Bayesian Interactive Graphics Reliability Assessment Procedure (BIGRAP)

Abstract

BIGRAP is a package of interactive graphics programs, written for use on the TEKTRONIX 4014 Graphics Terminal connected to the ARRADCOM CDC 6500/6600 computer configuration. This package consists of a set of intricate programs that allows a user to input component success/failure data and a Boolean expression depicting system reliability logic for the purpose of assessing system reliability. The computer converts the logic expression to an algebraic expression for the system reliability as a function of the individual component reliabilities. A Bayesian statistical algorithm is then employed to provide the user with point and confidence interval estimates of system reliability. In addition the graphics feature of the package displays histograms and corresponding Beta distributions involved in the analysis. The programs are run sequentially as a cataloged procedure using the BEGIN/REVERT utility. This report is intended to serve as a guide to potential users of BIGRAP for operation and interpretation of results.
