| Abstract: | The drawbacks of the existing methods of solution with definite conditions for first order single sequence Grey Models (GM) are discussed and a solution with module definite conditions is proposed. It has been proved by examples that the accuracy of the model with the new method is significantly improved. The new method can also be used for GM (n, h)of n>1 or h>1 and other differential equation models containing random variables. |
