Cognitive domain information transmission HISR model and its transmission characteristics with mathematical simulation

Abstract

Objective To construct a theoretical model for cognitive domain information transmission (COIT) to promote the establishment of an attack and defense system for COIT, and further to validate it by simulating data in mathematical model. Methods A hub-susceptible-infected-recovery (HSIR) model was proposed theoretically to conceptualize COIT, and then the model was validated with Runge-Kutta nonlinear integral equation for mathematical simulation. Results Standard HSIR model showed when cognitive domain information was transmitted in a large population of 10 000 people, the peak transmission was observed at Day 46 and 7 480 members were covered, with a basic reproduction number of 1.3. Further, when some measures were taken to obstruct COIT at Days 8, 4 and 2, respectively, the number of peak infects people was decreased to 5 822, 4 892 and 4 126, with a peak transmission duration shortened by 92, 62 and 41 d, in order. Conclusion Basing on HSIR model, we bring forward a dynamic model of COPT, and primarily construct a defense system of COPI combat.
