Cafeteria Simulation using M/M/1 Queueing System

―How to Avoid Crowding, Closeness, and Hermetically in the Covid―

Abstract

　We believe that the risk of infection in a student cafeteria is the change of conversation and location without a mask in "crowded," "close," and "enclosed" situations. We consider it important to provide ventilation for “closed” and to install acrylic partition panels for “close” situations.

　However, in a “dense” environment, when there are large numbers of people in one room, the risk of infection increases. (e.g., cafeterias, libraries, etc.)

　In this study, we examine how "crowding" can be avoided by simulating the current use of student cafeterias using a queue.
