I am a third year master major in automation at Shanghai Jiao Tong University, P. R. China. With tremendous interest in Industrial Engineering, I am writing to apply for acceptance into your Ph.D. graduate program.
In 1995, I entered the Nanjing University of Science & Technology (NUST) -- widely considered one of the China’s best engineering schools. During the following undergraduate study, my academic records kept distinguished among the whole department. I was granted First Class Prize every semester, and my overall GPA(89.5/100) ranked No.1 among 113 students. In 1999, I got the privilege to enter the graduate program waived of the admission test. I selected the Shanghai Jiao Tong University to continue my study for its best reputation on Combinatorial Optimization and Network Scheduling where my research interest lies.
At the period of my graduate study, my overall GPA(3.77/4.0) ranked top 5% in the department. In the second semester, I became teacher assistant that is given to talented and matured students only. This year, I won the Acer Scholarship as the one and only candidate in my department, which is the ultimate accolade for distinguished students endowed by my university. Presently, I am preparing my graduation thesis and trying for the honor of Excellent Graduation Thesis.
Research experience and academic activity，When a sophomore, I joined the Association of AI Enthusiast and began to narrow down my interest for my future research. In 1997, I participated in simulation tool development for the scheduling system in Prof. Wang’s lab. With the tool of OpenGL and Matlab, I designed a simulation program for transportation scheduling system. It is now widely used by different research groups in NUST. In 1998, I assumed and fulfilled a sewage analysis & dispose project for Nanjing sewage treatment plant. This was my first practice to convert a laboratory idea to a commercial product.
In 1999, I joined the distinguished Professor Yu-Geng Xis research group aiming at Network flow problem solving and Heuristic algorithm research. Soon I was engaged in the FuDan Gene Database Design. My duty was to pick up the useful information among different kinds of gene matching format. Through the comparison and analysis for many heuristic algorithms, I introduced an improved evolutionary algorithm -- Multi-population Genetic Algorithm. By dividing a whole population into several sub-populations, this improved algorithm can effectively prevent GA from local convergence and promote various evolutionary orientations. It proved more efficiently than SGA in experiments, too. In the second semester, I joined the workshop-scheduling research in Shanghai Heavy Duty Tyre plant. The scheduling was designed for the rubber-making process that covered not only discrete but also continuous circumstances. To make a balance point between optimization quality and time cost, I proposed a Dynamic Layered Scheduling method based on hybrid Petri Nets. The practical application showed that the average makespan was shortened by a large scale. I also publicized two papers in core journals with this idea. Recently, I am doing research in the Composite Predict of the Electrical Power system assisted with the technology of Data Mining for Bao Steel. I try to combine the Decision Tree with Receding Optimization to provide a new solution for the Composite Predictive Problem. This project is now under construction.
Besides, In July 20xx, I got the opportunity to give a lecture in English in Asia Control Conference (ASCC) which is one of the top-level conferences among the world in the area of control and automation. In my senior year, I met Prof.Xiao-Song Lin, a visiting professor of mathematics from University of California-Riverside, I learned graph theory from him for my network research. These experiences all rapidly expanded my knowledge of English and the understanding of western culture.
I hope to study in depth .In retrospect, I find myself standing on a solid basis in both theory and experience, which has prepared me for the Ph.D. program. My future research interests include: Network Scheduling Problem, Heuristic Algorithm research (especially in GA and Neural network), Supply chain network research, Hybrid system performance analysis with Petri nets and Data Mining.
Please give my application materials a serious consideration. Thank you very much.
我是上海交通大学自动化专业第三年，中国。我对工业工程学有着浓厚的兴趣，现写信向你的博士申请接受。研究生课程。
1995年，我进入了南京理工大学，被广泛认为是中国最好的工程学校之一。在接下来的本科学习期间，我的学习记录在整个部门中保持着卓越的地位。每学期我获得一等奖，我的整体GPA（89.5 / 100）在113名学生中排名第一。 1999年，我获得了入学考试免除的研究生课程的特权。我选择了上海交通大学继续我的研究，在我的研究兴趣在于组合优化和网络调度方面的最佳声誉。
在我的研究生阶段，我的整体GPA（3.77 / 4.0）排在前5％。在第二学期，我成了只有才能和成熟的学生的助教。今年，我获得了宏碁奖学金作为本系唯一的候选人，这也是我校赋予的杰出学生的最高荣誉。目前，我正在准备毕业论文，为毕业论文的荣誉而努力。
研究经历和学术活动，大二的时候，我加入了AI爱好者协会，开始缩小我对未来研究的兴趣。 1997年，我参与了王教授实验室调度系统的仿真工具开发。利用OpenGL和Matlab的工具，设计了一个运输调度系统的仿真程序。现在，NUST的不同研究小组已被广泛使用。 1998年，我承担并完成了南京市污水处理厂污水处理分析处理工程。这是我第一次将实验室的想法转化为商业产品的做法。
1999年，我加入了著名教授俞耿耿研究小组，针对网络流量问题的解决和启发式算法的'研究。不久我参与了FuDan基因数据库设计。我的职责是从不同的基因匹配格式中挑选有用的信息。通过对多种启发式算法的比较分析，介绍了一种改进的进化算法 - 多种群遗传算法。通过将整个种群划分为几个子种群，这种改进的算法能够有效防止遗传算法局部收敛，促进各种进化方向。它在实验中也证明比SGA更有效。在第二学期，我加入了上海重型轮胎厂的车间调度研究。调度是为橡胶制造过程设计的，不仅涵盖离散的而且连续的情况。为了在优化质量和时间成本之间取得平衡点，提出了一种基于混合Petri网的动态分层调度方法。实际应用表明，平均完工时间大大缩短。我也用这个想法在核心期刊上发表了两篇论文。最近，我在“宝钢数据挖掘技术辅助电力系统综合预测”中做了一些研究。我尝试将决策树和退回优化结合起来，为复合预测问题提供一个新的解决方案。这个项目正在建设中。
此外，20xx年7月，我有机会在亚洲控制会议（ASCC）上进行英语讲座，这是全球控制和自动化领域的顶级会议之一。在我大四的时候，我遇到了加州大学河滨分校的数学客座教授林小松教授，我从他的网络学习中学习了图论。这些经历都迅速扩大了我的英语知识和对西方文化的理解。
我希望深入研究。回想起来，我发现自己在理论和经验上都有坚实的基础，为我准备了博士学位。程序。我的未来研究兴趣包括：网络调度问题，启发式算法研究（特别是遗传算法和神经网络），供应链网络研究，Petri网混合系统性能分析和数据挖掘。
请给我的申请资料认真考虑。非常感谢你。
