    Data Cross Checking from imported online poll

    Hi,

    I'm trying to create a schedule in Excel based on the team's availability imported from Doodle.

    I have attached the documentDoodle 16.xls and I will try to explain my thought process in steps. Hopefully you'd be able to help me translate this into a coherent spreadsheet.

    Step 1 - Availability - poll sheet

    I have imported a spreadsheet from Doodle, containing the team's availability.

    Step 2 - Cross Check sheet

    I would manually cross reference pairs of two based on their availability. For example, the first two on the list are unavailable on the same shift three times.
    Then I'd fill in another table with the results of this cross reference, manually, trying to find the best matches, the pairs of two team members that have the least overlaps in unavailability.
    This is the step that I need most help with, as I am sure there is a faster way to do it..

    Step 3 - Locations + Schedule sheet

    After finding out which team members are most compatible, I'd pair them and assign them to a location. Further, I would sort them based on Attachment 396210location, so that the pairs of two are next to one another.

    Then, the pairs should, ideally, have no overlap in unavailability, thus making the shifts assignation very easy. I will show this with rows 17 and 18. I have marked in red the shifts that are not covered, as the cross check was at random and they would definitely be a bad match.
    But it's a good example, as it illustrates exactly what I am trying to avoid here.


    Any chance this can be done easier, please?
    I am to schedule a team of 80 volunteers, and this way is extremely time consuming.

    Many many thanks in advance!!!

    Is it possible to see the workbook? You might get quicker feedback.

    Re: Data Cross Checking from imported online poll

    Who would you give priority.. if there are 80 volunteers, then matching person A with B might cause person C to have no good matches for him.
    So optimal matches is very, very difficult to calculate (if not impossible).

    Hopefully I'm wrong and I'll learn something new soon


    -- edit (you can use this to calculate the number of times both have not said OK
    =SUMPRODUCT(($B7:$AE7="")*(INDEX($B$6:$AE$21,COLUMN(A1),0)=""))

    Oh I'm sorry. It was in the first paragraph. My bad vision glossed over it. My apologies!

    Well...this is a tough one because what you're really doing is a puzzle. Are you currently visually checking the best pairings? So here's one quick thing I came up with that would still require leg work but may eliminate at least a little bit of wasted time:
    1) convert "ok" to "1" using replace all feature
    2) do a subtotal at the bottom
    3) apply a filter
    4) in cell B2 or somewhere near the top/left, put this formula: SUMIF(B22:AE22,"1",B22:AE22)+SUMIF(B22:AE22,"0",B22:AE22)
    5) filter pairs

    Here is what I did: PairingsExample.xls

    You'll still have to click through each pairing....but you won't have to scroll left/right. For example, it took me about a minute to find Edith Sipos as the best pairing with Adela Muresan (only 6 time slots that they aren't paired together).

    However, that doesn't mean there isn't a better pairing for Edith.

    It's quite a big puzzle you have. I will continue to think about it. I hope the name list isn't too much longer than this or my possible time saver won't help much. Good luck

    Re: Data Cross Checking from imported online poll

    I wanted to look into this problem a little more.

    Pairing creates lots and lots of possible outcomes as I had mentioned above.
    I found here: https://www.physicsforums.com/thread...bjects.668904/ a nice formula to calculate the number of possible outcomes.

    If there are n people: (n!)/((n/2)!*2^(n/2))
    with n = 2: (2)/((1)!*2^1) = 2/2 = 1
    with n = 4: (4)!/((2)!*2^2) = 24/8 = 3
    with n = 6: (6)!/((3)!*2^3) = 720/48 = 15
    with n = 80 (80)!/((40)!*2^40) = (prepare yourself) = 79777941814291600000000000000000000000000000000000000000000 possible pairs. Good luck finding the best one
