摘要
为了使各个设施的整体利用效果最佳,结合空间位置影响力查询技术,提出了基于RKNN的选址算法。针对空间对象对空间位置的贡献具有多重性,建立了一种新的空间位置影响力的度量模型,该模型更加符合实际应用情况;然后,利用该模型计算选址方案中各个设施的影响力,并引入均衡系数评价选址方案的合理性,均衡系数越小,方案越合理。实际应用表明基于RKNN的选址算法使村镇基础设施的选址更加合理、有效。
This paper proposed a location algorithm based on RKNN with the query for the influence of a spatial location in order to make the best use of all infrastructures. Subjecting to an object can make contribution to multiple locations, it proposed a new measure for evaluating the influence of spatial location, which met the actual applications. It used the new measure to estimate the influence of the village infrastructure. In the end, it used balanced coefficient to evaluate the reasonability of the location. The smaller the balaneed coefficient is, the more reasonability the program is. The actual application shows that the location algorithm based on RKNN makes the location algorithm more reasonable and available.
