This work builds a macro model for livestock farming based on aggregation of initial micro description for rational control of total number of vintage livestock (age cohorts). Solution of an optimal problem on cohort total number of livestock gives the age limit for the operation of animals, the...

This paper presents new results of mathematical modeling of economy and environment interaction. A model of mutual interaction of livestock farming - one in a two main agricultural branches - and natural pastures that are the essential part of livestock farming forage reserve is proposed....

This work builds a macro model for livestock farming based on aggregation of initial micro description for rational control of total number of vintage livestock (age cohorts). All variety of animal kinds is reduced to one by given recount coefficients. An optimal problem on co-hort total number...

A multi-agent model is proposed for the analysis of self- organization of trade networks. The model takes into account time spent on transactions (`` trade distance). It is shown that the same set of traders may generate trade networks of different structures depending on average trade distance....

We present a natural generalization of the Dixit-Stiglitz monopolistic competition model (DSM) | we assume that there is a continuum of industries, each of them described as in DSM, and each characterized with its own elasticity of substitution. Although rms in all industries share the same...
