基于规程匹配的维修作业虚拟确认技术

Virtual validation technology of maintenance task based on task procedure matching

在建立了维修作业规程信息形式化模型的基础上,利用PAR语言将维修规程进行规范化描述,进而形成作业规程源案例库。采用混合相似度方法对模拟作业内容与源案例库规程进行相似度计算,将计算结果作为维修作业虚拟确认的判断依据,实现了维修作业规程指导虚拟维修仿真的目的。最后,通过实例证明了该方法的适用性和先进性。

The informalization model was presented to describe maintenance task procedure information.The task procedures were normatively described by PAR（parameterized action representation） so as to build a storehouse of source case for task procedures.The similarity between the mock task content and task procedures in the storehouse was computed by means of hybrid similarity method.The result can provide judgment rules for virtual validation of maintenance task.Therefore,the goal that task procedures directing virtual maintenance was realized.Finally,the method was proved to be applicable and advanced by an example.
