What Is Line Balancing & How To Achieve It

Line balancing reduces variations within a production line. A balanced production line is stable and flexible enough to adapt to changes. For example, if customer demand changes–meaning takt time changes–operations can be realigned quickly through line balancing. The consequences of changes brought to a balanced production line are predictable.Line Balancing, Line Balancing Operations ManagementLine Balancing (Production and Operations Management) In production, line balancing is useful tool. Line-balancing strategy is to make production lines stretchy enough to absorb external and internal indiscretion. This strategy involves setting a planned rate of production for necessary materials to be fabricated within a particular time frame.
