Calculation of the Dates
General
The results of scheduling include:
- earliest start-/ end dates , latest start-/ end dates and calculated start-/ end dates on project level
- earliest start-/ end dates , latest start-/ end dates and calculated start-/ end dates on task level
- and, if resources are already planned, calculated start/ end dates of the assigned resources as well as their loading and capacity adjustment.
Calculation of Start Dates
Information
- The network theory and the practical approach are available for determining the start of a task successor.
| Network plan theoretical approach | Practical approach The successor does not start before the next day.  |
- in PLANTA project
- tasks with duration > 0 and EA relation are planned according to the practical approach, i.e. The successor starts on the following working day
- tasks with duration = 0 (e.g. milestones) and EA relation are planned in the following way:
- If the duration of a task = 0, you can define via the Successor task start +1 day model parameter when its successor is supposed to start.
- If the successor of a task has a duration of = 0, the successor always starts on the same day as the task itself.
Details
- Requested and actual dates on non-working days (vacation, absence) remain valid and are taken into account during the calculation of the calculated dates. Start and end dates can thus also be scheduled on non-working days. However, the duration of a task is displayed in working days regardless. The resources are only loaded on working days.
Example
- The TA Requested start of task A falls on Sunday, 11/10/2019, a non-working day. The start of task A is scheduled for the Requested start date.
- Task B has no requested date, it therefore starts on the next working day.
- Resource Ronja Koch is on vacation from 11/11/2019 to 11/15/2019. It is not planned within the vacation period.
