Abstract
An improved SIRS model is constructed as a supply chain risk propagation model, based on the actual situation that node enterprises are eliminated in the supply chain network. From the perspective of the small-world network, simulation is carried out to analyze the risk transmission mechanism in the supply chain network and the influence of various parameters on the supply chain risk transmission and the node enterprises in the supply chain network. Research shows that the process of eliminating node enterprises is also a process of supply chain network’s adjustment and gradual stability. In order to reduce the negative impact of this process on the supply chain network, node enterprises should take effective measures based on their own conditions to improve risk prevention capabilities, coordinate risk transmission, and enhance risk immunity, so as to improve the resistance of the entire supply chain to risks.

With the characteristics of innovation, synergy, win-win, openness, and environmentally friendly, the supply chain can promote cross-border and synergistic development of industries and is an important carrier to lead globalization to enhance competitiveness. e application of supply chain network is becoming more and more widespread due to the advancement of science and technology, the policy guidelines, and the trend of cooperation development among enterprises. e possibility of being affected by risks increases as the supply chain industry grows and develops
As global climate change scenarios have increased in recent years and climate effects have intensified, many supply chain companies must reassess the impact of supply chain risks due to natural disasters. e outbreak of COVID-19 in 2020 has left global automotive, machinery, communications, and other manufacturing sectors facing parts shortages, threatening supply chain disruptions within weeks and forcing delays in the launch schedule of new products
Chain risk management plays an important role in preventing risk infringement, responding to risk threats, and maintaining the stability of the entire supply chain network
Summary
With the characteristics of innovation, synergy, win-win, openness, and environmentally friendly, the supply chain can promote cross-border and synergistic development of industries and is an important carrier to lead globalization to enhance competitiveness. e application of supply chain network is becoming more and more widespread due to the advancement of science and technology, the policy guidelines, and the trend of cooperation development among enterprises. e possibility of being affected by risks increases as the supply chain industry grows and develops. E possibility of being affected by risks increases as the supply chain industry grows and develops. External factors such as natural disasters, public health emergencies, economic crises, and policy regulations and internal factors such as inadequate work quality of personnel, poor management system, and difficulties in capital turnover may become risk factors that induce problems and negatively affect the nodes in the supply chain, which in turn leads to risk transmission through the supply chain network path and further spread of harm. Erefore, supply chain risk has become a major factor limiting the development of supply chain management model and an important issue that companies have to consider in the implementation of supply chain management. Erefore, it is necessary to consider the study of supply chain operation where elimination exists, so as to more accurately understand the mechanism of supply chain risk transmission and supply chain changes. Us, the supply chain risk transmission mechanism is analyzed to provide a reference for defending the risk propagation into the supply chain network
