基于熵的信息系统业务模型复杂性度量

he complexity of business models determines the complexity of enterprise information system to a great extent, thereby impacting there reconfiguration capability of the system. A multi-layer architecture of business models is shown, with which the business model is divided into a set of Basic Model Units (BMUs) by the dependency and decomposition relationships between business entities. An entropy-based complexity metrics is presented, and the complexity of entities, dependency relationships and business models can be calculated recursively by calculating the complexity of BMUs. The methodology is validated through a practical case at last.
