Definition of the Logistics Park Hinterland Based on Weighted Voronoi Diagram

Abstract

Accurately defining the radiation scope of the logistics park is the basis of the rational planning of the logistics park as well as further improvement of the regional logistics efficiency, but currently there is still a lack of scientific and systematical theory focusing on the research of defining the radiation scope of the logistics park. Therefore the concept of ‘hinterland’ was introduced into the research of the radiation scope of the logistics park, and the concept of ‘logistics park hinterland’ was particularly proposed. Subsequently, based on the Voronoi diagram theory in computational geometry which reflects the advantage of the continuity of space division, and by introducing the ‘scale’ parameter in the breaking-point model into weighted Voronoi diagram, the model based on weighted Voronoi diagram to define the logistics park hinterland was built. Finally, this model was practically applied to the planning example of ‘Four logistics centers’ of Chengdu, and also by means of GIS software the respective hinterlands of ‘Four logistics centers’ of Chengdu were defined. It practically proves that this model overcomes the shortcomings existing in the conventional single space division theories and methods such as the breaking-point model and the ordinary Voronoi diagram theory, which makes the definition of the logistics park hinterland more reasonable and scientific.
