摘要: 针对舰船概念设计阶段的总体方案评估论证问题,提出了一种基于相对熵排序的舰船方案评价方法.首先提出了可全面反映舰船综合能力的经简化后的舰船方案评价的指标体系,然后考虑群决策中的专家意见集成问题.采用基于粒子群优化群体判断矩阵的Hadamard凸组合来集结专家意见得出底层评价指标权重,再引入基于相对熵的多属性排序方法对各舰船总体方案进行综合评价.形成了可支持多专家群决策,能有效反映各方案本质差异的舰船方案评价模型.应用实例对比分析表明,该方法可为舰船研制方案总体评价提供一种可行、有效的新途径,并可直接用于舰船设计方案的权衡、优化工作等方面.

Abstract: Warship evaluation during the stage of preliminary design presents a complicated decisionmaking problem. A relative entropy method for overall evaluation was proposed, that could present the comprehensive ability of warship. Regarding the opinion integration problem in group decision, the Hadmmard bulge combination was used to concentrate experts’ opinions, and a decision making method with multiple attributes based on entropy theory was introduced for evaluating. So a new decisionmaking method based on entropy theory was formed which supports both group decision and alternatives assessment with large difference. The new method was proved to be practical and efficient by practice.

Key words: warship overall, target system, group decision, relative entropy
