WHAT IS IT?
This project's objectives were achieved successfully by creating a simulation that captures how COVID-19 is transmitted from person to person in a restaurant setting. This includes transmission through viral aerosol particles, respiratory droplets, and fomites. The simulation also allows for COVID-19 safety measures such as physically distanced tables and face masks to be implemented. The output data can be analysed to gauge how effective a safety measure was, based on how significantly it reduced probable infections and infection risk. A combination of safety measure can also be tested to create the greatest reduction in infection risk.
HOW IT WORKS
(what rules the agents use to create the overall behavior of the model) customers will enter the restaurant and take a seat, and waiters will served them by periodically approaching their table to simulate a real life restaurant service such as taking orderrs, clearing plates ect. A table of customers will enter the restaurant every 300 ticks and sit at an empty tasble. they will remain in the restaurant for the duratino of booking time. when the service lim,it is exceeded, the customers will stop spawning and will begin to filter out of the restaurant.
all mobile agents have the chance of being infectious, set but the slider in the virus emission controls section. infectious agents will output aerosol particles into the air within the boundaries of the restaurant.
the higher the volume, the greater the number of particles produced.
symptom severity can be altered through the adjustment of coughing and sneezing frequency. a large number of aerosols are produced by these events, expecially sneezing.
sucsepitble agents will inhale the aerosol particles and their infection risk will be increased. the infectious code of covid is unknown but is estimate to be roughly 300 particles. once the agents infectious risk reaches over 300, they are likely to develop an infections
HOW TO USE IT
setup
Following the numbering of the sections, enter the values that you wish to test, starting with setting the general controls, then infection controls, and lastly the ventilation controls (numbered)
Click the setup button at the top left of the screen to setup a restaurant with the values you have entered.
Familiarise yourself with what the agents are using the legend.
To begin the simulation, click the 'Run Simulation' button
runtime
depending on the experiment, you may wish to alter parameters during the simulation. It is possible to alter parameters like view controls, personal protective measures and ventilation controls during the simulation.
if manual-customer-spawn is on, to seat customers at the selected table, click the middle of the table. It may help to click several times.
To infect a customer, waiter, or bartender, it is advisable to slow the simulation down using the slider in the interface heading tab. This will slow the movement of the agents to help you target them. To infected them you must click on them/the patch that they are on.

Average risk of infection graph: show the average risk of infection of all aagents at a given tick
no.of probable infections: the number of probabl infections produced so far into the simulation
% of probable infection: the percentage of people in the restaurant who have been infected
General output data:
Current Seating Area Occupancy: total count of everyone currently in the restaurant
Floor staff: the number watiers and bartenders
total customers served: the total number of customers served so far
total of infectious peoplle through service: the total number of infectious people who have been in the restaurant
infectious currently: the number of currently infectious people in the restaurant
THINGS TO NOTICE
THINGS TO TRY
if you want to, you can click on a table and customers will sit there, or you can click a mobile agent and they will becom infected
try opening the windows and observe the flow of aerosol particles
trying using the view controls
EXTENDING THE MODEL
- load in restaurant from file
- click to create restaurant by placing tables etc manually
- save a specific configuration
- save a specific ordering of customers for re-testing
- further physicaly distancing, customers choose a seat far away from other tables
- wind directions and wind speed
- one-way system
- use of washroom
- portable fans to accelerate air flow
- adjust booking arrival intervals
- queue system
- reduced waiter contact
- more realistic dissipation of virus particles from breathing coughing etc
