| Line Segment - Line Sequence (tiasl4500m000)Use this session to display the planning
data for a line segment. You can see the sequence of assembly orders, planned and
actual, and display the following attributes for an assembly order: - Whether another order
has requested the start of this order, which is defined in the Process Trigger Definition (tiasl8100m000) session.
- Whether the order has
been offset.
- Whether the order
position can be altered, which you can change here.
- Whether the
line-station order has the status Frozen.
By means of the Show Orders command on the appropriate menu, you can
choose which orders you want to see. - All orders.
- Start requested.
- Started.
- Completed.
Sequence Type The Simulate and Create Line Sequences (tiasl4200m000) session generates the following sequences: - The Actual sequence, which cannot be modified in the Remix Line Mix (tiasl3220m000) session.
- The Generated sequence,
which you can modify in the Remix Line Mix (tiasl3220m000) session.
Line Segment Each line segment has an
individual sequence of orders. Next Line Segment A set of consecutive assembly-line work centers on an assembly
line between two buffers. The first buffer is the beginning of the segment, the
next buffer is the first part of the next segment. For more information, refer to Position Identifier for the assembly order in this segment. The position
order is the sequence that the order is processed in. Assembly Order An order to assemble a product on one or more assembly lines. SequenceStatus Line sequences shown here can have one of the following
statuses: Planned Start Time The time when work starts on the assembly order in the current
segment, according to the initial plan that was generated during sequencing. Planned End Time The time when work finishes on the assembly order in the
current segment, according to the initial plan that was generated during
sequencing. This time must be later than the Planned Start Time. StartRequested This parameter is an information display field. If this check box is selected, you know that the assembly order can be started on the line segment in
question. In other words, the assembly order is released for assembly on the
line segment. You can select this check box in the Request Start - Assembly Order on Line Station (tiasc4200m000) session. You can start
the Request Start - Assembly Order on Line Station (tiasc4200m000) session: - From the appropriate menu in the Line Station - Assembly Orders (tiasl6510m000) session.
- By using
process-triggered workflow.
You define the
triggers in the Process Trigger Definition (tiasl8100m000) session. In the Process Trigger Definition (tiasl8100m000) session, define the Request Start - Assembly Order on Line Station (tiasc4200m000) session as a session
that must be triggered by a process trigger that is defined in the Process Trigger Definition (tiasl8100m000) session. You can request an assembly order
to be started on a line segment on the supplying line, based on a completion
date, or based on a start date of the same order on the main line. Offsetting Required If this check box is selected, this order has not yet
been offset or the offset data
are no longer up to date. The line station orders for this assembly order must
be offset. Item The end item of the assembly order. Actual Start Time This field denotes the time when work in the selected segment
actually starts on the assembly order. Actual End Time The time when work in the selected segment is actually finished
for the assembly order. Fixed If this check box is selected, the planned delivery
date of an assembly order is fixed. This check box is
selected in the following situation: When the assembly orders on the main line
are sequenced, the sequence of the segment that is connected to a supplying
line is copied to the last segment of the supplying line. Because the sequence
of the last segment must be the same, if no buffer exists between the last
segment of the supplying line and the main line, the assembly orders are fixed
on the last segment of the supplying line. If you sequence the
supplying line separately, such as to make a spare order that does not flow
into the main line, the positions of the fixed orders remain the
same. Frozen If this check box is selected, the line-station order
(LSO) status is Frozen. LSOs are frozen
during the Generate Assembly Orders process in Line Assembly Control (LAC). A
line segment, as well as the LSOs that belong to the segment, is frozen when
the line segment falls in the freeze time fence, which is defined for every
line segment. To fall in the freeze time fence, the LSO offline date minus the
current date must be less than the freeze time fence. When assembly orders
are generated, LN checks
whether these orders must be frozen or partially frozen. This also affects
the usage of the Quantity to Allocate parameter. Firm If this check box is selected, the assembly date of the
order is fixed in the line sequencing. Note - Once the assembly order is firmed, line sequencing will not
be allowed to reschedule the assembly order in the last line segment of the roll-off line
- You can select this option or clear when the status of
assembly order is Sequenced or In Progress.
