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.
