    Publication Year: 2008, Page(s):1 - 7
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (491 KB) | HTML iconHTML

    Many systems are multi-phase mission systems. During different phases, the system reliability configuration, reliability requirements and operation environment can be different. For example, some components may change from active status to standby or the system reliability configuration may change from serial to parallel. In addition to configuration changes, the system may be exposed to different... View full abstract»

  • A systems reliability approach to decision making in autonomous multi-platform systems operating a phased mission

    Cited by:  Patents (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (312 KB) | HTML iconHTML

    This paper presents a decision making strategy for autonomous multi-platform systems, wherein a number of platforms perform phased missions in order to achieve an overall mission objective. Phased missions are defined for both single and multi-platform systems and a decision making strategy is outlined for such systems. The requirements for a tool performing such a strategy are discussed and metho... View full abstract»

  • Risk analysis of phased-mission systems with multiple failure modes

    Publication Year: 2008, Page(s):15 - 20
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (300 KB) | HTML iconHTML

    General systems such as production plants and aircrafts can be regarded as a phased-mission system, which perform several different functions depending on their operation stage. This paper proposes a novel, simple and practical risk analysis method of phased mission systems with multiple failure modes. Firstly, based on the physical definition of a system accident, system accident occurrence condi... View full abstract»

  • Reliability analysis of phased-mission systems using Bayesian networks

    The paper presents a Bayesian networks (BN) based method to analyze the reliability of phased-mission systems (PMS). The method includes three steps. Firstly, each phase of PMS is represented by a BN framework, named phase-BN. Then, in order to express the dependences across phases, all the phase-BN are combined by (1) connecting the root nodes that represent the same component but belong to diffe... View full abstract»

  • Optimal highway maintenance policies under uncertainty

    Publication Year: 2008, Page(s):25 - 30
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (520 KB) | HTML iconHTML

    We develop an inspection and maintenance policy to minimize the cost of maintaining a given section of road or highway when there is a great deal of uncertainty in the degradation process. We propose to model the degradation of a section of road based on the proliferation and growth of cracks. We utilize a combination of a Poisson and gamma process to account for the tremendous amount of uncertain... View full abstract»

  • A study on optimal age replacement of dozer engines

    In this paper, the concepts and methods of total time on test (TTT) plots are discussed. The failure data of two groups of electro-mechanical equipment (indigenous and imported dozer engines) are used to draw TTT plots, which indicate health of equipment in terms of failure rate. The optimum replacement interval is obtained for the equipment with increasing failure rate depending on the type of th... View full abstract»

    The overall objective of design for reliability is to ensure that the final product will be economically reliable. This means that the product's observed reliability has been established with consideration of life cycle costs. These costs include the acquisition cost, scheduled maintenance cost, unscheduled maintenance cost and the cost of failures. Cessna Aircraft Company has developed a model th... View full abstract»

  • Uncertainty in Life Cycle Cost of railway track

    Publication Year: 2008, Page(s):42 - 47
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (319 KB) | HTML iconHTML

    Life Cycle Cost (LCC) is used as a cost effective decision support for maintenance of railway track infrastructure. However, a fair degree of uncertainty associated with the estimation of LCC is due to the statistical characteristics of Reliability, Availability and Maintainability (RAM) parameters. This paper illustrates a methodology for estimation of uncertainty linked with LCC, by a combinatio... View full abstract»

  • A methodology for managing reliability growth during operational mission profile testing

    It is common practice for systems to be subjective to operational testing during their development program. The objective of this testing is to evaluate the performance, including reliability, of the system under conditions that represent actual use conditions. Because of expense, resources, schedule, and other considerations, these operational tests rarely represent exactly the actual use conditi... View full abstract»

  • An age-adjusted comparison of field failure data for repairable systems

    Publication Year: 2008, Page(s):54 - 58
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (329 KB) | HTML iconHTML

    The conventional calendar-based mean cumulative function (MCF) plot is useful in monitoring the field reliability of a population of repairable systems deployed in a large quantity. It is simple and easily understood by management. However, it is age-confounded when the system population is heterogeneous with age. Assuming that the systems follow the well-known ldquoBathtubrdquo behavior, the popu... View full abstract»
