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.
Sub-Systems
- 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
- 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.
