composing frame
2.Following the technique frame of HLA, the characteristic and function of the platform were analyzed, based on which, its block composing and role of each block were introduced, and then the frame, flow chart and FOM/SOM (Federation Object Model/Simulation Object Model) of federation were given, and the implementation process of its federates was explained at last.
4.This paper studies the connotation,characteristics,strategic aim,frame composing ,implementing countermeasure,construction of demonstrated project and the signif icance of information civil engineering. In addtion,the paper gives the general s trategic scheme of information civil engineering. The implementation of informati on civil engineering will advance the construction technology and management lev el of civil engineering,and will cause the formation of information civil engine ering industry.
