| Abstract: |
| 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. |
