基于模糊决策法的某型直升机航电系统原位检测设备需求评估
|
摘要
针对某型直升机航电系统外场维护过程中急需原位检测设备,但具体需求又不明确这一问题,采用模糊决策法对航电系统原位检测设备需求进行评估。在对航电系统分析的基础上,初步确定了航电系统的6个子系统原位检测设备需求评估,作为研究对象。通过专家评价给出系统自身原位检测设备需求影响因素,如复杂度、重要度等,同时结合外场故障数据的收集和分析,给出与维护工作直接相关的故障频率、故障严重度等影响因素的评分。在考虑各影响因素评价权重后得出各个子系统原位检测设备需求决策系数,对某型直升机航电系统原位检测设备的研制具有一定的参考价值。
Aimed at accurate and credible evaluating the requirements of helicopter's avionics systems in-situ testing equipment,the fuzzy decision method was proposed in this paper. Based on the analysis of avionics system,requirements evaluation of six sub- systems in-situ testing equipment was identified as the study object. The effective factors of requirement evaluation,such as complexity,importance,were determined by expert assessment. The grade of failure frequency and fault severity were determined based on the analysis of the field data. The requirements decision coefficients of every sub- system were obtained by considering the evaluation weight of every factor. It had a certain reference value for the development of helicopter's avionics systems in- situ testing equipment.
