【摘要】 针对槽式光热系统中太阳能集热器、传热介质管道及换热器等关键设备，采用失效模式、影响与危害分析（FMECA）方法识别其失效模式、原因及后果。通过引入基于Z数的模糊集理论和Z-AHP方法，改进专家意见聚合过程，优化风险因子权重计算，最终得出设备失效模式的风险排序，并提出相应的管理和优化措施，提升了系统的可靠性和安全性。更多还原

【Abstract】 The failure mode, effect and hazard analysis(FMECA) method was used to identify the failure modes, causes and consequences of the key equipment like solar collector, heat transfer medium pipe and heat exchanger in the parabolic trough optothermal system. Through introducing the fuzzy set theory, Znumber and Z-AHP method, the improved expert opinion aggregation process and weight calculation of the risk factor, the risk ranking of equipment failure mode was finally obtained, and the corresponding management and optimization measures were presented to improve both the reliability and safety of the system.更多还原
