Computer Design Tools

Numerous software packages are availablefor the design of engineered devices and

structures:-CADCAM (Computer Aided DesignManufacturing)-Circuit Analysis-Structural Analysis-Finite Element Analysis-Others

These all serve to allow engineers towork more efficiently and to help takeaway tedious aspects of engineers work.

However, the use of this type of software also leads to ethical issues.


9/16

Who is responsible when a flaw in softwareused to design a bridge leads to the failure of the bridge????


10/16

Engineers must be careful to make sure that thesoftware is appropriate to the problem beingworked on. They should be knowledgeable about the

limitation of a software package. They must keep up to date on any flaws that havebeen discovered in the software and ensure thatthe most recent version of the software is being

used. Its important to verify the results of a computer-generated design or analysis.

What can engineers do to avoid like these problems???

Integration of Computers intoEngineered Systems

Computers have become a component of manyengineered systems.

For example, modern automobiles contain multiplecomputers dedicated to specific tasks which allow

them to operate more efficiently and safely.


12/16

What the disadvantage of computerized systems??

The ability to control aspects of systemperformance using software removes humans fromthe control loop.

-Many computerized systems malfunctionwithout giving the operator any indication that aproblem exists.

-The operator is unable to solve any problembecause the software design doesnt allow it


13/16

The solution:

Its essential when designing systemswith embedded computers andsoftware that engineers ensure thatsoftware is adequately tested thathumans can intervene when necessary


14/16

The ability of a computer to makedecisions without the intervention

of humans.


15/16

are weapons capable of completinga mission with limited or no

human intervention.

Autonomous

Weapons

Require control at frequentintervals

Manufacturingprocesses

For running a spaceshipSpace flight


16/16

Its clear that Autonomous Computers cangreatly increase productivity andefficiency in many areas.Ultimately there must be some human

control in order to prevent disasters
