我们提出了一种新的技术来执行多端口系统的变异性分析。所提出的技术的多功能性使其适用于分析不同类型的现代电气系统（例如，互连，滤波器，连接器）。该方法在计算一组单变量宏模型的基础上，利用多项式混沌展开，得到包含其统计性质的多端口系统传递函数的宏模型。通过两个算例验证了该方法相对于经典蒙特卡罗分析的精度和显著的速度。
We present a novel technique to perform variability analysis of multiport systems. The versatility of the proposed technique makes it suitable for the analysis of different types of modern electrical systems (e.g., interconnections, filters, connectors). The proposed method, based on the calculation of a set of univariate macromodels and on the use of the polynomial chaos expansion, produces a macromodel of the transfer function of the multiport system including its statistical properties. The accuracy and the significant speed up with respect to the classical Monte Carlo analysis are verified by means of two numerical examples.
