12 Man doubles Tennis schedule

[jw1044]

I am trying to schedule a senior Tennis league that consists of 12 players, 6 teams of doubles, playing three times a week, year round.  The goal is for each person to play with and against each of the other players approximately the same number of times throughout the year.  How would I go about scheduling this so that the schedule would be random.  The doubles partners would also be random.

Any help and advice would be appreciated.

If you follow the schedules link above, and choose 12 players and 'Whist' then you will get a doubles schedule for 11 rounds.  This will give you each pair with each other once and against each other twice.   So for the whole year you need to use multiple copies of this basic schedule, but for each copy make a different random assignment of you 12 players to the player numbers 1 to 12.
