Abstract:

The facility distribution is a hot issue in the urban layout, in which the representative Weber facility location is widely applied. Weber facility location can collocate the facility the best position in a discrete space and may solve location problem of various facilities. From the point of view of geocomputation, it can be divided into free facility location issue and restrained facility location issue depending on whether the facility orientation scope is restricted, namely whether the space network architecture is considered. It can also be divided into spatial damping and spatial no damping depending on whether it will have mutual effects among spatial geographical entities because of the distance. Based on different classifications, the Multiple Centers-of-gravity model, the Benefit Maximizing model and the p-center model are selected as the examples and computational methods in this study. In view of Integration and Development, the visual development kit Delphi 7.0 is generated as the development platform using specialized GIS widget MapObjects based on the OCX technology and the analysis system of the facility location is established to realize the computation and geographic analysis function of each model. And taking the social enterprise development of Xinqiao county and Songjiang district of Shanghai as an example, utilizing this system, the location problem of facility corresponding to the social enterprises development is solved. The analysis and computation of various distributions of the commune hospitals, the senior-citizen universities and the police workstations fully manifest that the research conclusion can provide a quantitative policy-making basis for reasonable distribution of infrastructural construction.
