1) Seasonal relatives can be used to deseasonalize data or incorporate seasonality in a
forecast.
2) Ergonomics is important for preventing common workplace injuries such as back
injuries and repetitive-motion injuries.
3) The process capability index (indicated by Cpk) can be used only when the process is
centered.
4) Capacity increases are usually acquired in fairly large “chunks” rather than in smooth
increments.

grinders are grouped into a cell).
8) The four building blocks of lean operations are: product design, process design,
personnel/organizational elements, and manufacturing planning and control.
9) Queue discipline requires a security presence to maintain order.
10) If the majority of service customers are satisfied, it is likely that all service
customers will be satisfied.

C.a smooth, rapid flow of materials through the system.
D.no setup times.
E.all of the choices.
