• Abstract:
  This report contains the results of a pilot study accomplished to demonstrate the ability to determine the magnitude of software reliability encountered in large-scale computer-based equipment. The engineering model of the Discrete Address Beacon System (DABS) currently undergoing development was used as the subject. Based on software failure and test time data, a software reliability model was developed for the mode 1 of DABS and used to software reliability and its growth engineering measure during the debugging process. The software reliability model was merged with the hardware reliability model into a DABS system model suitable for prediction. The Mean Time Between Failures (MTBF) determined by this study applies only to an early version of the software associated with the engineering model of the DABS. The also includes recommendations for the specification of software reliability and the modification to the failure reporting system.
