First, this paper uses the Lyapunov stability function to construct the time-space implicit calculus equation model of the integrated manufacturing of single-chip microcomputers for the abnormal diffusion phenomenon. Secondly, we use the differential data fusion algorithm modeling of the discrete manufacturing system and introduce the implicit calculus equation modeling method. Finally, the article uses the singular boundary method to give the simulation results. The study found that the implicit calculus equation modeling method is simpler than the existing model, and the physical and statistical concepts are clear.
