ABSTRACT
Often, no one besides a few people knows how to perform setups because the procedures are difficult, arcane, and require special skills. Reliance on only a few people for setups, however, increases the average setup time because, often, machines in need of changeover must sit idle until the setup person finds time to come over and change them. Typically, any operation that requires long setup time is accompanied by large production runs so that the setup occurs infrequently and the setup cost is distributed over a large number of units.
