02 / Complete-line interfaces
Design normal production and the conditions that disturb it
Production can continue on ambiguous status, inconsistent methods or delayed results unless tanks, orders and batches have controlled disposition rules. Trace the material from receiving and storage through preparation, dosing, mixing, transfer, treatment and filler feed. Include startup, recirculation, low-level conditions, recipe changes, flushing, cleaning, off-spec diversion and the data exchanged between each module. 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.
