Virtual Bookstore Citation Title COMPARISON OF LOG-GAMMA AND LIEBERMAN-ROSS LOWER CONFIDENCE LIMIT PROCEDURES ON SYSTEM RELIABILITY. Author(s) Maynard,Teddy Ray ; Corporate Author(s) NAVAL POSTGRADUATE SCHOOL MONTEREY CALIF Report Date 3/1/1977 Page Count 96 Abstract This thesis is an accuracy study of three empirical series systemlower confidence limit procedures. Computer simulations were used to compare theaccuracy of the procedures using the same set of data with 500 replications foreach case. Modifications were then made to improve the accuracy of the Log-Gamma method. The systems simulated had reliabilities ranging from .6 to .95.They were composed of four, fifteen, or forty components and had componentsample sizes of ten, twenty, or fifty. The Lieberman-Ross method was accuratebut had high variance. The Log-Gamma method was conservative with small samplesizes, but became more accurate with increased testing. Randomization of theLog-Gamma method was the most successful of the modifications attempted.(Author) Price: Available from National Technical Information Service (NTIS). http://www.ntis.gov   Prices are plus sales tax when purchased within New York State and shipping charges, if applicable
