How is the line constraint model built and maintained?

The line constraint model is configured in HublerX by the planning team — the approved product list per line is loaded from the ERP product master and engineering records; line speeds per SKU are taken from production standards; the changeover matrix is built from historical changeover records and the process engineering team's input. The model is reviewed and updated when lines are modified, new products are approved, or changeover standards change.

Can the schedule optimisation handle minimum run quantities?

Yes. Minimum economic run quantities — configured by line and product to account for the cost of a changeover relative to the batch size — are enforced during schedule generation. WOs below the minimum run quantity are either combined with an adjacent run of the same product or flagged for the planner to review before the schedule is issued.

How does HublerX handle a WO that can only run on a line that is already at capacity?

Where a WO's only approved line is at capacity during the required window, HublerX surfaces the capacity conflict with the specific WO competing for the same line time, the impact on the delivery due date, and the options — prioritise this WO and defer another, add overtime to the line, or negotiate a revised delivery date. The planner resolves the conflict; HublerX updates the schedule.

Can the constraint model handle multi-stage production where a product goes through two lines?

Yes. Multi-stage production routes — where a product is, for example, baked on Line 1 and then packed on Line 3 — are configured as a sequence of operations in HublerX. The schedule coordinates both stages, ensuring the downstream line has capacity available when the upstream stage completes, with the configured inter-stage buffer time accounted for.

Production Scheduling with Line Constraints

HublerX builds production schedules that respect the actual constraints of each line — approved product list, line speed by SKU, changeover time between products, allergen sequencing rules, and minimum run quantities — producing a schedule that the shopfloor can actually execute.
