Obtain System Structure by Analyzing Elements Behavior Sequences with GRA-based ISM
It is generally the starting-point and foundation of complex systems analysis to establish hierarchical structure, with interpretative structural modeling(ISM) as the most popular approach. It is pointed out that the traditional way to establish adjacency matrix in ISM has its limitation, and the necessity and flexibility of integrating the grey relational analysis (GRA) and ISM is discussed. Adopting GRA, an improved ISM, called GRA-based ISM is proposed. GRA-based ISM is to obtain system structure by analyzing the behavior sequences of its elements. The adjacency matrix is no longer generated by subjective assumption, but derived from the grey incidence matrix in GRA. With the pair-wise relations more objective and accurate, the system structure deduced from these relations is more rational. After the theoretical foundation of GRA-based ISM is analyzed, its steps are depicted in details, followed by an empirical study on Beijing socio-economy system structure to prove its feasibility.
