In order to improve the capability to fit various failure data, a number of extended forms of Weibull distribution have been proposed. In this paper, we will focused on the four-parameter Weibull distribution. It is difficult to estimate the parameters of fourparameter Weibull model accurately under limited failure data, but we can treat the parameter as a random variable and use the gamma distribution as a prior distribution to get the imprecise ones. From the view of impreciseness and Bayesian theory, we proposed a novel imprecise reliability analytical method named the Four-parameter Weibull-Gamma model which used for incomplete life data. The upper and lower bounds of the cumulative density function, the reliability function and the hazard function can also be obtained. Aiming at two cases that the hazard function is monotonically increasing or a bathtub shape, the experiments demonstrate the fitting effect of the proposed model, and the modeling capability of components or systems for different hazard function. Furthermore, it also verifies the multi-parameter of the proposed model can increase the adjustable flexibility of the distribution.","PeriodicalId":119798,"journal":{"name":"2021 IEEE International Conference on Power Electronics, Computer Applications (ICPECA)","volume":"195 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121126383","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}

More and more barrier-free service resources such as new technologies, new products and new facilities are deployed in the terminal. In order to better improve the utilization rate and deployment rationality of barrier-free service resources and enhance the barrier-free service guarantee capability of civil aviation airports, it is necessary to evaluate the current use of barrier-free service resources and predict the future use frequency.

Autonomous vehicles are used in urban transportation to provide taxi service, which effectively reduces labor cost and realizes intelligent transportation systems. The vehicle system combined with 5G technology can quickly obtain traffic information, which provides a decision basis for the vehicle dispatching. Thus, it is necessary to develop an efficient way to distribute and allocate these vehicles to maximize the potential income for the system. This paper studies the vehicle dispatching based on the travel data from the 2016 New York City Green Taxi data and propose two dispatching methods. First, we consider the dispatching problem as a maximum weight value matching problem. Then a distance-based dispatching method is proposed with the goal of minimizing the waiting time of passengers by using the Kuhn and Munkres (KM) algorithm. Finally, we formulate the decision of vehicle dispatch with a Markov Decision Process (MDP) and introduce a Reinforcement Learning (RL)-based dispatching method, which combines RL algorithm and KM algorithm to solve the dispatching problem with the goal of maximizing long-term revenue of divers. In the experiment, KM algorithm is compared with the full permutation algorithm to prove the effectiveness of KM algorithm. The performance of the distance-based dispatching method and RL-based dispatching method are presented in a small-scale dispatching and a large-scale dispatching. Experiment results show that the total revenue of vehicles is improved by about 20% by using RL-based dispatching method, compared to dispatching method based on the distance. Thus, RL-based dispatching method is more effective in a dispatching platform. It could be used by future public autonomous vehicle companies to achieve the fulfill the need of maximizing the potential income for the system.","PeriodicalId":119798,"journal":{"name":"2021 IEEE International Conference on Power Electronics, Computer Applications (ICPECA)","volume":"133 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133354949","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}

Specifically, the distribution, shape and size of the pores were characterized, and the related histogram about the pore length distribution was also drew. According to CFRP pore statistical data, MATLAB was used to build a random pore model based on random process theory. The random medium was highly improved by using the extreme value search method. Thus, a random void model was deduced, well matched with our experiment results. During the establishment of the model, to make it closer to the actual pores, such important parameters as roughness factor, partition length and autocorrelation function were analyzed, and the statistical data of actual pores were used to optimize the parameters. Finally, a strict one-to-one correspondence was built between the stochastic model and the actual situation about pores. The model can provide theoretical support for our subsequent studies about explaining the effect of pores on ultrasonic testing and the scattering of ultrasonic waves in the pores during the testing process.","PeriodicalId":119798,"journal":{"name":"2021 IEEE International Conference on Power Electronics, Computer Applications (ICPECA)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116591079","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}

On the basis of numerical simulation analysis, an intelligent flexible manipulator system measurement and control platform is built. Numerical simulation and experimental results show that the proposed control strategy is feasible. This topic takes the multi-flexible robot arm as the research object, and uses the method of PID fuzzy control fusion to suppress the elastic vibration of the flexible robot arm. The vibration during the operation of the flexible arm reduces its positioning and operation accuracy, and the vibration suppression effect of the flexible arm is not the same in different control algorithms. To solve the problem that contact measurement affects the structure characteristics and the setting of PID control parameters is not ideal in the vibration active control system, the vibration control is carried out by using machine vision technology to measure the vibration of the structure and combined with the PID optimized by artificial fish swarm algorithm [1]. The main purpose of this paper is to improve the positioning and control accuracy of the flexible arm end and improve the operating efficiency of the system.","PeriodicalId":119798,"journal":{"name":"2021 IEEE International Conference on Power Electronics, Computer Applications (ICPECA)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117147363","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}
