Many systems optimize phase by phase through a very long period of time because of multi-particle invisible entity processes entangle in system global variables. When system confront with breakdown then system variables need optimization. System would protect, predict, and respond to changes in environments when optimization conduct according to changes cross system platform.
Systems owners expect to have either capital lost or human lost when system has some key operational issues. Errors exam, local variables can modify and then system improves through various processes; nevertheless, errors may occur again. Systems owners are not quite sure if system can handle errors in long run because of high number of invisible entities in global variables.
