首先概括介绍了敏感性分析的一般内容，并给出了一种绘制敏感性分析图的简单方法，即利用数理统计的知识将因素变化量看成自变量，评价指标变化量看成应变量，然后回归成一元线型函数，就可在二维直角坐标系下作出敏感性分析图，通过这种简化的作图法，就可判断出强敏感性因素和弱敏感性因素，以及它们的敏感性程度。 First of all, the general content of sensitivity analysis is summarized, and a simple method of drawing sensitivity analysis graph is given. It uses the knowledge of mathematical statistics as the independent variable, the change of evaluation index as the dependent variable, And then return to a linear function of the linear, can be made in the two-dimensional Cartesian coordinate sensitivity analysis of the map, through this simplified mapping method, you can determine the strong and weak sensitivity of sensitive factors, and their sensitivity Sexuality.
