基于Markov决策过程的舰船燃气轮机运行与维护成本建模

Operation and Maintenance Cost Modeling of Marine Gas Turbines with the Markov Decision Processes

针对燃气轮机性能退化特性和维护保养策略分析,考虑机组的随机故障失效和退化失效,运用Mark-ov决策过程方法,提出了基于状态的燃气轮机运行与维护成本模型。通过算例分析,验证了模型的可行性,并比较了三种不同保养策略的可用度和经济性。

Based on performance deterioration and maintenance-policies analysis of gas turbines,an condition-based operation and maintenance cost model is presented with the Markov decision processes.Random failures and failures due to deterioration are considered.An example is used to illustrate the implementation of the model.The availability and operation and maintenance cost of gas turbine are compared under three different maintenance policies.
