Create Proposed Schedule
Explanation
To generate proposed schedules for all the parts or individual parts on a
production line, based on the retrieved line demands, click Supply,
then Generate Proposed Line Schedule. Proposed schedules
represent a trial run at creating a schedule. The temporary output can be
overwritten with another attempt, or converted to a real production
schedule, or shop order requisitions if acceptable as the new schedule.
After generation, you can review the proposed schedule relative to the
demands and current schedules.
Several different options can be offered for schedule generation,
considering different inputs and scheduling approaches. The production line
calendar is used to govern all the available production days. You can
generate a proposed schedule by indicating:
- The Production Line or Production Line Part for
which a schedule should be generated.
- The demand date range to use for the quantity inputs.
- The scheduling approach. The available options are:
- Load Infinite schedule by meeting demands with equal
supply, regardless of line rate: Loads demands directly to
the schedule date without any modification
- Backward schedule taking into account existing schedules
and the line rates per date: Demands are allocated to the
line, using the line rate to determine the allocated proportions of
each part. Quantities that cannot be produced within a single day
roll to the previous day. Any unallocated demand quantities at the
firm horizon are stacked at the firm horizon limit.
- Forward schedule taking into account existing schedules
and the line rates per date: Demands are allocated to the
line, using the line rate to determine the allocated proportions of
each part. Quantities that cannot be produced within a single day
roll to the next day. If necessary, schedule quantities can be
promised beyond the scheduling horizon, as firm schedules that will
meet the demands.
Prerequisites
Production line demands must exist.
System Effects
- Proposed line schedules will be generated for the production line.
- Existing proposed schedules for the affected date range and parts
will be deleted and replaced with the new schedule. The proposed
schedule is a temporary working place to create simulated schedules for
a production line. Only one proposed schedule can exist at a time for a
given production line (i.e. two different planners cannot simultaneously
work on their own versions of a proposed line schedule).
- If the option Remove Past Due Propose Schedules is
enabled, proposed schedules with a schedule date earlier than current
date will be removed.
