A method of system structural analysis based on decision making trial and evaluation laboratory together with interpretative structural modeling (DEMATEL-ISM) and entropy is proposed to clarify system structure of communication networks and analyze mutual influencing degree between different networks. Mutual influencing degree and importance degree of elements are both considered to determine weights of elements, and the entropy of expert judgment results is used to omit unimportant influence relation and simplify system structure. Structural analysis on communication networks system shows that the proposed method can quantificationally present weights and mutual influencing degree of elements, and reasonably simplify system structure. The results indicate the rationality and feasibility of the method.
