ua435
System dynamics created by professor Jay W. Forrester at MIT, is a field which bases on system theory, absorbs the quintessence of control theory, and draws support from computer simulation technique. Established by professor Deng Julong at Central China Institute of Science and Technology in 1982, grey system theory derives its idea and methodology mainly from control theory and operations research. Although system dynamics and grey system theory both have their own features in methodology and processing technique, there are still a lot of common points between them. From the comparative study on these two fields, the paper arrives at that it is not only necessary but also possible to infiltrate and draw on the experiences of each other to develop themselves.
