摘要
输配电价改革后,电网企业精益化管理的需求提高,项目成本对投资决策产生直接影响,以往粗犷式的成本费用计算方法已不能满足当前需求。为此提出一种成本核算方法,该方法依据效能思想,对工程运行维护成本进行分摊计算。首先利用弹性网络算法对运行维护成本影响因素进行筛选,并确定关键因素效能标准;其次选取CRITIC(criteria importance though intercrieria correlation)方法进行权重测算,并获得单项工程的成本分摊系数,进而计算出工程的分摊成本,以实现工程运行维护成本的准确计量。最后选择中国某省典型工程数据对所提模型进行验证,结果表明,所提模型能够更精确地对电网工程运行维护成本进行计算。
After the reform of transmission and distribution price,the demand for lean management of power grid companies is increasing.The cost of a project has direct impact on investment decisions,so the traditional rugged cost calculation method cannot meet the current demands.To this end,a cost accounting method is proposed.In this method,according to the efficiency idea,the operation and maintenance cost of project is allocated and calculated.Firstly,the Elastic Net algorithm is used to screen the factors affecting the operation and maintenance cost to determine the performance standards of key factors.Secondly,the criteria importance though intercrieria correlation(CRITIC)method is used to measure and calculate the weight.The cost allocation coefficient of a single project is obtained,and then the allocated cost of the project is calculated to realize the accurate measurement of the operation and maintenance cost of the project.Finally,the typical project data of a province in China is selected to verify the proposed model.The results show that the proposed model can more accurately calculate the operation and maintenance cost of the power grid project.
