Older western missiles tend to use pure semi-active radar homing. Pure command guidance is not normally used in modern surface-to-air missile (SAM) systems since it is too inaccurate during the terminal phase, when a missile is about to intercept a target. This is because the ground-based radars are distant from the target and the returned ...
Command-and-control management is categorised by systems thinkers as the dominant method of management in the Western world. Key influences are said to include Alfred P. Sloan, Henry Ford, James McKinsey of the eponymous accounting firm, and Frederick Winslow Taylor.
Real-time Control System (RCS) is a reference model architecture, suitable for many software-intensive, real-time computing control problem domains. It defines the types of functions needed in a real-time intelligent control system , and how these functions relate to each other.
Command and control (abbr. C2) is a "set of organizational and technical attributes and processes ...[that] employs human, physical, and information resources to solve problems and accomplish missions" to achieve the goals of an organization or enterprise, according to a 2015 definition by military scientists Marius Vassiliou, David S. Alberts, and Jonathan R. Agre.
For example, array with constant-time access and update is a basic component of most imperative languages and many imperative data-structures, such as hash table and binary heap, are based on arrays. Arrays can be replaced by map or random access list , which admits purely functional implementation, but the access and update time is logarithmic .
Two basic requirements are regulation (disturbance rejection – staying at a given setpoint) and command tracking (implementing setpoint changes). These terms refer to how well the controlled variable tracks the desired value. Specific criteria for command tracking include rise time and settling time. Some processes must not allow an overshoot ...
Planned economies contrast with command economies in that a planned economy is "an economic system in which the government controls and regulates production, distribution, prices, etc." [39] whereas a command economy necessarily has substantial public ownership of industry while also having this type of regulation.

Global Command and Control System (GCCS) is the United States' armed forces DoD joint command and control (C2) system used to provide accurate, complete, and timely information for the operational chain of command for U.S. armed forces. "GCCS" is most often used to refer to the computer system, but actually consists of hardware, software ...
