System resilience denotes the capacity to uphold desired system performance in the face of disruptions. Evaluating the resilience of a process system necessitates a thorough consideration of the intricate interplay between its components and the pivotal role of process parameters in reflecting the repercussions of disruptions on the system. This paper introduces an integrated methodology that takes into account component interactions and leverages process data for the resilience assessment of a process system. The proposed methodology comprises four key components: system structure analysis, disruption impacts analysis, process simulation, and resilience assessment. Firstly, the system structure is meticulously scrutinized using a P-graph model. This analysis encompasses the assessment of the significance and interplay of components, as well as the evaluation of how component failures affect the system's overall processes. Secondly, a Markov model is devised to examine the state transition process of components and quantifies the maintenance time needed for failed components. Subsequently, a simulation model is formulated to acquire real-time process parameters in the presence of disruptive events. Finally, the system's performance response function (PRF) is derived from the normalization of these process parameters. Building upon this foundation, a resilience assessment is conducted with a focus on the PRF. To illustrate the effectiveness of this methodology, an LNG terminal system is employed as an exemplar.

Metro stations are mostly located below ground, connected to the outside would through limited channels; the environment is relatively closed. In the event of fire and other emergencies, the evacuation of people from the station is relatively difficult, and evacuation safety judgment and evacuation method still need further research. In order to study the influencing factors of passenger evacuation in the event of an emergency at a subway station and improve evacuation efficiency, a subway passenger fire evacuation model was constructed and simulated according to the variable relationship and response model of subway passenger fire stress response. Based on the system dynamics method, the subway passenger fire stress response model was constructed to simulate the stress response process. This study shows that after 2 min, with the increase of the proportion of passengers responding to problems, the level of passengers' stress response gradually increased. Evacuation efficiency directly affects evacuation time, and the ability to deal with the problem also directly affects the level of stress response, thereby affecting evacuation efficiency. The research results provide a scientific basis for optimizing emergency evacuation plans and strategies, enhancing passenger safety awareness and emergency capabilities, and ensuring the safe operation of the subway.

In order to effectively reduce the psychological anxiety of subway passengers in the fire state and improve the effect of fire emergency management, the fire anxiety status of passengers of different genders was counted, based on the fire state-trait anxiety questionnaire. The questionnaire and mathematical statistics were used to discuss the influence of different time periods after the intervention of on-site drills on the psychological anxiety level of passengers. Results: Before the field exercise, the overall fire anxiety level of the sample was in the normal range ; After on-site exercise, female fire anxiety level decreased, but still did not eliminate anxiety, and the effect of male education is not obvious ; After one hour of on-site training, the overall scores of fire anxiety of the samples were reduced; One day after the on-site exercise, women’s psychological anxiety scores began to improve, and men’s psychological anxiety continued to improve. Conclusion: On the whole, on-site drills are effective. After one day of on-site drills, the intervention effect basically disappears. However, on-site drills have a significant effect on eliminating the tension in the face of subway fires, and there are significant differences in these aspects of characteristics between people of different genders in the face of subway fires.

为降低高断面客流峰值和大客流车站客流密度,减轻轨道交通运输压力,以轨道交通昌平线为例,首先采用回归分析法对轨道交通昌平线进行客流相关性分析,并通过移动平均法和加权移动平均法对未来客流量进行预测;然后分别计算方向不均衡系数、断面不均衡系数以及断面满载率,从而进行线路客流量均衡性评价;最后对未来运行图的调整提出合理建议.分析结果表明:轨道交通昌平线运行图自2020年9月使用以来,预测客流量较历史同期数据上升约8.4％,可以考虑对运行图进行部分调整,且昌平线早晚高峰时客流更加集中,可以作为运行图优先调整的对象;早晚高峰区间车辆满载率除1项在规定值之内,其他均超过规定值,且早高峰满载率存在过百的情况,对新冠肺炎疫情防控工作造成隐患.

In recent years, green product issues have received increasing attention. Both government regulations and consumer behaviors have a strong influence on the product green degree decisions of manufacturers’ products. In order to find how government regulations and individual’s green product purchase behavior affect manufacturers’ green degree decisions and the market evolution characteristics, this paper proposes a multiagent model that considers the interaction among government, consumers, and manufacturers. The simulation results show that, firstly, the product green degree decision-making of manufacturers needs the guidance and regulation of the government. Secondly, product price subsidies are the most effective way to affect the manufacturers’ product green degree decisions. In contrast to giving green cost subsidies to manufacturers, the government employs various publicity means to improve the environmental awareness of consumers is also an effective way to enhance the green degree of manufacturers’ products. Thirdly, there is a “Crowding Out Effect” on the other qualities of manufacturers’ products when manufacturers focus on the green degree of their products.

Catastrophe theory can describe a continuous process that is undergoing abrupt changes. A dynamic process can be considered to be a swallowtail catastrophe if it has the following six qualities: bimodality, divergence, sudden transitions, hysteresis, inaccessibility and irreversibility. In this paper, the swallowtail catastrophe model is applied to describe the changing dynamic process of subway fire accidents. This dynamic process is also proved to have the six qualities of a swallowtail catastrophe. By using the swallowtail catastrophe model, we construct a model for the subway fire accidents, and we present analyses of subway fire accidents. On the basis of the model and analyses, the dynamic changes in the subway fire accident evolution process can be described with a novel approach. The causes of fire accidents in subways are also discussed, from the perspective of the fire triangle and four elements of an accident. We hope that this study's theoretical descriptions and discussion of subway fire accidents will facilitate a profound analysis of subway safety.

In this study, we set up a virtual subway car and analyzed the stress response of young passengers in different compartments. A total of 10 volunteers participated in the experimental study. We measured their diastolic blood pressures, systolic blood pressures, and heart rates, from a car density of one person per square meter to a density of 10 persons per square meter, using 37° sport wristbands. The results show that the participants’ mean, minimum, and maximum heart rates were within the normal range, but the ratio of their mean to their maximum heart rate was 73.69%, a level that would have an impact on human health. Their mean, minimum, and maximum diastolic blood pressures and systolic blood pressures were within the normal range. Passenger density had no significant effect on diastolic blood pressure, systolic blood pressure, or heart rate (p < 0.05). Diastolic and systolic blood pressures were significantly positively correlated, whereas diastolic blood pressure and heart rate, and systolic blood pressure and heart rate, were negatively correlated, although not significantly. For the sake of comfort, we recommend five persons per square meter as the critical value of congestion.
