Based on the chain rule techniques, AD seeks first or higher order derivatives of functions represented by a group of dependent program procedures and extended files, the so-called original model, through a number of code-to-code transformings under a series of differential rules.

基于链式求导法则的自动微分方法通过改写原程序模式代码，依赖机器自动构造不同的微分模式，来分析求解函数的一阶或高阶导数，即在一系列预定微分规则下对不同程序对象做从代码到代码的自动微分转换。

In presented method, the correlated variables are transformed into uncorrelated variables equivalently, and the performance functions in the correlated variables space are transformed into those in the equivalent uncorrelated variables space, in which the reliability sensitivity of the system failure probability with respect to the distribution parameters of the uncorrelated variables can be solved by the moment method for the uncorrelated variables. Finally the equivalent relationship between the correlated variables and the uncorrelated variables, the chain rule for derivative are employed to obtain the reliability sensitivity of the system failure probability with respect to the means of the correlated variables.
