Work is devoted to research of stability of complex technical systems, objects of the chemical industry, at their hit in conditions of external influences (force-majeur circumstances) with use of computer models of system. Any system is subject to influence of external impacts. It is important to know, how long the system is able to carry out the functions (i.e. to keep functionality) at the damages received as a result of impacts. The model of distribution of pulse impacts on system which has allowed to reveal the strongest and weak places in its structure is offered. The model allows to estimate stability of an element of system its position in structure.
