| 英文摘要 | Abstractuncertainty and randomness are two basic types of indeterminacy. chance theory was founded for modeling complex systems with not only uncertainty but also randomness. as a mixture of randomness and uncertainty, an uncertain random variable is a measurable function on the chance space. it is usually used to deal with measurable functions of uncertain variables and random variables. there are some important characteristics about uncertain random variables. the expected value is the average value of uncertain random variable in the sense of chance measure and represents the size of uncertain random variable. the variance of uncertain random variable provides a degree of the spread of the distribution around its expected value. in order to describe the variance of uncertain random variable, this paper provides some formulas to calculate the variance of uncertain random variables through chance distribution and inverse chance distribution. several practical examples are also provided to calculate the variance for through chance distribution inverse chance distribution. |
