基于数据挖掘技术的充换电设施采购成本核算系统研究

Research on the Procurement Cost Accounting System of Charging and Changing Facilities Based on Data Mining Technology

为了提高充换电设施采购成本核算系统运行的准确性,减小系统成本核算结果与实际结果之间的偏差,开展基于数据挖掘技术的充换电设施采购成本核算系统研究。设计系统硬件设备,为系统运行提供良好的硬件环境;建立充换电设施采购信息数据库表,采集并存储成本核算数据;利用数据挖掘技术对充换电设施采购成本进行全方位的核算。系统测试结果表明,提出的成本核算系统应用后,充换电设施采购成本核算相对误差最大不超过0.2%,系统核算准确性得到了显著提升。

In order to improve the accuracy of the procurement cost accounting system for charging and swapping facilities and reduce the deviation between the system cost accounting results and actual results,we have introduced data mining technology and conducted research on a cost accounting system for charging and exchanging facilities procurement.Design system hardware equipment to provide a good hardware environment for system operation.Establish a database table for purchasing information of charging and swapping facilities,collect and store cost accounting data.Utilize data mining technology to comprehensively calculate the procurement cost of charging and swapping facilities.The system testing results show that after the application of the proposed cost accounting system,the maximum relative error in cost accounting for charging and swapping facilities procurement does not exceed 0.2%,and the accuracy of system accounting has been significantly improved.
