The paper puts a question about age-related features of searching strategies of elderly people. While searching the informants, as a rule, recollect the only word （a noun, including their own name）, they do not choose the most suitable nominations from the available options. They often refuse to search and realize an alternative speech strategy.展开更多

Hesitant fuzzy sets are a powerful tool to treat this case. The present paper focuses on investigating the clustering technique for hesitant fuzzy sets based on the K-means clustering algorithm which takes the results of hierarchical clustering as the initial clusters. Finally, two examples demonstrate the validity of our algorithm.展开更多

First, double hesitant linguistic elements are defined as representing the uncertain assessment information in the process of group decision making accurately and comprehensively, and the double hesitant linguistic weighted averaging operator is developed based on the defined operational laws for double hesitant linguistic elements. Then, double hesitant linguistic preference relations are defined and a means to objectively determine the weights of decision organizations is put forward using the standard deviation of scores of preferences provided by the individual decision organization for altematives. Finally the correlation coefficient between the scores of preferences and the scores of preferences are provided by the other decision organizations. Accordingly, a group decision method based on double hesitant linguistic preference relations is proposed, and a practical example of the Jiudianxia reservoir operation alternative selection is used to illustrate the practicability and validity of the method. Finally, the proposed method is compared with the existing methods. Comparative results show that the proposed method can deal with the double hesitant linguistic preference information directly, does not need any information transformation, and can thus reduce the loss of original decision information.展开更多

Cancer patient, whose immunity is often compromised, faces a huge challenge.Currently, some COVID-19 vaccines are being developed and applied on general population;however,whether cancer patients should take COVID-19 vaccine remains unknown. Our study aimed to explore the knowledge, attitude, acceptance, and predictors of intention to receive the COVID-19 vaccine among cancer patients in Eastern China.Methods: A cross-sectional study was conducted in Eastern China from June 17 th to September 3 rd, 2021.Patients were selected using a convenience sampling method. A self-report questionnaire was developed to assess knowledge about the COVID-19 vaccine, attitude towards the vaccine and acceptance of the vaccine;following a review of similar studies previously published in the scientific literature, multivariate logistic regression analysis was used to determine the predictors associated with COVID-19 vaccine acceptance.Results: A total of 2158 cancer patients were enrolled in this study. The rate of vaccine hesitancy was 24.05%(519/2158);further, among the participants of vaccine acceptance, 767 had taken COVID-19 vaccine(35.54%), and 872 were willing to get vaccinated(40.01%). A total of 24 variables including demographic characteristics, clinical status of cancer, impact of COVID-19 pandemic on study participants,patients’ knowledge about the COVID-19 vaccine, and attitude towards the vaccine, had significant differences between the ‘‘vaccine hesitancy" population and ‘‘vaccine acceptance" population.Multivariate logistic regression analysis indicated that parameters including alcohol consumption(odds ratio [OR] = 1.849;95% confidence interval [CI]: 1.375–2.488;P-reference [P-Ref] < 0.001 vs nondrinkers), income impacted by COVID-19 pandemic(OR = 1.930, 2.037 and 2.688 for mild, moderate,and severe impact, respectively;all P-Ref < 0.01 vs no impact), knowledge of how the vaccine was developed(OR = 1.616;95% CI: 1.126–2.318;P-Ref = 0.009 vs unknown), believing in the safety of the vaccine(OR = 1.502;95% CI: 1.024–2.203;P-Ref = 0.038 vs denying the safety of vaccine), willingness to pay for the vaccine(OR = 3.042;95% CI: 2.376–3.894;P-Ref < 0.001 vs unwilling), and willingness to recommend families and friends to get vaccinated(OR = 2.744;95% CI: 1.759–4.280;P-Ref < 0.001 vs do not recommend) were contributors to vaccine acceptance. While such as being retired(OR = 0.586;95% CI: 0.438–0.784;P-Ref < 0.001 vs unemployed), undergoing multiple therapies of cancer(OR = 0.408;95% CI: 0.221–0.753;P-Ref = 0.004 vs no ongoing treatment), and worrying that the vaccine might deteriorate the prognosis of cancer(OR = 0.393;95% CI: 0.307–0.504;P-Ref < 0.001 vs might not) were contributors to vaccine hesitancy.Conclusion: This study provided preliminary estimates of the rates of vaccine acceptance and vaccine hesitancy among cancer patients in Eastern China. The intention to receive the COVID-19 vaccine was impacted by factors such as patient occupation, alcohol consumption, and some parts of knowledge about and attitude towards COVID-19 vaccine. It is recommended to develop individualized vaccination plans that meet the healthcare needs of cancer patients.展开更多

