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. 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 depa

ying for the honor of e*cellent graduation thesis. research e*perience 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 *is 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 e*periments, 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 applicat ……(未完,全文共4471字,當前僅顯示2258字,請閱讀下面提示信息。
