【摘要】 在某型跨超声速风洞增量引射器维修方案评价过程中,针对维修方案评价指标的模糊性,建立了维修方案模糊评价模型,并给出了评价置信度的计算方法。利用建立的模型,对某型跨超声速风洞增量引射器4个维修方案进行安全性、经济性、拆卸装配性、人素工程、时效性、维修质量6个指标的定性与定量分析,得出了最优维修方案。文中所建立的数学模型也可对风洞其他系统的维修方案进行评价,以确定最优维修方案,从而提高风洞其他系统维修方案评价的科学性。更多还原

【Abstract】 A fuzzy evaluation model is proposed for the fuzziness of evaluation indexes of maintenance schemes in the maintenance scheme evaluating process of a trans-supersonic wind tunnel augmentation ejector,and the calculation method for evaluating confidence index is concluded. This model is used to qualitatively and quantitatively analyze 4 maintenance schemes in terms of safety,economics,disassemblability and assemblability,human factors engineering,timeliness,and maintenance quality,and the optimized maintenance scheme of the trans-supersonic wind tunnel augmentation ejector is obtained. At the same time,the maintenance schemes of other wind tunnel systems are also able to be evaluated to confirm the optimized maintenance schemes with this model,which promotes scientific nature of choosing optimal maintenance schemes.更多还原
