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.
