Infrastructure and development projects in any country constitute the infrastructure and development of that country. In the implementation of these projects, financing is an important and primary concern due to the lack of infrastructure and infrastructure in the country on the one hand and the lack of capital resources on the other hand, capital has an undeniable role in this. Financing projects is one of the most common investment methods in any country. Undoubtedly, how and how to finance the projects for each level of existing institutions depends on the nature of the project. Paying attention to financing has a high share in solving the problems of financing and launching projects. Therefore, the purpose of this study is to rank the methods of financing from external sources in construction projects. The present study is applied in terms of purpose and descriptive-survey in terms of the nature of the method. In order to collect data, a questionnaire based on multi-criteria decision making method (network analysis method) was used, which was completed by five senior financial engineering experts with at least 10 years of experience in financing projects of construction companies in the west of Tehran. The collected data were analyzed by Super Decisions software. The results of financing ranking showed that international loans with a relative weight of 0.314 ranked first, BOT contracts with a relative weight of 0.21 and finance with a relative weight of 0.171 took second and third place. Findings of the study show that in general, the criterion of higher rate of return with a relative weight of 0.64 than the criteria of lower risk with a relative weight of 0.26 and a ceiling of more funds with a relative weight of 0.1 is of higher importance in financing from external sources in the project. Have civil engineering and should be given more attention.

Today, construction is a complex and risky industry, and the progress, development and prosperity of countries depend on the creation and implementation of development projects that are a manifestation of this strategic industry. These projects are complex, costly and time consuming, and due to the large number of people involved in projects and multiple stakeholders, we see claims and disputes during the implementation of projects and these claims and disputes have a detrimental effect on projects and predetermined goals. In such a tense environment which is full of uncertainty, it is necessary to pay attention to knowledge and management of intellectual capital as a way to overcome the differences and challenges in projects and gain a sustainable competitive advantage. Therefore, the present study was conducted to investigate the effect of knowledge management on claim management. The present study is applied in terms of purpose and descriptive and correlational in terms of data collection method. The statistical population of the present study is the members of Fars Province Engineering System Organization. The sampling method was random and available and the sample size was determined by Cochran's formula to 369 people. Data were also collected through standard questionnaires. To assess the validity, content validity and reliability of the questionnaire from Cronbach's alpha were used. To test the hypotheses, linear regression test was used using SPSS software. The results of the hypotheses showed that there is a significant effect between knowledge management and claim management.

Nature and the environment are a gift from God that exists around every living thing and on which survival depends. Given the vast natural resources that Iran has at its disposal, it should be noted that the destruction of natural resources and the environment affects the quality and natural cycle of the country and has detrimental consequences for human life, animals, plants and buildings. Given that nature was created for the survival of the human race and there is an inseparable link between man and nature, so its preservation and protection is very important. Given the accelerating trend of natural resource degradation and the threat of biodiversity, one of the challenges in the field of natural resource protection is to upgrade the protection unit of such areas. The purpose of this study is to identify and rank the effective factors in improving the performance of the Natural Resources Protection Unit. The present study is applied in terms of purpose and descriptive in terms of nature and method. In order to collect, questionnaires based on multi-criteria decision-making methods used in this study (test and evaluation decision-making method and network analysis method) were used by five people. One of the senior experts with at least ten years of experience in the natural resources of Bastak city has been completed. The collected data were analyzed by Excel software and superdecision. The results of identification and effective factors in upgrading the protection unit based on network analysis show that the most weight is occupied by machines and the lowest score is allocated to system updates.
