    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»

    Software users are interested in the MTTF value of software. The rules of λ Pareto diagrams are in general quite different from one software to another. We cannot get an analytical expression to describe the pattern of λ Pareto diagram and be generally suitable to all software. We have constructed a software reliability testing platform (SRTP) which can automatically produce random i... View full abstract»

    Variability analysis or error analysis is a technique by which one can determine, with good approximation, whether a system will work within the specification limits when the part parameters vary between their limits. Classical methods of variability analysis include: worst-cast, probabilistic transformation of variables, method of moments and Monte Carlo. This paper shows the use of interval arit...

    Recent developments in reliability modeling and computer technology have made it practical to use the Weibull time-to-failure distribution to model the system reliability of complex fault-tolerant computer-based systems. These system models are becoming increasingly popular in space system applications as a result of mounting data that support the decreasing Weibull failure distribution and the ex...

  • 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»

    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...

    concurrent engineering (CE), or integrated product development, is a US Department of Defense (DoD) initiative for the defense industry; it has also been used very successfully by commercial industries. CE is applicable to any industry that develops its own products and wants to remain competitive in today's marketplace. The computer-aided acquisition and logistics support (CALS)/CE Industrial Ste... View full abstract»

  • The case for architecture-specific common cause failure rates and how they affect system performance

    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (584 KB)

    In redundant systems composed of identical units, common cause failures can significantly affect system performance. We show that the probabilities of common cause failure are architecture specific. We derive the probabilities for generalized dual and triplex systems. We analyze and compare three common architectures, i.e., 1oo2, 1oo2D and 2oo3, to determine the effects of common cause failure on ... 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»

    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»

    The goal of the DARPA/Tri-Service-sponsored Rapid Prototyping of Application-Specific Signal Processors (RASSP) program is to reduce the cost and time to develop and manufacture signal processors by at least a factor of four. Lockheed Martin Advanced Technology Laboratories' (ATL) approach to reaching this goal is based on three thrusts: methodology; model-year architecture; and infrastructure (en... View full abstract»

    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»

    This paper considers the problem of estimating the captive-carry life length of a missile from highly censored data. The captive-carry life length of a missile is a “measure of the cumulative time a missile can be carried by an aircraft in-flight and still remain launch capable”. This paper explores several different methods for analyzing the captive carry data set View full abstract»

    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»

    This paper considers distributed multisensor applications, and finds redundant configurations that minimize system weight or cost while insuring system dependability. Given choices among different component types, fulfilling the system's operational requirements but having different dependability parameters and per item cost, two heuristics, one nonmonotone (tabu search) and one monotone (simulate...
