【摘要】：本论文研究的是硬盘生产阶段的可靠性工程项目管理，，它针对公司在硬盘生产可靠性管理方面存在的问题，提出了一系列的解决方案，研究硬盘生产可靠性项目管理的方法，包括关键路径法、项目进度管理法、挣值法等。对项目的完工时间和成本进行了控制，相比之前的管理方法，本论文提出的方法成功地为公司节省了10.11%的成本，即综合运用项目进度管理方法（包括关键路径法、设计结构矩阵法等）、挣值法对硬盘可靠性进行系统化的管理，提高了公司可靠性管理效率。另外还对提高硬盘平均可靠性寿命进行了方法研究，运用高等数学和管理统计学建立了硬盘寿命预测模型，即韦伯分布模型，并对决定模型的参数进行了研究和讨论，得出了控制和提高硬盘可靠性寿命的方法。运用失效分析的结果，采取措施减少硬盘早期失效率以及控制失效硬盘数目的方法，控制可靠性寿命分布的两个参数从而提高平均寿命。最后对方法进行了实践检验并进行了效益评估、对比。
[Abstract]:This paper studies the reliability engineering project management in the hard disk production phase. It puts forward a series of solutions to the problems existing in the hard disk production reliability management. Research hard disk production reliability project management methods, including critical path method, project schedule management method, earned value method, etc. The completion time and cost of the project are controlled, compared with the previous management methods. The method proposed in this paper has successfully saved the company 10.11% cost, that is, the comprehensive application of project schedule management methods (including critical path method, design structure matrix method, etc.). Earned value method systematically manages hard disk reliability and improves the efficiency of company reliability management. In addition, the method of improving the average reliability life of hard disk is also studied. The hard disk life prediction model, Webb distribution model, is established by using advanced mathematics and management statistics, and the parameters determining the model are studied and discussed. The methods of controlling and improving the reliability life of hard disk are obtained. By using the result of failure analysis, measures are taken to reduce the early failure rate of hard disk and to control the number of failed hard disk. Two parameters controlling the distribution of reliability life are used to improve the average life. Finally, the method is tested in practice and its benefit is evaluated and compared.
