Case Problem: Scheduling a Golf League
Note to Instructor: This case problem illustrates the value of the rational management science approach.
The problem is easy to understand and, at first glance, appears simple. But, most students will have trouble
finding a solution. The solution procedure suggested involves decomposing a larger problem into a series
of smaller problems that are easier to solve. The case provides students with a good first look at the kinds
of problems where management science is applied in practice. The problem is a real one that one of the
authors was asked by the Head Professional at Royal Oak Country Club for help with.
Solution: Scheduling problems such as this occur frequently, and are often difficult to solve. The typical
approach is to use trial and error. An alternative approach involves breaking the larger problem into a
series of smaller problems. We show how this can be done here using what we call the Red, White, and
Blue algorithm.
Suppose we break the 18 couples up into 3 divisions, referred to as the Red, White, and Blue divisions.
The six couples in the Red division can then be identified as R1, R2, R3, R4, R5, R6; the six couples in the
White division can be identified as W1, W2,\u2026, W6; and the six couples in the Blue division can be
identified as B1, B2,\u2026, B6. We begin by developing a schedule for the first 5 weeks of the season so that
each couple plays every other couple in its own division. This can be done fairly easily by trial and error.
Shown below is the first 5-week schedule for the Red division.
Week 1 Week 2 Week 3 Week 4 Week 5
R1 vs. R2 R1 vs. R3 R1 vs. R4 R1 vs. R5 R1 vs. R6
R3 vs. R4 R2 vs. R5 R2 vs. R6 R2 vs. R4 R2 vs. R3
R5 vs. R6 R4 vs. R6 R3 vs. R5 R3 vs. R6 R4 vs. R5
Similar 5-week schedules can be developed for the White and Blue divisions by replacing the R in the
above table with a W or a B.
To develop the schedule for the next 3 weeks, we create 3 new six-couple divisions by pairing 3 of the
teams in each division with 3 of the teams in another division; for example, (R1, R2, R3, W1, W2, W3),
(B1, B2, B3, R4, R5, R6), and (W4, W5, W6, B4, B5, B6). Within each of these new divisions, matches
can be scheduled for 3 weeks without any couples playing a couple they have played before. For instance,
a 3-week schedule for the first of these divisions is shown below:
Week 6 Week 7 Week 8
R1 vs. W1 R1 vs. W2 R1 vs. W3
R2 vs. W2 R2 vs. W3 R2 vs. W1
R3 vs. W3 R3 vs. W1 R3 vs. W2
A similar 3-week schedule can be easily set up for the other two new divisions. This will provide us with a
schedule for the first 8 weeks of the season.
For the final 9 weeks, we continue to create new divisions by pairing 3 teams from the original Red, White
and Blue divisions with 3 teams from the other divisions that they have not yet been paired with. Then a 3-
week schedule is developed as above. Shown below is a set of divisions for the next 9 weeks<\/p>\n","protected":false},"excerpt":{"rendered":"
