In my AHP table I wanted to make it apparent with my comparisons to the other listed criteria
that maintaining car functionality was paramount in my solution algorithm. I don’t want to
reinvent the wheel or make whole new cars, I want to make sure that the original functionality
remains the same and the solutions posed will not impact it; at least not noticeably. Also, while
co2 emissions are important to the problem, money saved in the long run is a more desired trait.
Decision Matrix:
The two solutions I am comparing are Automatic Engine Start/Stopping programs, and
swapping out original parts for fuel efficient/hybrid engine parts instead.

These numbers I decided on were due to the fact that both are good, but overall, the more fuel
efficient engines surpass the automatic start/stop program in every criteria that I listed as
important.
Conclusion:
As a customer, in general regards to the solutions I collected (I was late on my assignment so
no students replied to my post, apologies.) I found that automatic start/stop functions to engines
would help in the short term, however, if every gas powered engine in the world today were to
be swapped for a hybrid solution, the vehicle wouldn’t rely on the gasoline to power the car
while it's idle. When the car is not expected to move at high speed, gasoline is not used; just like
in the hybrid cars we have today. Not only would this proactively save money by not burning
gasoline in idle, but it would also allow gasoline free driving at slower speeds such as on city
streets, and only using gasoline in fast pace environments like highways. In my eyes, it’s an
overall much more efficient solution in the long run based on my decision matrix.
