It is also used for the prediction of engineering mechanical and material scientific problems.
Introduction The gray prediction theory has been widely applied to the prediction of engineering mechanical problems.
A gray prediction model for unequal-interval time sequence Engineering geological data comprise usually unequal-interval time sequences.
Application Two engineering examples are listed below.

Study on the construction process control claims management Changbing Chen a , Duoci Wang b Department of Civil Engineering, Hefei University, Hefei 230022, China a ccbahhf@163.com, b wangduoci@163.com Keywords: Construction Project; Construction Claims; Management Abstract.
Engineering construction counterclaim occupy a very important position in the construction project cost management, is also a key part in engineering settlement audit.
Record material should include during the same time: event happens and actual conditions in the process, site personnel and idle list of equipment, time delayed, Engineering damaged degree, which lead to engineering cost increased, etc.
Specific formula is that the claim amount equals engineering practical total cost minus contract sum.
