Abstract :
大规模灾害救援初期,应急物资供应不及时和分配不均的状况会使灾民产生一定的负面心理情绪,影响灾后救援效率。针对该问题,本文构造绝对剥夺成本函数和相对剥夺成本函数衡量灾民的负面心理情绪,并利用总剥夺成本表征应急物资调配的公平性,以救援总成本最小为决策目标,构建兼顾效率和公平的灾民应急疏散、临时避难所选址和应急物资调配的集成优化模型,并设计一种分阶段解码的遗传算法进行求解。最后,以易受台风侵袭的广东省东莞市与汕尾市的19个城镇作为受灾点进行算例分析,验证了模型与算法的有效性和可行性,以期为灾后应急救援提供有益参考。

Abstract :
环境规制对绿色生产具有重要的积极意义,区域环境规制水平与碳交易价格波动之间存在密不可分的关系.以国内4个碳交易试点为研究对象,选取了 2013-2020年不同区域环境规制的相关指标和碳交易价格数据进行实证分析,深入探讨环境规制对碳交易价格波动的作用机制.同时采用滞后一期的方法解决内生性问题可能会对分析结果带来的影响.研究发现:环境规制水平对碳交易价格具有抑制作用,地理距离的变化会改善环境规制水平对碳交易价格的抑制效应.

Abstract :
灾后应急物资的分配与调度是救援工作开展的关键任务.为保障灾后物资配送活动的顺利进行,对应急配送中心的选址-路径问题展开研究,构建一个物资储备库-应急配送中心-需求点的多级配送网络.在考虑灾区道路可靠性状况的条件下,综合考虑供给物资有限、物资分配的公平性、需求的不确定性等因素,以应急物资总配送时间最小化、系统总成本最小化以及车辆行驶路线的总连通可靠性最大化三者为目标函数,采用随机机会约束规划方法,建立了一个震后应急物资配送的多目标选址-路径问题优化模型.考虑到问题的复杂性,文章利用基于蒙特卡洛仿真模拟的非支配排序遗传算法对所提出的问题进行求解.通过测试算例,证实了文章所提出的模型和算法能有效求解灾后应急配送中心多目标选址-路径优化问题,为决策者选择适合的方案提供一定参考.

Abstract :
The transportation mode of the railway cold chain has an essential impact on operational efficiency and cost. Under the uncertainty of demand and limited transportation capacity, an evolutionary game model of railway cold chain logistics is constructed to explain and analyze the dynamic decision-making processes and mechanisms between cargo owners and railway transport enterprises. The results show that the evolutionary path and convergence speed of the model are influenced by the initial value and its allocation coefficient, cargo volume, additional benefit, and default cost. By using Matlab, numerical simulation is conducted to verify the theoretical assumptions and results. The conclusion provides a basis for studying and managing railway cold chain logistics. © 2023 Ling Zhang et al.

Abstract :
This study presents a novel approach to analysing environmental governance by Chinese governments through the lens of a tripartite evolutionary game model. The key novelty of our research lies in the explicit incorporation of a reputation mechanism into the evolutionary game analysis, which significantly influences government decision-making, environmental governance strategies, and the dynamics of the relationship between government and polluting enterprises. By assessing the marginal effects of conventional governance and mobilization-based governance on the environmental mechanism, as well as the collusion behaviours between government and polluting enterprises, our study sheds light on previously unexplored aspects of environmental governance. Our findings indicate that the reputation mechanism plays a crucial role within the evolutionary game system of environmental governance, exerting a substantial impact on government decision-making. Furthermore, we demonstrate that policy interventions, such as increasing the cost of penalties under regulatory policies, can encourage compliance strategies among enterprises. Additionally, our research highlights the high sensitivity of reputation signals towards local government's environmental governance strategies, directly impacting their credibility and influencing the adoption of proactive environmental governance strategies. Moreover, we emphasize the role of the central environmental inspection system as a means to facilitate the transmission of environmental governance pressures between central and local governments, ultimately fostering a green development concept and promoting coordinated development between the economy and ecological civilization. Overall, this study provides valuable insights into the intricacies of environmental governance in China and underscores the importance of reputation mechanisms and policy interventions in promoting sustainable development.

Abstract :
地震等突发事件发生后需要血液等挽救生命的重要应急医疗资源对伤员进行救治,然而灾后对于血液的需求通常是不确定的,考虑到无法提前获取不确定性信息完整分布情况,因此在设计应急血液网络时应使其具有鲁棒性。为了保障灾后安全救援能够顺利进行,提出一种分布式鲁棒优化框架,结合使用均值-CVaR方法来有效地度量决策者的风险规避特征,建立临时献血点选址分布式鲁棒优化模型,目的是解决血液供应不足时候选地的选址问题。通过寻找过去灾害发生时需求的历史数据,将突发事件中的血液需求表示成模糊集形式,并利用python中的Rsome鲁棒优化第三方库求解模型。通过实际案例分析,验证了该决策模式的适用性,表明所建立的模型能够为...

Abstract :
Although the ability to manage public health emergencies in China has improved signicantly, there are still many challenges to the existing information transmission mechanism in pandemic early warning systems. In this context, a tripartite evolutionary game model composed of the local government, the whistleblower, and the public is formulated. By using Matlab, the dynamic evolution path of the game model is stimulated under different conditions. Stable strategies for an early warning system for public health emergencies are also explored. e results indicate that the cost of whistleblowing, the cost of response, and the benet of attention signicantly influence strategic decisions among three parties. is study highlights the importance of whistleblowing in managing public health emergencies. Yet, our ndings provide theoretical support for policy recommendations for promoting public health emergency preparedness.

Abstract :
近年来,我国遭受各种重大突发灾害,给人民的健康以及经济社会发展造成了巨大危害。在突发事件中,缺乏有效的供应商管理,会使得应急物资管理效率低下,而实施供应商管理能够有效提升应急物资的供应能力。基于此,在有关供应商评价以及应急物资供应商选择的文献研究基础上,从时间、应急物资质量、应急物资价格、应急能力以及经营环境五个维度,构建了应急物资供应商评价的16个指标。以某省的18家应急物资供应商作为研究对象,利用BP神经网络对这些应急物资供应商进行评价。结果表明,此模型避免了主观影响与不确定性,可以有效地应用到应急物资产品供应商评价中。
