寿命服从极小值分布的MIS的软件可靠性分析

Reliability Analysis Made on MIS Software with an Operation Life Submitting to Minimum Distribution

在管理信息系统 (MIS)开发过程中 ,对 MIS软件进行截尾寿命测试 ,收集其故障数据 .应用可靠性统计方法 ,对寿命服从极小值分布的 MIS软件 ,建立最大似然方程的参数迭代法 .给出了各种可靠性指标公式 。

During the development of management information system (MIS), the MIS software is passed through a truncated life test and the data of its fault are collected. By applying the method of reliability statistics, a parameter iteration of maximum likelihood equation is set up for MIS software with an operation life submitting to minimum distribution. Various formalae of reliability index are given and verified by case computation.
