As a basic dimension of physiological indicator, human mental workload is widely used in evaluating human performance and reliability. In this paper, the VACP method is applied to analyze the operator mental workload in LOCA with full power operating. Firstly, the operator task model is constructed. Secondly, on the basis of the VACP, the operators’ mental workload is determined. Lastly, based on importance analysis, the feature of those actions with different adjustment parameters β (1, 10 and 50) were identified. The result shows that the ‘Visual locating’ is the most important among those actions. The research had the application of dynamically evaluating human reliability come true, which can also provide an important basis for preventing human errors in NPP. It can also provide a reference for assessing operator reliability in other safety-critical domains.","PeriodicalId":168429,"journal":{"name":"2021 3rd International Conference on System Reliability and Safety Engineering (SRSE)","volume":"10 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":"117164420","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}

Hence, it is necessary to define an index that characterizes the random effectiveness of PM in the recurrent failure data analysis. Nevertheless, with purely the recurrent failure data, it is unreasonable to preset the index by a constant without knowing the specific physical mechanism of maintenance. In this paper, we propose a model based on the non-homogeneous Poisson process to account for both the inherent wear-out and the random effectiveness of PM for repairable systems. After each PM, the rate of occurrence of failures (ROCOF) of the system is multiplied by the index, which is modeled by a random variable following a gamma distribution. The Expectation-Maximum (EM) algorithm is then leveraged to estimate the parameters of the gamma distribution and the ROCOF. We apply the quasi-Monte Carlo method to approximate the multidimensional integration in the EM algorithm. The proposed model is validated by numerical simulations based on a real-world recurrent failure dataset of ambulances.","PeriodicalId":168429,"journal":{"name":"2021 3rd International Conference on System Reliability and Safety Engineering (SRSE)","volume":"24 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":"132227204","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}
