基于案例的舰船装备维修风险评估

Risk assessmet of ship equipment maintenance based on case

为提高船舶装备维修风险评估的可操性和正确性,首先分析了舰船装备维修中的风险问题,建立了基于案例的舰船装备维修单元任务风险推理模型;然后,引入神经规则,将案例知识转换成规则,进行风险评估的规则推理;最后,以某型柴油机为例进行了基于案例知识的维修单元任务风险评估。结果表明:基于案例的风险评估方法可以较大幅度地提高风险推理效率。

This article analyzes the risk problem in the ship equipment＇s maintenance, and builds a model of ship equipment＇s maintenance unit based on the Case reasoning task. Then, neural rules are introduced to convert case knowledge into rules to conduct the rules reasoning of risk assessment. At last, the example of some a diesel is given to demonstrate the usage of risk assessment of equipment maintenance based on case. The result shows that the given case risk validation method can significantly increases the efficiency of risk reasoning.
