多层递阶方法在设备大修费用预测中的应用

The application of multi-layer hierarchical method in predicting equipment overhaul cost

采用相关系数法 ,确定了企业设备大修费用的主要影响因素。经标准化处理后 ,在确定时变参数估值的基础上 ,建立了大修费用多层递阶预测模型 ,并成功地实现了大修费用预测。

This paper adopted correlation coefficient method to define the main influence factors of equipment overhaul cost and all the variables were changed as standardized style to estimate the values of these time?based parameters. The Multi?layer hierarchical recursion model for equipment overhaul cost forecasting is successfully established in overhaul cost prediction.
