摘要
研究了核电站核岛内外设备的不同维修策略、维修周期。建立了不同维修方法下的费用最小模型及可用度最大模型，为设备的合理维修给出了理论基础。
The maintenance tactics,the maintenance cycles and their difference for IE and NIE equipments in nuclear power station are studied.The minimum maintenance cost model and maximum availability model of eqiupments are developed.These give a theoretical basis for reasonable maintenance of the equipments.
