摘　　要：为科学安排船舶维修级别,提高船舶的运用效率,降低船舶维修费用,借鉴装备维修级别分析方法,引入概率理论,并以维修费用期望值最小为目标函数,建立了船舶维修级别经济性分析决策树模型.基于该决策树模型,设计了不同级别的维修费用与维修成功率之间的关系图,直观表达最佳维修级别范围.通过一个简化维修算例,说明使用该方法确定船舶设备维修级别的基本原理及其合理性.To select the best level for ship repair, enhance the efficiency of using ships and reduce ship repair costs, a decision tree model has been built for economic analysis of ship repair levels. The model taking the minimum expected repair costs as objective function is based on the analysis of repair level for military equipment and on the probability theory. A decision chart that reflects the optimal ranges of different levels of repair for a given task has also been worked out to assist the understanding of the model. Finally, a simplified example is presented to illustrate the fundamental and validity of the model.
