In this paper, complex network theory is introduced to model SSA data, and SSA state information is connected to the properties of the constructed network. Through analyzing the property quantities of the network, we can more effectively mine the characteristics of current data. A case study is conducted to demonstrate our method on a real traffic trace collected by an authority lab, and the test results verified that the property quantities of complex network can expose SSA messages about current state and future tendencies.","PeriodicalId":347031,"journal":{"name":"2016 11th International Conference on Reliability, Maintainability and Safety (ICRMS)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130811050","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}

Uncertainty analysis is a core problem in PRA, which must be addressed. There are several methods for analyzing uncertainty such as Monte Carlo simulation, interval analysis, probability bounds, the Dempster-Shafer theory of evidence, and fuzzy set theory. When the probability distributions of random input variables are specified, but the parameters are intervals, probability bounds analysis is an effective way to analyze the uncertainty of PRA. By constructing the probability boxes (p-boxes) of basic events, using the event chain model of PRA, uncertainty can be propagated from basic events to end states. The uncertainty analysis results verify the feasibility of probability bounds analysis of PRA in high microgravity science experiment system, and will provide a reference for the subsequent study of the quantitative risk assessment of space utilization payloads.","PeriodicalId":347031,"journal":{"name":"2016 11th International Conference on Reliability, Maintainability and Safety (ICRMS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133035646","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}

Then, based on the model, the test data from various environment conditions, various development phases, various structures and various objects were used to assess the reliability of shipborne weapon. The various test data is used synthetically to enlarge the sample size and increase the information for reliability assessment with the method.

As a kind of high-reliability and long-life product, film capacitor is widely used in communication, locomotive, and wind power generation, etc. Such a situation presents higher requirements for the life assessment method of film capacitors. Generally, we use the method of accelerated life testing for the evaluation of the product life of high-reliability and long-life. In order to assess the life of the film capacitor effectively and accurately, then further study the life situation of the system which film capacitor in, this paper is based on the cumulative failure model, through the analysis of the film capacitor failure conditions. What's more, this paper determines the lifetime distribution and acceleration model. Then optimizes accelerated life testing by using genetic algorithm and D-optimal.

In the traditional performance and reliability analysis, the performance and reliability are generally analyzed separately. However, when one of these cannot meet the requirements, researchers usually have to redesign the system. In order to solve these problems, the optimization of both the performance and reliability of a BLDC motor was proposed. This paper shows how the control system model of a BLDC motor was simulated using Saber, which was modified by the engineering data. A sensitivity analysis was used to determine the design dependent parameters and performance parameters of a BLDC motor, which could vary as a result of the manufacturing conditions, environmental temperature, and device degradation. The performance of a BLDC motor was analyzed using a Monte Carlo method, and the reliability of the BLDC motor was obtained using a statistical method according to the fault criterion. The dual response surfaces analysis method could optimize the performance and reliability simultaneously, providing a new method for the analysis of a motor.","PeriodicalId":347031,"journal":{"name":"2016 11th International Conference on Reliability, Maintainability and Safety (ICRMS)","volume":"271 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116188696","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 reactor protection system (RPS) in an HTR-PM is a safety-related system and is mainly in charge of monitoring safety-related parameters according to the reactor protection requirements. Thus, an RPS is very important to operations during the entire life cycle of an NPP. An RPS for an HTR-PM is completely designed and developed in China, which owns all intellectual property rights. Traditionally, the reliability of an RPS is evaluated based on a failure mode, effects, and criticality analysis (FMECA) and a fault tree analysis (FTA), which are static methods and cannot reflect the reliability of the system's dynamics. In this paper, we propose a dynamic reliability model for the RPS in an HTR-PM based on the Markov chain theory. Using this model, all states and their dynamic transition processes, especially the degradation process from a 2-out-of-4 structure to a 2-out-of-3 structure, are all determined. Moreover, based on this proposed model, an optimal surveillance test interval can be determined.","PeriodicalId":347031,"journal":{"name":"2016 11th International Conference on Reliability, Maintainability and Safety (ICRMS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128652287","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}

In the implementation of safety-critical software, there are many complex logics and testing requirements are relatively high. In structure-based testing, MC/DC coverage has a strong ability to detect errors compared to decision or condition coverage. However, it isn't enough to prove that the implementation is correct; there may be defects still lurking in the software. In this paper we classified the flaws in Boolean expressions into four types based on the software faults model and analyzed the MC/DC sensitivity to these flaws. We found that MC/DC is not sensitive to the relational condition boundary error. Additionally, we present a testing criteria called Enhanced-Condition-MC/DC (EC-MC/DC) as a method of improving MC/DC testing adequacy.
