The offered 100 mathematical models and supporting them 35 software  tools complexes (M&STC) are purposed for a systems analysts from customers, designers, developers, users, experts of testing laboratories and certification bodies, as well as a staff of quality maintenance for any complex system etc. M&STC are focused on providing system standard requirements on the base of modeling random processes that exist for the life cycle of any complex system. Models implement original author’s mathematical methodology based on probability theory, theory for regenerating processes and methods for system analysis.  M&STC may be also used in training and education for specializations "System engineering", "Software engineering", "System safety and security",  "Information systems".
