The calculation control models for the complex systems dynamic analysis have been suggested. The base method to develop methods with the increased reliability and effectiveness for solving complex system dynamic analysis tasks with a possibility to be implemented in the both common and distributed memory MCS has been chosen. The base approaches have been developed and the new algorithms have been created for increased reliability and accuracy numeric integration to solve complex object dynamic analysis tasks. Direct and indirect analysis algorithms for numeric integration methods have been proposed to reveal step and order selection optimality when using methods which make use of the calculation control algorithms. The non-linear objects dynamic analysis algorithms are implemented as parallel procedures as a part of NetALLTED circuit design complex on the NTUU "KPI" supercomputer.
