Abstract:
For lo ng2dist ance w ate r tr ansfer pr oject s, w e pro po sed six indexes w hich affect t he effects o f g ate contr ol in emer2 g ency reg ulation. T he six index es include contr ol tim e, spher e of po llutio n after co ntro l, pea k co ncentration o f po llutants af2 ter contr o l, co st of co nt ro l, diff iculty lev el o f contr o l, and im pact o f co ntr ol o n the pr oject. T hen w e used the analyt ic hierar2 chy pro cess t o establish and quantify these index es, and adopted the g r ay fixed w eig ht clustering metho d t o conduct g r ay classificat ion o f the g ate contr ol mo des. We esta blished the tr iang ular w hitening w eig ht function so as to det erm ine the gate co ntr ol mo de m or e accurately.
