e 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 posite predict of the electrical power system assisted with the technology of data mining for bao steel. i try to bine the decision tree with receding optimization to provide a new solution for the posite predictive problem. this project is now under construction. besides in july 2000 i got the opportunity to give a lecture in english in asia control conference (ascc) which is one of the toplevel conferences among the world in the area of control and automation. in my senior year i met prof. xiaosong lin a visiting professor of mathematics from university of californiariverside 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 . 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.
