【摘要】 空间索引效率分析模型技术在每一个商业应用中都会有一套特定的分析模型和评判标准,并且评估模式的指标和权重带有很大的主观性,需要引入科学方法来确定有效指标。探讨了针对PMR四叉树索引的空间索引效率分析的特殊案例,将最优化技术引入到空间索引效率分析中,使得空间索引的性能评价有了一定的理论依据。更多还原

【Abstract】 The efficiency analysis model technology of spatial index holds an especial analysis model and judgement standard in business,in addition,these indexes of evaluation mode are severe subjective,and these indexes must be confirmed by scientific method.The paper discusses an especial case of PMR quadtree index of spatial index efficiency analysis,because of optimization technology,the performance of spatial index holds academic foundation.更多还原
