fuzzy logic

Pursuing the goals of a government in the transnational sphere is planned and targeted through foreign policy, the most important of which can be considered as providing security. The current research aims to firstly examine the fragility of Central Asian states as the immediate environment of the Islamic Republic of Iran by using the fuzzy logic method and put the paths that exist in the fragility of Central Asian states as the basis for understanding the situation and by analyzing it, While recognizing the existing security threats in Central Asia, in the second step, he will develop a foreign policy appropriate to the current situation. For this purpose, the main questions of the research are: What is the state of fragility of Central Asian governments? How many paths of fragility are there in Central Asia? Considering the situation in Central Asia, what is the appropriate model of Iran's foreign policy? The result of examining the state of Central Asia in the fragility of governments indicates that all 5 existing governments have warnings of fragility and creating security problems, and two important variables in this situation are elites who oppose the government and vengeful and hostile groups. Referring to the theory of regional security, it seems that the prevention of multilateralism in foreign policy according to the status of each of the identified paths, in addition to providing regional security, will lead to playing a pivotal role for the Islamic Republic of Iran.

Fuzzy logic as a new tool in the analysis of political and social phenomena is a concept and approach that has recently entered political science. This approach has introduced other new concepts such as uncertainty, relativity, degree of truth, feasibility (vs. probability) etc. into these sciences. This article, which has been written with a descriptive analytical method, while explaining the concept and what is logical in the science of science, searching in this field to why and how to apply the steps and skills necessary to perform such an analysis in the field of political science with analysts of phenomena Political and social. The results show that the logic of social and political developments is not linear, and different variables always play a role in events, and since socio-political phenomena are voluntary human affairs and the uncertainty and involvement of many variables play a role in such affairs and phenomena; Fuzzy logic, despite its characteristics such as uncertainty, relativity and multiplicity of variables, is a suitable theoretical foundation for the analysis of political and social phenomena, which can explain these affairs and processes in terms of infrastructure on the one hand, and on the other hand, provide a logical framework for achieving It provided correct results in political analysis.

Security is the basic issue of all the governments of the world, whose external dimension is pursued by the foreign policy of the countries, and the security of the neighboring countries, which are the immediate environment of each country, are of special importance because the occurrence of security issues in one of the bordering countries increases the probability of the domino effect and leads to the creation of security problems in other neighboring countries or the region. The main question of the research originates from this issue and it is what is the state of fragility of the governments in Southwest Asia and what is the appropriate strategy for the security and promotion of Iran's position? To answer this question, the theory of regional security has been chosen as the theoretical basis and fuzzy logic as the research method, so that through examining the fragility of the governments of Southwest Asia, while recognizing the existing security threats, in the second step, the foreign policy appropriate to the existing situation will be developed. The result of the study of the state of fragility in Southwest Asia indicates that 13 of the 17 existing governments have warnings of fragility and creating security problems, and based on the theory of regional security, it seems that multilateralism in foreign policy, considering the status of each of the identified paths, will lead to playing a pivotal role for the Islamic Republic of Iran, in addition to providing regional security.

Population is one of the main causes of a country's prosperity. The current situation of the population and urbanization system in the country indicates a strong centralism and a type of urbanization that is the legacy of the urbanization and population policies of the period before the Islamic Revolution and which have continued since. Breaking down this flawed chain of urbanization and population distribution will require new policies and an innovative decision-making system based on sustainable development. In order to distribute the population within the geographical area available in the country, a solution, which can be carried out by the country's decision-making authorities, is to enforce land management planning. The purpose of this study is, to find a futuristic plan, which evaluates the optimal areas of population settlement so as to redistribute the population and lead to a reduction of centralism and the damage caused by it. In this research, a combined model of Fuzzy logic and network analysis has been used to locate the optimal areas of population settlement in Iran.

In this article, by adopting a descriptive-analytical method, using library tools, carrying out an interdisciplinary study and taking the general meaning of ethics into consideration, the terms "thought and belief", their relationship with the ethics of criminal justice and their application in some pillars, are first explained. Then, with an emphasis on a new reading of William Kingdon Clifford's theory of morality, as well as some moral concepts such as, rational responsibility and self-deception, the intellectual, epistemological foundations and beliefs of some elements of the criminal justice system is critiqued. Furthermore, the development and advancement of his moral logic in the application of this important matter in related issues is addressed.The explanation provided is, we believe that in decision-making bodies, and especially in important professions which deal with legislation and litigation, the holders of these rights are morally responsible to be prudent and criticize a belief based on a justifiable reason, and consequently observe the decision, seek the truth and make the right decision based on the facts. This is because they are morally responsible to think more carefully, find more realistic evidence, and to make more informed decisions and judgments in order to achieve a correct and right belief. Furthermore, they must ensure that there is a logical and rational relationship between their belief and reason. Fuzzy Logic was the criterion and logic employed in order to evaluate the ethics of belief.

