This paper introduces that the representation and storage of hierarchical model via a database table, achieves the dynamic generation and management of model. It main achieves model base based on AHP. That addresses a number of unstructured or semi-structured problems such as assessment and prediction in the modeling. Focusing on the creation of their corresponding AHP-based method base is to solve practical problems. Experiments show that this method base can be well integrated with model base. So it will be applied in common AHP cases.
