By recognition of work condition, off-line identification and on-line optimization of parameters, hybrid model can be used to simulate dynamics of complex process correctly in a large scale.

And it introduced the AHP to the optimization process of he clamp conceptual design (AHP), on the basis of a series of optimization guide line, we could select the best project from lots of projects.

The paper introduces an on-line self-learning optimization algorithm , and its application on the catalytic cracking process.
