The present invention discloses a vaccine
cold chain distribution method and
system based on
big data analysis, which relates to the technical field of
big data analysis, including integrating information resources of vaccine
cold chain, screening and verifying, constructing a multi-objective optimization model, predicting cost, time and carbon emissions, formulating a multi-
modal transport plan based on the prediction results, finding the shortest
route, and designing a logistics
relay plan. During distribution, once an emergency occurs, an alternative
route is generated until the distribution is completed. By integrating and verifying vaccine
cold chain information,
data accuracy is improved, the multi-objective optimization model balances cost, time and environmental factors, and promotes the refined
greening of distribution strategies. Multi-
modal transport supported by GIS and algorithms ensures efficient management of paths and
temperature control, accelerates logistics response, and the emergency alternative
route mechanism ensures supply chain resilience, jointly promoting the vaccine supply chain to be efficient, economical, green, and have strong
emergency response capabilities, and ensuring that vaccines are distributed safely, quickly and
environmentally friendly.
