The Analysis of Defect Emergence in Assembly Process Based on the Discrete-Time SIRS Model

In this paper, the emergence phenomenon in the assembly process was studied. First, we constructed the SIRS model of the assembly process and obtained the threshold condition of the extinction of defects through phase trajectory analysis. Second, we discretized the SIRS model and studied the emergence phenomenon during the assembly process. Third, the screening process was added to decrease the basic reproduction number in the SIRS model. It showed that the propagation of defects and emergence phenomenon could be suppressed to some extent through simulations. Finally, we found the relationship between the critical time point and other parameters during the assembly process, which is helpful for the assembly process.
