PERL 105 Practicum:
Scheduling Session
Factors to Consider





Availability of space
Facility (size and suitability)
Sport (length of games)
Participant conflicts
Nature of competition (recreational or
competitive)
Selecting a Format
Basic formats
1.
Round Robin
2.
Elimination
3.
Combination
The main difference between the two formats is the number
of guaranteed games that teams will play. Therefore, it is
important to decide on the nature of the tournament and
whether you want to emphasize participation or competition.
Round Robin
Ideally, all teams play each other at least once.
•
•
•
•
•
Ensures all teams play the same number of
games
For large leagues, pools are often used
Need more time for this format
Better for teams with less skill just looking to
have fun
Ex. NBA Regular Season
Round Robin Scheduling

*Even # of Teams
– Round 1



A vs B
C vs D
E vs F
– Round 2



A vs D
B vs F
C vs E
– Round 3




A vs F
D vs E
B vs C
Etc…

*uneven # of Teams
(ie. there will be a bye)
– Round 1



F vs A
B vs C
D vs E
– Round 2



F vs C
A vs E
B vs D
– Round 3




F vs E
C vs D
A vs B
Etc…
Round Robin – Determining a
winner

Often attach points to wins, ties, and loses.
Team with the most points wins.
– Ensure a small point differential


You can just do # of wins
Ties – you need a process to decide on ties
at the end of your schedule
– Consider head-to-head results, fairplay points,
points for and against, etc…
Elimination
Teams are eliminated from the competition after
one or more losses
• Emphasizes winning
• Doesn’t take as much time
• Better for teams with a high level of skill
looking for a competitive format
• Games cannot end in a tie
• Ex. NHL Play-offs
Byes
Byes occur when there are an odd number of teams
• More difficult when scheduling elimination
tournaments
• Get rid of all byes in the first round
• Number of participants (real or implied) needs to be
a perfect power of 2 (2, 4, 8, 16)
Equal Total: Rank of teams is ______.
Formula: ___________ (where N=number of teams)
Equal Difference: Rank of teams is
_________ or all rankings are similar
Formula: ___________ (where N=number of teams)
Combination
Use a combination of both Round Robin and
Elimination in the same schedule
• Preliminary rounds are often Round
Robin (often include pools) and playoffs
are Elimination
• Ex. MacEwan Rec leagues and
tournaments
Double Elimination
Tournament



Quicker tournament with more games
per team
Each team must lose twice before they
are out
Made up of a winners bracket and a losers
bracket
– Winner of Losers Bracket can still win the
tournament.
Scheduling Assignment
Volleyball Tournament (Recreational)
– 8 teams
– 2 courts
– 1 hour games
– 8 hours total (9 am – 5 pm)
– A tournament champion must be declared
at the end of the tournament
Build a schedule using any format you like. Be
prepared to explain your choices.
