Observed decision problem
Weak or wet board, poor score geometry, unsupported corners, excessive stacking, pallet gaps or unstable unit-load restraint can collapse cases. Follow the disturbance upstream and downstream through preparation, treatment, buffer, filler, closure, inspection, conveyors, packing and utilities. Synchronize clocks and include starts, short stops, speed changes, material replenishment, cleaning, maintenance and operator interventions. Review startup, steady production, short stops, restart, low or high demand, format or recipe change, cleaning and shutdown. The interface must protect both the incoming condition and the requirement of the next module.
