The COVID-19 pandemic has disrupted the normal operations of countries around the world, which applied different containment and mitigation policies, such as mask-wearing, social distancing, quarantine, and lockdowns, to limit the spread of the virus. More recent mitigation efforts include vaccination strategies, since various vaccines have been authorized for emergency use for the prevention of COVID-19. In fact, vaccination is one of the best proactive mitigation strategies against the virus spread. Mass vaccination strategies have been undertaken by multiple research and development teams in the past when the public needed to be vaccinated on a large scale due to a pandemic, such as the seasonal flu or H1N1. Drive through vaccination, in particular, is more convenient and safer than walk-in vaccinations in clinics due the nature of the contagious virus. In this paper, we present the implementation of a discrete event simulation model of a drive through clinic for mass vaccinations of patients, while prioritizing the senior population. The simulation output is examined in terms of average waiting time in the queue to get vaccinated, number of patients getting vaccinated per week, and utilization of the medical resources. The results are expected to provide insights into the allocation of medical resources across lanes and prioritization strategies for the senior population to achieve higher vaccination rates, while reducing the waiting time in queue. © 2021 The Authors.
新冠肺炎大流行扰乱了世界各国的正常运作,各国采取了不同的防控政策,如戴口罩、保持社交距离、隔离、封锁等,以限制病毒的传播。最近的缓解努力包括疫苗接种战略,因为已授权紧急使用各种疫苗来预防COVID-19。事实上,疫苗接种是预防病毒传播的最佳主动缓解策略之一。过去,当季节性流感或H1N1等大流行导致公众需要大规模接种疫苗时,多个研究和开发团队采取了大规模疫苗接种战略。由于这种传染性病毒的性质,开车接种疫苗比在诊所接种疫苗更方便、更安全。在本文中,我们提出了一个离散事件模拟模型的实现,该模型通过诊所为患者大规模接种疫苗,同时优先考虑老年人。根据排队接种疫苗的平均等待时间、每周接种疫苗的患者数量和医疗资源的利用率来检查模拟输出。该结果有望为老年人提供跨车道医疗资源分配和优先级策略的见解,以实现更高的疫苗接种率,同时减少排队等待时间。©2021作者。

The Impact of the Constraints of Class Scheduling on Campus Dining: A Simulation-based Case Study 课程安排约束对校园餐饮的影响:基于模拟的案例研究

Waiting in queues in service systems is an inevitable part of the customer's everyday routine. Waiting time is an important indicator of a service system's performance. This paper studies the efficiency of service operations in a college campus dining setting. The authors implemented a discrete event simulation (DES) model in Simio to study how class scheduling may affect the overall customer waiting time and satisfaction at the college campus dining location. The results provide recommendations on how classes could be scheduled to optimize students' satisfaction with their lunchtimes and the quality of service. The results also provide valuable insights for operating during the COVID-19 pandemic, as campus dining locations have a decreased maximum capacity, which may lead to more bottlenecks than usual and increase waiting times. © 2021 The Authors.
在服务系统中排队等候是客户日常生活中不可避免的一部分。等待时间是衡量服务系统性能的重要指标。本文以某高校校园餐饮服务运作效率为研究对象。作者在Simio中实现了一个离散事件模拟(DES)模型来研究课程安排如何影响大学校园用餐地点的整体顾客等待时间和满意度。研究结果为如何安排课程提供了建议,以优化学生对午餐时间的满意度和服务质量。研究结果还为2019冠状病毒病大流行期间的运营提供了有价值的见解,因为校园餐饮场所的最大容量下降,这可能导致比平时更多的瓶颈,并增加等待时间。©2021作者。

By testing various physics levels for training autonomous-vehicle navigation using a deep deterministic policy gradient algorithm, the present study fills a lack of research on the impact of physics levels for vehicle behaviour, specifically for reinforcement-learning algorithms. Measures from a PointGoal Navigation task were investigated: simulator run-time, training steps, and agent effectiveness through the Success weighted by (normalised inverse) Path Length (SPL) measure. Training and testing occurred in the novel simulator ARORA, or A Realistic Open environment for Rapid Agent training. The goal of ARORA is to provide a high-fidelity, open-source platform for simulation, using physics-based movement, vehicle modelling, and a continuous action space within a large-scale geospecific city environment. Using four physics levels, or models, to create four different curriculum conditions for training, the SPL was highest for the condition using all physics levels defined for the experiment, with two conditions returning zero values. Future researchers should consider providing adequate support when training complex-physics vehicle models. The run-time results revealed a benefit for experimental machines with a better CPU, at least for the vector-only observations we employed.
通过使用深度确定性策略梯度算法测试各种物理级别来训练自动驾驶汽车导航,本研究填补了物理级别对车辆行为影响的研究缺失,特别是对强化学习算法的影响。研究了PointGoal导航任务的度量:模拟器运行时间、训练步骤和通过(归一化逆)路径长度(SPL)度量加权成功的代理有效性。训练和测试在新型模拟器ARORA中进行,即用于快速智能体训练的现实开放环境。ARORA的目标是提供一个高保真的、开源的仿真平台,使用基于物理的运动、车辆建模和大规模地理特定城市环境中的连续动作空间。使用四个物理水平或模型来创建四种不同的训练课程条件,在使用为实验定义的所有物理水平的条件下,SPL最高,其中两个条件返回零值。未来的研究人员应该考虑在训练复杂物理车辆模型时提供足够的支持。运行时结果揭示了具有更好CPU的实验机器的好处,至少对于我们使用的仅向量观察来说是这样。
