Better scheduling isn't a tidier spreadsheet; it's a set of disciplines. Schedule the bottleneck first, sequence to kill changeovers, build realistic buffers, and feed the plan with real data. Here are eight practices that move on-time delivery more than any amount of extra effort.
- Schedule the constraint, not the whole plant. Throughput is set by the bottleneck. Sequence it first and let the rest of the line follow its drumbeat.
- Group sequence-dependent changeovers. Order jobs so similar setups run back-to-back (by colour, format, or tooling) to slash total changeover time.
- Schedule to finite capacity. Never load a resource past the hours it actually has free. An overloaded plan is just a hidden late delivery.
- Use real run rates, not nameplate speeds. Pull actual rates from OEE so the plan reflects how fast the line genuinely runs.
- Protect maintenance windows. Pull planned PM from the CMMS into the schedule so you never plan production on a machine about to be taken down.
- Build realistic buffers. Add time buffers before the bottleneck and the shipping date to absorb normal variability without a cascade.
- Use a frozen horizon. Lock the next shift or two so the floor isn't whipsawed by every change, while keeping the rest of the schedule flexible.
- Reschedule on events, not on a calendar. Rebuild when a machine drops, a shipment slips or a rush order lands - not just once a week.
Keep a human in the loop
The best setups treat the scheduler as decision support: it surfaces risks, flags emerging constraints and runs what-if scenarios fast, while a planner stays accountable for the plan that actually runs. Tools inform the decision; people own it.
Put these into practice on one line. Book a Fabrico demo or model the gains with the OEE Calculator.
FAQ
What is the single most important scheduling practice?
Schedule the bottleneck first - it sets the throughput of the whole line, so protecting it protects your due dates.
How often should I reschedule?
On meaningful events such as a breakdown, a late delivery or a rush order, not on a fixed weekly cadence - which is why fast, automated rescheduling matters.
