A difference exists between the software testing environment and operating environment, which has a crucial impact on the software reliability assessment, testing costs and optimal release time. The software cost model is an effective tool used to help software developers control software costs and determine the release time. However, the current studies have not taken the difference of the environment...
Using advantages of priori Bayesian method, a reliability verification test method based on Hybrid Bayesian Prior Distribution was brought forward. The prior distribution of unknown parameters can be obtained by using conjugate prior distribution method. Prior moment method and Maximum entropy method were used respectively to calculate two different groups of parameters, and then two different prior...
For increasing the effectiveness and efficiency of the software reliability testing, a two-stage combined software reliability accelerated testing is proposed. The combined testing method combines representative testing and directed testing, and it is able to test some operations or program modules with low operation frequency to satisfy the coverage criteria if the number of the test cases is the...
Applications of existing architecture-based software reliability models are strictly limited to software in which the component transitions satisfy the Markov properties. When software has both deterministic and probabilistic behaviors, these models intentionally model it as Markov process, of which the reliability estimation with lowered accuracy comes as a result. The objective of this paper is...
Application of existing architecture-based software reliability models is strictly limited to software in which the component transitions satisfy the Markov properties. When software has both deterministic and probabilistic behaviors, these models intentionally model it as a Markov process, of which estimation of reliability with poor accuracy come as a result. The objective of this paper is to present...
COTS (commercial off the shelf) component products undergo a technology refresh and renewal cycle. New versions or releases of COTS component products are brought to the market frequently. And rapid evolution of the COTS component product means the obsolescence of the COTS-based systems, especially during COTS-based systems' maintenance (in a long run). This is the fundamental problem to application...
