Abstract

As initial value plays an important role in discrete GM model fitting accuracy, initial value of discrete GM model is selected by designing calculation program to reduce fitting error. Output results can show that the fitting equation of minimum relative error may pass through any point of 1-AGO series, and its fitting accuracy is better than that of traditional grey model and original discrete grey model. The calculating method has an application value.

设计计算程序选择离散GM模型初值

由于初始值对离散GM模型的拟合精度起着重要作用，因此通过设计计算程序选择离散GM模型的初始值，以减小拟合误差。输出结果表明，最小相对误差拟合方程可以通过1-AGO序列的任意一点，其拟合精度优于传统灰色模型和原始离散灰色模型。该计算方法具有一定的应用价值。

期刊介绍： The journal is a forum of the highest professional quality for both scientists and practitioners to exchange ideas and publish new discoveries on a vast array of topics and issues in grey system. It aims to bring forth anything from either innovative to known theories or practical applications in grey system. It provides everyone opportunities to present, criticize, and discuss their findings and ideas with others. A number of areas of particular interest (but not limited) are listed as follows: Grey mathematics- Generator of Grey Sequences- Grey Incidence Analysis Models- Grey Clustering Evaluation Models- Grey Prediction Models- Grey Decision Making Models- Grey Programming Models- Grey Input and Output Models- Grey Control- Grey Game- Practical Applications.
