摘要
电力管线入地敷设在城市电网建设和改造中得到大规模推广,合理的线路管廊入廊费用定价机制对促进线路管廊的建设与发展具有重要意义。现有收费机制在计算分摊系数时存在缺陷,鉴于此,提出了一种基于灰色群组聚类和客观赋权法(CRITIC)组合赋权的费用分摊模型。基于受益方付费原则确定入廊各方的费用分摊指标,分别采用灰色群组聚类和CRITIC计算各分摊指标的主观权重系数和客观权重系数,综合考虑指标权重的主客观信息,基于离差平方和方法计算各分摊指标的组合权重。将该模型应用于某线路管廊入廊费用分摊案例,验证了所提方法的有效性。
Underground laying method is recommended in municipal grid construction and upgrading,and reasonable pricing mechanism for the pipelines'utility tunnel entering cost is significant to the utility tunnel construction.The existing charging mechanism is flawed in allocation coefficients'calculation.Thus,a cost allocation model based on grey group clustering and CRITIC combined weighting is proposed.First of all,the cost-sharing indicators of all parties entering the tunnel are determined based on the principle of beneficiary payment.Then,the subjective weight coefficients and objective weight coefficients of different apportionment indexes are calculated based on grey group clustering and CRITIC,respectively.Finally,considering the subjective and objective weighting data,the combined weight of each apportionment index is calculated based on the sum of squares of deviations.The proposed model is applied to a pipelines'utility tunnel entering cost allocation scheme,and the case study verify the effectiveness of the proposed method.
