This work attempts to achieve the image of cohesion by simulating the emergence of concentrations of population and its activities. This task is accomplished in coherence with earlier simulations operating with relatively simple procedure. It is consisted in sequential shifting of population primarily uniformly distributed and proportional activity loads. A modified intervening opportunities model is used and some parameter values observed and predicted are involved. The results encourage to some farther extensions of the procedure. The new approach involved few stimulating factors and self-supporting mechanism in order to ensure realistic diversification of initial territorial and functional predispositions. The next step is the introducing of a kind of self-training procedure which intends to achieve the compability of current and simulated sizes in a process of modification of parameter. That run of changes became a significant characteristic of particular zones. Subsequent operation brings forth a reverse process converting the current diversity into a uniform distribution. Those simulations both allow us, in a quantitative way, to estimate the ¡°labour¡± of the system needed to achieve the equilibrium as a ¡°steady state¡±. Some aggregations of primarily independent zones are involved together with the introducing of group selectivity affecting the big scale conditions of integrity.
