摘　　要：针对核与辐射环境应急监测中新型智能化仪器研制需求,本文将模糊层次分析法、熵值法和改进的灰色综合关联分析法三者结合,提出了一种组合赋权和改进的灰色关联分析综合评价方法,对多个辐射探测器的抛投装置最优设计进行了模糊多目标决策。通过对抛投装置建立多层次评价模型,采用层次分析法确定主观权重、熵值法确定客观权重,将两者组合赋权得到各层以及相关指标的组合权重,运用具有区间模糊数的灰色关联法确定关联度系数,最终计算出各方案的灰色综合关联度评价值,以此评价得出最优抛投方案。利用此方法,定量的反映出各层因素间的相互关系,解决了辐射抛投装置多个指标方案优选中的相互影响性问题,实现了对抛投装置的综合评价,并验证了该模型在最优抛投装置选择中的可行性。Addressing the development requirements of novel intelligent instruments for nuclear and radiation emergency monitoring,this paper integrates the fuzzy analytic hierarchy process,the entropy method,and the improved grey relational analysis to propose a combined weighting and enhanced grey relational analysis comprehensive evaluation method.It conducts fuzzy multi-objective decision-making for the optimal design of throwing devices for multiple radiation detectors.By establishing a multi-layer evaluation model for the throwing device,subjective weights are determined using the analytic hierarchy process,and objective weights are determined using the entropy method.The combination of the two yields composite weights for each layer and relevant indicators.The grey relational analysis method with interval fuzzy numbers is employed to determine correlation coefficients.Ultimately,it calculates the grey comprehensive correlation degree evaluation values for each scheme,thus evaluating and determining the optimal throwing solution.This method effectively quantifies the relation between various factors,addresses the mutual influence issue in the optimal selection of radiation throwing devices,achieves comprehensive evaluation of the throwing device,and validates the feasibility of the model in selecting the optimal throwing device.
