Analytic hiearchy process and its application in economic evaluation of coalbed methane project

An index system of hierarchy is established based on the characteristic researching of economic evaluation in coalbed methane projects.Using the analytic hierarchy process, the judgement matrix between general objective and each hierarchy is determined and the corresponding weight on the ecnomic evaluation is calculated.The results show that the judgement matrix is consistency, and it would provide foundation for evaluation of coalbed methane project.
