Hori et al. constructed the Bayes-Fuzzy Estimation and demonstrated that system theory can be applied to the possibility of Markov processes, and that decision-making approaches can be applied to sequential Bayes estimation. In this paper, we focus on the Natural Flowing Case within reserved judgment. Here, the possibility of oblique (or principal) factor rotation is considered as a part of the tandem fuzzy system that follows step by step for sequential Bayes estimation. Ultimately, we achieve a significant result whereby the expected utility can be calculated automatically without the need to construct a utility function for reserved judgment. There, this utility in Re-Do can be calculated by the prior utility, and that utility in Re-set does not exist by our research in this paper. Finally, we elucidate the relationship between fuzzy system theory and fuzzy decision theory through an applied example of Bayes-Fuzzy theory. Fuzzy estimation can be applied to only normal making decision, but it is impossible to apply abnormal decision problem. Our Vague, specially Type 2 Vague can be applied to abnormal case, too.展开更多

According to the property of the items that affect "the green level" of the product, they can be divided into aspects, elements and factors. These make appreciable grades. Multi level fuzzy judgement can solve the appraisement problem that considers the influences of design, manufacture, use and recovery in all life cycle or multi life cycle of a product. In the judging process it not only deals with the action of all factors, but also continues to have all messages in grade judgement. The power coefficients stand out as the main items. An example is given to show the judgement process.展开更多

An upper bound of the WAMCJM＇s consistency is presented. Simultaneously, a compatibility index of judging the aggregating extent of group opinions is also introduced. The WAMCJM is of acceptable consistency and is proved provided the compatibilities of all judgement matrices given by experts are smaller than the threshold value of acceptable consistency. These conclusions are important to group decision making.展开更多

The fuzzy mathematical comprehensive judgement model has been adopted as the method of adjustment. Based on more than 300 water samples obtained from four typical profiles in the coastal region of Laizhou Gulf during the period from June 1993 to June 1995, we made a comprehensive judgement of seawater intrusion degree. The result shows that intrusion degree was becoming heavier from June 1993 to June 1994, but more steady and inactive in the high level of intrusion degree in the perennial severe intrusion zone from December 1994 to June 1995. Since entering the 1990s up to now, the process of seawater intrusion has translated from its peak developmental stage from the 1970s to the 1980s into a stage of equilibrium and slow development mainly because the intruded area expanded inland, precipitation increased at some extent recently and various measures of prevention and harness begin to show the effect.展开更多

Then, the corresponding convergent iterative algorithm is given and its convergence is proved. Finally, some main properties of the developed priority method, such as rank preservation under strong condition, etc., ate introduced. The theoretical analyses show that the MLSM can sufficiently reflect the preference information of the decision maker, and is easy to realize on a computer.展开更多

Clinical judgement remains a challenging cognitive process to articulate and assess. An integrative review of the literature conducted in 2016 identified 13 characteristics of clinical judgement. This paper reports the results of a 2-phase survey to obtain consensus whether these characteristics identified accurately represented nurses’ perception of clinical judgement. The 2-phase survey was administered via an online survey software tool. The survey in phase 1 sought Yes/No answers for nurse academics with recruitment via a hyperlink in an email to individuals identified from University websites, Google and published articles. In phase 2, the survey was modified to a Likert scale and recruitment occurred via online networks and was open to all nurses. The results identified that the characteristics accurately represented the nurse’s perception of clinical judgement. By articulating the characteristics, it allows clinical judgement to be easily described and can therefore be applied to both nursing research and education.展开更多

On the basis of analysis of fighter maneuvering performances, this paper proposes the parameters ωA,ωs, and SEP to measure the maneuvering performances. The linear weighted method, which is one of the basic methods of transforming several objects to a single object in mathematics programming, is used to determine the form of the correlating parameter expression. The focal point of this paper's work is to determine the weight coefficients of maneuvering performances in the expression. In order to solve this problem, the inverse problem of synthetic judgement in fuzzy mathematics is employed. The development of the equation of fuzzy relationship in this paper is based on the judgement data, which are gathered from many experts working in aeronautical field. Therefore, the expression of correlating parameter developed by this paper can be used in the design object at aircraft conceptual design stage and the judgement of synthetical measurement of the maneuverability of fighters.展开更多

Based on two interrelated experiments examining the processes and conditions of individual and scenario features influencing disgust and moral judgement about GMOs, this study aims to identify the different routes through which disgust influences moral judgement about GMOs in the physical and social dimensions. We found that the process of elicited state disgust influencing moral judgement on GMOs is regulated by pathogen disgust sensitivity and moral disgust sensitivity. The difference in opposition to GMOs brought by preferences for precepts implied in moral theories is evidently subject to the joint effect of the disgust elicitation type and emotion reappraisal(ER). This study clarifies the relationship between disgust for GMOs and moral judgement. It also confirms the effectiveness of ER in promoting the transition of moral judgement on GMOs from intuitive reaction to deliberation, thus offering benefits for science communicators targeting audiences who differ in their preferences for precepts implied in moral theories and trait disgust.展开更多
