Quantitative Analysis and Prediction of Power Grid Equipment Production Cost based on Stepwise Pegression Analysis

In order to meet the requirements of transmission and distribution price cost supervision and review, support the high-quality operation of modern equipment management system, strengthen the lean management of power grid equipment production cost and improve the overall asset operation performance, power grid enterprises carry out lean management of production cost. This study aims to measure the cost input-output and makes a comprehensive evaluation of the cost input-output of a power grid company from the dimensions of assets, safety, benefit and efficiency by using the regression analysis method. Then the quantitative relationship between cost and key factors is established to predict the future cost, which effectively cope with the pressure of future cost changes.
