Using Time Modes on Operations

You can use various time modes on operations: estimated, measured, simulated, and analyzed times.

In the task below, only estimated and analyzed times are shown, and measured and simulated times work in a similar way.

About Time Modes on Operations
  1. Open a system structure with operations similar to the one below in your app.


  2. Defined time modes and estimated time values in the Properties dialog boxes of the operations as follows:
    • Right-click Operation 1 and specify the Time Mode as Estimated Time and the Estimated time to 10.
    • Right-click Operation 2 and specify the Time Mode as Analyzed Time and the Estimated time to 7.
    • Right-click Operation 3 and specify the Time Mode as Analyzed Time and the Estimated time to 25.
  3. In the Gantt chart, create precedence time constraints between the Operations 1 and 2.
  4. Using the Time-Motion Study app, create a time analysis for Operation 2:
    1. Enter a name and the required subsystem and click Finish.
    2. In the STM interface that opens, define, and save the time analysis.
    See the Time-Motion Study User's Guide for more information.
  5. In the same way, create a time analysis for Operation 3.
  6. Click Process Gantt to display the Gantt chart.


    The times in the Duration column are the times that were specified on the operations, which may be estimated or analyzed times.
