中文摘要：	本文介绍了有关项目和项目管理的概念，定义，现代项目管理的主要发展，在制造业的应用以及我国现代项目管理的应用；阐述了设备整体效能理论。对设备整体效能进行了定义：设备整体效能，英文全称是：Overall Equipment Effectiveness，简称OEE。它由可用度、表现性、合格品率三个要素构成，单一设备甚至整个工厂的运行都受到OEE这三个要素累积效果的影响。由于半导体产业属于资本密集型产业，其设备投资庞大，运作成本高昂，使得投资者极为重视投资效益，不愿任何一台设备闲置而浪费产能，于是不断追求所有设备的完全利用，其绩效指标的追求除了交货期、在制品存量及周期时间外，还要求机台的使用率。由于高的设备利用率可以有效的降低生产成本，所以设备利用率就成为了半导体行业衡量生产水平的最重要的因素。 本文定义了项目的目标：将OEE水平从46%提高到56%项目时间：2006年1月至2006年12月；项目的成员以生产工程师和设备工程师为主。利用鱼骨图，头脑风暴方法得到了一个测试平台损失的瀑布图（Waterfall Chart），界定了损失的来源，从而明确了努力的方向，即改进的方向为精益生产，并形成了一系列的子项目和工作进度表。项目关注的方向为：通过批量的研究，得出合理的有利于整体设备效能提升的批量；利用单一作业转换方法和对时间研究，减少作业转换；通过实施全员生产维护和强化培训，一人多能进而改善管理方式；介绍了不良质量成本损失的概念，强化了六西格玛的实施，能过对产品测试进行量具有重复性与再现性分析，改善产品测试良品率；通过在组织内部推行自动生产排程，达到最合理的生产安排的效果。通过一系列的改善行动，最终完成了这一目标。这个项目的结果，标志着公司测试部门的OEE水平显著提高，项目的成功完成为公司节省了700万美金的投资。 本文的创新点在于：将项目管理的方法引入了生产运营管理领域，系统地提出了改善工厂设备整体效能的对策，这些对策具有一定的使用价值，希望能对生产运营管理实践有所帮助，对项目管理实践有所裨益。
英文摘要：	The thesis introduces the conception and definition of project and project management, and the future trends of project management. It also describes the OEE (Overall Equipment Efficiency) conceptions. OEE is based on Operating Rate / Availability, Performance Rate, and Quality rate. Any single equipment, even whole factory OEE will be impacted by the 3 elements multiplying effects. Semiconductor field is large capitalized industry; the equipment operating cost is quite high. The investors pay more attention to the investment effectiveness, reluctant wasting any capacity. Therefore, they pursue high equipment utilization. The performance indicator includes not only the OTD (On time delivery), WIP (Work In Processs) and cycle time, but also overall equipment utilization. Because higher utilization could result to a lower operating cost, the OEE is a major factor to measure the manufacturability. The project objective is to improve OEE from 46% to 56% during 2006 Q1 to Q4. The members are production engineers, equipment engineers. Team got a utilization waterfall through fish bone chart, brain storming, defined loss source, and cleared efforts, i.e. Implementing lean production with a series of sub-projects and work process timetable generated. The project focused on decreasing conversion time through lot size changing, SMED (Single Minutes Exchange of Dies) methodology implementation and time studying, improving management effectiveness through TPM, and multi-capable operators training; enhancing test yield by 6 Sigma GRR study; arranging production by system generates conversion model, not by material controller’s personal decision. Through a lot of actions and efforts, we met the management requirements, which could be seen from the waterfall one year later. The ending of this project represented that TJN factory got a significant improvement on J750 test manufacturing, but that is not to say it is the end of the continuous improvements. Any process could be improved if you have a continuous improving heart. The thesis does a superficial analysis on operation management with the employing of the project management methodology. It points out the practicable strategy to improve factory OEE. The strategy and analysis will help on the project management practice and operation management as well.
