计及服务能力的配电网资产管理综合绩效评价方法
|
摘要
资产管理绩效评价是企业资产管理的重要环节,为改善我国配电网资产管理绩效评价体系,提出了一种新的配电网全寿命资产管理绩效综合评价模型。首先,通过深入分析我国配网发展特点和用户需求的差异性,以用户和配电网为分界面,构建了涵盖经济性、服务效能和社会效益等多方面的资产全寿命周期管理综合绩效评价体系。基于决策者偏好对极差变换的指标标准化方法进行改进;根据企业发展目标和各指标数据特点,运用兼顾主客观因素的最优组合赋权法,对服务效能和社会效益指标进行赋权。在此基础上,建立配电网资产管理绩效评价模型和计算方法。最后将该评价方法应用于某市级电力公司14个区县配电网的年度资产管理绩效评价,通过企业间横向对比、企业内纵向收益/成本分析,识别出管理的薄弱点,从而验证了方法的有效性。
Asset management performance evaluation is an important part of enterprise asset management.In order to improve asset management performance evaluation system of distribution network in China,a new performance evaluation model of life-cycle asset management is proposed.Firstly,development characteristics of distribution network and the various demands of consumers in China are thoroughly analyzed.A comprehensive performance evaluation system is constructed for asset life-cycle management covering economy,service efficiency and social benefits and other aspects with consumers and distribution network as the interface.Based on decision makers' preference,the normalization method of the range transformation is improved.According to the target of enterprise and the characteristics of each index,an optimal combination weighting method,which takes both subjective and objective factors into consideration,is used to weigh the service efficiency and social benefit indexes.Based on this,the performance evaluation model and calculation method are established.Finally,the evaluation method is applied to the performance evaluation of annual assets management of the distribution network in 14 counties of a municipal power company.By the horizontal comparison between enterprises and vertical benefit/cost analysis inside the enterprise,the weakness management is identified and the effectiveness of the method is verified.
