Generating special schedules

IPP&E can generate three special schedules: the best-case schedule, the worst-case schedule, and the most-likely schedule. You can compare the original schedule with any of these schedules and then do a what if analysis to provide an assessment of the original schedule for the bid.

Note: This capability is only available with the Aurora integration, which is available in Support Center.

Ideally, the original schedule for the WBS structure must be created before generating these special schedules. Therefore, as a pre-condition for using these schedules:

• Data for the WBS structure must be exported to the external schedule.
• All the constraints and span time must be updated in the external schedule.
• Schedule dates must be generated in the external schedule.
• Data must be exported back to Teamcenter from the external schedule.

The special schedule can be generated by exporting the data to the external schedule using the appropriate workflow. The system collects information based on the type of schedule to generate. Once the export is complete, you can generate the schedule in the external schedule.

Best-Case Schedule

The best-case schedule assumes that all the opportunities associated with different elements of the WBS structure are realized, allowing you to visualize the schedule as if all the opportunities are incorporated. You can compare the original schedule with the best-case schedule to perform the what if analysis.

The best-case schedule can be generated by submitting the WBS root to the IPPE TC To External Schedule Transfer Best Case workflow. When data for the best-case schedule is exported to the external schedule, the sum of the time span of all the opportunities applicable to the work package is subtracted from the span time of the work package. The resultant time span becomes the task duration in the external schedule. Effectively, opportunities reduce the duration of the task and schedule.

Worst-Case Schedule

The worst-case schedule assumes that all the risks associated with different elements of the WBS structure are realized, allowing you to visualize the schedule as if all the risks are incorporated. You can compare the original schedule with the worst case schedule to perform the what if analysis.

You generate the worst-case schedule by submitting the WBS root to the IPPE TC To External Schedule Transfer Worst Case workflow. When data for the worst-case schedule is exported to the external schedule, the sum of time span of all the risks applicable to the work package is added to the span time of the work package. The resultant time span becomes the task duration in the external schedule. Effectively, risks increase the duration of the task and schedule.

Most-Likely Schedule

The most-likely schedule assumes that all the risks and opportunities associated with different elements of the WBS structure are realized, allowing you to visualize the schedule as if all the risks and opportunities are incorporated. You can compare the original schedule with most-likely schedule to perform analysis.

You generate the most-likely schedule by submitting the WBS root to the IPPE TC To External Schedule Transfer Most Likely Case workflow. When data for most-likely schedule is exported to the external schedule, the sum of the time span with its probability of all the risks applicable to the work package is added to the span time of the work package. Also, the sum of the time span with its probability of all the opportunities applicable to the work package is subtracted from the span time of the work package. The resultant time span becomes the task duration in the external schedule.
