Kermack–McKendrick Epidemic SIR Infectious Disease Model - Metrics by Guy Lakeman
This is a simple SIR infectious diseases 3 stock model with Susceptibles, Infectives and Recovereds stocks. In the initial description the R signified Removed and could include Deaths, Recovered with immunity to infection (Resistant) or those who had fled the epidemic. Note the need to initiate the epidemic by adding a pulse of a single infected person at time 0.
Also applies to finance and war

The pharmaceutical supply
chain in Sri Lanka faces numerous challenges, including fluctuations in demand,
regulatory constraints, and logistical inefficiencies. This report aims to
develop a comprehensive model using system dynamics to understand and improve
the supply chain's efficiency and responsiveness. The primary objective is to
analyze the key dynamics influencing the supply chain, such as supply rates,
demand fluctuations, and inventory management, and to propose strategic
insights for optimization.
