Method: This research is applicable in terms of objectives and is descriptive research in terms of data gathering methods. The statistical society of this research includes the athletes, experts, and activists of sports media in the context of the Zurkhaneh sport. Because the exact number of this society was not clear, the number of 384 persons were selected by random sampling. Its measuring tool was the researcher-made questionnaire that 12 professors and experts approved its content validity and its reliability was calculated using the compound reliability (Dillon – Goldstein) and was about 0.82. In addition, the SPSS software was used to analyze the data and PLS software was used to preset the model. Results: The results show that the “informing” factor had the maximum role in developing the Zurkhaneh sport with the factor loading of about 0.93. The other factor that had many roles in developing the Zurkhaneh sport was the “social participation” with the factor loading of about 0.91. The “education” factor with the factor loading of about 0.90 was in third place and the last factor was the “culturing” with the factor loading of about 0.90. Conclusions: According to the results of this research, it could be stated that modern media have obtained such power in the communication era that could affect public opinion. Therefore, the potentials of the modern media and their infinite capacity can be used by proper and correct operational planning to make great movements in developing various aspects of Zurkhaneh sport inside and outside of the country.

The purpose of the present study was to optimize and improve the status of ticket sales at Tehran Azadi Stadium and reduce customer waiting times in queues using methods Simulation and Multi-criteria decision making (MCDM). First, using objective observation and time-out, the waiting time for spectators in the ranks of the ticket and presentation and physical examination calculations and then using the simulation software, The entire service process has been simulated from the moment the ticket is purchased until the moment they enter the stadium, and the average waiting time for spectators in the queue for the provision of services is calculated. And then we look at the problems with ticket sales. Also, using interviews with elite and expert people, there are some ways to reduce waiting times for customers in the queue. And each of these views was examined using the simulation software; then scenarios were developed to improve the status quo and then, using multi-criteria decision-making methods, we ranked the scenarios and selected the best scenario.
