In the definition of the complex neutrosophic soft expert set (CNSES), parameters set is a classical set, and the parameters have the same degree of importance, which is considered as 1. This poses a limitation in modeling of some problems. This paper introduces the concept of fuzzy parameterized complex neutrosophic soft expert set (FP-CNSES) to handle this issue by assigning a degree of importance to each of the problem parameters. We further develop FP-CNSES by establishing the concept of weighted fuzzy parameterized complex neutrosophic soft expert set (WFP-CNSES) based on the idea that each expert has a relative weight. These new mathematical frameworks reduce the chance of unfairness in the decision making process. Some essential operations with their properties and relevant laws related to the notion of FP-CNSES are defined and verified. The notation of mapping on fuzzy parameterized complex neutrosophic soft expert classes is defined and some properties of fuzzy parameterized complex neutrosophic soft expert images and inverse images was investigated. FP-CNSES is used to put forth an algorithm on decision-making by converting it from complex state to real state and subsequently provided the detailed decision steps. Then, we provide the comparison of FP-CNSES to the current methods to show the ascendancy of our proposed method.

В статье рассматриваются разработки методов интеллектуальной поддержки процесса диагностики сахарного диабета, а также определение его типа. В последние годы количество людей, страдающих данным заболеванием, неуклонно растет, а без своевременной диагностики эта патология может нанести огромный вред организму человека. Сахарный диабет 1 типа опасен тем, что в основном возникает у людей молодого возраста. Оперативное обнаружение диабета, а также определение его типа, поможет не только избежать возможных осложнений, но и в некоторых случаях предотвратить смерть пациента. Информационные технологии все чаще используются в различных сферах деятельности для разработки новых или совершенствования существующих методов обработки данных, особенно это можно заметить в сфере медицины. В настоящее время врач самостоятельно ставит диагноз, основываясь на результатах различных анализов, однако, для ускорения процесса принятия решения, можно воспользоваться методами математического моделирования, а именно: моделями диагностики диабета на основе нечеткой логики. Для наибольшего удобства данный способ распознавания заболевания впоследствии можно реализовать в информационно-программное обеспечение, которое сможет еще больше увеличить эффективность и скорость распознавания патологии The article discusses the issues of the incidence of diabetes in the population, in particular, the definition of its type. In recent years, the number of people suffering from this disease has been steadily growing, and without timely diagnosis, this pathology can cause enormous harm to the human body. Prompt detection of diabetes, as well as determination of its type, will help not only avoid possible complications, but also in some cases prevent the death of the patient. Information technology is increasingly being used in various fields of activity to develop new or improve existing methods of data processing, especially in the field of medicine. Currently, the doctor independently makes a diagnosis based on the results of various analyzes, however, to speed up the decision-making process, you can use the methods of mathematical modeling, namely, models of diabetes diagnostics based on fuzzy logic. For the greatest convenience, this method of disease recognition can subsequently be implemented in information software, which can further increase the efficiency and speed of pathology recognition

Field development is a very important task in the petroleum industry. Decisions in this area may lead either to profitable success or to expensive failures, and usually involve several distinct areas in the scope of Petroleum Engineering and Science, such as Geology, Petreoleum Engineering, Offshore Engineering and Economics. Therefore, these subjects must be well understood by teams supporting the decision-making process. This work proposes a methodology to support managers in one stage of field development: the definition of the field production system. In order to determinate the production system to be installed in an oil field, attributes such as investment, profitability, safety, environmental preservation and technological experience must be considered. A decision-making team or agent must weight these attributes in order to achieve solutions accordingly to the company strategies and objectives. Combining a few mathematical tools to represent the process, the methodology proposed herein is an approach that considers not only the financial variables involved in a field decision process, but might include other aspects, or attributes, also important to guide a decision. To this end, the application of Multi-Attribute Analysis concepts is suggested. Also, to support the decision-making agent, the approach follows Utility Functions concepts in order to numerically represent the agent trend or inclination to each option. Considering that subjectivity and imprecision are naturally involved in the decision-making process, the approach incorporates Fuzzy Sets Theory concepts as a means of formalizing the computation of this uncertainty.

Student engagement in higher education has been studied from different theoretical perspectives and in different countries. Current issues include both concerns regarding students’ attitudes and ambivalence and, in addition, the definition of the concept of student engagement and how various pedagogical approaches may contribute to contrasting definitions. The present study thematically analyzed self-evaluations of 46 students attending two pedagogy courses of the University of Barcelona; both courses included lectures and discussions. Special attention was given to how participants described their engagement and related it to their learning, the teacher’s pedagogy, and the course content. Different forms of engagement emerged, both with the lecture and discussion sessions of the classes, that suggest some aspects of student engagement may (a) be invisible to the teacher and (b) follow an independent decision-making process that may favor passing over learning.

