The Scheduler Node determines which designs need to be evaluated. The strategy used to select the DOE designs of interest, and to generate new designs, is determined by the scheduling algorithm selected. This node always follows the DOE node, and it cannot be disconnected from it.
The configuration panel for the Scheduler node is composed of two separate sections.
The panel on the left side (Schedulers) allows you to select the
scheduling algorithm that you wish to use to determine the sequence of designs to be evaluated.
The panel on the right side is then used to provide the required parameters for the algorithm
currently selected. Once you are satisfied with your selection, you need to press the
button (located at the bottom of the dialog). If at any point
you are not satisfied with the parameters you have selected for an algorithm, you can reset
the default values by clicking the
button (located at
the top of the Schedulers panel).
Detailed information about the various scheduling algorithms available is provided elsewhere (see Chapter 7, Design Schedulers).
This node input is always connected to the DOE node output.
The Scheduler node output connector can be connected to one, and only one, process input connector. belonging to one of the following node types:
Several error messages can be associated with the scheduler node:
| 150 | MISSING SCHEDULER NODE | There is no DOE/scheduler pair in the Work Flow |
| 151 | SCHEDULER NOT DEFINED | A scheduling algorithm has not been selected |
| 152 | SCHEDULER NODE IS NOT CONNECTED | The scheduler's output is not connected to any node |
| 153 | ONLY ONE OBJECTIVE IS ALLOWED FOR THE SELECTED SCHEDULER | A single-objective scheduling algorithm has been selected, but more than one objective has been defined in the Work Flow |
| 154 | OBJECTIVES ARE NOT DEFINED FOR THE SELECTED SCHEDULER | An optimization algorithm has been selected as the desired scheduler, but no objectives have been defined in the Work Flow |
| 155 | INPUT VARIABLES ARE NOT DEFINED FOR THE SELECTED SCHEDULER | Any scheduling algorithmn requires at least one input variable, but none has been defined in the Work Flow |
