Reliability Control Model for Stored Items Requiring Rework.

Abstract

An application of control theory to an administrative problem is given for the case of a system of stored items which are periodically reworked to improve their reliability. Expressions are developed for the final value of the reliability when the system is stable and the limits of stability are found. A Kalman filter is used in the control model to obtain an estimation of the item reliability when there are random errors in the measurement and in the rework process. An extension is done for more than one dimension for systems composed of subsystems in series, parallel or a combination of both. A procedure for an optimal sequence of levels of rework is found in the sense of optimizing a linear combination of several performance measures. Numerical examples are presented to demonstrate the use of the several expressions. (Author)