This kind of uncertainty may increase the coil voltage difference （CVD） caused by hesitate phenomenon in the pick up process of AEMR. Taking a certain type of AEMR for example, the CVD problem in the actual producing process has been studied in this paper. The primary cause of this issue, two-steps of armature motion （namely hesitate phenomenon） in the pick up process, has been found by analyzing the matching characteristics of electromagnetic and mechanical torques of AEMR. Through the optimization of the matching characteristics, the two-steps of armature motion problem is solved by robust design of the return reed which is a key part of AEMR. The validity of this research has been proved by the comparison of characteristics of AMER before and after the optimization.展开更多

However, in the assessment process, expert’s judgement will directly affect the assessment accuracy. In addition,there are many criteria involved in the missile design alternatives. Some criteria with poor performance may be compensated by other criteria with excellent performance, and then it is impossible to find the truly optimal alternative. Aimed at solving these problems, this paper proposes a synthetical assessment process based on fuzzy hesitant linguistic term set and the Gained and Lost Dominance Score(GLDS) method. In order to improve the assessment accuracy of experts and solve the problem that experts generate different opinions, combined with the advantages of fuzzy hesitant sets and linguistic term sets, the double hierarchy hesitant fuzzy linguistic term sets are used in this paper to improve the accuracy of expert’s judgement. In order to effectively combine expert’s experience with the data of criteria, the evidence theory and entropy weight method are used to transfer the expert’s judgement to the weight. In order to avoid selecting defective alternative of missile design, the GLDS is used to fuse expert information and criteria information. Sensitivity analysis shows that the assessment process has sensitivity to some extent. However, when the fluctuation of expert’s assessment makes the fluctuation of θ in the range of-5% to 5%, the impact on the results is not quite conspicuous. The analysis of calculation result and comparative analysis show that the assessment process proposed in this paper is accurate enough, has great advantage in selecting the current and potential optimal alternative of missile design, and avoids the alternatives with low criteria performance that cannot be compensated by other criteria being selected.展开更多

文摘The hesitant fuzzy set(HFS) is an important tool to deal with uncertain and vague information.In equipment system portfolio selection, the index attribute of the equipment system may not be expressed by precise data;it is usually described by qualitative information and expressed as multiple possible values.We propose a method of equipment system portfolio selection under hesitant fuzzy environment.The hesitant fuzzy element(HFE) is used to describe the index and attribute values of the equipment system.The hesitation degree of HFEs measures the uncertainty of the criterion data of the equipment system.The hesitant fuzzy grey relational analysis(GRA) method is used to evaluate the score of the equipment system, and the improved HFE distance measure is used to fully consider the influence of hesitation degree on the grey correlation degree.Based on the score and hesitation degree of the equipment system,two portfolio selection models of the equipment system and an equipment system portfolio selection case is given to illustrate the application process and effectiveness of the method.
文摘The Hamlet’s scruple is dealt with, which has been disputed for a long time. Hamlet’s hesitation shows kindness and conscience of the human nature. Hamlet is not the individual tragedy of Hamlet, but the tragedy of the society owing to Hamlet’s uncle’s sins, which indicates the philosophy theory that if natural law is violated, it will bring about unexpected disaster.

文摘To solve the problem that the existing situation awareness research focuses on multi-sensor data fusion,but the expert knowledge is not fully utilized,a heterogeneous informa-tion fusion recognition method based on belief rule structure is proposed.By defining the continuous probabilistic hesitation fuzzy linguistic term sets(CPHFLTS)and establishing CPHFLTS distance measure,the belief rule base of the relationship between feature space and category space is constructed through information integration,and the evidence reasoning of the input samples is carried out.The experimental results show that the proposed method can make full use of sensor data and expert knowledge for recognition.Compared with the other methods,the proposed method has a higher correct recognition rate under different noise levels.
文摘The author studies the markers of searching for a word in spontaneous oral speech of Russian-speaking elderly women. The paper puts a question about age-related features of searching strategies of elderly people. While searching the informants, as a rule, recollect the only word （a noun, including their own name）, they do not choose the most suitable nominations from the available options. They often refuse to search and realize an alternative speech strategy.

