Entropy-Based Complexity Metrics for Business Models of Enterprise Information System
Zhong Wang · 2006
The complexity of business models determines the complexity of enterprise information system,thereby im- pacts reconfiguration performance of the system to a great extent.Current researches focus mostly on complexity met rics of code-level software systems,and pay little attention to business model's complexity metrics.To quantitatively measure model complexity,a multi-layer architecture of business models is firstly shown,in which a business model is divided into a set of Basic Model Units (BMUs) by the dependency and decomposition relationships between business entities.Then an entropy-based complexity metrics is emphatically presented,in which the complexity of model enti- ties,dependency relationships,and business models can be recursively calculated by calculating the complexity of BMUs.Finally,a practical case is brought forth to validate the metrics.The method in this paper has great signifi- cance to thedesign and implementation of complex information systems.
