Chapter 4 and chapter 5 are about simulation methodology. In chapter 4, the design idea and techniques of implementing intelligent simulation of dam concrete placement system are clarified and the simulation research method of separating experiments from models is introduced. On the basis of the research, the simulation function structure frame of dam concrete placement system is constructed, which makes the simulation software system of dam concrete placement become a general-used and intellectualized simulation study environment in which simulation modeling, experiments and analysis are integrated.
