Based on effectiveness analysis, a novel method is presented for combat aircraft top-hierarchy concept evaluation and decision-making. Applying multi-criterion decision-making (MCDM) and analytic hierarchy process, the new method can help to overcome the limitations of existing evaluation systems and decision-make methods. The proposed method includes the following process~ (1) Establish a multi-criterion and multi-hierarchy evaluation attribute system by introducing combat effectiveness~ (2) Assign weight to the attributes and normalize them; (3) Evaluate and decision-make top-hierarchy aircraft concept based on effectiveness to reach a satisfactory design by comprehensively applying four multi-criterion decision-making methodologies, i.e. grey correlation pro- jection method, weighted summation method, weighted quadrature method and ideal solution decision-making method, while considering the attribute hierarchy system and the logical relations among the attributes. Finally, an example is given to indicate the validity and feasibility of the proposed method. 相似文献

提出了综合应用灰色关联投影法、加权求和法、加权求积法和基于理想点决策法来实现对无人作战飞机顶层方案的优选,并着重介绍了多准则决策方法及实施过程。该方法采用不同的公度化方法处理相应的评价指标,对多目标、多层次指标体系进行赋权,利用权重将评价指标联系在一起,并将四种准则决策法进行综合,依据决策者的偏好,最终实现顶层方案的优选。最后,通过制空无人作战飞机顶层方案优选的例子,证实了所提方法是可行且有效的。 相似文献
