  The present study sustainable management of Guilan Saravan Sylvan Park was planned. The used method in the form of decision support model in three10-year period was studied for parks of various states and with considering the economic, ecological and social criteria during the years 2008 to 2038. By using hierarchical fuzzy analysis method, the reaching to an optimal level of economic, ecological and social simultaneously and as their combined utility values in various periods, decisions and different states of park is obtained. The results showed that in order to reach to an optimal level of purposes simultaneously, at the beginning of the first 10-year period implementation of ecological decision, at the beginning of the second 10 years period in three considered states for the Sylvan Park implementation of social, ecological and ecological decisions give the most combined utility value of purposes respectively. Results of stochastic dynamic programming showed that implementing the ecological decisions at the beginning of the first 10-year period, implementing the ecological decision by considering the second designed state of park at the beginning of the second 10-year period, and by applying the first designed state of park at the beginning of third 10-year-old period, the implementation of social decisions is desirable to achieve sustainable management in Saravan Sylvan Park. According to the findings, the implementation of these determined decisions can be useful and maximum of desirable use from Park potentials in the economic, social - recreational and conservation and sustainability of indigenous species problems, and reposit the park to the next generation with the best condition.

  The most important relative advantage of Iran has been the export of crude oil and natural gas for a long time. Considering the raw nature of these products, specialization in the production and export of these products will not have a significant impact on Iran's sustainable growth. One of the solutions is to infiltrate the downstream industries of these products, the most important of which is the development of the petrochemical industry. In this sense, since the expansion of export markets is considered as one of the important strategies in the field of marketing, the aim of this research is to identify and prioritize the export opportunities of Iran's petrochemical industry products by developing an integrated decision support model - economic complexity, in five countries that are members of the Eurasian Economic Union. It includes Belarus, Kazakhstan, Russia, Kyrgyzstan, and Armenia, and the member countries of ECOTA trade agreements include Afghanistan, Pakistan, Tajikistan, and Turkey.the current research is applied in terms of purpose, descriptive-survey in terms of data collection, and a mixed type of research. The statistical population of the research was formed by the member countries of ECO and Eurasia trade agreements during the period of 2014 to 2021. First, in order to identify the factors affecting the development of export opportunities, using a questionnaire and a fuzzy Delphi model, based on the opinions of experts working in the private sector and petrochemical companies, experts working in specialized government jobs of the Ministry of Health, and academic experts, Manuscript profile
