备件可靠性分析及需求预测

摘要

针对备件需求量确定难的问题，采用可靠性分析法，提出了设备寿命服从多种分布的分布参数估计和未知寿命分布设备的寿命分布假设检验方法，建立了不同寿命分布设备备件需求量的预测模型，编制了装备备件保障软件，可方便、准确预测备件需求。%According to the difficulty of spare part ’s determination,this paper proposed method of distribution parameter estimation for equipment which the life submits many distributions and hypothesis testing method for equipment which life distribution unknown by using reliability analysis. It built the forecast model of the spare part requirement of equipment which the life submits different distribution,and made the software of weapons spare part support,which makes the spare part’s prediction become more exact and easier.
