Novel combinatorial algorithm for the problems of fuzzy grey multi-attribute group decision making

To study the fuzzy and grey information in the problems of multi-attribute group decision making, the basic concepts of both fuzzy grey numbers and grey interval numbers are given firstly, then a new model of fuzzy grey multi-attribute group decision making based on the theories of fuzzy mathematics and grey system is presented. Furthermore, the grey interval relative degree and deviation degree is defined, and both the optimistic algorithm of the grey interval relational degree and the algorithm of deviation degree minimization for solving this new model are also given. Finally, a decision making example to demonstrate the feasibility and rationality of this new method is given, and the results by using these two algorithms are uniform.

Grey information coverage interaction relational decision making and its application

This study aims to reflect the information coverage grey number and the interaction between attributes in grey relational decision making. Therefore, a multi-attribute decision method based on the grey information coverage interaction relational degree(GIRD) is proposed. Firstly, this paper defines the information coverage grey number, and establishes the GIRD model by using the Choquet fuzzy integral and grey relational principle. It proves that the proposed model not only is the general and unified form of the point relational degree, interval relational degree, mixed relational degree and grey fuzzy integral relational degree, but also can effectively deal with the interaction between attributes. Further,a decision making example of evaluating the industrial operation quality for 14 cities in Hunan province of China is provided to highlight the implementation, availability, and feasibility of the proposed decision model.

基于模糊联系度的危化品公路运输安全风险评估

为了有效降低危化品公路运输事故风险,提高危化品运输安全管控能力,构建了含23个动、静态指标的危化品公路运输安全风险评估指标体系,采用组合权重对评估指标赋权;基于集对分析理论,对专家打分分值与组合权重深入分析,引入综合差异度系数的概念,确定模糊联系度,提出一种危化品公路运输安全风险评估方法;以西安某公司至上海的运输任务为例,进行实例应用。结果表明:除危化品因素外,其余一级指标均存在风险上升趋势,其中人员因素风险上升趋势尤其明显,危化品公路运输整体风险状态处于微反势9级,风险较大,与实际情况相符。所提方法可实现危化品公路运输动、静态风险评估,为危化品公路运输风险研究提供参考。
