Description

The paper presents several models of the Bering Sea ecosystem. The models differ in the degree and method of grouping. The use of the multimodal approach to research of ecosystems makes better use of available information about the object. The system is considered in two ways: as a closed object and given the influence of the environment. Equilibriums of the system were examined for stability. A comparison of the solutions of the aggregated model with the dynamics of the original model is performed.

Modelling of ecosystem with different types of components aggregation

The paper presents several models of the Bering Sea ecosystem. The models differ in the degree and method of grouping. The use of the multimodal approach to research of ecosystems makes better use of available information about the object. The system is considered in two ways: as a closed object and given the influence of the environment. Equilibriums of the system were examined for stability. A comparison of the solutions of the aggregated model with the dynamics of the original model is performed.
