Transportation time for linked assembly lines
A supply line linked to multiple parent lines, can be physically present in the
same geographical location as the parent lines or can be located in a different
geographical area. If the supply line is located in a different geographical
area, the time to transport assembled components to the parent line must be taken into account when planning the assembly orders.
Note
The transportation time for the supply of assembled components
between the supply line and parent lines must be defined for multisite assembly scenario as well as the single site
assembly scenario. The assembly lines must be logically linked in the assembly
line network structure.
Example
The following example shows a supply line which is linked to
two different parent assembly lines.
The tranportation time is calculated based on the
following:
To calculate the transportation time, you must link the last line station of the last line segment of the supply line to a line station on a parent assembly line.
In the above example, the last line station L2Z of the last line segment S2Z
can be linked to L3A on main line A and/or to L3B on main line B.
You must define the address for the linked line stations and use
the distance tables in Freight to calculate the transportation time.
Note
If multiple supply lines are linked to the same line station
on the parent assembly line, each supply line-parent line combination can have their
specific transportation time.
Important!
The transportation time is displayed only on the line station
order related to the last line station of the last line segment on a supply line.
The transportation time is taken into account for the following
processes:
Generating Assembly Orders: When assembly orders are generated, line station orders (LSO) are also generated. The Planned Transport End Date of the line station order related to the last line station of the supplying line, is
set to the start date of the assembly order. The Transport Time is set to zero.
Offsetting line station orders where the Assembly Order Status is Planned: Offsetting line station orders is based on the
transportation time and the defined line segment lead time offset . The Planned Transport End Date of the line station order
related to the last line station of the supplying line is set to the end date
of the line station order. The value of the Transport Time field is set to zero.
Offsetting line station orders where the Assembly Order Status is Sequenced: Offsetting the line station orders on the
supplying line is based on the transportation time in order to determine the
start time and end date of the line station orders on the supply line. The Planned Transport End Date of the last line station
order on the last line segment of the supply line is set to the Planned Start Time of the linked line station order
on the parent line. The Transport Time is calculated using the following
formula:
Planned End Time - Planned Transport End Date
While calculating the transport time, the values
from the last line station of the last line segment of the supply line are
considered.
Line sequencing: The transportation time is taken into
account during the Synchronizing Supplying Lines process for assembly orders
with the Sequenced status. The start time of the (LSO) of the line station on the parent line is offset with the transportation time
to determine the end date of the LSO of the last line segment of the supplying
line. In case of a multi-site assembly model, this end date on the last line
station order is equal to the offline date of the assembly order, on the
supplying line.
Determining segment schedules: The transportation time is taken into account when segment
schedules are calculated. The transportation time is used to offset line
segments when the dates at which the assembly parts are required, are
calculated.
