采用行政区划国家标准建立了两个行业的δ-覆盖,并基于信息维数的定义,定量验证了企业分形分布的猜想,并测定了两个行业的分数维数.在此基础上将分数维数与嵌套区域秩序方法相结合,提出一种新的分形分布拟合方法FDF.经实际检验,FDF相比传统的方法,在所需数据量小、稳定性强、适应重点区域等方面,具有显著的特点和优势.最后,将该方法应用到一个调度实例问题,不仅给出了跨企业调度的优化范围,而且证明本文方法可以广泛应用于各类依赖于空间分布的企业协同研究. Based on the national standard of administrative divisions, the δ-coverage of two industries was established and the conjecture of the fractal distribution of enterprises was quantitatively verified on the basis of the definition of information dimension, and the fractal dimension of two industries was determined. On this basis, the fractal dimension Number and nested region order method, a new fractal distribution fitting method FDF is proposed.Through the actual test, compared with the traditional method, FDF has the advantages of small amount of data required, strong stability and adaptability to key areas, Which has notable features and advantages.Finally, applying this method to a scheduling instance problem not only gives the optimization scope of cross-enterprise scheduling, but also proves that this method can be widely applied to all kinds of enterprise collaborative research that depends on spatial distribution.
