Balancing
The Work In Workcells
Cellular
Manufacturing and workcells play a primary role in many Lean
Manufacturing strategies. They appear simple, at first glance. In
reality, they are complex, sophisticated and,
sometimes, delicate socio-technical
systems. Optimum workcells require careful design by
teams with a deep understanding of their subtleties and nuance.
Work
balance is one design issue. Many who are familiar with Ford
production lines attempt to balance the time at each workstation.
But this is only one of several methods that are available. This
"inherent" balance method is difficult with dedicated cells
and lines. With mixed-model and GT cells,
inherent balance is usually not feasible.
Other
methods include Circulation (also
known as chaku-chaku) and floating balance.
Our web page, Balancing Workcells,
examines this issue and shows the various methods for balancing both
machines and people.
Our
next issue of Lean Briefing deals with Takt
time and other time elements for designing cells. See you
then.
