    The paper presents a method for obtaining an optimal reliability allocation of an n-stage series system. In each stage, redundant comnponents can be added (in parallel, stand-by, or k-out-of-n:G, etc.), or a more reliable component can be used in order to improve the system reliability. The solution is obtained by repeatedly using a more reliable candidate at each stage that has the greatest value... View full abstract»

    The usual constrained reliability optimization problem is extended to include determining the optimal level of component reliability and the number of redundancies in each stage. With cost, weight, and volume constraints, the problem is one in which the component reliability is a variable, and the optimal trade-off between adding components and improving individual component reliability is determi...

  • Minimum Cost Systems with Specified Reliability

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (226 KB)

    A method is presented for allocating reliability to each unit of a system with a view to minimizing the system cost. The practical utility of this method, as well as other methods, depends heavily on the availability of cost-reliability data for the 1 constituent units. Unfortunately, for most components such data are not readily available. There is a need for manufacturers and users to make these... View full abstract»

    This paper summarizes my recent work in analyzing preventive maintenance of the following kinds of repairable systems: 1-unit systems, 2-unit standby systems, and a system with unrepairable spare units. Some appropriate reliability measures of such systems are given, and optimum preventive maintenance policies which maximize or minimize these measures are derived under suitable conditions.

    The time dependence of the replacement rate of devices with lognormal failure distributions is studied. The relationship between the peak replacement rate and a, the standard deviation in the corresponding s-normal distribution, is obtained. The study assumes that each device represents a renewal process and the system of devices represents a superimposed renewal process. The peak replacement rate... View full abstract»

    This paper presents a policy for either repairing or replacing a system that has failed. The policy applies to systems whose mean residual life function is decreasing. An optimal policy is developed that minimizes the cost per unit time for repair and replacement. Results are shown graphically for a particular distribution of time to failure and are motivated in terms of an automobile replacement ... View full abstract»

    The steady-state availability of a repairable system with cold standbys and nonzero replacement time is maximized under constraints of total cost and total weight. Likewise the cost can be minimized under constraints of steady-state availability and total weight. A new, more efficient algorithm is used for the constrained optimization. The problem is formulated as a nonlinear integer programming p... View full abstract»

    A model for the s-expected cost of a development testing program is presented in this paper. The total cost function consists of two terms. The first term is proportional to the duration of the testing program; the second term is a loss function that assesses additional costs for failure to meet reliability goals during the testing program. The reliability growth model assumes that failures during... View full abstract»

    A mathematical model permits determining the duration of cost-optimized burn-in and evaluating the resultant saving for repairable electronics systems. Infant mortality failures occur according to a nonhomogeneous Poisson Process; repair actions restore the system to a bad-as-old condition. The s-expected costs associated with factory and field failures are traded-off with the costs of implementin... View full abstract»

    This paper describes an investigation of an optimization-with-constraints method, which uses a hypothetically acceptable level of risk as a constraint, for use in design of liquid metal fast breeder reactor (LMFBR) nuclear power generating stations. No attempt was made during the investigation to define the level of the acceptable risk. Major problems inherent in development of an optimization-wit... View full abstract»

    In the design of telephone switching systems, the sequence of reliability design functions can be stated as 1) the formation of reliability objectives, 2) the allocation of these objectives, and 3) the modeling to verify the reliability obtained. Optimization techniques can be used in both reliability allocation and reliability modeling. This paper discusses the formation of reliability objectives... View full abstract»

  • The Highest & Lowest Reliability Achievable with Redundancy

    Often system reliability can be enhanced through the use of redundancy. Redundancy may, however, have a detrimental effect on the statistical relationship of redundant elements. When the components in a redundant system have more than one failure-mode and when failures are s-dependent, it is difficult to assess the reliability of the system. The paper describes the ¿-transformation by which the h... View full abstract»
