule was shown in detail. In this model, by continuous decomposition of business elements, frequently-changing parts in business models were clearly separated from stable parts, and expressed by business rules, which significantly improve flexibility of business models. Finally the modeling process for this kind of business model was briefly proposed.
