THE RESULTS OF IMPLEMENTATION OF THE LESLIE MODEL TAKING INTO ACCOUNT VARIOUS EPIDEMICS

We investigated the dynamics of changes in the size of an isolated population on the basis of P.H. Leslie's model. To implement the computational experiments applied programs were written in the environment of Delphi 7.0. The population size was predicted on the basis of three scenarios: 1) on the basis of the classical discrete model of P. Leslie, i.e. without taking into account the epidemic factor; 2) on the basis of the P. Leslie's model, taking into account the epidemic of the first type; 3) on the basis of the P. Leslie's model, taking into account the epidemic of the second type.
