ABSTRACT

It is widely accepted that natural gas is a clean energy source that can be used to meet energy demand for heating and industrial purposes among the fossil fuels and its usage remarkably increases in order to maintain a clean environment in many countries in the world. In this paper, factors affecting gas consumption were firstly identified and then GMDH-Type Neural Networks has been used for modeling and prediction of gas consumption using input-output data set. To validate the proposed model, a case study was carried out based on the data consisted of 84 sets for 7 years obtained from regional gas distribution company of Rasht city. For modeling, the experimental data were divided into train and test sections (70% for training and 30% for testing). The predicted values were compared with those of experimental values . The GMDH-Type Neural Network model values showed a very good regression with the experimental results and the Coefficient of determination was obtained 0.8943.
