Complex System, Sub-System and Control Diagrams

Complex Systems

Complex systems are composed of numerous interconnected parts, all of which work together to perform a common function.
These systems are often broken down into simpler sub-systems to be understood and analysed more effectively.
Understanding complex systems requires a good grasp of the underlying sub-systems and their interactions.
Examples of complex systems can include a computer, a nuclear power plant, or the human body.

A sub-system is a system within a larger complex system that performs a specific task.
Sub-systems are often designed and analysed independently but always work in tandem within the larger system.
If one sub-system fails, it may affect the performance or functionality of the whole system.
Understanding the role of each sub-system and their interconnections is crucial when studying complex systems.

Control diagrams or schematic diagrams are graphical representations of the components and interconnections within a system.
These diagrams can depict the flow of signals, energy, or materials through the system.
They provide a clear, visual representation of how a system operates at a high level.
Key elements in control diagrams may include input and output variables, process components, and control devices.
Mastery of control diagrams is essential when trying to understand or design complex systems.
