One way to coordinate workers along an assembly line that has fewer workers than work stations is to form a bucket brigade. The throughput of a bucket brigade on discrete work stations may be compromised due to blocking even if workers are sequenced from slowest to fastest. For a given work distribution on the stations we find policies that maximize the throughput of the line. When workers have very different production rates, fully cross-training the workers and sequencing them from slowest to fastest is almost always the best policy. This policy outperforms other policies for most work distributions except for some cases in which limiting the work zones of workers produces higher throughput. In environments where the work can be adjusted across stations, we identify conditions for a U...
Assembly lines function best when every worker is present. When a worker is absent, management must scramble to quickly find a replacement. Usually, the replacement will not be as proficient as the absent worker. This can reduce quality and throughput. We present two assembly line work-systems models (one for lines with Andon and one for lines without Andon) that show one mechanism whereby absenteeism could impact quality and throughput. We exercise these models to provide insights into absenteeism's impact on quality and throughput. While the paper is written in the concrete terms of automotive assembly, the concepts and results apply to manual assembly lines in general.

As Labor Secretary, I often think about the classic American "supermom." For many, what comes to mind is a busy executive; a woman who can handle a work crisis, a sick kid, a soccer game, and making a meatloaf all at the same time. It seems like magic. And then I think about my mother - a different kind of supermom. With seven children, she sewed, cleaned and cooked in the morning, and worked at a local toy factory at night. Balancing work and family wasn't something she thought about or debated. She just did it. And I had to help. I remember helping my mom cook, clean and even change diapers for my siblings. In many ways, I was her "deputy. All of us want to care for our loved ones. And we want to be good at it. We want to do well at work and care for our families, whether that means ...

In what will probably look like speed-dating for politicians, each of the 40 candidates vying for a spot on the Independent Redistricting Commission will have just a few moments to impress a selection panel during its next meeting Dec. 8. The Commission on Appellate Court Nominees decided Nov. 16 that an assembly-line approach of rushed interviews would work better than no interviews prior to choosing a final list of 25 nominees for the Redistricting Commission, which will be in charge of re-drawing Arizona's legislative and congressional maps.
In the old days, business owners allowed employees who were volunteer firefighters to drop what they were doing and run out the door when the fire alarm downtown wailed. But today, as the city grows and its industries expand and modernize, that is not always the case. With factories becoming leaner to be more competitive, the sudden absence of a line worker who doubles as a firefighter can bring an entire assembly line or work station to its knees, resulting in lost productivity and income.
Boeing Co., facing a federal labor complaint hearing next week over its new 787 Dreamliner assembly line, is already being pressured by politicians and unions interested in work on a subsequent generation of airliners. While the planemaker held a ribbon-cutting ceremony Friday for the 787 plant in South Carolina, Washington state has begun working to secure production for Boeing's upcoming single-aisle jet. The South Carolina plant at the center of the National Labor Relations Board complaint is the first commercial factory Boeing has built outside Seattle, where it was founded in 1916.
BANCROFT - For Clark International employee Bob Ellswick, a $5.1 million contract to refurbish armed personnel carriers brings his career full circle. In the early 1960s Ellswick worked on the assembly line at FMC Corp.'s South Charleston Ordnance Center. "I went to work there in 1963 when I was 21 years old," he said. "I worked there a couple of years. They made M113s - armored personnel carriers - in the first building (closest to McCorkle Avenue). They made M110s - mobile gun platforms - in the second building.
MORAINE -- The future is literally now for General Motors Corp. and production workers at its Moraine Assembly plant. Local 798 of the International Union of Electronic Workers-Communications Workers of America is talking with GM about prospects for work at Moraine after the plant's current production assignment for sport utility vehicles ends in 2008. The talks are taking place against a sobering backdrop: GM's announcement last week that it will end the plant's overnight shift after June 30, taking with it 1,150 of the plant's approximately 4,100 jobs. And GM shut down a sister SUV plant in Oklahoma City last week.
PLATTEVILLE, Wis. - Kathy Cushman was just a kid out of high school when she started working on an assembly line in the lacing department, working on wire. It was hard work. Hot work. Routine- ridden. Mind-numbing. Taxing on the back. I could feel all 13 years there," Cushman said of her time at Advance Transformer in Platteville.
