Abstract: Considering the characteristics of submarine concept design, a new evaluation model and measure was put forward to assess the overall performance of submarine. By using a three level dominance scale method, the compa rison matrix was created indirectly, which reduced the influence of decision maker s subjective experience to a certain extent. The statistical method, which takes the critical value of consistency index (C.I.) of th he comparison matrix as the test criterion, was used to test the consistency of the pair-wise judgments. This method is simple, practical, and theoretically feasible.
