Wow. Okay, I had this whole thing typed out and the forum deleted it. Hopefully I can remember and do this all again.
Been thinking about a way to make marketing work without killing the "little guy". The biggest problem, at least as far as I understand it, is marketing is difficult to implement because it would make the big airlines bigger, and make it even easier to squash the smaller airlines. So I came up with an idea that might just work. Below are the highlights of the system, then the formulas that I used to put it together, and then at the end, there's an attachment of a spreadsheet that displays the various information of this marketing system. So, now on with the description.
* Marketing System functions as a part of the ORS formula. This means marketing would have a direct effect on ORS. Keep in mind, the effect isn't actually based on the ORS system. It would be up to the programmer(s) to determine how to scale the effect.
* Airlines would pay for Marketing at individual airports. In this fashion, it is similar to the passenger terminal system that's used. Just as the terminal has an effect on the ORS, so does Marketing, and Marketing also is specific to the airport where flights originate.
* Airlines would pay for Marketing Points, which have a sliding cost scale dependent on the size of the airport the Marketing Points are purchased at.
* Costs and ORS effect are influenced by the number of flights an airline has originating at that particular airport. It is more expensive for an airline with 500 flights from one airport to buy a Marketing Point than it is for an airline that flies 100 flights from the same airport. This might seem counter-intuitive at first, but if you come to think of Marketing Points as advertisements (such as television, radio, and newspaper), a smaller airline would be much more efficient with its marketing budget, and, generally, would have a better grasp of advertising in the local area. Another way to look at it is the larger airline could need a larger advertising team.
Okay, those are the highlights. Here are the formulas and the spreadsheet to illustrate the idea.
MARKETING POINT = $2500 * ( AIRPORT SIZE ) * ( WEEKLY FLIGHTS / 10 )
In this formula, the "airport size" is the direct number of passenger demand bars for that particular airport. ORD would be 10. LIT would be 5.
ORS EFFECT = ( ( MARKETING POINTS * WEEKLY FLIGHTS ) - ( WEEKLY FLIGHTS^1.2 ) ) / WEEKLY FLIGHTS
It seems convoluted, but it brings everything down to an easily understood ratio between each calculation.
The attachment is just a spreadsheet that shows how the system would calculate out. Don't pay too much attention to the costs -- they aren't something to take literally. The formula that was used is easily adjustable when it comes to the size of the airport, and the actual cost of the Marketing Point.
Note that it actually has a negative effect if marketing is not used. It's not supposed to kill a flight (or an airline) to not use it, but there is drawbacks to not advertising your company.
If you have any comments about this, whether you think it would work, or what kind of gaping holes there are in here for exploitation... feel free to have at it. :)
