Abstract: The evaluation indexes of submarine acoustic countermeasure schemes include the success probability of submarine evasion,submarine electric energy value,evasive time and the launch store ratio of acoustic countermeasure.According to different targets of submarine warfare,we analyze the evaluation indexes about acoustic countermeasure,and present a new comprehensive evaluation method based on multi-index methods including dictionary order,analytic hierarchy process,weighted integral,technique for order preference by similarity to ideal solution(TOPSIS),elimination et choice translating reality-III(ELECTRE-III),preference ranking organisation method for enrichment evaluations (PROMETHEE) ,and so on,as well as concentrating order methods including average order,Borda founction,Dodgson founction, and so on.Simulation results show consistency with actual situation.
