Opis

Inventor, and consultant John J Heldt introduces two new tables with the Poisson terms rearranged for estimation of the Distribution Tables. Heldt's two variations on the tables yield these results: estimations of product Mean Time Between Failures based on the life tests, plus development of the Operating Characteristics Curves for Life testing.

Recenzje

"…illustrations of this book enlightening and capable of providing quick solutions to immediate practical engineering problems as well as an improved understanding of statistical quality control. …makes reliability work much easier and can be used for quicker release of statistical information."
-Hoang Pham, Department of Industrial Engineering, Rutgers University, Quality Sampling and Reliability
