Emergency service modes of supply chains with replenishment sources
With the threat of global bioterrorism, it is necessary to establish a scientific and reasonable system of emergency rescue supplies reserves and distribution, which can be benefit to form an effective emergency logistics network, to shorten the radius of emergency rescue. In the anti-bioterrorism system, a system of emergency service in a supply chain can be formed from the reserve and distribution of emergency rescue supplies, and it can be divided into replenishment source and non-replenishment source because of the geographical differences. The efficiency and cost of emergency rescue system have been discussed systematically in this paper, based on the analysis of the relationship between the amount of emergency rescue supplies reserves and the vaccination rate. Furthermore, the paper has proofed the influence of replenishment source on the service efficiency and cost of supply chain through numerical simulation.
