To estimate the reliability of a repairable system, the present statistics methods such like Probability distributions, Non-Parametric methods, Graphic solutions and Mixture of populations to figure out the reliability value are not suitable. In order to determine whether the prototype products or weapon system used in a demonstration test meet the specified reliability requirement, we here establish a suitable life data analysis procedure which based on Non-Homogeneous Poisson Process with Weibull Intensity Function and can estimate the reliability reasonably. During the research and development stages, we can also get some valuable information about parts life then to suggest a preventive maintenance. Furthermore, it will conduct us to make an optimum acceptance specification under a given producer''s and customer''s risks.

We develop models of non-Gaussion Kalman filter to apply in reliability. There are four themes in this paper: software reliability, accelerated life testing, fatigue-crack-growth model, and burn-in procedure. The reliability of computer software is a crucial measure about the quality of computer system. We have presented a Kalman filter to predict software failure time, which is a generalized JM model. Two important indexes for quality of software have been reached: the reliability function and the probability that the program is perfect. In practice, the system equation can be modified to satisfy the different situation. It can be applied to the imperfect debugging situation as well as in evolving programs. By examining a set of data on evolving program failures, the effect of evolving program model is amply proved. For estimating the reliability of long-life products, many techniques are used, such as the accelerated life testing (ALT), the degradation performance measuring, and the accelerated degradation testing (ADT). We propose a Kalman filter which is applied to the ALT and the degradation performance measuring. It assumes a Gamma type distribution for the observations, conditionally on unobserved state variables. A simple simulation study and an example for ALT are shown. The simulation result shows that when the observations are i.i.d., the inference about unobserved state parameters based on this model will be near to the true model; and the example shows that the predicted value of our model may better than m.l.e. in some cases. We can use this model to predict the future degradation performance. If failure is defined in terms of a specified level of degradation, a degradation model defines a particular time-to-failure distribution. The distribution of our model will be estimated by a fatigue-crack-growth data. In the fatigue-crack-growth example, there are some units censored. The estimate of time-to-failure distribution of our model based on the censored data is similar to the nonparametric estimate in full data, and the computing time is sooner than bootstrap method. Burn-in is a manufacturing operation that is intended to eliminate early failure. It becomes particularly meaningful when the distributions of the components'' lifetime have a decreasing failure rate in a neighborhood of the origin. In our problem, there are several components being tested at once, and a loss function, as the cost of burn-in which given by Clarotti and Spizzichino (1990) and Spizzichino (1991), will be introduced. We use a Bayesian steady forecasting model to describe the variation and uncertainty of the failure rate in testing period, and assume the burn-in is based on discrete time. We obtain an optimal strategy and simplify computing by an approximate method.

Non-Destructive Testing (NDT) plays an important role in the safety assessment of structures. Based on signal response of NDT detection, we can judge whether there are cracks or not in structures. However, The NDT result is influenced by many factors. Because of such uncertainty, the signal response data had better be analyzed with a linear regression model. The (Probability of Detection, ) curve as a function of crack length can be constructed from the data based on the model to reveal the ability of detection for a certain NDT apparatus. Since the thus evaluated is related to the probability distribution of the noise. A detailed statistical analysis of the noise is also provided in the present study. After testing of the probability distribution of noise, the assumed normal distribution is valid. But the variance of the probability distribution of noise from different crack length is not the same.

In the present study, a probabilistic fracture mechanics code PRAISE is used to evaluate the reliability of piping welds for the recirculation system of a nuclear power plant. The PRAISE code considers the initiation and/or growth of crack-like defects in the piping welds. The initiation analyses are based on the results of laboratory studies and field observations in austenitic piping materials operating under boiling water reactor conditions. The crack growth analysis is based on deterministic fracture mechanics principles, in which some of the inputs such as initial crack size are considered to be random variables, and the reliability for a given weld is evaluated by Monte Carlo simulation. The rusult provides the leak probability as a function of time for the studied boiling water reactor recirculation system. It can be used as a reference for the weld overlay of the recirculation system of a nuclear power plant.

Mechanics and reliability related issues of the multi-speed hub system of a bicycle are studied in the present thesis. First, failure mode and effect analysis (FMEA) is carried out to find possible failure modes of each component of the system, and identify the key component that is vulnerable to failure. Finite element analysis is then performed to find the maximum stress of the key component. The expected life and reliability of the component are evaluated based on a wear model. Finally, reliability allocation is performed to find an optimal selection of each component of the system in view of its individual cost and reliability. The result shows that an elastic shifter is the key component of the multi-speed hub system. Its maximum stress is 1.08 times of the material’s yield strength. If wear is considered, the reliability degradation of the shifter with respect to its usage cycle is found, and it has a mean life of 17,520 cycles. Finally, it is demonstrated that appropriate reliability can be allocated to each component of the hub system to obtain a minimum cost design while maintaining the required system reliability.

