The System Architecture identifies all the products (including enabling products) that are necessary to support the system and, by implication, the processes necessary for development, production/construction, deployment, operations, support, disposal, training, and verification

System : Abstraction

• System : Abstraction

• Functional model
• Dynamic model
• Semantic Model
• Object model
• Physical Model
• Interfaces Model

• Model Views

The Functional Architecture

• The Functional Architecture

• identifies and structures the allocated functional and performance requirements.

• The Physical Architecture

• depicts the system product by showing how it is broken down into subsystems and components

Functional : Discover the system functions

• Functional : Discover the system functions

• Washing Machine

• What it does ?
• Washes
• How it does ?
• Agitates
• Physical Component : Agitator

How to fly ?

• How to fly ?

• Look at birds: Physical Model

• So I need: Legs, Eyes, Brain, and Wings.

• But I can not fly !!!

• Why ?

• I have to find the flight functional model !

Functional decomposition of flying function:

• Functional decomposition of flying function:

• Produce horizontal thrust,
• Produce vertical lift.
• Takeoff and land,
• Sense position and velocity,
• Navigate,

Physical decomposition:

• Physical decomposition:

• physical components that birds used to fly: Legs, Eyes, Brain, and Wings.

• But can not be applied to system directly

Multi-criteria decision-aiding techniques are available to help discover the preferred alternatives.

• Multi-criteria decision-aiding techniques are available to help discover the preferred alternatives.

• This analysis should be repeated, as better data becomes available.

Integration means bringing things together so they work as a whole.

• Integration means bringing things together so they work as a whole.

• Interoperability means loose coupling between components thus flexibility

• System-of-systems paradigm deals with temporary loose coupling and emergent behaviour

Integrate :

• Integrate :

• Build the system

• Verification :

• Ensures that you built it right

• Validation :

• Ensures that you built the right thing

• Certification :

• Ensure that the system is safe

• Acceptance :

• Ensures that the customer gets what he wants and the company get paid.
