in this paper, an adaptive-network-based fuzzy inference system (anfis) is used for forecasting of natural gas consumption. it is clear that natural gas consumption prediction for future, surly can help statesmen to decide more certain. there are many variables which effect on gas consumption but two variables that named gross domestic product (gdp) and population, are selected as two input var...

the natural gas consumption in iran has been continuously increasing due to several reasons including low prices of natural gas, development of gas supply networks, people’s salary increase, incorrect consumption culture and the increase of national economy growth.  although, the global natural gas consumption has increased by 38% since 2001, the national consumption in iran has increased by 11...

the request for natural gas attention to its adaption with environment and less pollution than the other fossil fuels has the highest growth in last decades. in result this energy has high geopolitical importance. iran with has about 2.18 percent of total world reserves, the largest in the world. but couldn't played important role in the natural gas geopolitics and even it hasn't in b...

the purpose of this research is to found the impact of built area and occupant number on winter gas consumption in the residential building sector of iran, shiraz.sothe annually and monthly gas consumption data through 19 houses were analyzed to achieve the heating energy consumption and operation month.the average operation months of gas heating consumption were from first of november up to en...

a laboratory stirred tank bioreactor with six single and dual-impeller configurations was tested to obtain the optimum operating conditions for future biological processes. six impeller combinations consisting of three basic impeller types, namely rushton turbine (rt), pitched 4blade (p4b) and pitched 2blade (p2b) downward flow were investigated in 1.77 l bioreactor working volume. power consum...

In this paper, an Adaptive-Network-based Fuzzy Inference System (ANFIS) is used for forecasting of natural gas consumption. It is clear that natural gas consumption prediction for future, surly can help Statesmen to decide more certain. There are many variables which effect on gas consumption but two variables that named Gross Domestic Product (GDP) and population, are selected as two input var...
