    Generally, most circuit packs of telecommunication systems are processed through a manufacturing test process that may include in-circuit test, functional test, factory environmental stress testing or environmental stress screening (ESS), and system tests. Some of these tests, like ESS, may also be due to customer or Bellcore requirements. However, it is both expensive and time consuming to proces... View full abstract»

    Conventional failure effect analysis depends on the expert's judgement and experience, which may lead to an erroneous result. To solve this problem, this paper proposes a failure effect analysis using bond-graphs, which represent the system behavior in a unified way from the viewpoint of energy flow. The system state equations obtained from a system bond-graph represent the system behavior in the ... View full abstract»

    Publication Year: 1999 , Page(s): 69 - 77
    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (456 KB)  

    This paper examines the problem of determining and evaluating optimal fixed-length inspection intervals for a single machine that operates continuously subject to nonobvious, random failures. Good-as-new repairs are performed when the machine is found to be failed. Both the fixed-interval inspection and replacement times are instantaneous. Two possible single parameter failure time distributions a... View full abstract»

    The classical approach to the calculation of reliability characteristics is based on the probability distribution of time to failure. Recently, a new approach based on relevant condition parameter was introduced, which describes the condition of the system and calculates the reliability characteristics at every instant of operating time. A condition parameter could be any characteristic such as cr... View full abstract»

    The unreliability of a two component parallel system with Weibull component failure distributions is analyzed. The system operates in discrete duty cycles and is repaired only between duty cycles. A complex repair strategy embodying both scheduled maintenance and unscheduled, deferred maintenance is considered. System unreliability is computed by two methods. The first method is based on the renew... View full abstract»

    The development of multilevel accelerated life stress tests has been hindered by the difficulty of performing adequate and satisfactory data analysis. When 2, 3 or 4 levels of stress exist, even a computer analysis can be formidable. Nelson (1990) showed that even a simple analysis of seven levels of a single stress can become quite a challenge. This paper shows a new computerized software approac... View full abstract»
