Buffer-in Time

This field applies to APS.

Enter the number of hours to delay the start of the operation (this value is added to the Move hours specified on the operation). A job cannot begin processing any operation requiring this resource group until after this buffer time + the move hours value has elapsed. Delay of the job begins when it completes the previous operation. The delayed job does not utilize resources in this resource group or the resources used at the previous operation.

To determine the total buffer time between two operations, the system:

  • Finds the largest Buffer Out value from all of the first operation's specified resource groups (if it specifies more than one).
  • Finds the largest Buffer In value from all of the second operation's specified resource groups.
  • Adds the two values to the sum of the first operation's Finish hours and the second operation's Move hours.
Note:  If the Infinite Resource Capacity After field is set to 0 on each of the operation's resource groups, the operation's Queue hours are also added to the total buffer time between the two operations.
