Suich, Richard L. & Patterson, Richard L. & United States. Journal Article: Design description of the power supply subsystem for the TD1/TD2 satellites. Consider a 1-out-of-N standby system consisting of elements characterized by Weibull time-to-failure distributions with parameters η = and β = The per-time unit operation cost of each element is w = The standby mode dependent parameters d, W and v are presented in Table 1.
Standby mode 1 corresponds to cold standby; in this case the standby time deceleration factor is d(1) = 0 Cited by: 3. The U.S. Department of Energy's Office of Scientific and Technical Information.
Abstract. This chapter presents a numerical methodology to model and evaluate reliability, expected mission completion time, and expected total mission cost of 1-out-of-N: G standby sparing systems subject to periodic or non-periodic backup backups are performed to facilitate effective system recovery in the case of the occurrence of an online operating element : Gregory Levitin, Liudong Xing.
An iterative procedure is first suggested to evaluate system reliability and expected mission cost simultaneously. Based on the suggested evaluation algorithm, a genetic algorithm is then used as an optimization tool for solving the formulated optimal standby mode selection problem in 1-out-of-N: G warm standby : LevitinGregory, XingLiudong, PengSun, DaiYuanshun.
The performed analysis supported the design process and allowed to identify the major criticalities of the CubeSat design, as demonstrated in the extended case study included in the paper. The formalized method could be applied to design procedures for nano-satellites, as well as being expanded for research and development in a variety of space.

Computing systems are of growing importance because of their wide use in many areas including those in safety-critical systems. This book describes the basic models and approaches to the reliability analysis of such systems. An extensive review is provided and models are categorized into different types.
Some Markov models are extended to the analysis of some specific computing systems such as. Noté /5. Retrouvez Spacecraft expected cost analysis with k-out-of-n:G subsystems et des millions de livres en stock sur Achetez neuf ou d'occasionFormat: Broché.

The expected total number of failures denoted by M (t) is the summation of software failures and hardware failures as Example Consider the same example as in Examples and For this system, the expected numbers of software, hardware, and system failures are computed from the above equations.

Failure rate of the oxygen-mask deployment system is also 10–5/ hr Fatality probability for a hour flight is about 10–10 10 = 10–9 (10–9 or less is generally deemed acceptable) Probability of death in a car accident is 1/ per year (>10–7/ hr) Sep.

If the repair is a minimal repair (i.e., the failure rate of the product immediately after repair equals that right before failure), W (t0) can be written as 1 W (t0) = ln. A consecutive k-out-of-n:G system is one in which the n modules are linearly ordered, say, by indexing them from 1 to n, with the failure of any k consecutive modules causing system failure.
So, for example, such a system may not be able to function with exactly k working modules, unless these k modules happen to be consecutive.
