This paper focuses on the analysis of the petrochemical products manufacturing value chain and the presentation of petrochemical products' optimal manufacturing pattern in petrochemical industries affiliates of pension funds. The case study in this research is JAM and MASJIDSOLEYMAN Petrochemical companies. Period of this research is 5 years. In this case study, the determiner faces paradoxical objectives simultaneously. The fuzzy multi-objective linear programming (FMOLP) method has been used based on the α-cut of fuzzy parameters in this research. The goal of this research is to extract the amount of products that have maximized profit and value-added and minimized risk simultaneously which face technological, market, financial, budget, legal, and national interest-related limitations. This method is often interested in the proper POSs that have finite tradeoffs between objective functions. One numerical sample has been used to show the possibility of using the said method in multi-objective optimizing issues for the production of propylene. Because of the efficiency and satisfaction of the obtained new solutions for this method, this method undoubtedly can be useful to solve the FMOLP problems. A decrease in the production of ethylene and light polyethylene and an increase in propylene and butadiene production is the most important policy recommendation of this research.

Assessing the value of petrochemical industries on the one hand as strategic industries in the provision of raw materials of other parts and on the other hand, given the high weight of the formation of the stock market in Tehran, it is important. This industry, while influencing developments in other markets, especially the oil market, which has a significant impact on other markets, in particular the financial market. The stock prices of the petrochemicals in the stock market are heavily dependent on the price of petrochemical products, as well as the high dependence on oil price changes on global markets. Therefore, the analysis of the relationship between petrochemical price and oil price requires an asymmetrical model. In this study, the effect of oil price on value of the petrochemical industry in asymmetric shape in 2008-2017 periods daily basis has been analyzed using model Shin et al (2014). For this purpose, a nonlinear autoregressive distributed lag (NARDL) approach has been used. The findings indicate that these industries could be the channel for transferring global oil price fluctuations to the total stock market in Tehran. In the short term, anonymity is confirmed by the impact of the oil price on the value of the petrochemical industry. As oil prices decline, the value of petrochemicals decreases, but with increasing oil prices there will not be an increase in the value of petrochemicals. In the long run, oil prices are ............
