在水桶大队生产系统中，当工人们步行去从同事那里得到更多的工作时，他们进行的是非生产性的旅行。我们引入了一种新的斗式挖掘机设计，以减少非生产性的行程。根据新的设计，每个工人在一个方向前进时在通道的一侧工作，而在相反方向前进时在另一侧工作。我们提出了简单的规则，工人分担工作下的新设计，并找到了系统自平衡的充分条件。数值例子表明，通过新的设计，吞吐量的改善可以高达30%。即使减少了20%的劳动力，新的设计仍然可以增加7%的吞吐量。
Workers in a bucket brigade production system perform unproductive travel when they walk to get more work from their colleagues. We introduce a new design of bucket brigades to reduce unproductive travel. Under the new design, each worker works on one side of an aisle when he proceeds in one direction and works on the other side when he proceeds in the reverse direction. We propose simple rules for workers to share work under the new design and find a sufficient condition for the system to self-balance. Numerical examples suggest that the improvement in throughput by the new design can be as large as 30%. Even with a 20% reduction in labor, the new design can still increase throughput by 7%.
