    Phased array radar systems are used by the military for tracking targets and providing weapon engagement support. Each radar system consists of multiple antenna modules arranged in a 2-dimensional grid. An n-by-n antenna array radar system can operate with up to a given number of antenna module failures, with acceptable degraded performance, as long as the failed antennas are not adjacent to each ...

    Today's reliability methodologies and tools need to assess increasingly large, complex systems. Moreover, in order to adequately evaluate the system dependability it is necessary to take into the right consideration system dynamics. Combinatorial techniques can be adopted in case the system's units are two-state (Boolean) and stochastically independent. Otherwise, it is requested to recur to lower... View full abstract»

    Maintenance management often focuses on the minimization of the repair cost and the part replacement cost. In this paper a production cost based maintenance scheme is proposed to minimize the production loss due to unscheduled equipment downtime events. Two maintenance plans, standby redundancy and vendor repair, are discussed and their impacts on the downtime cost are analyzed. The idea is to red... View full abstract»

    The traditional approach to handling functional dependence loops is based on Markov models, which are inefficient due to the well-known state space explosion problem. This paper proposes a new and efficient approach to handling functional dependence loops in the system reliability analysis. Based on the divide-and-conquer strategy, the approach transforms a system with functional dependence loops ... View full abstract»

    Based on some practical problems in industrial engineering, a species of two-unit parallel repairable system model is introduced in this paper. The prominent feature of the model is described as follows: if a repair time is sufficiently short (less than some threshold value) that does not affect the system operation, i.e. the effect could be ignored, the system can be considered as being operating...

    System reliability optimization involves the selection of components and a system architecture to maximize reliability. Most existing studies assume that the reliability values of the components are deterministic, and known with certainty. However, in practice the reliability of the component is just a point estimate, and therefore, there is some uncertainties associated with it. In this paper, we... View full abstract»

    Life cycle cost is the total cost incurred in the life cycle of a product, including design, development, production, operation, maintenance, support and disposal. Life cycle cost analysis can help engineers to identify equipment and process selection not on the initial purchase cost but rather on the total cost. A reasonable life cycle cost model can lead to a reliable design. In this paper, seve... View full abstract»
