3. Universal Systems Model is an attempt to graphical depict processes of all sorts.
Viewing something through the scheme of the universal systems model is an attempt to simplify something that is relatively complex.

4. Universal Systems Model is an attempt to graphical depict processes of all sorts.

Output
Feedback

5. Diagramming your system
Sample system
Read the 4 scenarios
Use your notebook paper to identify the 4 components of USM
2. Select ONE scenario and diagram it- Use the construction paper.

6. Open-loop versus Closed-loop
Open-Loop System Systems are found in nature and some are made by humans.
Closed -Loop System
A system that uses feedback from the output to control the input.
A control system that has no means for comparing the output with the input for control purposes. Control of open-loop systems often requires human intervention.

9. Input
The ideas and activities that helps us determine what we want to accomplish.
Tools and Machines
People
Time
Capital
Information
Finances
Energy
Materials

11. Describing Resources
People- People are the creators of technology and use the other resources that have been around billions of years, to create technology.
Information- Technology requires information. It is use of that information that helps us to meet our needs and wants.
Capital- Any form of wealth is capital. Capital is barter, money, credit, or property.

12. Describing Resources Cont.
Materials- Materials are the goods that we develop into products.
Tools and Machines- Tools include hand tools and machines.
Energy- Energy is the source of power for all of our technology systems.
Time- Since the industrial era, time has been measured in hours, minutes and seconds. Our forefathers measured time the setting and rising of the sun. We now measure time in nanoseconds (billionths of a second).

13. Process
The conversion of your ideas through the use of the 7 resources into useful products.

14. Output The result of the system. Desired: goods Undesired: pollution
Expected
Unexperted

15. Feedback-
Provides information about the quality of what is being produced
Monitoring the system using gauges, displays, and sensors to do. Monitoring the systems making changes as needed.

16. Communication Systems – Systems that change information into messages that can be transmitted. These systems include a sender, message, receiver, and feedback.

17. Structural Systems - Systems that use goods and materials to build structures that will resist external force, support a load, and hold each structural element in a relative position to other parts.

18. Manufacturing Systems – Systems using materials and processes to produce usable products.

19. Energy, Power and Transportation Systems – Systems that convert energy into mechanical, fluid, electrical, radiant, chemical, and thermal energy.
