Simulation Modeling of Post-Earthquake Vaccine Cold-Chain Emergency Transportation Based on ExtendSim

Abstract:

Emphasizing the emergency state of post-earthquake epidemic and delivering sufficient quantities of vaccine to the affected areas in time cast a great significance on prevention and control of epidemic. This paper focuses on optimization problem of anti-epidemic vaccine cold-chain emergency transport processes. In the first place, we construct and optimize transport processes with the help of vaccine cold chain logistics theory. Then we assume WenChuan Earthquake as background, with an example of health and epidemic prevention work of the earthquake-stricken city and the surrounding county of A (X County), and utilize ExtendSim to establish the model. Results show that at the same period, cold chain of optimized ‘Network Parallel’ supplies almost forty times as many as former type of ‘Tandem’ does in delivering vaccine to earthquake-stricken places and that optimized cold chain maintains homeostasis.
