Hello!

I am a third year master major in automation at ×× University, P. R. China. With tremendous interest in Industrial Engineering, I am writing to apply for acceptance into your Ph.D. graduate program.

Education background

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,In 1999, I got the privilege to enter the graduate program waived of the admission test.

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 activityWhen a sophomore, I joined the Association of AI Enthusiast and began to narrow down my interest for my future research. 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. 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 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.

Thank you!

Datong is a city with a long history. As early as Palaeolithic age, there were ancient people living in this area. During the Warring States Period (476 BC - 221 BC), Datong region belonged to the Yanmen County of Zhao Kingdom. After Qin (221BC - 206 BC) unified the whole of China, the Great Wall was built west of Datong City. Datong got the name Pingcheng County that means peaceful city in Chinese because of years of harsh battle with the Hun. During the Northern and Southern Dynasties (420-589), Pingcheng was settled as the capital of Northern Wei Kingdom for 96 years and became ruinds at the year 526. After a long term of recovering, it became an important strategic county during Sui (581-618), Tang (618-907) and Five Dynasties (907-979). Liao Dynasty (916-1125) made Datong the auxiliary capital in 1044 and Jin (Kin) (1115-1234) retained it as a big city comprised of seven counties and three towns. During the Yuan Dynasty (1271-1368), Datong belonged to Zhongshu Province and had become a ’grandiose and beautiful city’ according to the description of the Italian traveler Marco Polo. In Qing Dynasty (1644-1911), Datong belonged to Shanxi Province and became Datong County during the domination of Republic of China. Datong was invaded by Japanese army in 1937 and became the capital of the so-called Northern Shanxi Self-Government. Finally in 1949, Datong was peacefully liberated.
