Applying the reciprocal accumulated generating and the reconstruction method of GRM1,1 model’s background value of non-equidistant sequence based on the exponential trait of grey model and the definition of integral for the problem of lower precision as well as lower adaptability in non-equidistant GM1,1 model, the calculation formulas were deduced and a novel non-equidistant GRM1,1 model generated by reciprocal accumulated generating was put forward. The grey GRM1,1 model can be used in non-equidistant interval & equidistant interval time series and has the characteristic of high precision as well as high adaptability. Example validates the practicability and reliability of the proposed model.
