Then taking Jinji(Tianjin—Jixian) Highway of Tianjin as an example,the errors of system simulation are tested,and the system dynamics model built is verified to be quite stable,which has a high performance. Through the comparison of simulation results with and without Jinji Highway,the paper simulates and predicts the socio-economic benefit of each year from 2003 to 2013. Thus the quantification evaluation of socio-economic benefit of highway project is realized and will provide the theory instructions for similar projects in the future.展开更多

And the impact factors on the credit classification of the practicing qualification personnel,such as the number of neurons,the training steps,the dimension of neurons and the field of winning neurons are studied. Then a self-organizing competitive neural network is built. At last,a case study is conducted by taking practicing qualification personnel as an example. The research result reveals that the method can efficiently evaluate the credit of the practicing qualification personnel;thus,it could provide scientific advice to the construction enterprise to prevent relevant discreditable behaviors of some practicing qualification personnel.展开更多
