IBM ILOG Scheduler User's Manual > Getting Started with Scheduler > Adding Transition Times > Describe the Problem--Example 5

In this example, we have one worker who is required to build three houses. The tasks in each house have different durations corresponding to the house design (Duration Design 1, 2, or 3 in Table 5.1). There is also a transition time between tasks that is based on the activity transition type. In this example, every activity has its own transition type. The actual transition times are defined later.

In addition, the second house cannot be started before day 5 and must be finished by day 80.

As in all our previous examples, our objective is to minimize the makespan of the problem.
