    This paper studies optimal (s,S) policies for production planning in manufacturing systems of unreliable machines in tandem. The manufacturing system produces one type of product. This type of manufacturing system occurs in many applications. In our study we assume that the inter-arrival time of a demand and processing time for one product in each machine are exponentially distributed. Each machin... View full abstract»

    Step-stress testing has a number of worthwhile applications for the analysis of the projected life for components and occasionally systems. These include the common situations of testing when only a small number of systems are available, when extremely long or specialized test equipment are required, when limited environmental chamber capability and/or test fixtures are involved, and lastly when v...

    A systematic accelerated stress testing approach, based on physics-of-failure (PoF) principles is presented for the reliability assessment of an avionics electronic module. Results from this case study demonstrate that combined accelerated stress tests may produce complex synergies that can only be controlled through precise PoF assessment. The paper concludes with a set of generic guidelines to d... View full abstract»

  • FMEA for multiple failures

    Publication Year: 1998, Page(s):43 - 47
    Cited by:  Papers (8)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1008 KB)

    Failure mode and effects analysis (FMEA) usually only considers single failures in a system. This is because the consideration of all possible combinations of failures in a system is impractical for any but the very simplest example systems. Even if simulation is used to automate the work of producing an FMEA report, consideration of all possible combinations of failures is not possible, and even ... View full abstract»

    High availability is driven by two types of factors: customer site factors such as the frequency of software and hardware upgrades, and system factors such as failure and repair rates, most often associated with mathematical models of reliability and availability. In this paper we describe several tools to assess the effects of these factors on the availability of high availability transaction pro... View full abstract»

    The topic of this paper is the optimization of inspection intervals for the motor-pump set of the AFW system (auxiliary feedwater system) in a nuclear plant. The report focuses on plain hydrodynamic bearings and thrusts. The bearings inspection task requires the disassembly of the pump which is expensive and has not proved to be necessary so far. This paper shows the advantages of the combined use... View full abstract»

  • An integrated safety-analysis methodology for emerging air-transport technologies

    Publication Year: 1998, Page(s):260 - 267
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (888 KB)

    We demonstrate an approach to integrating reliability, performance, and operational procedures modeling into a system safety analysis. Our methodology is distinguished by its ability to merge system design information with the dynamic parameterization of a system's situation in order to measure accident statistics and reliable system operation. As an application of this methodology, we have consid... View full abstract»

    A new damage accumulation approach presents an alternative interpretation for the bi-modality of fiber optics strength distribution. This approach is applied in order to improve the prediction of the mechanical reliability of optical fibers. The presented work shows that this approach can be used as an effective tool for the assessment of fibers strength dynamics. The data, obtained by simple tens... View full abstract»

    This paper considers the problem of estimating the survival function from a large set of sampling data subject to high levels of random censoring on the right. The system under study consists of a series arrangement of four functional subsystems. Each of the functional subsystems consists of a collection of independent components in series. The system does not have redundant components. This study... View full abstract»

    The need to reduce production costs through process streamlining is paramount in today's highly competitive environment. For ESS, this means that it must be justified in terms of the overall value it provides to the customer. Therefore, this paper addresses the problem of designing an ESS test strategy that is effective, yet makes efficient uses of test resources. The experiences described in this... View full abstract»

    In reliability engineering, it is known that electrical and mechanical equipment usually have more than one failure mode or cause. The mixed Weibull distribution is an appropriate distribution to use in modeling the lifetimes of the units that have more than one failure cause. However, due to the lack of a systematic statistical procedure for fitting an appropriate distribution to such a mixed dat... View full abstract»

    Just as estimates of cost and program timing are critical factors to be known and monitored during a new product development program, so too is the reliability perspective. This paper describes an approach to reliability modeling that encompasses the impact of both product and manufacturing process design on the distribution (characterizing the uncertainty) of reliability over time. It further des... View full abstract»
