Modeling the Spatial Resource Allocation Based on Justice Principle
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.
