灰色系统理论在管道完整性数据预测中的应用

根据管道完整性数据的不确定性、管道环境变化速度低、信息过去值发展受到的扰动少等特征,推荐采用基于趋势外推法的灰色系统理论预测管道完整性数据,提出了预测原则和预测对象分类等.介绍了预测数据序列生成步骤方法,给出了仅有一次检测数据的预测计算实例.

Application of Theory of Grey System on Forecasting the Pipeline Integrity Data

The trend extrapolation from theory of grey system to forecast pipeline integrity is recommended in this article,which is based on the uncertainty of integrity data of pipeline,low variety speed,of pipeline environment, little disturbed of data and other information,etc. Principle,classification and others to forecast the researched object are presented as well. The step and method of creating forecasting data series are also introduced,and a practical calculation example is given here which have detection data detected only once.
