摘　　要：提出基于效能-成本及灵敏度分析的二次设备优化运维模型。建立二次设备综合效能评估指标及计算模型,并对各效能影响因子的灵敏度进行分析。对二次设备的全生命周期成本模型进行修正,并进行灵敏度分析,确定高灵敏度成本指标。根据效能评估结果和成本容忍度,提出二次设备基于效能-成本的运维优化决策判据。通过测控装置算例分析验证了效能评估模型及灵敏度分析模型的可行性,并对优化运维策略进行估算,设备的经济性明显提高。An optimal operation-maintenance model based on efficiency-cost sensitivity analysis is proposed for the secondary equipment. The comprehensive evaluation indexes of the secondary equipments are proposed,their calculation models established,and the sensitivities of their influencing factors analyzed. The LCC（Life Cycle Cost） model of secondary equipment is modified and the sensitivity analysis is carried out to determine the costs with high sensitivity. The criteria of operation-maintenance optimization based on efficiency evaluation and cost tolerance are proposed for the secondary equipments. Example analysis for the measuring ＆ control equipment verifies the effectiveness of the proposed efficiency evaluation model and sensitivity analysis model. The economy of the optimized operation-maintenance strategy is estimated and obviously improved.
