Operational Simulation · One production shift on an 8-stage assembly line

Same demand and same line on both sides — only the maintenance policy changes (reactive vs predictive)

REACTIVE MAINTENANCE
Fix-on-failure · MTBF 1.0× · MTTR 1.0× · Normal demand

PREDICTIVE MAINTENANCE
Sensor-driven servicing · MTBF 1.8× · MTTR 0.5× · Normal demand

Work-item flowing Idle machine Machine running Broken down (repair) Scheduled service
Buffer backing up (blocked) Squares = units; the column between two machines is the finite buffer One 8-hour shift (480 min) compressed into ~33 s at default speed · 8 serial stages: Raw Prep → CNC → Precision Machining → Sub-Assembly → Inspection → Surface → Final Assembly → Packaging · Finite buffers cause blocking; breakdowns idle a machine and back the line up · Fixed seed: identical result on every reset · KPIs (throughput, OEE, cycle time, unit cost) are illustrative animations calibrated to the Monte Carlo report, not a re-run of the full DES
