基于集合覆盖模型的电费缴纳点选址研究

Site Selection of Electricity Office Based on Set Covering Model

在大营销体系下,各省市电力公司都在倾力打造"10分钟缴费圈",为电力用户提供方便、快捷、多样化的电费缴纳方式。在分析国内现有电费缴纳方式的基础上,构建了基于"10分钟缴费圈"的电费缴纳点选址集合覆盖模型,同时以各种电费缴纳方式的费率为权重,提出了带权的集合覆盖模型。通过对甘肃省兰州市安宁区电费缴纳点和现有的居民小区的地理位置进行分析,运用LINDO软件对建立的集合覆盖模型进行优化求解,证明了该模型的可行性。该模型可以帮助各地区选择合适的电费缴纳合作伙伴,以最小的投资成本获得最大的用户满意度。

In the context of extensive marketing system, the provincial and municipal power companies are making efforts to implement the idea of ＂Electricity payment within ten-minute walk＂ in order to provide fast, convenient, and diversified bill payment methods. Based on the analysis of the existing domestic and foreign electricity payment methods, a set covering model of site selection for electricity payment office based on the idea is established. In addition, a weighted set covering model that takes the electricity payment rates as weight is built at the same time. By analyzing the locations of electricity payment offices and the neighbourhoods in Anning District of Lanzhou, Gansu Province, the optimization and solution of the set covering model is carried out with the LINDO software, which proves the feasibility of the model. The result indicates that the model can help all regions to select the appropriate electricity payment partners to maximize the user satisfaction with minimal investment cost.
