基于信息集成算子的舰船舱室设计方案评估

Evaluation of warship cabin design scheme based on information aggregation operator

针对舰船舱室设计的复杂性和多样性,提出了一种基于信息集成算子的多属性决策评估方法,以提高舰船舱室设计决策的科学性和实用性.首先建立反映舰船总体设计要求,同时兼顾舰员实际需求的评估指标体系和多属性决策矩阵;其次基于模糊数直觉模糊数的求解运算方法,对设计方案的单个属性和属性集进行模糊测度,采用Choquet积分对专家意见和评价属性进行综合集成,获得反映多属性群决策本质的信息集成算子;最后应用评价函数法构建舰船舱室设计方案的综合评估模型.通过实例分析和算法对比得出,基于信息集成算子的舰船舱室设计方案评估方法准确、可靠,能够更为有效地判断多个设计方案的优劣,为烦琐的舰船舱室设计方案决策提供一种新的有益参考.

In order to solve the complexity and diversity of warship cabin design and make decisionmaking more scientific and practical,an evaluation method of multiple attribute decision-making based on information aggregation operator is proposed.First,the evaluation index system and multiple attribute decision-making matrix are established,which reflect the requirements of designers and crews.Second,based on the operational method of fuzzy number intuitionistic fuzzy numbers,the fuzzy measure of attributes and attribute sets of different design schemes is calculated and then expert advices and evaluation attributes are integrated by Choquet integral,and the information aggregation operator which can reflect the nature of the multiple attribute group decision-making is obtained.Finally,the comprehensive evaluation model of warship cabin design scheme can be founded by score function.By means of case analysis and algorithm comparison,the evaluation method of warship cabin design scheme based on information aggregation operator is proved to be accurate and reliable.This method can more effectively judge the pros and cons of multiple design schemes,and provide a new and useful reference for the tedious decision-making of warship cabin design scheme.