In this thesis, we employed the method of wafer level test with high stress voltage to accelerate the device degradation. Then, we utilized the accelerated factor to get the device lifetime that we operate under normal voltage. We found that this new method saves us 2.43 times of testing time and 3-day package time. This methodology brings us tremendous economic benefit. Moreover, in low temperature, the Hot Carrier Induce is extremely large, so if we move our testing environment to a low temperature system, the device will degrade must fast. We, then, employed this accelerated factor to get the device lifetime that we operate under normal voltage. Using this new technique, we can save 7.88 times of testing time and, therefore, we have much more economic benefit.

The fatigue crack growth of 2024-T351 aluminum alloy was studied in the present thesis. The scatter of the growth curves in addition to their mean growth trend is emphasized from the viewpoint of quality assurance of aeronautical structures. Probability and statistical theories were thus incorporated into the crack growth analysis that was well known to most engineers. The following working items have been carried out in particular in the present thesis. (1) Performed a considerable amount of fatigue crack growth tests made of 2024-T351 aluminum alloy. (2) Analyzed the test result according to the famous Paris law. (3) Analyzed the test data using probability and statistical theories. (4) Studied different fatigue reliability models and then proposed an appropriate model to explain the experimental result. The last item is, of course, the major work of the present thesis. It is found that a modified Yang/Manning fatigue reliability model can be adopted for the tested 2024-T351 aluminum alloy specimens. It can then be used as references for the integrity and reliability prediction of aeronautical structures made of 2024-T351 aluminum alloy.

The management of load-sharing in a system operation is critical work due to that an improper arrangement of loads will cause the reduction of system life and efficiency. The purpose of this thesis is to study the effects of loading adjustment on the system performance. To realize the operating situation of an assumed system, Monte Carlo method is included to simulate the system operation based reliability theory. Some applications are achieved by the simulation: (1) determine the priority sequence of components in system by combining the simulation with concept of short or open, (2) observe the system performance after improving the character of components with highly priority, (3) estimate the distribution of load probability varying with time and find out the characteristic of components in the system performance. In the study of priority analysis, after guaranteeing the most important component behavior, the next priority component will be changed, not as shown in the list of initial priority analysis.

ABSTRACT In this study, the reliability analysis was used to predict the damage state of existing reinforced concrete structures. The calculation of failure probability was on the basis of evaluating structures damage due to external factors and material properties. First, the existing reinforced concrete wharf located at harbor and subjected to chloride ions ingress for a long time was to predict the failure probability by using the combination of Poisson’s distribution and Fick’s second law in diffusion. Second, the reinforced concrete bridge pile underlaid amongst carbonation, chlorination, sulfate attack and loading failure was investigated to predict the structural system joint failure probability. The present results indicate as follows: (1) The combination of Poisson’s distribution and Fick’s second law in diffusion was to predict the failure probability of existing reinforced concrete wharf. It is not only used easily but also more conservative than that of the combination of linearly unbiased estimation and extreme value distribution. (2) The structural system joint failure probability was adopted to evaluate the failure probability of the existing reinforced concrete bridge pile subjected to carbonation, chlorination sulfate attack and load at the same time. Besides convenient calculation, this method is of feasibility and reliability. Keywords: corrosion damage, chloride ions, failure probability, system reliability

To take account of quality is the way that a business may keep the superiority edge of competition. Reliability is one of the most important quality factors. To proceed reliability analysis is the main topic to ensure a system'' or product''s lifetime quality. However, because the field data is always incomplete, it becomes a significant difficulty while proceeding the lifetime reliability analysis. The analysis results may also be inaccurate and useless. Corresponding to the difficulty, sometimes, reliability analyses will be generally based on a few complete data. Or, some censored data may also be combined with the insufficient data for analyzing. However, we may not know if any analysis result really presents the characteristic of system''s lifetime in such cases. Unfortunately, most of weapon systems are faced with such problems. In view of the fact, in this study, Monte Carlo simulation approach will first be applied to supply all “real” time to failures in different situations. The “real” data set of time to failures is assigned to a special kind of distribution and their parameter(s) for failure models. Second, the “whole” data set is simulated out with a Matlab program. Third, the whole data set is reduced in different situations, including being assigned to different amount of data and different censoring conditions. The reduced dataset is then compared and analyzed with the whole dataset by least square method and maximum likelihood method. The effects of different cases to the reduced dataset are analyzed. Methods for recovering the reduced dataset are studies. Judgments for methods are based on error bounds, mean difference and root mean square error. The results show that we may find out better ways to estimate more accurate and precise parameters for different failure modes in different situations. The better methods for recovered the censored data are also suggested. However, if the collected data are not enough, the recovered methods may not good enough, either.

