Abstract:

In order to control the risk of the vaccine supply chain, a vaccine supply chain risk evaluation index system was constructed. Firstly, based on the SCOR model and total quality management theory, the initial set of vaccine supply chain risk factors was determined. Secondly, using grey correlation analysis and rank correlation methods, the initial set of risk factors was screened and simplified to construct a vaccine supply chain risk index system. Finally, the rationality of the index system was verified by using the principal component-information entropy method. The results show that the risk evaluation index system of the vaccine supply chain constructed in this paper contains five primary indicators of planning process risk, procurement process risk, production process risk, distribution process risk and return process risk, as well as 20 secondary indicators such as the accuracy of supply and demand forecast. The risk evaluation index system reflects 83% of the risk information of the vaccine supply chain with only 69% of the indicators, which is scientific and rationable.

Key words: vaccine supply chain, risk evaluation index system, grey correlation degree, rank correlation, supply chain operation reference (SCOR) model
