This paper presents a simple method for evaluating the effectiveness of testing strategies by using the relation between software reliability and software complexity. A wide range of metrics from the literature are being tested for their suitability in measuring changes in software complexity of software code at different levels of system partitioning. Reliability data from software tests and operational...
This paper provides a methodology to determine the reliability of a system, when only limited information about the system (in this case a patient table of a medical scanning system) is available. With this methodology, Bayesian inference, different sources of information (expert knowledge and field data) can be combined, and the uncertainty that is inherent to reliability prediction when only little...
This paper addresses the problem how to represent diverse field usage of professional systems in an efficient way, so that field usage can be incorporated in reliability tests. With diverse we mean the variability in system use in the field. Operational profiles are constructed from system field data to represent system field use. A clustering technique is introduced and applied in a strategic way...
In innovative fast product development processes is it necessary to determine as fast as possible whether the product reliability is at the right level. This paper describes analyses of field data for several apparently similar systems during the warranty period. The paper considers the adequacy of the widely used non-homogeneous Poisson process with different intensity functions. The non-parametric...
