Abstract
“Tolerance design” refers to the selection of specifications for individual components using formal optimization. Specifications might relate to the acceptable length of a shaft, for example, or the acceptable resistance of a specific resistor in a printed circuit board. Choices about the specifications are important in part because conforming component parts can cause the entire engineered system to fail to conform to specifications. Also, sometimes the specification limits may be needlessly “tight” requiring expensive manufacturing equipment that does not benefit the customer.
