In order to evaluate the survivability of networked information system effectively, this paper presents a method of combining grey relation analysis and TOPSIS for quantitative assessment. Firstly, a hierarchical model of information system is constructed. Then it normalizes indicator matrix according to traditional TOPSIS method, determines the positive and negative ideal solutions, calculates the optimal dependency degree of critical services in terms of grey relation analysis, and evaluates the whole networked information system depending on the survivable function. At last this paper gives an example to show the availability and the value of the method.
