针对传统GM(1,1)模型预测过程中参数固定导致适应性较差的问题,引入新陈代谢概念,给出了一种改进的新陈代谢GM (1,1)灰色预测模型；并应用于某型机载高度表中进行故障预测；结果表明与传统GM(1,1)预测结果相比,新陈代谢GM(1,1)预测结果与实际测试值间的绝对误差和相对误差均较小,预测精度也较高.%In order to resolve the poor adaptability of the fixed parameters in the traditional GM (1, 1) prediction, the metabolism was introduced and one improved GM (1, 1) model was proposed. It was applied to some airborne altimeter, and the results indicated that the absolute error and relative error between the predicted results and the actual measurement results of the metabolism GM (1, 1) were less and the prediction accuracy was higher than the traditional GM (1, 1) results.
