摘要: 任务可靠性的评价是武器装备研制生产过程中的重要工作内容,任务阶段的FMECA评价多从定性的角度进行,未考虑故障模式影响程度的定量指标。基于模糊数学思想,结合FMECA分析中的故障模式影响概率,形成FFMECA分析方法;并在此基础上,将那些影响任务完成的故障模式以定量的形式进行区分,进行考虑故障模式影响概率的任务可靠性评价,并以可撒布地雷为例开展了任务阶段的定量与定性分析。结果表明:本文方法紧密结合可靠性前期工作,对武器装备可靠性评价流程进行了规划,对可靠性评价方法的工程应用具有一定的指导意义。

Abstract: Mission reliability assessment is an important part of the process of weapon equipment development and production, and the assessment of FMECA in the attack mission stage has been made mostly in the qualitative aspect without consideration of the quantitative index of the degree of failure mode effect. In this paper, based on the fuzzy mathematics, the probability of failure mode effect is defined and given in the FMECA, and FFMECA method is formed. Based on this, the failure modes that affect the success of the mission are distinguished in the form of quantification, and the mission reliability is assessed with consideration of the probability of failure mode effect. The scatterable landmine is analyzed qualitatively and quantitatively in the attack mission stage. The results show that the method closely combines the early work of reliability, plans weapon equipment reliability assessment process, and is significative to engineering application of reliability assessment method.

Key words: mission reliability assessment, failure effect probability, FFMECA analysis, scatterable landmine, quantitative and qualitative analyses
