灰色系统是由华东工学院邓聚龙教授1982年创立的。它对部分信息明确、部分信息不明确的系统的研究提供了新的基本理论和研究方法。农业病虫测报获得的仅是农田生态系统中全部病虫信息的很少一部份,有许多信息不明确,故研究农业病虫系统可以采用灰色系统的理论和预测方法。概率论是基于数据的统计规律来处理随机量。而灰色系统则是通过数据到数据的映射,时间序列到时间序列的映射来处理随机量和发生规律。含灰色元素的数学模型所描述的系统
The gray system was founded by Professor Deng Ju-long of East China Institute of Technology in 1982. It provides a new basic theory and research method for the systematic research of some information clearly and some of the information is not clear. Agricultural pest forecasting obtains only a very small part of the total pest information in the agroecosystem, and many of the information is not clear. Therefore, the research on agricultural pest system can adopt the gray system theory and forecasting method. Probability theory is based on the statistical laws of data to handle random quantities. The gray system is through the data to the data mapping, time series to time series mapping to deal with the random amount and the law of occurrence. The system described by the mathematical model with gray elements
