The technique of simulation of large loosely coupled systems based on the mathematical description of the system being modeled in the form of block-diagonal-lined structure. It is shown that the implementation of such an approach allows for the decomposition of the system, which leads to a significant increase in the efficiency of software as a cost required RAM, and the speed of solving the problem of modeling. The technique of the organization of computing process based on the data compression by moving to a compact form describing the sparse block matrix of individual subsystems.
