    Reliability evaluation of real engineering systems is often performed using simulation tools. In general, to determine the state of the system (operating or failed) as a function of its components, it is necessary to evaluate a function that is called system function or structure function (SF). In a Monte Carlo simulation, system reliability is evaluated by generating at random several systems sta... View full abstract»

    This paper outlines a new approach for accurately evaluating the reliability of a complex, highly reliable system for which neither analytical methods nor conventional simulations are feasible. The reliability is simulated in a feasible parameter region, and then rational interpolation (RI) is used to calculate the desired reliability. Numerical experiments are presented to validate the feasibilit... View full abstract»

    The maintenance of any system can be categorized in two ways: failure based maintenance (corrective maintenance) and life based maintenance (preventive maintenance). The time interval at which the preventive maintenance could be scheduled is dependent on both the life distribution of the subsystems/components and the total cost involved in the maintenance activity. However, the corrective maintena... View full abstract»

    Reliability and maintenance are not direct customer requirements. Rather, customer requirements should be expressed in terms of the benefits reliability and maintenance can deliver. Customer requirements are generally maximisation or minimisation of scenario objectives such as safety, operational success and whole-life costs. Identification of the single technical solution that best achieves these... View full abstract»

    Several examples are presented to show how some development of reliability analysis methods has led to a resurgence of mistakes and pitfalls, which were believed to have been resolved a long time ago. A review of those cases indicates that the major cause of this undesirable outcome is the emphasis on procedures, while overlooking the importance of definitions and basic concepts, including the sta...

    Conceptual design's intrinsic uncertainty and influence on product life cycle cost make reliability engineering tools during early design phases important. However, typically poor knowledge bases make the prediction of component failure and system performance challenging. Fuzzy techniques are used here during initial conceptual design stages to quantify imprecision and uncertainty in reliability a... View full abstract»

    Two graphical techniques for analyzing step-stress Arrhenius exponential data are presented and compared to maximum likelihood estimation using simulated data. Analysis shows that the graphical technique using least squares estimation is unbiased. Levene's test for equality of variance also shows that the least squares estimator is as efficient as the maximum likelihood estimator. An analysis of o... View full abstract»

    Often the purpose of performing a qualitative hazard analysis is to judge the acceptability of, or offer improvements to, an engineered system. Many papers and techniques exist that describe the well-defined hazard analysis philosophy of (1) defining the hazards, (2) identifying the potential accident scenarios and causes, and (3) listing the preventive and mitigative safeguards. However, qualitat... View full abstract»

    This paper presents a methodology associated to a software tool to generate fail-safe VHDL synthesizable descriptions from Petri net or state diagrams. With this philosophy of automatically providing safety to VLSI systems design in VHDL, designers do not have to include the error detection system because it is going to be added automatically in the design. The method is explained as a group of se... View full abstract»

    The accelerated life tests can obtain information on lifetime characteristics of products quickly. Then, the products can be submitted to higher levels of stress in various ways such as constant, step, and progress stress. In a constant-stress model, products are run under a constant level of stress until all products fail or a time limit is reached. A step-stress model allows the stress setting t...

    The idea of nested renewal processes is used to define availability models for equipment subjected to age-based opportunistic preventive maintenance policies. The description of equipment behavior in terms of sample paths that do not result in opportunistic replacement leads to compact models of system availability. The models are expressed in terms of the policy parameters. Core model analyses ar... View full abstract»

    In train and transit applications, the occurrence of a single hazard (fault) may be quite catastrophic resulting in significant societal costs, ranging from loss of life to major asset damages. The axiomatic safety-critical assessment process (ASCAP) has been demonstrated as a competent method for assessing the risk associated with train and transit systems. ASCAP concurrently simulates the moveme... View full abstract»
