Weibull分布在航空武器项目经费管理中的应用研究

Study on Air-Borne Project Cost Management by Weibull Distribution

科学、合理的经费估算可以为项目立项与经费安排提供重要的决策参考;基于Weibull分布理论,首先提出了一种基于累计经费约束的最小二乘分布参数估计法,给出了几个常用的项目累计经费约束条件;其次运用提出的方法,对其在航空制导武器项目经费管理中的应用进行了研究;最后对应用情况进行了综合分析。

Scientific and appropriate cost estimating of project can be used in making important strategic decision for project application and project budget planning. Firstly, based on the Weibull distribution theory, a new least squares parameter estimating method that was based on total cost constraint and some common constraint conditions about total cost constraint of project were presented. Secondly, the article discussed the application in the air-borne project using the theory presented. Finally, a comprehensive analysis was summed up.
