摘　　要：电子万能试验机工作时,各影响因素之间存在模糊灰色特征,采用传统的评价方法很难对其进行精确的评价。因此,需要选用一种合适的方法对其进行有效的评价。本文利用模糊灰色理论,以电子万能试验机系统作为对象,构建了可靠性评价模型,并与测试的试验数据结果进行对比。对比结果证明,该方法具有评价过程简单、评价准确等特点,特别是针对模糊灰色多因素问题的评价,该方法更具科学性。There are some fuzzy relationships between all the influencing factors of working elec- tronic universal testing machine, and it is hard to get a proper estimate with the traditional meth- od. So a better way is needed. In this paper, a reliable model is established for the evaluation based on the fuzzy grey theory, which is proved to be simple and precise by the test data. And this method also shows its remarkable advantage in the evaluation of the fuzzy grey multi-factor.
