Title: Finite-Sample Properties of a System of Softwares
Author(s): Marcus A. Agustin*+
Companies: Southern Illinois University
Address: Dept. of Mathematics and Statistics, Edwardsville, IL, 62026-0001,
Keywords: counting process ; maximum likelihood ; software reliability
Abstract:

This paper considers a system of softwares where each software failure rate follows the model by Jelinski and Moranda (1972). At any time t, each software failure depends on the residual number of bugs with each bug contributing the same amount to the failure rate of the software. Tasks are assigned to the system where the task completion times are independent of the software failure times. The system is observed over a fixed testing period and an estimator of the system reliability upon test termination is presented. The finite-sample properties of the system reliability estimator are examined via a simulation study.
