nt. the scheduling was designed for the rubbermaking 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 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 constructio
