针对电子装备试验周期的设计与优化,提出了基于未确知有理数的分析新方法.利用未确知有理数来描述和处理试验周期的不确定性,通过实例给出了其分析算法,使用确定性参数和未确知有理数2种方法对电子装备的试验周期优化进行了分析与比较.结果表明:基于未确知有理数的分析方法更好地考虑了参数的不确定性,可避免确定性参数描述的绝对化,从而使分析结果更加合理可信.%The new analysis method based on unascertained rational number is proposed for project and prediction of electronic equipment test period. The uncertainty of the test period is expressed by unascertained rational number and the analysis algorithm is introduced by the example. The electronic equipment test period is computed and analyzed by certainty method and uncertainty method. The comparison result shows that unascertained rational number can consider the uncertainty better of computation parameters and can avoid the absolutization of certainty expression. And the analysis result is more reliable and reasonable.
