装备维修保障知识模型构建及推理方法

Construction and Reasoning Method of Equipment Maintenance Support Knowledge Model

针对装备领域维修保障知识利用效率低、经验知识转化不足、故障定位分析困难等问题,提出了一种装备维修保障知识模型构建及推理方法。首先,通过对装备维修保障工作流程、知识构成及知识特征的分析,借助知识的本体表示方法,设计装备维修保障知识模型,并结合具体装备给出知识模型构建方法;其次,基于知识模型并综合考虑人员经验性知识的量化表达,提出故障原因可信度推理方法,实现维修知识的有效推理计算;最后,以车辆装备发动机故障为例,验证了所提方法的可行性,为装备领域维修保障知识模型构建和推理应用提供借鉴。

Aiming at the problems of low utilization efficiency of maintenance support knowledge in equipment field,insufficient transformation of experiential knowledge and difficulty in fault location analysis,an equipment maintenance support knowledge model construction and reasoning method was proposed.Firstly,through the analysis of equipment maintenance support workflow,knowledge composition and knowledge characteristics,with the help of knowledge ontology representation method,the equipment maintenance support knowledge model is designed,and the construction method of knowledge model is given based on specific equipment.Secondly,based on the knowledge model and considering the quantitative expression of personnel’s experiential knowledge,a fault cause credibility reasoning method is proposed to realize the effective reasoning calculation of maintenance knowledge.Finally,the feasibility of the proposed method is illustrated by an example of vehicle engine failure,which can be used as a reference for the construction and reasoning application of maintenance support knowledge model in equipment field.
