Modeling the spatial resource allocation based on justice principle

Abstract(summary):

The spatial distribution of resources and services needs to be planned and allocated thoroughly in order to satisfy the demands of social justice. The spatial accessibility indices are well-known for their significant roles in the fields of planning and allocation for resources. In this paper； we present a Spatial Resource Allocation Model based on Justice Principle. In the model； a group of linear equations of the supplies' resources are deduced according to the gravity-based accessibility index. The model consists of two submodels: one is for supply； and another is for demand. The submodel for supply ensures that every supply has the same gravity-based accessibility index； which is equal to the total demands-total supplies ratio in the value of 1. At the same time； the just allocation submodel for demand ensures that every demand has the same gravity-based accessibility index； which is equal to the total supplies- total demands ratio in the value of 1. The Matlab-based commands are utilized to implement the model and an application example is given to demonstrate the utility and effectiveness of it.
