    Optimal Mentor-Mentee Pairings Problem

    Hi Guys,

    I work for a mentoring nonprofit in the UK. For every programme that we run in a school, we pair up mentors and mentees based on 3 criteria: the strength / engagement of the individual, their preferences, and the skill they most want to develop.

    Is there any way for Excel to draw up a list of optimal pairings for a group of 15 mentors and 15 mentees?

    Here’s an example data set

    Points of Note:
    – A Year ‘7’ has to be paired with a Year ’10’.
    – The heirachy of criteria is: Strength, Preferences, then Skill.
    – We want to pair up ‘Strengths’ in a heirachy too. (i.e. We would want to pair up an ‘A’ with another ‘A’, but failing that we would want to pair them with a ‘B’ before pairing them with a ‘C’.
    – Each individual gives 3 preferences. However, these preferences aren’t ranked. We value their third choice as much as their first.
    – I’m aware that there might be a programming / macro solution. However, we as a team we use Macs which makes this difficult(?)

    Really grateful for any help or pointers.

    You could try creating a matrix with your year 10 students along the horizontal axis and year 7 on the vertical axis.

    Each combination would be given a score which would would be based upon the sum of the individual scores for your criteria with a weighting of your choice. e.g. use lookup functions to get the strengths and give a high score to where they are identical, a lower score to where they differ by one level etc.

    A formula could then determine the maximum score in each row and column. The first set of pairings would be those where the maximum scores for row and column coincide.

    The exercise could then be repeated with the parings assigned above removed from the analysis.

    Hi Martin,

    That's excellent - and has set me off on working with this right away. I have the capabilities to do the basic scoring (e.g. return a score if there is a match), but I don't know how I can use lookup to return a score if something is close. How might I do that?

    Best Wishes,

    Olly

    If you look up the values A,B,C for the student using the VLOOKUP function, you can further convert these to ASCII codes (using the ASC function) to give the numbers 65, 66 and 67 respectively. Then you can subtract these and use the absolute value (ABS function) to give you a measure of closeness.

    Hello, just saw your post. Would you be willing to share your excel file that you landed on? Looking for similar.

    Well I just found the forum today. No need for the snarky reply. The original file doesn't show what formulas were used. Just trying to learn something new here on my own. Thanks for the unnecessary response.

    Create a new thread and I'm sure you will have lots of replies.

    I (for one) will have a look.

    The response was not unnecessary. If you had bothered to look, you would indeed see the file in post #1 is the only file on this thread. There were suggestions on how to improve that file, but no other file/s where uploaded
    1. Use code tags for VBA. [code] Your Code [/code] (or use the # button)
    2. If your question is resolved, mark it SOLVED using the thread tools
    3. Click on the star if you think someone helped you

    Re: Optimal Mentor-Mentee Pairings Problem

    I think that nagelgal was asking ollyo2 to share the final workbook with his matching matrix, based on what was said in post #5. Unfortunately, olly02 has not been here since that day in 2018 when he last posted, so the workbook won't be forthcoming. Opening a new thread would be the best course of action here.
