there is a medium price discount. If the seats remaining are greater than 50 percent and the number of
days before travel are greater than 21, there is only a small discount.
If the seats remaining are from 20 to 50 percent and the days before the flight are fewer than 7,
the ticket has a medium discount. If the seats remaining are from 20 to 50 percent and the flight date
is from 7 to 21 days in the future, there is a low discount for prices. If the seats remaining are from
20 to 50 percent and the number of days before travel are greater than 21, there is no discount.
If the seats remaining are less than 20 percent and the number of days before the flight is less than 7,
the ticket has the highest increase in price. If the seats remaining are less than 20 percent and the flight
date is from 7 to 21 days in the future, there is a large increase in price. If the seats remaining are less
than 20 percent and number of days before travel are greater than 21, there is a small increase in price.
Develop an optimized decision table for the Cloudliner Airlines ticket price adjustment policies.

Group Projects

1. Each group member (or each subgroup) should choose to become an “expert” and prepare to explain
how and when to use one of the following structured decision techniques: structured English, deci-
sion tables, or decision trees. Each group member or subgroup should then make a case for the use-
fulness of its assigned decision analysis technique for studying the types of structured decisions made
by Maverick Transport on dispatching particular trucks to particular destinations. Each group should
make a presentation of its preferred technique.
2. After hearing each presentation, the group should reach a consensus on which technique is most
appropriate for analyzing the dispatching decisions of Maverick Transport and why that technique is
best in this instance.
