In bucket brigade" manufacturing, such as recently introduced to the apparel industry, a production line has n workers moving among m stations, where each w orker independently follows a simple rule that determines what to do next. Our analysis suggests and experiments connrm that if the workers are sequenced from slowest to fastest then, independently of(More)
To construct a short tour through points in the plane, the points are sequenced as they appear along a spacefilling curve. This heuristic consists essentially of sorting, so it is easily coded and requires only <italic>O</italic>(<italic>N</italic>) memory and <italic>O</italic>(<italic>N</italic> log <italic>N</italic>) operations. Its performance is(More)
" Bucket brigades " are a way of sharing work on a flow line that results in the spontaneous emergence of balance and consequent high throughput. All this happens without a work-content model or traditional assembly line balancing technology. Here we show that bucket brigades can be effective even in the presence of variability in the work content. In(More)
We show h o w to minimize labor costs in a less-than-truckload LTL freight terminal by properly assigning incoming and outgoing trailers to doors. Our models are based on the geometry of the terminal, the material handling systems within, and the mix of freight passing through. We report on the application of our models at diierent terminals, including an(More)
We develop a heuristic for a problem motivated by the loading of aircraft or trucks: pack blocks into a bin so that their center-of-gravity is as close as possible to a target point. Our heuristic either produces good solutions or else signals that none is possible. It also works when loading non-homogeneous blocks into a bin of non-zero and possibly(More)
We show how to build a continuous, one-dimensional index of the points on a triangulated irregular network (TIN). The index is constructed by first finding an ordering of the triangles in which consecutive triangles share a vertex or an edge. Then, the space within each triangle is continuously indexed with a space-filling curve that begins at one vertex of(More)
To my parents for all their support iii ACKNOWLEDGEMENTS First and foremost, I would like to thank my parents for all their support during my time in graduate school. Without everything they have done for me during my time at Georgia Tech and well before, I would not have gotten to this point. I also want to thank my brother Chaim for his support. My(More)
