灰色层次分析法在舰船中水回用方案优选中的应用

Application of grey analytic hierarchy process in water reuse optimization of warship

[目的]为解决舰船中水回用方案优选过程中决策影响因素多,且因素无法完全被量化和排序的问题,有必要建立科学合理的方案优选评估模型。[方法]基于灰色层次分析法及德尔菲法构建舰船中水回用方案评价指标体系的层次化结构,采用白化权函数的灰色评估方法对各评估要素进行量化,开展不同方案的综合评估。[结果]分析及计算结果表明,采用灰色层次分析法得出的综合评估结果合理,层次总排序的一致性检验满足指标要求。[结论]灰色层次分析法可以在专家评判的基础上,综合采纳各方面的意见,降低评判的随意性和主观性,提高方案选取的科学性和合理性,适用于对舰船中水回用的多方案、多目标系统设计进行优选决策。

[Objectives]As many factors influence decision-making in the course of warship water reuse scheme optimization,and such factors cannot be fully quantified and sequenced,it is necessary to build a scientific and reasonable optimization evaluation model.[Methods]Based on the grey analytic hierarchy process(AHP)and Delphi method,an evaluation index system for warship water reuse schemes with a hierarchical structure is constructed for the first time.The grey evaluation method of whitening weight function is used to quantify the evaluation elements and carry out the comprehensive evaluation of different schemes.[Results]The calculation results show that the obtained comprehensive evaluation results are reasonable,and the consistency test of the total hierarchical ranking meets the index requirements.[Conclusions]Based on expert judgment,grey analytic hierarchy process can comprehensively adopt opinions from all aspects,reduce the arbitrariness and subjectivity of judgment,and improve the scientificity and rationality of scheme selection.It is suitable for optimal decision-making of multi-schemes and multi-objectives water reuse system design for warship.
