Abstract: This paper introduced the current situation of biomedical cold chain logistics in China, finding that many of them have to be shipped with specific logistics surroundings to guarantee the quality. But there are only a few logistics enterprises under the permission of government, who - have to afford the distribution of all the country. This decides another feature of biomedical cold chain logistics - multi-variety and small volume with low profit. In order to save the cost and improve efficiency, this paper proposed a new distribution path selection method for biomedical cold chain: Bidirectional Dijkstra Algorithm. This paper also designed a table calculation method to further simplify the application of this method. Finally, this paper analyzed the application and limitations of this method in biomedical cold chain logistics area.


Keywords: Biomedical products, Cold chain, Distribution path, Paths optimization, Bidirectional Dijkstra algorithm.
