Centralized and decentralized control system structure

System owner determines and select an optimal control system structure for system performances. The reciprocal relationship between centralized and decentralized structure offers to system framework when system resources cannot maintain an optimal balance between internal resources and external forces. These two instances improve poor balance and low performance in system environments.
Invisible entities expand in internal and external system environments when system owner transforms pattern structure back and forth between centralized and decentralized mode.
System owner has awareness about global variables modification and consequence of changes on entire system environments but system elements and external forces may not have a holistic view of postural pattern alterations. Most system elements encounter with complexity when system behavior modifies through new pattern structure.
System owner supposes to measure and anticipate complexity among system elements and external environments prior selection of an optimal control system. Wrong presumption in system analysis hints inappropriate control system implementation in global variables. Unfit strategy patterns for control system structure can cause low accountability in system performances; besides, system resources and external forces would confront with low adaptability and interoperability in the new structure mode
Between centralize and decentralize mode can implement many instance levels in control system structure.
Observation: The control system conversion corresponds to a new model culture system for elements in an operational system; therefore, the conversion state on control system has been illustrated that complexity hits almost many elements in system platform.
