基于状态预测与评估的部件任务成功性评估研究

Evaluation of dependability of unit based on state evaluation and prediction

针对任务成功性评估的需要,充分考虑任务可靠性与维修性的特点.在状态监测与预测的基础上,通过D-S证据理论与模糊综合评判相结合的办法得出部件针对任务的不可靠度,由不可靠度与相关维修数据相结合来实现对部件的任务成功性评估.最后通过示例应用表明了该方法的可用性.

For the need of dependability evaluation, we give full consideration to the characteristics of reliability and maintainability. Through D-S evidence theory and fuzzy comprehension assessment, we arrival at a conclusion of unreliability based on the state monitoring and forecasting. We combine with unreliability and the related maintenance data to achieve the evaluation of dependability of unit. Finally, the applicability of the method was validated by an example.
