general introduction
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.
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.
in 1999, i joined the distinguished professor yu-geng xi's 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.
