论文摘要
共同19-19大流行造成了前所未有的破坏，尤其是在零售中。如果无法在网上满足基本需求，或者在放宽了更严格的措施的地方，客户必须亲自访问商店场所。这自然会引起易感人（客户或员工）被感染的风险。在保留商店的经济可行性的同时，尽可能最大程度地降低这种风险。因此，我们探索和比较了Covid-19在涉及人与人之间互动的不同购物情况下的传播：（i）自由流动的，非结构化的购物； （ii）结构化购物（例如队列）。我们检查了（i）或（ii）中哪个是最小化covid-19在给定商店中的传播的优点，但要受到诸如商店几何形状之类的限制；人口符合当地准则；以及商店组织者可能可以使用的其他安全措施。我们得出一系列结论，例如单向自由移动比双向购物更可取，并且只要可以很好地保护它们免受感染的保护，就应该最大化服务器的数量。
The COVID-19 pandemic has caused unprecedented disruption, particularly in retail. Where essential demand cannot be fulfilled online, or where more stringent measures have been relaxed, customers must visit shop premises in person. This naturally gives rise to some risk of susceptible individuals (customers or staff) becoming infected. It is essential to minimise this risk as far as possible while retaining economic viability of the shop. We therefore explore and compare the spread of COVID-19 in different shopping situations involving person-to-person interactions: (i) free-flowing, unstructured shopping; (ii) structured shopping (e.g. a queue). We examine which of (i) or (ii) may be preferable for minimising the spread of COVID-19 in a given shop, subject to constraints such as the geometry of the shop; compliance of the population to local guidelines; and additional safety measures which may be available to the organisers of the shop. We derive a series of conclusions, such as unidirectional free movement being preferable to bidirectional shopping, and that the number of servers should be maximised as long as they can be well protected from infection.
