I've got a twist to Swiftus' Commonality Points idea, which I think is radical enough to warrant another topic...

To start, let me remind you what the original idea was:

Okay, so I am up EARLY this morning.

I thought of a way to possibly change the way you look at commonality. This applies only for Fleet and NOT engine commonality

You get 1 point for your first aircraft fleet type.

You get 1 point if you get another aircraft from the same manufacturer of the same size/type (For instance, adding the 737ng to your 737c fleet)

You get 2 points if you get another aircraft from same manufacturer if type is different (For instance, adding 757s to your airline of only 737s)

You get 2 points if you get another aircraft from same manufacturer if size is different (For instance, adding the 747 to your airline of 737s)

You get 3 points if you get another aircraft type from a different manufacturer if size is the same (For instance, adding a A320 to the 737s)

You get 4 points if you get another aircraft type from a different manufacturer of a different size (For instance, adding A340s to the 737s)

When you click to view another airline, their total number of points would be public and is displayed there.

The more points that you have, the more your fleet will cost to operate.

There are many reasons I like this system.

1. You get penalized less if you are staying with one plane type (MD80/737)

2. You get penalized more if you are getting planes from everyone

3. You get penalized more if your airline is too broad (meaning, flying Pipers through Jumbos). This will help small airlines who want to fly only small a/c

4. This will prevent F5 spammers from going after everything as this will severely impact an airline early on.

So my idea:

My idea breaks fleet commonality into 3 types of points: manufacturer, size of plane and # of planes operated

First, you get points for size:

You get 1 point for your first small fleet

You get 2 points for each subsequent small fleet

You get 3 points for your first medium fleet

You get 6 points for each subsequent medium fleet

You get 5 points for your first large fleet

You get 10 points for each subsequent large fleet

You get 7 points for your first very large fleet

You get 14 points for each subsequent very large fleet

You would just multiply the amount of points by a set variable.

Then, you get points for manufacturer:

You get 3 point for your first fleet's manufacturer

You get 6 points for your second fleet's manufacturer

You get 10 points for your third fleet's manufacturer

You get 15 points for your fourth fleet manufacturer

etc.

You get 3 point for each subsequent fleet from a manufacturer which you already have a plane of.

Once again, you would just multiply the amount of points by a set variable.

Finally, you get points for the # of planes you have in each fleet.

You would get 1 point for your first plane of each fleet

You would get .5 points for each additional plane you have

Once again, you would just multiply the amount of points by a set variable.

Some examples of how commonality costs would look if you used this method:

Let's say that the variables are $150,000 per point for size, $200,000 per point for manufacturer, and $250,000 per plane point

First of all, an airline using a fleet of 10 A320s and 10 A340s

This airline would have 12 size points, 6 manufacturer points, and 11 plane points.

Their total fleet commonality cost would be $6,750,000.

For contrast, an airline using a fleet of 5 A320s, 5 MD-80s, 5 B777s, and 5 A340s.

This airline would have 36 size points, 22 manufacturer points, and 12 plane points.

Their total fleet commonality cost would be $13,800,000

That's a pretty drastic difference, and would make it much more profitable to run the first operation than the second.

A similar system could be employed for engine commonality.

Thoughts?