文摘Due to the limitation and hesitation in one＇s knowledge, the membership degree of an element to a given set usually has a few different values, in which the conventional fuzzy sets are invalid. Hesitant fuzzy sets are a powerful tool to treat this case. The present paper focuses on investigating the clustering technique for hesitant fuzzy sets based on the K-means clustering algorithm which takes the results of hierarchical clustering as the initial clusters. Finally, two examples demonstrate the validity of our algorithm.

文摘A simple decision method is proposed to solve the group decision making problems in which the weights of decision organizations are unknown and the preferences for alternatives are provided by double hesitant linguistic preference relations. First, double hesitant linguistic elements are defined as representing the uncertain assessment information in the process of group decision making accurately and comprehensively, and the double hesitant linguistic weighted averaging operator is developed based on the defined operational laws for double hesitant linguistic elements. Then, double hesitant linguistic preference relations are defined and a means to objectively determine the weights of decision organizations is put forward using the standard deviation of scores of preferences provided by the individual decision organization for altematives. Finally the correlation coefficient between the scores of preferences and the scores of preferences are provided by the other decision organizations. Accordingly, a group decision method based on double hesitant linguistic preference relations is proposed, and a practical example of the Jiudianxia reservoir operation alternative selection is used to illustrate the practicability and validity of the method. Finally, the proposed method is compared with the existing methods. Comparative results show that the proposed method can deal with the double hesitant linguistic preference information directly, does not need any information transformation, and can thus reduce the loss of original decision information.

文摘Objective: The coronavirus disease 2019(COVID-19) pandemic has had a serious impact on health all over the world. Cancer patient, whose immunity is often compromised, faces a huge challenge.Currently, some COVID-19 vaccines are being developed and applied on general population;however,whether cancer patients should take COVID-19 vaccine remains unknown. Our study aimed to explore the knowledge, attitude, acceptance, and predictors of intention to receive the COVID-19 vaccine among cancer patients in Eastern China.Methods: A cross-sectional study was conducted in Eastern China from June 17 th to September 3 rd, 2021.Patients were selected using a convenience sampling method. A self-report questionnaire was developed to assess knowledge about the COVID-19 vaccine, attitude towards the vaccine and acceptance of the vaccine;following a review of similar studies previously published in the scientific literature, multivariate logistic regression analysis was used to determine the predictors associated with COVID-19 vaccine acceptance.Results: A total of 2158 cancer patients were enrolled in this study. The rate of vaccine hesitancy was 24.05%(519/2158);further, among the participants of vaccine acceptance, 767 had taken COVID-19 vaccine(35.54%), and 872 were willing to get vaccinated(40.01%). A total of 24 variables including demographic characteristics, clinical status of cancer, impact of COVID-19 pandemic on study participants,patients’ knowledge about the COVID-19 vaccine, and attitude towards the vaccine, had significant differences between the ‘‘vaccine hesitancy" population and ‘‘vaccine acceptance" population.Multivariate logistic regression analysis indicated that parameters including alcohol consumption(odds ratio [OR] = 1.849;95% confidence interval [CI]: 1.375–2.488;P-reference [P-Ref] < 0.001 vs nondrinkers), income impacted by COVID-19 pandemic(OR = 1.930, 2.037 and 2.688 for mild, moderate,and severe impact, respectively;all P-Ref < 0.01 vs no impact), knowledge of how the vaccine was developed(OR = 1.616;95% CI: 1.126–2.318;P-Ref = 0.009 vs unknown), believing in the safety of the vaccine(OR = 1.502;95% CI: 1.024–2.203;P-Ref = 0.038 vs denying the safety of vaccine), willingness to pay for the vaccine(OR = 3.042;95% CI: 2.376–3.894;P-Ref < 0.001 vs unwilling), and willingness to recommend families and friends to get vaccinated(OR = 2.744;95% CI: 1.759–4.280;P-Ref < 0.001 vs do not recommend) were contributors to vaccine acceptance. While such as being retired(OR = 0.586;95% CI: 0.438–0.784;P-Ref < 0.001 vs unemployed), undergoing multiple therapies of cancer(OR = 0.408;95% CI: 0.221–0.753;P-Ref = 0.004 vs no ongoing treatment), and worrying that the vaccine might deteriorate the prognosis of cancer(OR = 0.393;95% CI: 0.307–0.504;P-Ref < 0.001 vs might not) were contributors to vaccine hesitancy.Conclusion: This study provided preliminary estimates of the rates of vaccine acceptance and vaccine hesitancy among cancer patients in Eastern China. The intention to receive the COVID-19 vaccine was impacted by factors such as patient occupation, alcohol consumption, and some parts of knowledge about and attitude towards COVID-19 vaccine. It is recommended to develop individualized vaccination plans that meet the healthcare needs of cancer patients.

