Grey optimal prediction model with weighted initial value
GM (1,1) model is one of the main contents of the grey prediction model, which reveals the inner law of development by the first-order differential equation of single variable for modeling and forecasting of a single time serie. For the initial conditions selection problem of original GM (1,1) model, the weighted average of x(1)(1) and x(1)(n) is given as the initial conditions. We obtain weights of x(1)(1) and x(1)(n) by AHP, and find the time parameterβ through a series of mathematical formula and gain the time responsive of improved model to improve the prediction accuracy.
