- Abstract
- The technique of simulation loosely coupled systems based on the mathematical description of the system in the form of block-diagonal-lined structure. It is shown that the implementation of such an approach provides a significant efficiency uvelichknie software costs required RAM, and the speed of solving the problem of modeling. Sets the method of construction of the computing process based on the compact form of description block sparse matrix of individual subsystems in a fixed row-column format. To be able to take account of new nonzero elements in a compact description of the simulated system is proposed to use a two-stage procedure for the formation of such a description and provides the realization of a two-stage process procedure diagonal block matrices based on the stages of symbolic and numerical analysis.
