摘要
把城市噪声作为一个灰色系统,分别通过GM(1,1)模型和改进灰色系统模型GM′(1,1),对城市噪声进行预测,并进行精度检验。改进的灰色系统模型GM′(1,1)在精度上均优于GM(1,1)模型,但是GM′(1,1)在计算上比较复杂,需要通过计算机迭代来实现。
Taking the urban noise as a gray system, applying GM （ 1, 1 ） model and modified gray system model GM′（1, 1 ） predict urban noise separately and then verify their precision. Modified gray system model GM′（1, 1 ） is better than GM′（ 1, 1 ） model in precision, but the GM′（ 1, 1 ） model has some difficulties in calculating, computer is needed to realize repeatedly calculation.
