Technologies for multi-agent economic modeling with a complex system of connections

This paper is a continuation and development of the ECOMOD system for supporting the modeling of complex economic systems based on an open source platform. This article discusses the problems of automating agent-based modeling in the case of a system that includes both groups of similar agents and qualitatively different ones. A new system has been proposed to support the modeling of a system of interacting economic agents of a complex structure, including both ensembles of homogeneous agents and agents in the same role, but differing in internal parameters (households with different incomes can be savers or borrowers), as well as agents of a completely different nature (e.g. households and banks). This feature was not implemented in previous versions of the support system, but is a popular continuation, making it possible to describe both stochastic processes and a multi-product description of the economy. The application of the proposed approach is demonstrated using one economic model. The results of the work and important further steps in its development are discussed.
