A definition of accumulated generating operation in opposite direction is posed in this paper corresponding to traditional accumulated generating operation, gives a grey model GOM(1,1), provides a new generating method to grey modeling.
This text whose research object is clay-heart wall dam of JinPen water conservancy hinge, after counting the three dimensional nonlinear finite element, and analysis of prototype observation result, and the contrast analysis of the observation result and theory result, and the gray modeling analysis and prediction of observation data, has got relevant conclusions, and provides some gist for the dam' s safe operation.
The method of unify the time series analysis and the gray system theory to forecast the annual electric consumption is first to use the gray modeling or stepwise regression, obtain the mathematical model of tendency term from the data, then process the data that had been eliminated the tendency term with time series analysis, building ARMA model, then to unify the above two models to a combination model to forecast the annual electric consumption.
The works come to the conclusion that the gray modeling method has features of precision in prediction and requirement of less testing data, and is feasible to a real time testing of strain and stress intensity factors of stress concentration components.
