Problems solved by technology

[0004] At present, the construction of the deterministic model is mostly a differential equation, but the result obtained is relatively single, and the setting of various elements is weak
Although the network dynamics model is more convenient for setting various elements, it is difficult for these models to control the infection mode of individuals
Neither of these existing models satisfies our simulations of complex infectious diseases

Embodiment 1

[0028] Embodiment 1: as figure 1 As shown, a space-time dynamic simulation method of the disease transmission process, assuming that there are N individuals in an ecosystem, the total number of infection days is D, the infection threshold is IMAX, the healing threshold is CMAX, and the initial state of some individuals is 0. Represents not infected; the initial state of the rest of the individuals is 1, representing infected. As the number of days increases, the status of uninfected individuals remains unchanged at 0, and the status of infected individuals increases by 1 every day. The coordinates of each individual also increase the number of random numbers that obey the normal distribution every day. When the individual state reaches IMAX, it can infect uninfected individuals within its transmission distance. If there is an unaffected individual whose relative distance to this individual is less than the infectious distance, the unaffected individual is infected. When the...

Abstract

The invention relates to a novel simulation method and particularly relates to a space-time dynamic simulation method for the disease infection process. The method comprises steps that firstly, a database of each individual is established; secondly, a mobile coordinate information database for each individual is established; thirdly, whether a disease state reaches the infection threshold and thehealing threshold is determined, if yes, an patient is infected or cured; and lastly, the cured individual moves out of a system and no longer participate in various parts of the system. The method isadvantaged in that the integral infection method can be simulated, states of different individuals can be set, the state of each individual is simulated through the Monte-Carlo method, a problem thata single model can only simulate all the data and can not control elements is solved, and a new concept is provided for dynamic disease simulation.

Description

technical field [0001] The invention relates to a novel simulation method, in particular to a space-time dynamic simulation method of a disease infection process. Background technique [0002] Currently, in human society, the threat of infectious diseases is ubiquitous. Beginning with atypical pneumonia, many diseases have had a great impact on society. A very interesting question is when and how to control the outbreak of infectious diseases. The spreading process of infectious diseases is a complex spreading process of diseases among the population. If this complex process is modeled, it is possible to better learn the epidemic method of infectious diseases, understand its epidemic law, and predict its transmission process in order to intervene in it. [0003] It is a very common method to use mathematical models to help study the transmission mechanism of infectious diseases and predict the epidemic trend of infectious diseases. Research on mathematical models of infe...
