2. Samples do not need to be distributed regularly.

3, the calculation workload is small.

4. The results of quantitative analysis and qualitative analysis will not be inconsistent.

5. It can be used for short-term, short-term and long-term forecasting.

6. The grey prediction accuracy is high.

198 1 year, Professor Deng Julong, a cybernetic expert in China, first put forward the concept of grey system. Later, he published many papers and monographs on grey system and established the theory of grey system. Since 1982, grey system theory has been successfully applied to agriculture, industry, meteorology and other fields. Widely used in agriculture, geology, meteorology and other disciplines.

Grey prediction model application system;

The grey prediction model can be calculated by DPS data processing system and other calculation software. The English name of DPS data processing system is DPS. The system adopts multi-level drop-down menu. When users use it, the whole screen is like a working platform, which can be adjusted at will and operated freely. Therefore, it is vividly called DPS data processing platform, or DPS platform for short.

DPS platform is a universal multifunctional software system designed and developed by the author for mathematical statistics and mathematical model processing. It integrates the functions of numerical calculation, statistical analysis, model simulation, line drawing and tabulation.
