Simulation study on supply chain stability under drug market demand changes
Based on the main nodes of the pharmaceutical supply chain,including raw material production,drug production,and healthcare institution procurement,a system dynamics model was established to investigate the variations in supply at each node under different patient demand conditions.Simulation of market demand models with transition function changes,periodic function changes,and stochastic function changes was conducted to analyze the different effects on the stability of the supply chain.It is recommended that supply chain planning should flexibly adjust strategies according to demand changes to ensure the stability of drug supply and meet patient demands.