Abstract Definition of the problem The Shared Decision Making model is becoming increasingly popular also in the German-speaking context, but it only considers values of patients to be relevant for medical decisions. Nevertheless, studies show that the values of physicians are also influential in medical decisions. Moreover, physicians are often unaware of this influence, which makes it impossible to control it. Arguments The influence of both patients’ and physicians’ values is examined from an empirical and normative perspective. The review about the empirical data provides a necessary overview about the status quo, whereas I deduct rules for value-influenced behaviour in the decision making process in the normative approach. Therefore, different scenarios are taken into account to explore in which situations it is acceptable for physicians to let their values be part of the decision making process. The conscious use of values is only possible, when physicians are aware of their influence. To raise awareness, the best option would be to educate future physicians about it in their training. Therefore, this article provides a teaching concept for a unit that could be part of an ethics class for physicians in training. Furthermore, patient’s rights and responsibilities in the decision making process are discussed. Conclusion I conclude that it is necessary to take the influence of values (more) into account and include this knowledge into the training of physicians. Conclusively, recommendations for patients and physicians and their dealing with values in shared decision making processes are suggested.

Abstract In 2008 the Ainu were officially recognized as an indigenous people by the Japanese Government. The recognition arose from the 1997 court’s decision on the Nibutani Dam case which concluded, for the first time in Japanese history, that the Ainu people have the right to enjoy their own culture and that they fit the definition of indigenous people. The plaintiffs were Ainu landowners from the Nibutani Community who claimed the revocation of the expropriation decision. However, the Nibutani Dam was completed before the court’s decision, with the court acknowledging the completion as fait accompli on the grounds that the revocation of the expropriation decision would not be in the public’s interest. This article reveals the flawed legal system in the decision making process for public works as well as a brief history and some cultural background of the Ainu through those plaintiffs’ struggle for justice. Further, the illegitimacy of the Nibutani Dam project is discussed in light of publicness based on the complaint of those plaintiffs, and lastly, publicness of public works is explored in the context of studies on publicness in Japan.

Matrix Game with Payoffs RepresentedDue to the complexity of information or the inaccuracy of decision-makers’ cognition, it is difficult for experts to quantify the information accurately in the decision-making process. However, the integration of the fuzzy set and game theory provides a way to help decision makers solve the problem. This research aims to develop a methodology for solving matrix game with payoffs represented by triangular dual hesitant fuzzy numbers (TDHFNs). First, the definition of TDHFNs with their cut sets are presented. The inequality relations between two TDHFNs are also introduced. Second, the matrix game with payoffs represented by TDHFNs is investigated. Moreover, two TDHFNs programming models are transformed into two linear programming models to obtain the numerical solution of the proposed fuzzy matrix game. Furthermore, a case study is given to to illustrate the efficiency and applicability of the proposed methodology. Our results also demonstrate the advantage of the proposed concept of TDHFNs.

The article is aimed at studying and automating the stages of decision-making process for the development and implementation of health insurance products using the economic, mathematical, and simulation modeling. When analyzing the scientific works of scholars on the development of health insurance in Ukraine, the main stages of the decision-making process are allocated, the major of them are: the market need for an insurance product in the external environment; clear definition of the company’s tactical and strategic goals; examining the properties and characteristics of the insurance product; risk assessment and profitability of the insurance product. In the course of the study, the modeling of risk assessment, profitability of health insurance programs and analysis of the obtained results were carried out in detail. It is substantiated that a comprehensive analysis of the risk and profitability of health insurance programs will allow to form the necessary insurance reserves, to ensure the competitive position of an insurance company and to fulfill the targeted goals. If statistical information is available, any health insurance programs, including the COVID-19 insurance programs that require an assessment of pandemic risk, which requires special attention from both society and insurance, can be analyzed. It should be noted that modeling is a key element for assessing and managing pandemic risk. Prospects for further research in this direction are the expansion of the base of economic, mathematical and analytical models for assessing the risk of insurance portfolio and the inclusion in the simulation model of a wider range of factors of both the external and the internal environment.

In land-use planning, taking natural hazards into account cannot be based uniquely on the degree of danger, as shown on natural hazards maps. The level of risk brought in by the different types of human activity in the areas exposed to these hazards must also be taken into consideration. The communes in canton Vaud will soon have completed the realisation of all gravitational natural hazards maps according to catchment area. Consequently, a cantonal and intercommunal strategy for integral risk management must be put in place. The implementation of this strategy requires some prerequisites such as: legislation based on risks, a definition of protection objectives, the organisation of a decision-making process involving all parties concerned, and which will make possible a comprehensive evaluation of land-use related interests. These reflections should result in a change of attitude when faced with the risks linked to natural hazards, and hence land-use adapted to these risks respecting the principles of precaution, equity and proportionality.
