Mineral industries are one of the important sectors of industry in Iran, therefore, it is necessary to improve the quality of mineral products. One of these products is foundry silica sand. The aim of this study was to create a complete model using this type of silica sand. A comprehensive analysis was done on ten mines and seven mines were selected to perform the quality improvement stage. A total of 1400 tests were conducted to achieve the main goal of the research, which was to increase the quality of silica sand parameters. It was also found that the seven basic characteristics of silica sand have a significant effect on the quality of the final products. The quality of silica sands is influenced by elements such as calcium, sodium, potassium and magnesium, which are alkaline elements of the soil. A higher percentage of silica in a mineral is usually associated with increased quality, as it ensures the achievement of ideal properties and performance in silica sands. Factors affecting the quality of silica sand were prioritized by experts using the fuzzy Delphi technique and hierarchical analysis. These factors have an effect on the chemical composition, purity, reactivity and performance of silica sands. Also, a data mining model was designed to predict the quality of these sands. The findings of this study show that the presence of calcium, sodium, potassium, magnesium, silica content, ADV (sand alkalinity or acidity) and pH affect the quality of silica sands. It is concluded that this model provides an efficient attitude and prediction to increase product quality.

In a city, there are different sectors in operation, and each sector also plays a role in the production of municipal waste, which draws attention to waste management methods. The present study explains a model to identify the factors affecting waste production in Bushehr.

The main dimensions of the model are taken from the review of the theoretical literature. A dynamic systems approach has also been used to identify urban waste management strategies. First, we identified and modelled the factors affecting municipal waste production with dynamic systems. The reasons for using the dynamic systems approach for this research can also be enumerated as follows: 1) an appropriate approach in determining and predicting the effects of factors affecting waste production, 2) helping to understand the relationships between variables and examining the behaviour and structure of systems, incredibly complex systems (creating a conceptual model), 3) a flexible approach with the ability to analyze quantitatively and qualitatively, 4) the ability to review the system in the future under different scenarios and policies of decision makers and 5) dynamic system models are considered as simulation models; therefore, they have the advantages of using the simulation method over the analysis methods. In the next step, the organization's internal and external factors in urban waste management were performed by referring to the SWOT analysis method, urban waste management strategies in Bushehr.

 The results of the SWOT method showed that the vulnerability threshold of urban waste management in Bushehr is very high, and it is necessary to provide appropriate policies to address weaknesses and threats using strengths and opportunities. In the next step, Mikhailov's nonlinear method was used to rank the four strategies. This approach shows that among SO strategies, increasing awareness and changing citizens' attitudes towards proper waste management is in the first place. Among ST strategies, culturing for recyclable containers weighing 0.51 is in the first place. Employing knowledgeable people for proper waste segregation and disposal among WT strategies, with a weight of 0.57, was ranked first, and finally, the strategy of encouraging the private sector to invest, with a weight equivalent to 0.43 among WO strategies, Ranked first. Pollution from poor waste management in urban areas imposes irreversible health and aesthetic consequences on society. Among the consequences of poor waste management will be a variety of diseases. Environmental issues are also at the top of all human problems.

Originality/Value: 

 In this research, an attempt has been made to examine innovation from three aspects: theoretical, technical and practical gaps, which can be mentioned as the strengths of the current research compared to other research. From a theoretical point of view, it has been tried to conduct a relatively comprehensive study of factors affecting urban waste management to formulate strategies. Also, from the technical point of view, the current research is innovative by focusing on combining fuzzy logic with the dynamic systems modelling approach and the Delphi method. Finally, it has been tried to reduce the practical vacuum of previous research in this field by formulating optimal strategies.

The sustainability of supply chain processes is one of the up-to-date infrastructures needed by organizations in tough competitive conditions, so that supply chain sustainability has become a strategic organizational issue. The health system has one of the most complex supply chains due to its relationship with human health, and the drug supply chain is a part of this system. The purpose of this research is "to design a maturity model of supply chain sustainability with a continuous improvement approach in the pharmaceutical industry of Iran". This research is an exploratory mixed research. The first stage of the research is qualitative due to the need to determine the required components of the model. In this stage, using the methods of literature review and systematic review, the required data were collected from scientific articles of domestic and foreign journals and analyzed using the methods of content analysis and thematic analysis, and in the second stage of the research, the opinions of 16 academic experts and An industry was collected and analyzed in the form of quantitative data using a questionnaire in the Delphi method, it is quantitative. The designed maturity model has a descriptive, prescriptive and comparative approach. Designing a supply chain sustainability maturity model for other industries, clarifying the status of the country's pharmaceutical industry's supply chain sustainability using the designed maturity model, and developing a supply chain sustainability standard for Iran's pharmaceutical industry are suggested for future research.

The empowerment of each country in the fields of science and technology requires attention to indigenous knowledge and, of course, the use of the experiences of developed countries in these areas. Therefore, production and technology transfer should be considered together in order to prevent the waste of time and energy, also provide scientific grounds for localization. This is important when the intellectual property of technology transfer, as a supportive power of the technology owner, is also taken into consideration. Because of its importance, in this paper, by presenting a model, we draw a proper path in the production of domestic technology along with the transfer of technology that has been consulted by the elite. The resulting model explains the process of manufacturing and transferring technology from the legislative stage to the product delivery of the technology. In this model four phases of infrastructure, creation, supportive and final are considered. In the infrastructure phase, the legal dimensions of intellectual property laws as well as methods for creating the right conditions for the transfer and production of technology in the Government, Parliament and the Guardian Council are examined. In the phase of creation, the responsibilities assigned to the relevant ministries, as well as the improvement of the power of science and technology parks along with the appropriate direction for them. The supportive phase is a guarantee of the implementation of the law and, in addition, it has a supportive role in creating a suitable platform for technology vendors. Finally, the process of fusing and commercializing technology in the final phase is examined.

With the passing of the era of the first and second generation of university that training-oriented universities and research-oriented universities are called, the third generation as an entrepreneurial university has been introduced. The aim of present article is Identifying and ranking Entrepreneurial University's Structure Dimension. Entrepreneurial university appearance as a center which focus on humanity knowledge and publication of that, investigation, preparation and university attendance on development of economic and social with more operational system, can be known as one of the most important events in recent years. By attention to necessity of developing these kind of universities, must examine structure basis of that and Iran,s universities should be noticed to this kind of university. In this investigation, researchers after library considerations, proceed to recognition of effective structural dimensions on entrepreneurial university using Delphi method in three rounds. then they ranked this dimensions by using AHP. After recognizing dimensions by using Delphi method they ordered by using networking process: integration, independence, professionalism, complexity, centralization and formality. The result of present article shows that scientific system of country should notice to a lot of structural dimension's in the universities especially in independence and integration and professionalism. Because Entrepreneurial University's Structure should persuade creativity and synergy. The leading role, combination of the components of the composition and independence, is the one of the most influential factors that affecting on the structure.
