the competitive environment and changing business processes propose new requirements to ERP system's flexibility and its evaluation becomes the first and critical step to solve these problems. This paper begins with the analysis of flexibility's definition.Basing on the core idea of three-tier software architecture,the author refines the index system from the aspects of presentation flexibility, business flexibility and design flexibility. Then,treating the grey theory as a guide, the evaluation system is established by integrating AHP and Grey Evaluation Model.Finally,the corresponding example is given to illustrate the model.
