摘要：
Randomness and fuzziness are two basic types of uncertainty. However, a lot of surveys showed that some kind of uncertainty cannot be modeled by randomness nor fuzziness. So in this paper, the states of components and systems are considered as uncertain variables. Then the uncertain coherent system is defined and its structural properties are proposed. Moreover, the dual of uncertain coherent system is introduced and some useful theorems are given. Finally, the reliability of uncertain coherent system is arrived and some examples are given.
