Comprehensive Benefit Evaluation of Rural Household Biogas Based on Fuzzy Comprehensive Evaluation Method
The comprehensive benefit evaluation is the key of reasonable development for the rural household biogas. The evaluation index was established according to the economic efficiency, energy efficiency, ecological benefit and social benefits and so on, which was used to resolve the problem that the effect factors of comprehensive benefit evaluation of rural household biogas are more and the quantitative evaluation can't completely be finished.
