In this paper, we presented a simulation based model to analysis the reliability of phased-mission system (PMS) with repairable components. Many researches on the repairable PMS supposed that failed components would be repairable only when the system is in a good state. It is different here that failed components can be repaired no matter what state is the system in. The mission successes if and only if the sum of Phase Work Time and Phase Maintenance Time is less than the limited time. The simulation model is an efficient method when the system becomes more and more complex. It can also solve the problem when the components' life and maintenance time have different distributions from exponential.

To monitor the initial failure of cooling fan's rolling bearing, this paper reviews the theory of autoregressive (AR) model and the minimum entropy deconvolution (MED) filtering technique. The AR method can remove the deterministic components of the original signal, and the MED filter could reduce the effect of the transmission path. These two filtering techniques were combined in this paper to pre-process the rolling bearing's vibration signal, and then the envelope spectrum of the residual signal was analyzed. The method leads to efficient filtering result.

To study mission reliability allocation of the tracking, telemetry and command (TT&C) system, which is difficult to describe with a precise mathematical model and time-consumed to compute, a radial basis function neural network (RBFNN) modeling method with adaptive hybrid learning algorithm (AHL) is proposed. Principal component analysis (PCA) is used to determine the initial number of hidden units. Advanced gradient learning algorithm (AGL) to compute gradient information of network parameters is improved to accelerate convergence. Finally, realization details are provided, and simulation results show the effectiveness of the proposed method.

Fault tree analysis (FTA) is a top-down approach for failure analysis, starting with a potential undesirable event called a TOP event, and then determining all the ways it can happen. FTA is the most commonly used technique for causal analysis in risk and reliability studies. Mask stage an important part of lithography. In this paper, Fault Tree of the mask stage is built with “Mask stage doesn't work” as the top event. Quantitative assessment and qualitative analysis based on Fuzzy Logic are carried out. And the importance of bottom events is calculated.

System reliability becomes an increasing concern. The separate generation of hardware and software reliability test data cannot satisfy the demands of system reliability study. This paper introduces an approach to develop the system usage profile, which describes the system how to be used from the analysis of both hardware and software. By establishing the different scenarios of hardware and software, the system scenarios can be obtained. The development of system usage profile is illustrated with an example of air-conditioner.

Evaluating probabilistic constraints plays a very important role in the reliability-based design optimization (RBDO). Traditional Monte Carlo simulation-based approach can provide a high accuracy but with low efficiency. In this paper, a subset simulation-based reliability analysis approach is provided to address the efficiency problem. The method is also compared with the typical MPP-based method.
