Abstract: Aiming at the deficiency of influential resources identification indicators evaluation in manufacturing system,an evaluation method based on virus propagation model was proposed.By taking the top-10 manufacturing resources of several typical influential nodes identification indicators as the influential manufacturing resources,a network model of the manufacturing system was built.Different influential nodes identified between comprehensive evaluation indicator and other indicators were selected as the initial infected nodes of virus propagation model's simulation,and the trend between the quantity and quantity increment of infected nodes and spreading time was compared to evaluate the performance of those indicators.Each node appeared in the top-10 ranking list of each indicator was used as the initial infected nodes of virus propagation model's simulation.A ranking list based on virus propagation model could be obtained through the simulation and viewed as the evaluation standard.Indicators' performance could be assessed through calculating the number of common nodes and Kendall Rank correlation coefficient between the ranking lists of this standard and those influential nodes identification indicators.Indicators' performance under different fault propagation probability could be judged through changing the infection rate of virus propagation model.The interior assembly line was taken as an example to verify the feasibility of the proposed method.
