4. Type 1 - Systems
Open System – Interacts with its
operating environment through inputs
and outputs across the boundary
Closed System – Isolated from its
external environment

External element
External
Interface (I/O)
5. Type 2 - Systems
Natural System – contains natural
elements – result of natural processes
Human Made System – contains
human-made /natural elements
adapted to human designed purposes
Human Modified System – natural
system modified by human

6. Type 3 - Systems
Physical Systems– exists in a physical
form
Conceptual System – do not have
physical form
6Dr.P.Karthikeyan, Associate Professor – IT, TCE, Madurai
7. Type 4 - Systems
Precedented System – has been
produced before
Unprecedented System – has not been
produced yet. It requires research and
development.
7Dr.P.Karthikeyan, Associate Professor – IT, TCE, Madurai
8. “ Systems engineering is
applied to open,
physical systems that are
human-made/modified
from largely
precedented elements

▪ During Rain/Snow/Fog
▫ Wings - subsystems
▫ Radar – subsystems
▫ Engine - subsystems

11. System as a Product
In a physical sense, the term “System” considered as
“Product”
The outcome of a system may be a product or system
delivers product.

Development product
Test product
Training product
Disposal product
Support product
13. System – Operational Capability
Systems are much
more than an
aggregation of
Hardware and
Software products
Also include
Organisation,
personnel, collective
training systems,
facilities, data,
support, operating
procedures and
policies
13Dr.P.Karthikeyan, Associate Professor – IT, TCE, Madurai
14. Aircraft System Capabilities
14
▪ Personnel – air crew operation
▪ Support – maintenance
▪ Facilities – terminals
▪ Org. policies – operate system
▪ Collective Training – air crew & ground
crew
▪ Data – specification to operate
▪ Major equipment – HW & SW

15. System – Descriptions
System can be described
in two broad ways
Logical (functional)
▪ What it will do
▪ How well it will do
▪ How it will be tested
▪ What condition it will
perform
▪ What other systems
will be involved
Physical
▪ What are the system
elements
▪ How they look
▪ How they are to be
manufactured,
integrated and tested
