A Study on Flexibility of ERP System Based on Grey Evaluation Model

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.
