| Abstract: | A modified genetic algorithm based on fuzzy system （FMGA） was established to determine the weights of decision indictors of optimum selection for wastewater treatment processes. The computer simulation results showed that FMGA not only could avoid premature convergence, but also could calculate the weights of decision indicator quickly and stably. Finally, FMGA was applied to determine the indicator weights of optimum decision for urban wastewater treatment processes in Three Gorge Reservoir Area. The results showed that economic indicator （0.2602） 〉 technical indicator （0. 2094） 〉 energy indicator （0. 1891 ） 〉 professional skills required （0. 1423 ） 〉 complexity of operation and management （0. 1112） 〉 land area required （0.0878）. |
