optimization

The aim of the present study is to optimize the behavioral indicators of entrepreneurial performance in technology-based startups. The research method of this study is a mixture (qualitative-quantitative) of the meta-synthesis method in the qualitative part and the decision tree and genetic algorithm in the quantitative part. For this purpose, the meta-synthesis method has been used to examine and identify the dimensions and influential factors, in which regard the research population is 164 valid scientific articles published between 2013 and 2023, after specialized filtering and quality control of the texts, 38 articles were selected for analysis and coding. Next, the meta-heuristic algorithm was used to optimize the identified indicators. For this purpose, in the meta-heuristic algorithm section, the genetic algorithm was used for its optimal modeling because it was the best method for optimizing this research according to experts. The findings showed that in the qualitative section, we obtained 97 open codes and 18 closed codes, which were categorized into four categories: entrepreneurial structural factors, entrepreneurial behavioral factors, entrepreneurial capital factors, and entrepreneurial external factors. In the quantitative section, for the indicators, it shows that the indicators of government programs, entrepreneurship education in elementary schools, entrepreneurship education after school, and finally business and professional infrastructure have the greatest impact on the classification of countries, respectively, and to improve the status of entrepreneurs and the ranking of countries, special focus should be placed on these four areas

The public policy cycle, which includes the stages of problem determination, policy formulation, policy implementation, and evaluation and revision, is examined as a structured process to guide and improve public policies. The purpose of the policy cycle is to simplify and organize the policy-making process in the minds of decision-makers and decision-makers. With the help of this cycle, different stages of policy making can be divided into sections so that the analysis of the stages is possible separately. Of course, the stages of the political cycle have been operationalized in different ways over time and according to the type of political system. Also, despite having various advantages, the policy-making cycle has been criticized both empirically and scientifically due to the emphasis on different and discrete stages in the policy-making process. The present article, which was written using the descriptive-analytical method, tries to provide a complete, clear and optimized model of the public policy cycle in the implementation of the desired policy process while criticizing the existing models. This new cycle has twelve steps.

Gasoline is considered one of the most important and strategic products that is produced in oil refineries and among the consumption of energy products, motor gasoline consumption in Iran alone has a share of about 43%, so the most attention to effective management is required. The trend of increasing gasoline consumption in 1401 sounded the alarm to enter the channel of gasoline shortage and forced to import this product and may lead to the loss of export opportunities. Also, population growth puts considerable strain on available resources and significantly affects climate change. Besides, the oil, gas, and petrochemical industries are one of the most polluting industries in the world. Therefore, in recent years, the effective implementation of sustainable methods in the supply chains of this industry as one of the solutions to meet these environmental challenges has been considered by researchers and practitioners in this field. Hence, one of the most important activities is to try to model and ultimately optimize these chains. The present study aims to be able to provide a framework for the development of a mathematical optimization model of the country's sustainable gasoline supply chain. Therefore, in addition to providing an executive framework, it also deals with the methods of data collection and analysis of each of the executive steps of the proposed framework. By using the proposed framework, the goals explained in the strategic document of comprehensive energy planning of the country regarding the adoption of optimal and sustainable strategic decisions can be achieved.

Interaction is a process that determines the bias of the relationship between actors. This bias can be convergent or divergent. The formation of the social organization of human society can occur only on the basis of convergence among actors, as members of that organization. Therefore, the purpose of this study is to present a model of social action in the Iranian engineering system and its optimization. This research is a quantitative research and it is applied in terms of purpose and in terms of descriptive-survey nature. The statistical population of Tehran Province Building Engineering Organization is 510 people. Using Morgan table, 219 people were selected as a statistical sample using simple random sampling method. The data collection tool is a questionnaire whose validity according to Professors and experts and its reliability was confirmed by Cronbach's alpha (0.7). After extracting the dimensions and components from the theoretical foundations, using the three-stage fuzzy Delphi technique, the theoretical saturation of the model was achieved. To form an expert panel, 12 university professors who had special expertise conditions were used. After testing the model, SPSS software was used for hierarchical clustering and finally MATLAB software was used to optimize the main dimensions. The results showed that the efficiency of the model in the current situation is 0.41 and the gap between the current situation and The ideal position (maximum value) is 0.13 in the compliance variable, 0.15 in the achievement variable, 0.06 in the coherence variable and 0.03 in the pattern retention variable.

