Why are decisions in flood disaster management so poorly supported by information from flood models?

Flood simulation models can provide practitioners of Flood Disaster Management with sophisticated estimates of floods. Despite the advantages that flood simulation modeling may provide, experiences have proven that these models are of limited use. Until now, this problem has mainly been investigated by evaluations of which information is demanded by decision-makers versus what models can actually offer. However, the goal of this study is to investigate how model information is exchanged among participants in flood disaster organizations and how this exchange affects the use of modeling information. Our findings indicate that the extent to which a model is useful not only depends on the type and quality of its output, but also on how fast and flexible a model can be. In addition, methods of model use are required that support a fast exchange of model information between participants in the flood disaster organization.     

Linguistic group decision making with induced aggregation operators and probabilistic information

A new approach for linguistic group decision making by using probabilistic information and induced aggregation operators is presented. It is based on the induced linguistic probabilistic ordered weighted average (ILPOWA). It is an aggregation operator that uses probabilities and OWA operators in the same formulation considering the degree of importance that each concept has in the formulation. It uses complex attitudinal characters that can be assessed by using order inducing variables. Furthermore, it deals with an uncertain environment where the information cannot be studied in a numerical scale but it is possible to use linguistic variables. Several extensions to this approach are presented by using moving averages and Bonferroni means. The applicability of this approach is also studied with a focus on multi-criteria group decision making by using multi-person aggregation operators in order to deal with the opinion of several experts in the analysis. An illustrative example regarding importation strategies in the administration of a country is developed.     

面向工业物联网环境下后门隐私泄露感知方法

伴随工业物联网相关技术的高速发展,后门隐私信息的泄露正成为一个重大的挑战,严重威胁工业控制系统及物联网环境的安全性及稳定性.本文基于工业物联网环境下后门隐私的数据特征定义若干基本属性,根据静态及动态数据流安全威胁抽取上层语义,并基于多属性决策方法聚合生成静态与动态泄露度,最终结合灰色关联分析计算安全级与安全阈值,以此实现后门隐私信息在静态二进制结构及动态数据流向中的泄露场景感知.实验选择目标环境中27种后门隐私信息进行测试,依次计算并分析基本定义、上层语义及判决语义,通过安全级与安全阈值的比较成功感知多种后门泄露场景.实验还将本文工作与其他相关模型或系统进行对比,验证了所提方法的有效性.
