Through the limitations of current evaluation about the network storage system survivability,a quantitative evaluation method based on grey relation analysis is proposed.The typical gray relation analysis method is improved and the quantitative evaluation model based on the network entropy of information is established.The change of every key service's survivability situation is assessed by using the network entropy of information.The established network storage system is run to test method of grey relation analysis,and the calculating result indicates that the proposed method can effectively evaluate the actual survivability of the network storage system.