This article seeks to answer the question: what are the components of resistance economy in Iran Khodro Industry in the political and economic thought of the Supreme Leader and the Holy Quran with fuzzy Delphi technique? In this study, Delphi fuzzy technique as one technique for scientific analysis has been used to reach consensus among panel expert members in finding the components and dimensions of resistance economy of IRI's Automotive Industry. According to the research question, in the thought of resistance economy, the Supreme Leader of the Revolution mentioned 10 main components in resistance economy as: jihadi management, leading economy, meeting customer needs, endogenous economy, strengthening manpower and knowledge and technology, being extroverted, opportune-making, empowering Employees, Economic Jihad, and Cultural Policy-making. The results showed that, given the above components, endogenous economics was recognized as the most important dimension with the components: independence, self-sufficiency, and actualization of domestic capacities.

The price movement strategy is more about finding return levels and ranges. These ranges can be the return of trend correction or market return due to the end of the trend or the return of the market from the floor or ceiling of the oscillation range. , is. In terms of its objectives, the present study is an applied research, which means that it seeks to gain the necessary knowledge to determine the means by which stakeholders need to consider very important points, including identifying turning points in purchasing decisions and Sales are crucial, get rid of them. Also, since we seek to find relationships between variables in order to identify return points and evaluate the impact of their changes on the overall result, this study in terms of how to do it; It will be a causal or experimental research. Also in terms of data type, it will be a research with little data. Also, from the point of view of implementation time, it is a cross-sectional research followed by futurism. In this research, fuzzy logic and genetic algorithm were used to provide a method for identifying return points in financial markets. For this purpose, a mamdani fuzzy system has been used. . After implementing the proposed structure, the evaluation of the optimized membership functions was performed in order to ensure that these functions are in line with the desired research (determination of return points).

Few decades have passed since the birth of regional studies as sub-field of political science and international relations¡ but the dominance of international relations approaches on scientific literature and research method of this scientific field in inevitable. The evolution procedure of regional studies field showed that doing research in this field may require research in history¡ political science¡ sociology¡ economics¡ geopolitics and many of other scientific tendencies that can be referred based on the case. This subject shows the difficulty of research in regional studies field. This paper is determined to introduce the Fuzzy cognitive maps as a method with capability of application in regional studies field¡ so this method can meet the researcher’s needs in the field of study of subjects without any background before¡ or entitled as a vague phenomenon. The advantage of this method firstly is the ability of recognizing the elements of vague phenomenon and helping to understanding the relations among them and secondly the derivation of the agreed point from various views about that phenomenon.

This paper argues for a broader emphasis on sustainable security and smart power، and for examining both opportunities as well as threats to security. Sustainable security is a new concept in the security studies. Deep attention to all possible threats against human life is necessary for continuation of security in a sustainable and dynamic base. This aim can be achieved in a highest level by merging the negative and positive discourses of security. In the negative discourse security is required having hard power and force to encounter with deferent kinds of threat. In other words، the authority of a security system depends on it’s ability to confronting with hard threats. In the other hand according to positive discourse، soft power is necessary for eliminating the internal defects and encouraging the system’s values. The main question of this research is: what is the connection between smart power and sustainable security? Accordingly، our hypothesis is: there is a direct connection between smart power and sustainability of security. In fact to attain the sustainable security، soft power and hard power should be merged and create the smart power. This research recommends emphatically that systematic and network attitude، theoretically and practically، is necessary for designing and putting into effect the sustainable security. In this way we are going to use fuzzy logic and systematic attitude in a new approach called fuzzy-systematic. The results of this research are also confirming this point that using the fuzzy systems can enhance the possibility of gaining the sustainable security through smart power. The information of this article gathered by using the library and internet sources and we analyzed our data through descriptive-analytic method.

Whereas one group of researchers think of Islam as inherently political in their investigating the proportion of Islam to politics, the other group thinks of the political reading of Islam as a new phenomenon that has resulted from the contact between Islamic world and the West and modernity. Either has presented many proofs and documents, and so far none of them has succeeded in convincing the other. However, based on the fuzzy logic, which shows that any proposition can be either true or false, it can be said that while facing politics and power, Islam has invariably taken a position given its own position, and in fact the position has been with particular political proportion. On the other hand, although the political Islam has been conceptually unprecedented, it is not disproportionate to Islam. More importantly, by using a fuzzy set, it can be seen that scholars and religious authorities have always been political to some extent during the Occultation, and the avoidance of politics under the title of dissimulation, stopping the enforcement of religious punishments during the Occultation according to some religious scholars’ jurisprudential opinion, or the establishment of the Islamic Government with jurists’ guardianship and their governance over all pillars of power, all constitute the zero and one of our fuzzy set, which have the least membership in the fuzzy set, and most scholars, authorities and Shiite thoughts fall within zero and one.

Relation between theory and fact is one of the most important and attractive issues of social science. Almost، all of us using theory in our scholarly endeavors without thinking deeply about the relation between theory and fact. Considering the necessity of a simultaneous theoretical and factual understanding of social phenomena، this article explains “theory-fact” relation according to the three main methodologies of science (Phenomenology، Interpretationism، Instrumentalism) and at the end will offer an alternative approach to this issue area based on the fuzzy logic.
