Understanding the calculated duration time

Duration of an element is the overall time it takes to execute its direct children. If all the children are parallel (no flows between them), it is the length of the longest child. In the case where there are flows between the children, it is the overall time it takes to execute the children according to the order (flows) between them. Calculated duration of upper levels is based on the calculated duration of lower levels. If the lower level has no children (for example, a process that has no processes or operations below), its calculated duration is equal to its duration.

• For a process with only child operations, the calculated duration is the length of the longest path of operations. If the operations have flows between them, it is the overall time it takes to execute them according to the flows.

• For a process with child processes, Teamcenter first calculates the calculated duration of each child process containing only child operations, and then calculates the longest process duration of the processes based on the calculated duration time of the subprocesses and operations.

If there are, for example, four operations with the same parent, having duration times of one second, two seconds, three seconds, and four seconds, the calculated time for the parent process is four seconds. If, however, the second operation must be completed before the third, the calculated duration time is 5 seconds for the parent process.

Use the Show calc duration button to show or hide the calculated duration time. Teamcenter shows a bar across the top of each time element displaying the calculated duration path of the children of this time element.
