cet-1029	Zhang, Xuqi	Research on Risk Early Warning of the Chemical Supply Chain Based on Improved PSO Algorithm 	2017	6	.pdf	application/pdf	3028	183	59	Chemical risk early warning indicator system can reflect all kinds of risks while reflecting the real situation of supply chain risk accurately and sensitively. Figure 4: The result of the output value and the expectations It can be seen from figure 3 that the prediction accuracy of supply chain risk is more than 90% by using the improved PSO algorithm.	cache/cet-1029.pdf	txt/cet-1029.txt
