Fault tree analysis (FTA) is a technique widely used in the study of the reliability of industrial systems and to quantify risks associated with potentially hazardous systems. Most of the studies carried out are related to how to construct a fault tree and how to carry out qualitative and...

Software testing is usually a very costly and time‐consuming phase in software development. As most software systems are modular, it is of great importance for the management to allocate the limited testing‐time among the software modules in an optimal way so that the highest quality and...

The ability of a company to achieve excellence in service quality depends on the determination of service attributes and their desired levels. It depends also on the prioritization of service attributes, using appropriate quality improvement indices, in a consistent manner within the constraints...

Control charts based on geometric distribution have shown to be useful when this is a better approximation of the underlying distribution than the Poisson distribution. The traditional c ‐chart, if used, will cause too many false alarms. It is noted that for geometric distribution, the control...

Presently, there is much focus on measuring and improving the quality of industrial systems with little attention paid to the quality of information technology (IT) related systems. In this paper, we present a study using the technique quality function deployment (QFD) to design and improve IT...

Traditional attribute control charts are based on the monitoring of the number of nonconforming items in a sample of fixed size. In modern manufacturing processes, since items can be checked automatically, use of samples of a fixed subjective size with traditional charts is not suitable for...
