Abstract There are some models for allocating any resources to many demands. This is the problem of many business and government institutes (Lea and Simmons, 2000), specially in third world countries where there is large demand for Infrastructure development communication, drinking water, educational facilities, public distribution system, electricity, financial institutions, markets, medical facilities & public health, transport, veterinary services, recreation & tourism which is the major concern of developing nations. (Inter-graph, 2002). In this paper different spatial allocation models are explained. A district called Pevejen from Mashhad countryside (North East of Iran) has been chosen to use its data for running the models. The case study is to determine the best location for building two schools and the results are compared.
