基于检修运营数据的电网生产设备供应商优选方法

Optimization Method for Power Grid Production Equipment Suppliers Based on Maintenance and Operation Data

首先,构建适应多维目标的三级电网生产设备供应商评价体系,实现对成本、质量、服务水平、运营能力全面表征;然后,基于检修运营数据,运用层次分析法与CRITIC法,提出评价指标的主、客观权重计算方法,并结合最大信息量目标函数和Jaynes最大熵理论,建立供应商综合评价模型;最后,采用工程实际数据开展实证分析,揭示评价体系与方法的准确性、合理性,为电网设备供应商的综合排序与优选提供技术支撑,为保障电网设备安全稳定运行、提升设备资产价值奠定坚实基础。

This articlefirst constructing a three-level power grid production equipment supplier evaluation system that adapts to multidimensional objectives.Then,based on maintenance operation data,using AHP and CRITIC method,a subjective and objective weight calculation method for evaluation indicators is proposed.Combined with the maximum information objective function and Jaynes maximum entropy theory,a supplier comprehensive evaluation model is established.Finally,empirical analysis is conducted using actual engineering data to reveal the accuracy and rationality of the evaluation system and methods.The results can provide the comprehensive ranking and optimization of power grid equipment suppliers.
