摘要
基于未确知理论,定义了系统不确定性的一个度量尺度——盲数方差.通过将系统“宽区间”范围的“强”不确定性离散化处理成“窄区间”范围的“弱”不确定性,给出了基于盲数的系统不确定性数值计算原理和方法.它是一种通用的数值计算方法.实际计算表明该方法的正确性和实用性.
Based on the uncertainty theory, a measurement scale of uncertainty - blind number variance is defined. By dispersedly transforming the strong uncertainty in a wide interval into the weak uncertainty in a narrow interval, the numerical calculation principle and method of system uncertainty are also given. This is an all-purpose numerical value calculating method that is based on the blind number. Its correctness and practicability is perfectly proved by practical calculations.
