If things flow through your system at a rate, and interruptions disrupt that flow — discrete rate is the right paradigm.
Bottling & Packaging
High-speed filling, capping, and labeling lines where a 3-second micro-stop cascades through four downstream stations.
Pharma & Life Sciences
Regulated, tightly coupled processes where every interruption must be modeled precisely for compliance and capacity planning.
Hospital Patient Flow
ED arrivals, bed turnover, discharge rates, shift changes. The constraint shifts by hour — simulation reveals which interventions matter when.
Chemical & Continuous Process
Reactors, distillation columns, heat exchangers. Progressive rate degradation from fouling is an interrupt — not just on/off failures.
Water & Wastewater
Treatment stages with scheduled backwash cycles, seasonal demand variation, and parallel unit constraint shifts.
Power Generation
Combined cycle plants with rated outputs, forced outages, and partial derating — the system doesn't stop, but the constraint tightens.
Food & Dairy Processing
Continuous flow with CIP cycles, quality windows, and cold chain constraints. Buffer sizing isn't just throughput — it's product integrity.
Semiconductor & Electronics
Batch and flow processes with ultra-low cycle times and yield events that ripple through entire fab lines.
Oil & Gas Pipelines
Compressor stations, metering points, line pack as buffer. When a compressor trips, the pipeline is a constraint system.
Specialty Materials
Small-batch production with tight quality windows, long changeovers, and cure times. Rate shifts with composition; yield events behave like scheduled interrupts.
Fleets
Trucks, rail, or mobile equipment as a system. Vehicle availability is the constraint; maintenance cycles, refueling, and driver hours behave exactly like interrupts on a line.
