Production scheduling and simulation views
A scheduling view places work orders on resources and time. A simulation view lets a planner test a change before it reaches the floor.
Planners use both together, since most scheduling decisions start as a question about the effect of a change.
Key facts
- A schedule is read in four layers: capacity, sequence, material and due date.
- A change to a live schedule reaches operator screens at once.
- A list of differences is easier to act on than two full charts side by side.
- Drag and drop without constraint feedback lets a job land where material is not yet available.
- Automatic rescheduling finds better sequences and is harder to trust when nobody can explain why a job moved.
What it covers
| Layer | Question it answers |
|---|---|
| Capacity | Is this resource overloaded in this window? |
| Sequence | What has to finish before this can start? |
| Material | Will the inputs be there when the job starts? |
| Due date | Which orders will be late if nothing changes? |
Scheduling screens take several forms: a board of jobs by machine or work centre, a kanban by run state, a timeline against a now marker, and a large-screen view for the floor.
Who uses it
| Role | What they do with the schedule |
|---|---|
| Planner | Places and moves jobs, tests changes before committing |
| Supervisor | Follows the shift against the plan and reacts to deviations |
| Operator | Sees what runs next at the station |
| Sales or customer service | Checks when an order will be ready |
What makes it hard to design
Simulation before commit. A what-if copy lets the planner move jobs, add a shift or remove a machine, review the effect as a list of differences such as orders that become late or capacity that frees up, and then commit or discard.
Constraint feedback. Drag and drop needs to show, at the moment of the move, when material, capacity or sequence make a placement impossible.
Several time scales. The same schedule is read by the hour on the floor and by the week or month in planning. Zoom levels and a visible now marker keep both readers oriented.
A schedule mixes plan and reality. Jobs that are running, late or blocked need to look different from jobs that are only planned.
Trade-offs
- Automatic rescheduling finds better sequences than manual placement. Operators and supervisors find it hard to trust a plan when nobody can explain why a job moved.
- A simulation copy protects the floor from half-finished changes and adds a step for small, obvious moves.
Common mistakes
- Drag and drop without constraint feedback. A job is placed where material is not yet available, the chart looks fine, and the conflict surfaces on the floor.
- Comparing two full charts to see what a change did
- Look-alike job cards with placeholder text that hide production status
- No difference between planned and running work