文摘As for aerospace electromagnetic relay （AEMR） which is of small batches and having difficulty in automatic production, the uncertainty phenomenon is remarkable due to excessive manual work involved in the assembly and adjustment processes. This kind of uncertainty may increase the coil voltage difference （CVD） caused by hesitate phenomenon in the pick up process of AEMR. Taking a certain type of AEMR for example, the CVD problem in the actual producing process has been studied in this paper. The primary cause of this issue, two-steps of armature motion （namely hesitate phenomenon） in the pick up process, has been found by analyzing the matching characteristics of electromagnetic and mechanical torques of AEMR. Through the optimization of the matching characteristics, the two-steps of armature motion problem is solved by robust design of the return reed which is a key part of AEMR. The validity of this research has been proved by the comparison of characteristics of AMER before and after the optimization.

文摘Three-way decision(T-WD)theory is about thinking,problem solving,and computing in threes.Behavioral decision making(BDM)focuses on effective,cognitive,and social processes employed by humans for choosing the optimal object,of which prospect theory and regret theory are two widely used tools.The hesitant fuzzy set(HFS)captures a series of uncertainties when it is difficult to specify precise fuzzy membership grades.Guided by the principles of three-way decisions as thinking in threes and integrating these three topics together,this paper reviews and examines advances in three-way behavioral decision making(TW-BDM)with hesitant fuzzy information systems(HFIS)from the perspective of the past,present,and future.First,we provide a brief historical account of the three topics and present basic formulations.Second,we summarize the latest development trends and examine a number of basic issues,such as one-sidedness of reference points and subjective randomness for result values,and then report the results of a comparative analysis of existing methods.Finally,we point out key challenges and future research directions.
文摘Warhead power assessment of the anti-ship missile plays a vital role in determining the optimal design of missile, thus having important strategic research significance. However, in the assessment process, expert’s judgement will directly affect the assessment accuracy. In addition,there are many criteria involved in the missile design alternatives. Some criteria with poor performance may be compensated by other criteria with excellent performance, and then it is impossible to find the truly optimal alternative. Aimed at solving these problems, this paper proposes a synthetical assessment process based on fuzzy hesitant linguistic term set and the Gained and Lost Dominance Score(GLDS) method. In order to improve the assessment accuracy of experts and solve the problem that experts generate different opinions, combined with the advantages of fuzzy hesitant sets and linguistic term sets, the double hierarchy hesitant fuzzy linguistic term sets are used in this paper to improve the accuracy of expert’s judgement. In order to effectively combine expert’s experience with the data of criteria, the evidence theory and entropy weight method are used to transfer the expert’s judgement to the weight. In order to avoid selecting defective alternative of missile design, the GLDS is used to fuse expert information and criteria information. Sensitivity analysis shows that the assessment process has sensitivity to some extent. However, when the fluctuation of expert’s assessment makes the fluctuation of θ in the range of-5% to 5%, the impact on the results is not quite conspicuous. The analysis of calculation result and comparative analysis show that the assessment process proposed in this paper is accurate enough, has great advantage in selecting the current and potential optimal alternative of missile design, and avoids the alternatives with low criteria performance that cannot be compensated by other criteria being selected.
