    Redundant aircraft systems are intended for operation under established flight missions and maintenance programs. Systems may have latent failures and their reliability may vary, depending on previously made scheduled checks and repairs. System failure modes are a basis for assessing failure effect on flight safety, and are determined by the components' failure modes and their sequence of occurren... View full abstract»

    Despite the fact that it is extremely early even in the definition of reliability and maintainability targets for the RAF's Future Offensive Aircraft (FOA), the support vision is looking for an aircraft which will have guaranteed periods of availability by staying serviceable, requires only a few maintenance personnel, needs little in the way of specialized support and aircraft ground equipment (A...

  • Equipment performance monitoring: a Canadian Air Force perspective

    Publication Year: 1997, Page(s):37 - 43
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (684 KB)

    The in-service management of any equipment requires an understanding of not only the inherent reliability performance of the equipment, but also the way this performance changes with time; this is particularly true with complex repairable items. Without accurate information about the expected reliability performance of an item, it is not possible to predict the logistics resource (i.e. spare parts... View full abstract»

  • IQLM: application for rail systems

    Publication Year: 1997, Page(s):333 - 338
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (504 KB)

    Cost-effectiveness is an evaluation involving both performance and cost. The best performing rail system may not be the most cost effective one. Therefore, when analyzing the acquisition of a rail system, both performance and cost must be considered. The integrated quality and logistics management (IQLM) methodology presented in this paper demonstrates how to evaluate cost-effectiveness for a syst... View full abstract»

    In this paper we present a method for handling big Markovian graphs for reliability studies. If the model is Markovian, it is theoretically possible to generate and quantify the state graph. However, it is often not feasible, because of the number of states. One possibility, in the case of a reliability study, is to generate paths leading from the initial state of the system to the failure state. ... View full abstract»

  • Numerical techniques for assessing reliability and performance of gracefully degrading computer systems

    Publication Year: 1997, Page(s):159 - 163
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (412 KB)

    Gracefully degrading systems represent a cost effective alternative to the massively redundant fault-tolerant computing systems. Assessing the effectiveness of these systems requires combined reliability and performance measures such as computational availability, performability and accumulated reward. This paper compares, for the first time, two numerical algorithms used for assessing the complem... View full abstract»

    One of the primary effects of acquisition reform has been to inject uncertainty into the procurement process for both the US Department of Defense (DoD) and its contractors. Of particular concern is the quantification of reliability performance and risk assessment for commercial off-the-shelf (COTS) equipment that is targeted far use in environments more severe than that for which it was originall...

  • Reliability design based on dynamic factorial experimental model

    Publication Year: 1997, Page(s):320 - 326
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (508 KB)

    This paper discusses how to apply the fractional factorial experiment method to degradation testing and reliability design. The static fractional factorial experimental model is extended to the dynamic fractional factorial experimental model. In data analysis, we suggest using degradation measure and safety margin function Z(t) as the response variable. Z(t) is similar to the signal-noise-ratio de... View full abstract»

    The existing classes of software reliability models require an a priori distribution for collected data in their analysis. Using these models, analyses can be performed using various assumed distributions. The assumed distributions may not accurately reflect the behavior of the collected data, and as a result, the results predicted by the models can be quite inaccurate. If it is assumed that the o...

    Accelerated life tests were used to estimate s-failure rates for PolySwitch polymer-based positive temperature coefficient (PPTC) devices with a surface-mount configuration. Electrical tests were done on a lot inspection basis on production parts, and results were pooled. Using an exponential model, the estimated failure rate from the pooled data is about 0.8 to 3.0 failures in time (FIT). Product... View full abstract»

    This paper describes a heuristic optimization approach using genetic algorithms. The method solves general network design problems to optimality, or near-optimality, with respect to reliability. The optimization formulation in this paper relaxes the previous restrictions that appear in the literature. Network design is expanded to include links of differing reliability and to select from multiple ... View full abstract»

    In the absence of military reliability performance verification standards, the author proposes one way of implementing reliability performance accountability. The proposal consists of incorporating a real-time reliability meter (RTRM) into critical military equipment, particularly commercial off-the shelf (COTS). The methodology used in this paper results in an equation that depicts the observed f... View full abstract»

    This paper presents and evaluates an approach to designing accelerated life testing (ALT) experiments. We believe that knowing the design limits of the test item is critical to successful ALT. Unfortunately, effective methods do not exist for analytically predicting the design limits of most electronic items; therefore, the basis of our approach is a destructive evaluation performed on a small num...

    This paper presents a methodology and supporting set of tools for performing fault simulation throughout the design process for large systems. Most of the previous work in fault simulation has sought efficient methods for simulating faults at a single level design abstraction. This paper has developed a methodology for performing fault simulation of design models at the architectural, algorithmic,... View full abstract»
