CMM认征是软件企业走向标准化，提高竞争力的行之有效的途径。但仅有CMM是不够的，必须与PSP相结合。PSP是一种可用于控制、管理和改进个人工作方式的持续自我改善过程，是一个包括软件开发表格、指南和规程的结构化框架。推广PSP需要以认真的实践为基础，井努力总结亲身经历的经验和教训。 相似文献

为了分析协同式自适应巡航控制(CACC)车组的稳定性影响,构建了混合交通流条件下协同式自适应巡航控制车辆组引导车模型(LCACC).考虑协同式自适应控制车组间的信息交互延误,采用频域变换的方法来推理引导车模型的稳定性边界条件.将美国NGSIM数据库轨迹数据作为初始输入,根据先前研究成果,采用IDM模型模拟混合交通流中人工驾驶车辆的驾驶行为,运用环道测试的方法来验证引导车模型的稳定性.环道测试结果表明,LCACC模型在改善协同式自适应车组的稳定性方面有一定的优越性,敏感性分析显示CACC车组的大小对LCACC模型参数产生影响. 相似文献

An Assessment of Statistical Process Control-Based Approaches for Charting Student Evaluation Scores
Xin Ding Don Wardell Rohit Verma 《Decision Sciences Journal of Innovative Education》2006,4(2):259-272
We compare three control charts for monitoring data from student evaluations of teaching (SET) with the goal of improving student satisfaction with teaching performance. The two charts that we propose are a modified p chart and a z‐score chart. We show that these charts overcome some of the shortcomings of the more traditional charts for analyzing SET data. A comparison of three charts (an individuals chart, the modified p chart, and the z‐score chart) reveals that the modified p chart is the best approach for analyzing SET data because it utilizes distributions that are appropriate for categorical data, and its interpretation is more straightforward. We conclude that administrators and faculty alike can benefit by using the modified p chart to monitor and improve teaching performance as measured by student evaluations. 相似文献

Chocolate chip cookies are used to illustrate the importance and effectiveness of control charts in Statistical Process Control. By counting the number of chocolate chips, creating the spreadsheet, calculating the control limits and graphing the control charts, the student becomes actively engaged in the learning process. In addition, examining and interpreting the control charts within the context of the cooking making process encourage the student to think critically in order to solve problems. 相似文献

与传统的频率变换器相比,矩阵变换器能够实现功率的双向流动,驱动电机四象限运行,输入端功率因数可调节为1,输出电压幅值、相位和频率可独立调节等优点。由于矩阵变换器的一般控制算法为开环控制,使当输入存在干扰时,输出电压的质量就会受到影响。采用一种基于电压滞环控制的闭环控制策略,对电压进行闭环控制,并在Matlab环境下建立仿真模型,仿真结果表明该控制算法是可行和有效的。 相似文献

This paper describes the process employed by the Industrial and Management Systems Engineering programme at Kuwait University to continuously improve the programme. Using a continuous improvement framework, the paper demonstrates how various qualitative and quantitative analyses methods, such as hypothesis testing and control charts, have been applied to the results of four assessment tools and other data sources to improve performance. Important improvements include the need to reconsider two student outcomes as they were difficult to implement in courses. In addition, through benchmarking and the engagement of Alumni and Employers, key decisions were made to improve the curriculum and enhance employability. 相似文献

This paper will show how tools of statistical quality control were applied to a Summer Bridge Mathematics and Science programme at San Jose State University. These tools were used as assessment instruments to facilitate improvement in overall classroom performance. We shall show how quality control tools such as brainstorming, Pareto analysis and cause-and-effect analysis can be used to identify the ‘big’ problems and to analyze the cause(s) of the ‘big’ problems. Additionally, we shall show how control charts can be used effectively to monitor how the suggested corrective actions for causes of the ‘big’ problems are faring—or acting—on the outcomes-based process. Finally, we shall show how these control charts can be used to aid in monitoring and determining whether or not the ongoing outcomes-based process is stable. Once the ‘big’ problems have been eliminated and the ongoing process is in control, we shall further demonstrate how ‘monitored assessments’, cooperative learning activities and control charts can help to improve the overall process. 相似文献

In this paper, a method for analyzing data from student evaluations of teaching is presented. The first step of the process requires development of a regression model for teacher's summary rating as a function of student's expected grade. Then, two‐sigma control charts for individual evaluation scores (section averages) and residuals from the regression model are used to identify both excellent and poor outcomes. The performance of an individual whose scores are out of control on both charts cannot be explained by expected grade and therefore is worthy of note. 相似文献

Methods of statistical process control were briefly investigated in the field of educational measurement as early as 1999. However, only the use of a cumulative sum chart was explored. In this article other methods of statistical quality control are introduced and explored. In particular, methods in the form of Shewhart mean and standard deviation charts are introduced as techniques for ensuring quality in a measurement process for rating performance items in operational assessments. Several strengths and weaknesses of the procedures are explored with illustrative real and simulated rating data. Further research directions are also suggested . 相似文献
