Table 3 Primary research methods for determining SC process parameters

Fully experimental

Physical experiment

Finding optimal parameters via control variable method

Too many experiments, expensive

Numerical simulation

Too many experiments, inexpensive

Modeling and optimization based on experimental data

Obtaining and optimizing experimental data using data-mining technology

Reliability of results depends on sample data, but amount of sample data is small

Establish empirical formulas

Establish design criteria or empirical formulas of process parameters according to the process

For certain types of casting, and the error is usually large
