A linear combination software reliability modeling tool with a graphically-oriented user interface

Abstract

Previously the authors have shown that forming linear combination of model results tends to yield more accurate predictions of software reliability. Using linear combinations also simplifies the practitioner's task of deciding which model or models to apply to a particular development effort. Currently, no commercially available tools permit such combinations to be formed within the environment provided by the tool. Most software reliability modeling tools also do not take advantage of the high-resolution displays available today. Performing actions within the tool may be awkward, and the output of the tools may be understandable only to a specialist. They propose a software reliability modeling tool that allows users to formulate linear combination models, that can be operated by non-specialists, and that produces results in a form understandable by software developers and managers.<>
