Sequence-dependent allergen washdowns between peanut butter and plain dough lines caused catastrophic 4-hour caustic flushes. Production schedulers relied on 14 separate spreadsheets that frequently desynchronized tunnel ovens from packing cells, resulting in hot dough backups and emergency dump dumps.
Implemented bidirectional SAP S/4HANA RFC integration. Formulated an N×N asymmetric traveling salesperson matrix with AddCircuit() to group allergen SKUs without starving downstream shelf life. Changeovers were bound to strict disjunctive mechanics constraints (2 shared crew members across 14 lines).
Total CIP washdown time plummeted from 435 mins/week to 65 mins/week. Zero oven starvation stops recorded across 12 consecutive months. Unscheduled weekend overtime shifts collapsed from 18 shifts per month to just 2, saving over $340k in premium labor.
“Prior to Cadence, our master scheduler spent six hours every morning fixing schedule collisions when dough mix batches were delayed by 15 minutes. Cadence solved the entire week’s finite capacity in 45 seconds, perfectly pacing our tunnel ovens and saving us almost 30 hours of caustic washdown every week.”

The Plant Leader Audit Protocol & Verification Methodology
Cadence does not measure ROI with vanity projections. Every payback metric is confirmed through an air-gapped three-stage mathematical reconciliation protocol before being published.
Pre-Cadence Baseline Logging
We extract 90 days of raw unedited historical ERP work orders, actual machine SCADA runtimes, maintenance logs, and shift scrap reports. This establishes the uncontested physical baseline of shop-floor performance.
• True changeover duration audit
Air-Gapped Counter-Factual Replay
The historical order book is fed through the Cadence CP-SAT constraint engine with identical machine capacities and real-world downtime events. This mathematical simulation proves exact delta potential without confounding variables.
• Strict resource conflict verification
Post-Go-Live 90-Day Financial Re-Audit
Following pilot launch, plant financial controllers and plant engineers audit shift logs, scrap slips, and utility costs against solver promises. The payback period is signed off exclusively when realized savings meet or exceed the target.
• Continuous variance drift telemetry
