摘要
建立了管道腐蚀预测的基于小生境遗传算法灰色模型,将此预测模型应用于四川气田某输气管道的腐蚀速率和腐蚀深度的预测。预测结果表明,该模型的预测结果误差小,可以用于现场管道的腐蚀预测,是管道腐蚀预测的一种新方法。
The Niche GA-based gray model is established to predict the corrosion rate of natural gas pipeline. This model is applied to a gas pipeline in Sichuan province to forecast its corrosion rate and corrosion depth. The prediction results show that the relative errors predicted are less than the given references,and is a better model to predict the corrosion rate and corrosion depth of natural gas pipelines.
