Operations

One flow unit every x minutes - not always possible, setup, variability in processing time and quality levels interfere with the possible flow

no production taking place during setup time, e.g., retooling machines, time before one set of customers exit & next are served, etc.

• batch size                                     
• setup time+batch size+time per unit
• =capacity given batch size

• s=setup time (higher setup time, smaller capacity)
• b=batch size (# of units processed before incurring a setup)

• B         
• S+B x p
