Abstract:The main evaluation methods of ship anti-missle operational effectiveness include system effectiveness analysis,availability dependability,combat simulation and analysis hierarchy process, etc. In these methods, there are such prob.lems as the difficulty of evaluating multi-system,no considering inter-system interaction and in-system interaction, etc.These problems lead to the deviation of evaluation results. For this reason, in this paper, ANP method based on the im.provement of analysis hierarchy process method is proposed to solve such problems as inter-system, in-system interaction,and the difficulty of evaluating multi-system. Analysis results showed that this method was simple and practical, and iseasy to be widely accepted.
