Application of Shannon Entropy in the evaluation of seven indicators from the gas station urban regions 1 and 7 ahvaz metropolis

Today, with the increasing use of vehicles in cities, Increasing the fueling stations (Gaz stations)it gets more attention. Improper spatial distribution of these locations and low quality of service and also a small number of them in cities including problems that will bring the minds of many researchers to urban issues. Quantity (number and mode of distribution, etc.)and quality (safety and service) as station sites of the most important factors In attracting citizens to supply fuel their vehicles are considered and leading to earn more money for station owners and provide more convenient service to users. This study is based on practical purpose. The method used is descriptive-analytical. As well as the relevant documents and questionnaires and field resources have been used. Using the shannon entropy technique has been, seven indicators of the status of the gas station in regions 1 and 7 metropolitan ahwaz the evaluation and ranking. the results showed that the ranking position of the gas station of the seven indices studied based on the shannon entropy model,gas stations;respectively ranked first and seventh,with the degree of priority,are located.Fotouhi, 3shercati, sepidar ,ghaem ,pol-e-panjom ,2shercati ,5shercati, 23/0709-22/0755-20/134-15/3703- 12/5983- 11/4321- 11/1331.
