Abstract: In some real complex networks, to maximize interests and minimize their own risk, networks managers will face making some decisions, but the existing researches are against a kind of network to making-decision, and lack of versatility, also ignore a large number uncertain phenomenon in complex networks, it is difficult to obtain good decision. This paper defines network-based of rough complex networks, studies the natures of network-based, and proves the conclusion of complex network equivalent its network-based. Then this paper proposes two decision methods about nodes importance and decision methods of rough complex networks based on network-based. Finally this paper uses the decision methods based on network-based in the risk decisions of the third-party payment rough complex networks, establishes a risk decision model, and gives quantitative decision results. The decision methods based on   network-based are used successfully in the risk decision model of the third-party payment rough complex networks, which show the effectiveness and feasibility of decision methods.

Key words: rough complex networks, network-based, decision methods, the third-party payment risk analysis
