Аннотация:The article analyzes the presence of common components in the models of interaction between ethnic groups and models of drive heating. It is determined that some of the components of these models are similar. Analysis of models allows you to select the com- ponents of the same type. The same components, the effect of heterogeneous models to each other and to a single process simulation. The conclusion about the need to consider this factor in the development of simulation systems ethno-social processes. The proposed approach will signifi cantly improve the accuracy of forecasts and make effective use of social technologies