As the electronic products toward the lighter, thinner, shorter and smaller ones, the size of the components inside the electronic packaging also reduced at the same time. In recent years, due to shortcomings of size reducing on the conventional 2D electronic packaging, the packaging industry and research units are engaged in the efforts of developing 3D stacking packaging. Consequently, through silicon via (TSV) technology become an effective and potential solution due to the vertical interconnections and multi-integration. In order to assess the reliability of 3D chip stacking structure, this study performed the temperature cycling test and temperature humidity test to qualify three types of TSV testkeys, including contact resistance（RC）, daisy chain total resistance（RT）and metal resistance（RM）, and to extract the life time and Weibull parameters for chip stacking structure with TSV. The results of this study may provide a useful reference of the reliability analysis for the industries.

ABSTRACT The fatigue test data of a batch of Gr/PEEK composite specimens are investigated in the present study. A probabilistic cumulative damage model proposed by Bogdanoff and Kozin in conjunction with some general statistic methods is employed to study the S-N relation, residual strength degradation, residual stiffness degradation, fatigue damage accumulation, and fatigue life of the composites. The strength life equal rank assumption (SLERA) is also adopted in the analysis. It is found that the proposed models can be used to describe the fatigue-related reliability reasonably well.

In study the reliability of electronic packages from mechanics point of view, the analytical result of stress and strain obtained from finite element analysis and fatigue life prediction based on a certain rule are all constant values. However, the real outcomes of package life obtained in laboratories appear to have probability distributions and are frequently plotted in Weibull probability papers. To investigate possible causes of this contradiction, analytical work is performed in the present study. The work includes, first, a finite element analysis based on the assumption that certain geometric parameters are random variables. The maximum strain of a certain type of flip-chip package subjected to thermal-cyclic loading is found, and the fatigue life of the package is determined base on a modified Coffin-Manson equation. Both quantities are random variables owing to the randomness of the geometric parameters. It is found that, among different geometric parameters, the size of the solder bump affects the fatigue life of the package the most. It may cause the fatigue life to have a coefficient of variation (c.o.v.) of 10.65% under the assumption that the solder diameter is a random variable between 0.27 mm and 0.33 mm. In the second phase of the present study, the modified Coffin-Manson equation is considered to have a certain random nature. This can be achieved by assuming certain parameters in the equation are random variables. Through mathematical derivation, it is shown that the predicted fatigue lives may have different mean values and different variations, and the difference may be tremendous under certain assumptions. It is concluded that both random geometric configuration and random life prediction rule may cause the fatigue life of the package to have distribution following certain probability density functions as those obtained from experiments.

In this article we mainly discuss the subject of safe reliability regarding the breakwater structures. We hope to analyze the reliability index of designed durable life of breakwaters in accordance of the reliability theory. First, we make a concise illustration of the relationship between the extreme-value probability and exceeding probability, then we explore the probability that both the storm surge level duration and tide level duration occur simultaneously, and set up the probability distribution of the maximum tide composed from storm surge level and tide level. Next, using the connection of wave height and the maximum tide we are going to build the probability distribution of wave height as well as the conditional probability distribution of wave height and the maximum tide. We apply them in the united exceeding probability with the time fact under consideration. Finally we use Rosenblatt Theory to convert the exceeding probability of wave height and tide into equivalent, independent standardize normal distribution of probability. The limiting state function of sliding discredit of breakwater body is built by Goda pressure formula to solve the resistance factor acted to breakwaters, substrate the load factor calculated from the dead weight of breakwaters times friction factor. In this article we select the breakwaters of Keelung harbor as the sample to proceed with the reliability analysis of body sliding of breakwaters. From the sample analysis we realize that the reliability index acquired by applying exceeding probability is far lower than the reliability index reached by traditional extreme-value probability. This conclusion could be an important reference for our harbor engineers making the evaluation of safety under plan, design and construction tasks.
