“…In the RP, the fault-tolerant procedure (which is discussed in Section 3) is executed. The fault-tolerant procedure is a sequence of operations executed by the RD to detect and counteract faults on the basis of calculation results from the computers 26 .…”

“…The functional scheme of the RD is shown in Figure 4. The RD executes the fault-tolerant procedure in five steps 26 One contribution of this paper is a proposed non-trivial sequence of steps in which determining the fault type (step 2) and the recovery of the computational process after a temporary fault (step 3) are realized before fault localization (step 4). When a temporary fault occurs in the DCS, the faulty computer is not localized but masked.…”

In this paper, we propose an architectural design for a dual computer system (DCS) that operates in real-time with the fault-tolerance implemented purely by hardware. We have a novel design allowing the implementation of hardware that performs the following key services: the determination of fault type (temporary or permanent) and the localization of the faulty computer without using self-testing techniques and diagnosis routines. We also propose a non-trivial sequence of services for fault-tolerance in which the determination of the fault type and the recovery of computational processes after a temporary fault are realized before fault localization. Our design has several benefits: the designed hardware shortens the recovery point time period; the proposed non-trivial sequence of fault-tolerant services reduces (to two) the number of logical segments that should be re-run to recover the computational processes; and the determination of the fault type allows eliminating only the computer with a permanent fault. These contributions bring both an increase in system performance and an increase in the degree of system reliability.

The recently completed volume of Quality and Reliability Engineering International is its 25 th anniversary. The mission of the journal is to provide information on new developments in many aspects of the discipline to professionals with research articles, review papers, and applications and case study papers. It is appropriate to look back over this anniversary volume and identify some important themes, highlight some of the significant papers that contribute to those themes, and discuss what we hope to see in the future.Statistical Process Control (SPC) and related topics continue to be an important area of research and applications. The journal published many noteworthy papers in this area, including the papers on adaptive procedures by Li et al. 1 and Kooli and Liman 2 , run-to-run control 3 , integration of SPC with other techniques 4, 5 , design of control charts 6, 7 , and methods for identifying the change point in high-yield processes 8 .Reliability engineering and the associated statistical methods continue to be a key focus area for the journal. Koka et al. 9 present an interdisciplinary approach to reliability in design and Samet 10 discusses fault-tolerant computing. Accelerated life testing techniques are discussed by Liu and Tang 11 and Pan 12 . Remenyte-Prescott and Andrews 13 present a new real-time method for the efficient analysis of non-coherent fault trees. Anderson-Cook et al. 14 investigate resource allocation for a complex system with aging components.Designed experiments and robust design are an integral part of both product design and process improvement. Methodology for robust product or process design is considered by Shaibu et al. 15 , Steenackers et al. 16 and Rodriguez et al. 17 . Hazelrigg 18 discusses many interesting aspects of engineering design. Other extremely useful papers include Gaudard et al. 19 on the interaction between data mining and designed experiments, Guo et al. 20 on the general balanced metric for mixed-level fractional factorial designs, Wesley et al. 21 on prediction variance in split-plot designs, Guo et al. 22 on optimal fold-over designs for mixed-level fractional factorial designs, and Jones and Johnson 23 on designs for computer experiments.The journal also presented several interesting case studies, including Monroe and Pan 24 , Carmignani 25 , Magniez et al. 26 , Johnson et al. 27 and Aksoy and Orbak 28 . Case studies are an important part of this journal. We have a high standard for these papers. They must represent the best of contemporary practice either through the application of new methodology or the application of existing methods in unique environments. Quality and reliability engineers are knowledge workers. They accumulate, generate and deploy knowledge with the express objective of improving products, processes, services and society. Case studies facilitate the generation and widespread adoption of new methods or provide insight about how existing methods can be used in novel situations. These types of papers can perform a valuable service to...
