Abstract

The virus 2019-nCoV rapidly crossed the globe in the first quarter of 2020, and the global civil aviation industry contributed to the spread of the virus. The aircraft deplaning process is one of the critical stages of the spread of infectious diseases and merits careful research accordingly. However, little effort has been made to tailor the civil aircraft deplaning process to the existence of patients with severe acute airborne disease. In this study, we explore a mixed patient-health pedestrian deplaning flow from a Boeing 737-300’s with a full economy-class layout as per the virus spread dynamics during the process. We develop feasible deplaning management strategies that can reduce the inflection risk to the healthy passengers during the deplaning process. We then quantitatively compare the deplaning process before and after adopting the proposed strategies. The numerical results show that the proposed strategies effectively reduce the risk of infection during the deplaning process but sacrifice deplaning efficiency. We assert that health outweighs efficiency, and find that the proposed strategy may thus have practical value and potentially be of use to administrators.

摘要

2019-nCoV病毒在2020年第一季度迅速席卷全球，全球民航业助长了病毒的传播。飞机下机过程是传染病传播的关键阶段之一，值得认真研究。然而，几乎没有做出任何努力来调整民用飞机下飞机过程以适应患有严重急性空气传播疾病的患者的存在。在这项研究中，我们根据病毒在此过程中的传播动态，探索了一架波音 737-300 的混合患者健康行人下飞机流，该飞机具有完整的经济舱布局。我们制定可行的下机管理策略，以减少下机过程中对健康乘客的影响风险。然后，我们定量比较采用建议策略之前和之后的下飞机过程。数值结果表明，所提出的策略有效地降低了下飞机过程中的感染风险，但牺牲了下飞机效率。我们断言健康重于效率，并发现所提出的策略可能因此具有实用价值并可能对管理员有用。
