The proposed method combines the principle of maximum relative entropy with approximate Bayesian computation and uses the Wasserstein distance to perform the approximate Bayesian computations. The key benefit of this approach is the capability to handle different types of information, such as point observed data and moment information. To verify the effectiveness of the proposed method, we apply it to a simple supported beam problem. The results are analyzed towards accuracy and the proposed method is compared to the classical Bayesian approach combined with maximum relative entropy.","PeriodicalId":168429,"journal":{"name":"2021 3rd International Conference on System Reliability and Safety Engineering (SRSE)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124925061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis shows that the kinetic energy at the moment when the armature is closed, the kinetic energy at the moment when the contacts are closed, the kinetic energy at the moment when the armature is released and the kinetic energy at the moment when the contacts are released are considered to be the key factors affecting noise. Afterwards, a finite element simulation model is established by taking a certain type of relay as an example, and on this basis, sampling points are selected to construct an approximate model. Finally, a multi-objective optimization method based on the efficient global optimization (EGO) algorithm is studied to optimize the noise reduction of this automotive relay, resulting in a significant reduction in noise while ensuring reliability.","PeriodicalId":168429,"journal":{"name":"2021 3rd International Conference on System Reliability and Safety Engineering (SRSE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130595408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach solved to lack of sufficient test data of storage degradation, which leads to failure of reliability evaluation in the initial phase of development of aerospace relays. Firstly, the Inverse Gaussian process is used to model degradation data which is strictly monotone. Secondly, based on the Bayesian theory, a posteriori estimation and a priori estimation of the model parameters are listed. Then, the process of using EM algorithm to solve hyperparameters is introduced. Finally, in combination with the actual case, the method of integrating simulation data and experimental data are used to conduct the Inverse Gaussian process degradation modeling and the reliability evaluation in combination with the Bayesian theory. The results show that the performance degradation modeling based on simulation data can effectively evaluate the reliability. And the introduction of a small amount of test data can will further improve the accuracy of reliability assessment. The proposed method could provide a new idea of reliability evaluation for products with high reliability and small samples.","PeriodicalId":168429,"journal":{"name":"2021 3rd International Conference on System Reliability and Safety Engineering (SRSE)","volume":"56 59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131023381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the impacts of real-life features of storage units and power generation units are not explored in current literature, this paper establishes a microgrid expansion planning model which takes into account real-world battery degradation mechanism. Reinforcement learning based simulation methods are applied to obtain the optimal microgrid expansion policy. Case studies are conducted to verify the effectiveness of the proposed model and investigate the impact of battery degradation. Furthermore, the influence of the unavailability of power plants during extreme power outages on optimal microgrid expansion planning is also explored.","PeriodicalId":168429,"journal":{"name":"2021 3rd International Conference on System Reliability and Safety Engineering (SRSE)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124606431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes several novel measures on component selection for PM. The relevant costs include the cost of system failure, the cost of repairing the failed component, and the PM cost.

The data for modelling are often heavily censored. In this case, it is a challenging issue to estimate the parameters. This paper proposes a new estimation method to address this issue. The proposed method estimates the shape parameter of a two-parameter life distribution through combining the concept of aging intensity with a semi-parametric smoothing TTT approach. The aging intensity of the Weibull distribution equals to its shape parameter; the smoothing TTT approach can be used to estimate the empirical aging intensity function, from which three representative values of the shape parameter are defined. Fixing each of them, the scale parameter is estimated using a singleparameter maximum likelihood method. In such a way, three distributions are fitted, from which a regression model is built to approximate the non-parametric estimates of the distribution function. The best model is selected based on the values of regression coefficients. Two examples are included to illustrate the appropriateness of the proposed approach.","PeriodicalId":168429,"journal":{"name":"2021 3rd International Conference on System Reliability and Safety Engineering (SRSE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124187090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
