应3044am永利集团3044noc姜歌东副教授邀请，美国Arizona 州立大学计算信息和决策系统工程学院工业工程系助理教授潘荣博士近日将来我院进行学术交流，并于12月21日、23日专程为我院师生做两次学术讲座。讲座的题目、时间地点及讲座内容分别如下：
题目一：Control Charts and Adjustment Strategies in
Statistical Process Control
(基于统计的过程控制中的控制图和控制策略)
时 间：2009年12月21日（周一）下午:3:00
地 点：3044am永利集团3044noc第三会议室
讲座人：潘荣博士
Abstract:
A manufacturing process is a stochastic process which is expected to keep a consistent quality level. However, unexpected events (assignable causes) can break the consistency and move the mean of quality characteristic to an unknown level at an unknown time. Control charts of statistical process control (SPC) are used to monitor the process and signal alarms if the process change does happen. In this talk, designs and properties of control charts that commonly used by quality engineers will be discussed. Meanwhile, it is noticed that control chart alone does not provide control actions or suggestions for correcting the process change. Several process adjustment strategies will be presented in this talk. The small-sample performance of integrating process adjustments with control charts will be compared through Monte Carlo simulation study.
题目二：Some Statistical Methods in Reliability
Engineering Research
(可靠性工程研究中的统计学方法)
时 间：2009年12月23日（周三）上午9:00
地 点：3044am永利集团3044noc第三会议室
讲座人：潘荣博士
Abstract:
Reliability engineers consider the time dimension of quality, i.e., the product or process quality over time. Like quality engineering, the research in the field of reliability engineering utilizes many statistical tools for modeling and data analysis. In this talk, I will discuss two topics from my recent research on accelerated life testing (ALT). The first topic is the data analysis of step-stress accelerated life tests. We formulate the problem through generalized linear models and provide a Bayesian analysis solution. The second topic is the experimental design problem of accelerated life tests. I will discuss the research motivation through a practical example, which highlights the complexity and difficulty of planning industrial ALT experiments. The optimal experimental design obtained based on a D-optimal criteria is compared with a legacy design and an ordinary orthogonal design. The research to be presented in this talk is supported by two NSF grants.
