基于改进ELECTRE法的舰船气流场方案评估方法

从气流场对舰载机作业的影响出发，构建了气流场评估指标体系。针对层次分析法一致性检验的缺陷，结合群决策特征根法（GEM）和决策熵理论，提出了结果可靠性可量化的气流场评估的赋权方法。结合模糊集理论知识，将经典ELECTRE法拓展到模糊环境下；排序计算中涉及到的指标评价值以三角模糊数的形式给出；使用改进ELECTRE法进行气流场方案的排序，模糊数计算保证了对大量模糊数据的完整处理。通过对3种不同气流场方案进行评估应用实例结果表明，所提出的舰船总体方案群决策方法具有较好的可行性，为舰船气流场方案评价提供了一种新的方法。

Evaluation method of airflow field plan in warship based on improved ELECTRE method

Based on the influence of airflow field on deck-landing aeroplane operations, an evaluation index system for airflow field of warship is constructed. In view of the defect of consistency check by analytic hierarchy process (AHP), a weighting method which is combined with group eigenvalue method (GEM) and the theory of decision entropy is formed; the method can obtain outcomes, whose reliability is quantifiable. Combining the concepts of fuzzy theory, the classical elimination et choice translating reality (ELECTRE) method is extended for fuzzy multiattribute group decision making; all attribute values in sorting are expressed in triangular fuzzy numbers; when airflow field plans of warship are sorted with improved fuzzy ELECTRE, the use of fuzzy number ensures the complete processing of fuzzy data which is from the experts. Evaluation-computing is run for three airflow field plans, which verifies the feasibility of this improved evaluation method that can be a new method for general airflow field plan evaluation.
