Abstract :
Based on analyzing the factors affecting the longitudinal motion performance of SWATH, this paper establishes the layered evaluating index system of the longitudinal motion performance of SWATH. The analytic hierarchy process is used to determine the weight coefficients of the evaluating index. Then this paper evaluates the longitudinal motion performance of SWATH using the fuzzy comprehensive evaluation method and the steps of evaluation are also provided. The actual example shows that the evaluation method is reasonable and effective. Further more, this method can provide the theoretic support for the determination of the project of the stabilizer fins and the overall design of SWATH.
