A Study of the System's Hierarchical Structure Through Integration of Dematel and ISM

To ensure the hierarchical structure of complex system illustrative and reasonable, the new method is presented to build and adjust hierarchical structure of complex system through integration of decision making trial and evaluation laboratory (DEMATEL) and interpretive structural modeling (ISM) models. First of all, the rationale and procedures of integrating DEMATEL and ISM are analyzed; then the method to perfect system's hierarchical structure with dummy nodes is proposed, which can be viewed as the images of the original nodes in system's hierarchical structure; at last, a material example is given to verify the methods mentioned above
