STBS interface generates automatically the graphical output for the problems. Figure 1 illustrates the optimal assignments for the example problem with 5 orders in 650 hours of operation.

The arrows represent the due dates for each order and the bars show the duration of each processing stage. The number above the bars indicate the unit in which the task is processed and the number below it indicates its duration. Note that all the orders are produced within the dates required.

In Figure 2, the optimal assignments are shown for the first production stage, which is composed of units 1, 2, 3, 4 and 5. The legend above each bar corresponds to the order processed and the one below it is related to the duration of the task.