The extent and diversity of oil and gas resources on the one hand and the low price of energy carriers in the country has made Iran one of the highest consumers of fossil fuels, therefore, various approaches and policies have been presented to reduce this, one of them Relying on social capital. Therefore, the main research question is to what extent social capital can be used in the optimization of fossil fuels? The main hypothesis of the article is that due to sufficient social capital in the field of trust, social cooperation and popular organizations (although there is less belief in this), the capacities of social capital indicators can be used to optimize fuel consumption. The results of the research show that based on the field data, the horizontal trust index (trust of people to people) is relatively strong among Iranians and they have shown high social cooperation in various crises. At the same time, although Iranians have not shown much faith in popular organizations, membership in religious groups and delegations can compensate for this. The research method in this article is descriptive-analytical, and the data was collected in a library and through a questionnaire.

At present, there is a gap between the current and the desired state of Islamic civilization, which has led thinkers, leaders and political activists to make every effort to create a new Islamic civilization and the necessary state-building outlined in the Step Statement. Numerous strategies may be used to achieve this. This study is an attempt to answer the question: What strategy can bring the current situation of the Islamic State closer to the desired situation more quickly? And test the claim that by adopting a strategy of optimizing political power, opportunities are provided that can accelerate the achievement of the desired situation. This research has been done by swat method and the research findings show that the optimization of political power resulting from the use of a set of indigenous capabilities can provide the conditions for changing the status quo and achieving the desired Islamic state-building context.

The increasing complexity of today's societies is placing more and more of a burden on developmental and political stability, and with developing countries and civil institutions this seems to particularly stand out.Whether they are civil or state-made civil institutions, if they have a layout that can serve all social and political capacities, they bring with them a political order that gradually progresses to sustainable development, reduces the likelihood of political deterioration, enhances the country's political power and will at best increase it to the optimal level.The current arrangement of civil society organizations in Iran is such that, they are not only not in a position to provide the optimal level of political power for the Islamic Republic, but, on the contrary, due to their weaknesses in utilizing all social capacities, they have placed unabsorbed sectors on the path of the declining political power of the Islamic Republic, thus creating serious obstacles to political development. However, the question which arises is, what role will the layout of civil society play in optimizing the political power of the Islamic Republic of Iran in the future?The present study investigates the layout of civil society organizations and their trends. This is done using the scripting method of scenario writing and by determining the necessary indicators to find answers to the above question, to identify the possible scenarios and to achieve the optimal scenario. The propellants were identified by analyzing the effects of the variables using the Mac software.The results of this study show that among all the scenarios, the scenario, where civil society organizations have the highest degree of benevolence, influence, and have the most for-profit purposes, is the one most likely to increase, create and optimize political power.

The Organization of urban spaces based on native and local approaches with a focus on the preservation of ancient-historical monuments demands a particular scientific and administrative process. The historical texture of cities plays a key role in developing tourism and entertainment activities, social and economic activities in urban areas, and urban management. Accordingly, it seems necessary to organize historical cities based on scientific optimization and renovation principles. The purpose of the present study is to organize the urban spaces of the coastal city of Siraf in order to protect its valuable historical monuments. In doing so, the researchers have employed a descriptive-analytic method based on document, library, and field studies in the city of Siraf on the coastline of the Persian Gulf. The required data were collected from the whole city and analyzed in correspondence with the past and present conditions of this city. Given the dispersion of the historical areas of Siraf, its structure and linear shape, its place in the urban network of Kangan county, and the population changes there, the findings of the study indicate that the physical expansion and formation of the new urban spaces have created a variety of problems and difficulties for the optimal exploitation of Siraf’s historical texture. Hence, considering the significance of the historical texture of Siraf in developing, optimizing, and renovating this city, extensive care is required to preserve it. In line with such considerations, the authors have provided some administrative priorities and strategies for the organization of the urban spaces of Siraf in order to enhance its future prosperity, development, and dynamism.

In human societies, energy has a significant role, and it has been used in different ways in any phase of human history. The statistics show that the dependence of the world on nonrenewable resources will not be declined in the future years. This situation has motivated industrial countries to adopt optimization energy consumption policy since some years ago. In general, those countries owing natural resources also have to put optimization policies in their economic and energy policies in order to achieve their own maximum utility or national interests. Therefore, the adoption those policies influencing both demand and supply sides of energy is a non-deniable reality.
