Establishing hierarchy structure in complex systems based on the integration of DEMATEL and ISM
Ling Zhang · Guanli kexue xuebao · 2008
Establishing hierarchy structure is generally the foundation of the analysis of complex systems.To make the hierarchy structures of the complex systems illustrative and reasonable,a new method is first pro- posed to establish the hierarchy structures for complex systems based on the integration of DEMATEL and ISM after the theoretical foundation and corresponding steps of the integration are analyzed;and then the concept of dummy node is advanced to improve on the hierarchy structures of the complex systems;finally an example is used to illustrate the methods mentioned above.Through the integration algorithm mentioned in the paper,the rearchability matrix of ISM can be obtained easily.
