突发事件下三级供应链联合契约协调

突发事件会对基于随机需求的市场产生巨大的波动，造成供应链系统的不稳定，打破原有的协调。为此，构建了突发事件下供应链协调的应对策略，建立了收益共享-两部收费（RS-TT）联合契约。研究表明：突发事件前，联合契约可以实现供应链的协调；突发事件后，原契约不会起协调作用。因此，对原契约及契约参数进行改进，并通过算例分析验证了改进后的契约可以使供应链达到全局最优的状态且具有抗突发事件性。

水利工程高危作业突发事件演化机理尖点突变模型研究

为减少水利工程高危作业突发事件形成,控制事件影响,在分析高危作业施工安全风险影响因素的基础上,得出突发事件演化机理图;结合突变理论,将内在动因和外在诱因作为控制变量、施工安全动态作为状态变量,构建水利工程高危作业突发事件尖点突变模型。通过模型进一步分析事件形成过程,阐述分裂因子和正则因子在突发事件前、后的作用及事件演化轨迹,同时总结出安全作业(2种)、外因隐患作业、内因隐患作业、危险作业(2种)共6种施工安全状态,进而提出突发事件的预防措施、控制措施、应急措施。研究表明:作业人员素质的提升是避免突发事件形成的关键因素,管理人员的行为在事件发生前后极具影响力。该模型研究对水利工程领域中的高危作业安全保障作出了进一步的理论探索。     

The responsive bystander in emergencies: Some preliminary data.

The bystander-intervention literature has seemingly neglected the responsive bystander in emphasizing the absence of helping behavior. In reversing this trend, some characteristics of two groups of responsive bystanders were examined. The sample included 101 Carnegie Hero Medal recipients and 147 Toronto Metropolitan Police Civilian Citation recipients. The data indicated that males directly intervened in emergencies more often than females and that the responsive bystander tended to act alone. The Carnegie analysis suggested that rural people were more heroic than urban people, although possible confounding factors were considered. Some future research suggestions were offered.

突发事件下的医院应急资源动态分配模型研究

针对突发事件下医院里应急资源供需不平衡的问题，进行了医院应急资源动态分配模型研究。考虑到病人数量增多以及病人伤情演变导致医院应急资源供应相对紧缺的现象，基于序贯决策理论，将病人需求的变化设计成一个马尔可夫决策过程，建立了医院应急资源动态分配模型。使用基本粒子群算法求解，通过某次地震发生后医院的救援实例进行分析。案例分析表明，马尔可夫决策过程可以动态地满足伤情演变下不同状态病人的需求，使得应急救援中整体的资源利用达到最优。     

Coordination-behavior patterns of control crews in digital nuclear power plants during emergencies from a network perspective: An exploratory study

This study aims to investigate the coordination-behavior patterns of control crews in digital nuclear power plants (NPPs) during emergencies from a network perspective. We observed and coded 12 coordination processes (each from one crew) of handling simulated emergencies on a full-scope dynamic simulator in Tianwan NPP of China. By calculating the proportion of coordination breakdowns and referring to the subjective evaluation of instructors, these control crews (all male) were classified into two performance levels (high and low). To compare the coordination-behavior patterns between high- and low-performing crews, we conducted social network analysis based on the number and direction of coordination behaviors. By examining intracrew relations in team coordination, this study indicated that high-performing crews exhibited higher cohesion and more balanced behavioral patterns in team coordination than low-performing ones. By investigating coordination-behavior patterns from the hierarchical structure of relations in the team, this study revealed that high-performing crews exhibited higher degree of team autonomy and self-management among junior operators, as well as reactor operator (RO)-centered pattern, whereas the low-performing crews exhibited senior reactor operator-centered pattern. For researchers, the results advance the understanding of the team coordination mechanism in NPP control rooms during emergencies and enrich team coordination theory in process control industries from the network perspective. In practice, this study suggested that the team coordination training of NPP control crews might be centered around junior operators (especially RO), with focuses on facilitating information sharing and mutual assistance between junior operators and enhancing the awareness of active cooperation of crew members. The results of the study provide nuclear instructors with practical reference to team coordination training and processes optimization.     

突发事件Web新闻中时间信息分析及抽取

为了更深入地挖掘突发事件Web新闻并应用于应急管理，提出了突发事件Web新闻时间抽取方法。首先引入中文的时间关系理论；然后从突发事件Web新闻的时间构成、时间位置特征以及时间常用词三个方面分析了突发事件Web新闻的表达特征；基于此，提出突发事件Web新闻的时间抽取方法，通过统计学习，正确率较理想；最后，基于已抽取到的事件发生时间信息，程序实现了突发事件Web新闻排序。
