Software Reliability Analysis using Queuing-based Model with Testing Effort

Abstract

In this paper, we investigate software fault detection and fault correction processes based on infinite server queuing model which incorporate testing effort functions. Some researches proposed in the literature to study fault detection and fault correction processes. However, most of them do not consider the amount of resources consumed during fault detection and fault correction processes. The consumption amount of resources is usually depicted by testing effort functions which can largely influence fault detection speed and the time to correct a fault detected. Therefore, we will show that new models incorporate testing effort functions into the fault detection and fault correction processes. In additional, we study how to use queuing models to explain the fault detection and fault correction processes during software development. Parameters are estimated and experiments on actual fault data sets are illustrated. The results show that the proposed models in this paper can estimated the number of initial faults better than the model without testing effort functions..
