| | To use the planned date determiner optionsThe loading and unloading
dates and times calculated for shipments are based on the planned load/unload
dates and the loading and unloading time windows of the freight
orders on which the load plan is based. The planned dates and the time windows
of the freight orders, in turn, are created manually or are derived from the
planned dates of the originating orders. When load building is
carried out, stops are created from the
addresses of the freight orders on which the load plan is based. If the time windows of
the freight order are large, which signifies a surplus of time between the
earliest and the latest load or unload date, the planned dates calculated for
the shipments can differ considerably from the planned dates of the originating
orders. To prevent the load building engine from calculating
undesirable planned shipment dates, the following planned date determining
options are available to control the way planned loading and unloading dates
are calculated for shipments. You can access these options in the Generate Plan (fmlbd0280m000) session: Earliest of Possible Dates The planned dates of
the shipment are equal to the earliest possible loading and unloading dates
defined in the stop. Use this option if you want the shipment to be delivered
or received as soon as possible. Latest of Possible Dates The planned dates of
the shipment are equal to the latest possible loading and unloading dates
defined in the stop. Use this option if you want to postpone delivery or
receipt of the shipment as long as possible, for example, to enable the use of
transport capacity for rush orders. Minimum of Planned Unload Dates The calculation of
the planned dates of the shipment is based on the earliest planned unload dates
of the original orders. Load dates are calculated by subtracting the travelling
times from the unload dates. If you use this option, all shipments are
delivered or received on or before the planned unload date of the originating
orders. If, however, large load date tolerances are used, the shipments might
not be delivered or received at the earliest possible date. Average of Planned Unload Dates The calculation of
the planned dates of the shipment is based on the average date of the planned
unload dates of the original orders. All order lines are equally taken into
account at all stops to determine the average date. As a result, some of the
shipments are delivered somewhat later than the planned unload dates of the
originating orders.
Note - If the Minimum of Planned Unload Dates or the Average of Planned Unload Dates are outside the time windows of the freight
orders, the nearest time window border is taken as the minimum or average date.
The planned dates for shipments must be within the time windows. The following
example shows a situation in which a Minimum of Planned Unload Dates is outside the time windows of one of the freight
orders in a shipment.
- If a load plan is replanned or when new order lines are added
to a load plan, the same planned date determining option is used as the one
used for the original plan. When planning is initiated from an external source,
such as the graphical plan board, you can use the Average of Planned Unload Dates option to calculate the planned shipment dates.
Example Shipment A includes
freight orders 1 and 2. The unloading time window for freight order 1 is
October 4, 2005, 09:00 - 12:00 and the planned unload date is October 4, 2005,
10:00. For freight order 2, the unloading time window is October 4, 2005, 11:00
- 13:00 and the planned unload date is October 4, 2005, 12:30. The planned
unloading date/time 10:00 is outside time window of freight order 2. Therefore,
the nearest time window border, which is 11:00, is taken as the minimum planned
unload date. | |
