Interesting Multi-Row Macro - Any help appreciated!

Hey all!

 

I'm currently using Alteryx to create a model to analyze bus routes in the U.S., and have an interesting idea I would like to implement, but am confused on how to do so. 

 

I've created a model that takes a list of possible bus trips (i.e. Washington D.C. to New York to Boston/Philadelphia to New York) and along with a score of how likely a passenger is to travel that trip on that route. My model predicts a certain number of passengers will travel that route over a period of time, and I have actual seat numbers for each route as well.

For bus trips where predicted passengers are greater than capacity, I'd like to reallocate them to lower "scored" trips. For example: 

  • From the first row we now we have 400 passengers to reallocate who are traveling from Boston to Philadelphia
  • We could put all 300 of them on the trip right below because there are seats available, but I think that's unreasonable - I don't know how many passengers are on each segment of the trip (BOS-NYC and NYC-PHL)
  • Instead, I'd like to only put as much of their capacity as their share of score would suggests (i.e. 400 * .22= 88 passengers) and puts "388" into the reallocated passengers column.
  • There are remaining passengers that could be allocated (400-88 or 312), and the next row has additional passengers to spill (50), so now there are 362 potential passengers to spill then
  • This process repeats (i.e. you attempt to spill passengers to the next row) until the "route" ends in the data, and begins again on a new route (in this case DCAPHL)

 

I imagine this involves a combination of the running total and multi-row tools, but wanted to get some advice as an Alteryx beginner. My sample data is below and any advice you could provide would be appreciated!

 

Best,

-Shay
