摘 要：
A combination forecasting algorithm based on gray model and cubic spline interpolation was proposed.Using this method to predict the data samples from non-isochronous, they belong to three different fields. The results show that : the proposed algorithm can more accurately predict the samples from non-equal interval, and simple, the accuracy of the predicted values are also higher than the literature. In the project, the proposed algorithm is more practical, and can be used in a variety of engineering fields.
