Introduction: Ports play an important and strategic role in the growth and development of a country; Therefore, the development of ports is an important driver for the economic, social and regional growth of countries. A key and practical concept to achieve port development is the concept of sustainable development. Shahid Rajaei port of Iran is considered the most important import and export gate of the country due to its unique geographical location. Therefore, the most important goals of this research are to identify the effective and key indicators of sustainable development in Shahid Rajaei port of Iran and to prioritize these indicators.
Materials and methods: In order to identify the key indicators of sustainable development in Shahid Rajaei port and prioritize these indicators, by reviewing the literature, sustainability indicators were identified and extracted from the research literature. In the second step, in order to prioritize the indicators, a questionnaire was designed and provided to the sample of the research statistical community. which includes managers, officials and officials of various port departments and experts and experts in this field. The sampling method in this research is a non-probability and non-random judgment. In the next step, AHP and SWARA multi-criteria decision making methods were used to rank the indicators. In the following, related software such as Excel and Super Decisions were used. Finally, average ranks and Copeland methods were used to integrate the results to achieve a prioritization.
Results: According to the obtained results, the economic dimension is the most important dimension of sustainability; Then, social and environmental aspects are important. The findings show that in terms of education level, the majority of research experts have master's and doctorate degrees and are at a high level scientifically. And due to the fact that most of the experts have more than 15 years of work experience, they are experienced people with high work experience.
Discussion: In the environmental dimension, the indicators of identifying types of environmental pollution and waste management were ranked first. In the economic dimension, the index of the amount of investment and the increasing trend of the market share and the index of access to road, rail and air transport lines were ranked first in two methods. In the social dimension, the index of job creation and high quality of port services ranked first. The results of this research can be a basis for the improvement and growth of sustainability in the port and to provide the managers and authorities of the port with proper direction and vision in the field of sustainable development, to take appropriate decisions and actions in the future.

Introduction: Considering the importance of corals in different dimensions of human life, their investigation and study will become more necessary. Kharg and Khargo islands are very important from the point of view of the environment, especially the unique coral covers. In the past few decades, many potential threats such as destructive human activities related to the oil industry and the resulting wastes in coastal environments, oil and hydrocarbon pollution, industrial and urban pollution, air pollution, discharge of municipal effluents and sewage, thermal stresses caused by changes Climatic and fluctuating middle and upper water levels, fishing with nets by fishermen and hunting fish by divers in coral areas, as well as carelessness of divers, have faced many challenges in coral habitats. One of the activities that is in relative conflict with the ecosystem of Khark Island and especially the location of the coral beaches, is the activities and movements related to fishing in Khark and Khargo Island. These activities date back several decades. Extreme poverty in many areas has caused a large number of people to go fishing. Therefore, the purpose of this study is to examine the various aspects of the fishing challenge that threatens the geographical territory of coral reefs. The aim of this study is to emphasize the investigation of human-environmental challenges.
Materials and Methods: In this research, for evaluate and investigate the threats created in the geographical area the first step we investigated the challenges of fishing activity of Khark Island. Then these challenges were classified and finally analyzed and investigated the contribution of each of its aspects in the fishing communities near the coral habitat of Kharg and Khargo islands. In order to investigate fishing and fishing challenges, using the statistical method of Cronbach’s alpha analysis and Likert scale. For trust final results and analyzes must the confidence percentage was calculated and confirmed. The weights of each of the criteria were finalized by the SWARA fuzzy-numerical test. In this questionnaire, there are 21 questions and Cronbach’s alpha is at an acceptable and good level of 0.72.
Results: In the questionnaire of this research, there are 21 questions and the Cronbach's alpha level is at an acceptable and good level of 0.72. It was found that trust in the content of the questionnaire confirms. The effectiveness and weight of each of the criteria showed that the highest percentage of fishing is done by motor boats in the winter season and early in the morning (93%). The results showed that more than 85% of fishermen have not received any necessary training for fishing in coral areas, and this challenge is considered serious and fundamental. The results showed that more than 85% of fishermen have not received any necessary training for fishing in coral areas, and this challenge is considered serious and fundamental.
Discussion: The output indicates that the fishing tool is valued as a criterion with the first rank, in other words, it explains 31% of the weight of the items. On the other hand, fishing time has the lowest weight in the criteria definition with 23%. These statistical processes show that human-environmental factors should be prioritized in examining the challenges and threats of the coral reef in Khark Island. In other words, the control and management of man-made challenges and related factors can create safe coral environments.

The main purpose of this study is to investigate the effect of green supply chain management operations (green procurement, green production, green distribution, green logistics (on environmental cooperation and sustainable performance) economic, social, and environmental (in the country's technology petrochemical company. Literature and research background, a conceptual model of the relationship between these structures was presented, and then the path analysis approach was used to examine the relationship between them. The statistical population of the study consists of 55 experts and specialists of the company due to limited size the population was used as a sample of all members. The research method is applied in terms of purpose and descriptive in terms of data collection method. The output of the Path Analysis showed that: "Green supply chain management operations have a positive effect on" performance "Sustainability" and "environmental cooperation" as well as "environmental cooperation has a positive effect on the performance of sustainability in Fanavaran Petrochemical Company". The output of SWARA technique indicates that the "environmental criterion" with the most weight has been identified as the most important performance measure of sustainability in evaluating suppliers. "Economic criteria" and "social criteria" were also ranked next in importance. Finally, using VIKOR technique, seven suppliers of the company's materials were evaluated and the suppliers were ranked in terms of sustainability performance. The findings of this study are especially useful for manufacturing companies in developing environmental cooperation with their suppliers in order to achieve sustainable performance.
