GM（1，N）－2模型及其在机器运行状态预测中的应用

GM(1,N)-2 Model & Its Application to the Prediction of Machine status

根据现场特点，提出灰色非等间隔优化模型—ＧＭ（１，Ｎ）－２模型，对机器运行状态进行预测。并根据滨海轮的实测信号，对模型进行了检验。

According to reality,we submit an idea of unequal period optimized model GM(1,N)-2 with which to predict the status of machine,It does well while applied to signals of the BINGHAI vessel.
