The current major application fields of satellite positioning some of tropospheric refraction correction model are introduced.

A new correction model for the target deviation is deduced when the optical axis is not parallel to the collimating axis, and the coordinates of the camera projection center in measuring coordinate systems are calculated in conditions of the mismatching between the optical center and the theodolite rotation center by using the object focus optical system as the projective center of camera system.

A profit distribution correction model for EPC engineering supply chain based on Shapley value was proposed which makes the profit distribution more reasonable.

Study on structure finite element model updating based on response surface methodology;

Comparative research on methods of dynamic model updating of structure;

Application of genetic algorithm on structural finite element model updating;

Study on the ecological carrying capacity in mining city based on the modified model of ecological footprint;

A modified model in this work was presented based on the entropic free-volume model which was proposed by Elbro atc.

The modified model can sufficiently reflect the distributed parameter characteristic of thermal systems, and can also apply to research on both full scale real time simulation training system and control system simulation of power plant.

In feedback correction, considering the requirements of the accuracy and practicability, error compensation and model correction are adopted to correct the predictiv.

Evaluation method based on the model modification for the oil derrick;

Dynamic modeling and model modification of light bus body-in-white;

In compliance with the perturbation theory,the original optimization problem of model modification is converted into the solution of a series of optimization subproblems with their sensitivity not changed and the model modification for long span bridge can be therefore easily and simply implemented.
