摘要
根据指数分布、正态分布和威布尔分布的寿命分布类型,对航海装备的一些维修备件进行分类,并提出了在满足备件保障度下这三种寿命分布类型备件的需求计算模型,对一些备件需求预测实例进行了预测计算。
The maintenance spare parts of nautical equipment are classified according to the types of life distribution including exponential distribution,normal distribution and Weibull distribution,and then three models to calculate the demands for the three types of spare parts are established respectively under the condition of satisfying spare availability.Several numerical experiments are designed to validate the effectiveness of the models for demand forecasting of maintenance spare parts.
