The basic properties of the importance measure of the basic variable effect on the failure probability are discussed in this paper. Since the saddlepoint based line sampling method is independent of the distribution types of the random variables, and has the advantages of high accuracy and efficiency, this method is employed to estimate the defined importance measure.
