English System
The system of measurement units based on the foot, the pound, and the second. See also measurement.
Evolutionary Operations (EVOP)
A procedure to optimize the performance of a process by making small, known variations in the parameters entering the process and observing the effects of the variation on the product. This seems identical to Response Surface Methodology, except that it is done in a production situation rather than during process development, and the variations must, therefore, be kept small enough to meet product tolerances.
Exponential Distribution
A probability distribution is mathematically described by an exponential function. Used to describe the probability that a product survives a length of time (t) in service, under the assumption that the probability of a product failing in any small time interval is independent of time.
