舰船总体任务可靠性建模新方法

A New Method to Establish Reliability Model for Overall Mission of Ships

传统舰船总体任务可靠性建模方法难以全面反映舰船的实际任务,导致计算结果与实际相差较大。文章提出舰船单元任务的概念,确定舰船单元任务划分原则、单元任务的分类方法及任务的分解方法。基于单元任务改进传统的舰船典型任务剖面,提出新的舰船总体任务可靠性建模方法,并分析基于单元任务舰船总体可靠性模型的应用,示例表明了模型计算的可操作性。

The conventional way to establish the reliability model for the warship mission cannot fully match the actual mission. Consequently, the computing results differ greatly from the actual data. In this paper, the concept of unit mission was proposed and partition rules, classification methods and task assignments for each unit mission were established. Based on the proposed unit mission concept, traditional warship mission profile was improved and a new reliability model for the warship overall mission was presented. The new model was analyzed and examples demonstrated the operability of model computation.
