Simulated model was combined with optimization technique and self-optimization simulation was adopted based on the principle and method of system science.

Compared with conventional simulation methods, self-optimization simulation technique is more ideal for application in the beneficial purpose regulation and operation of a single reservoir or multiple reservoirs,and easier to computer programming.

A self-optimization simulation model is sct up for the water optimal dispatching of interbasin water transfer engineering and the satisfactory results are obtained in the optimization decision study of South-to-North water transfers.

This paper studies the optimal operation models of water resources of the middle route scheme of South to North Water Transfers with a mixed simulation method of large scale system, which is based on self optimal simulation technique and operation map of Danjiangkou reservior, the analysis of the calculation results shows that the model and the program are feasible and practical.

CEA and its application in simulation and optimization of chemical process;

The quantitative simulation and optimization of operation of the Harbin Taiping WWTP in winter were carried out by using the intelligent software based on the wastewater treatment model,namely operation decision support system(ODSS) for municipal WWTP.

The mathematical model and the software system for the process simulation and optimization of medium urea synthesis installation are described.
