Petroleum Business Review (PBR)

This research was conducted with the aim of studying the effects of oil and gas industry development on the state of social damage in the native community of Assalouye. This research was conducted using quantitative and qualitative methods, in the qualitative part, the in-depth interview method was used, and in the quantitative part, survey and correlation research methods were used. The population of the current study was the native residents of Asalouyeh, 17 of them participated in the qualitative part using the purposeful sampling method, and 380 people participated in the quantitative part using the random proportional classification sampling method. In order to collect data from the qualitative part, in-depth interviews were conducted with the participants, and the data from the quantitative part was collected using a semi-standard and researcher-made questionnaire. The results showed that under the influence of the oil and gas industry entering the region, social harm has increased significantly. Most of the respondents stated that due to their dissatisfaction with their current living situation, they would move to change their place of residence if possible. The results of the quantitative analysis showed that before the entry of the oil industry, the quality of life can explain the variance of the criterion variable, i.e., the state of social harms, in a significant way to the extent of -20%.

Southeast Asian countries have always been the focus of oil producers due to the increase in population and the trend of economic growth. In the last two decades, Indonesia has been prioritized as one of the new markets for Iran due to its high population and forecast to become the fifth largest economy in the world and the upward trend of energy demand. The purpose of this research is to investigate the capacities of Indonesia using the documentary library research method. Indonesia is a developing country and has an increasing economic and population growth trend, which is facing an increasing demand for energy. For this reason, this market is always the focus of major oil producers.The results of this research show that the refinery capacity of Indonesia's need for petroleum products in the form of joint venture or take-off method to create a sales chain in this country can increase its dependence on Iran. And as a result, more market share can be obtained and also the joint investment cooperation in the upstream development sector with Indonesian oil companies in the direction of developing its fields is also significant. The first question in this research is “what are the capacities of joint cooperation with Indonesia in the field of oil industry”, and the second question is “what are the capacities of joint cooperation between Iran and Indonesia in the field of oil industry?”

One of the most important factors that investors pay attention to in stock markets is stock price fluctuations, which is the basis for evaluating the performance of company managers. The performance of the company's stock includes the yield from the resources under the company's control and is considered a suitable criterion for reaching the set goals. In the meantime, one of the things that influenced widely on the world financial markets is the outbreak of the 2019 Covid-19 epidemic. The Covid-19 pandemic is known as a black swan event since it was a rare, unexpected, unknown phenomenon with a high and universal impact. Therefore, the current research purpose is to investigate the fluctuations in the stock prices of petrochemical industry companies affected by the Covid-19 pandemic. For this purpose, 19 petrochemical companies of Tehran stock exchange were studied between 2017 to 2022. The data gathered daily and included 19 petrochemical companies in 220 working days for 5 years. The results showed that the shock caused by the growth of the corona virus initially caused a decrease in price volatility in petrochemical companies, but after two periods, the reaction of price volatility to the shock was positive. Finally, the shock effect disappeared after seven cycles.

The oil price fluctuations are a debatable issue among scholars. Understanding the appropriate utilization of underground resources is paramount, considering their abundance and historical significance as a crucial source of financial income for Iran. However, oil shocks pose challenges to petroleum exporting nations due to fluctuating oil prices and their reliance on the global economy. This study employs Econometrics models and auto-regression analysis to investigate whether oil shocks significantly affect sustainable development in OPEC countries during 2000-2019. Findings reveal a 'resource curse' affecting the analyzed nations, with rising oil prices having no substantial impact on their gross domestic product. Furthermore, increased oil revenues drive inflation, impeding urbanization and exacerbating inequality (Gini coefficient), indicative of the 'Dutch disease phenomenon. In conclusion, policymakers should prioritize the economy's size and reduce investment risks by formulating attainable long-term plans concentrated on sustainable development indicators, aiming for more stable progress. Oil shocks notably influence the sustainable development of petroleum-exporting countries.

Market uncertainty is when investors have difficulty in assessing current and future market conditions because there is a lot of volatility in the market. This research was conducted with the aim of investigating the effect of environmental uncertainty and currency uncertainty on volatility of stock returns of Petrochemical and Petroleum Products Supplier companies which are listed in Tehran Stock Exchange (TSE); these companies are active in all areas of the supply chain from extraction to retailing. In order to achieve the objectives of the research, research hypotheses were tested based on a statistical sample consisting of 13 companies during a 10-year period from 2012 to 2021 through the GMM estimation method with EViews. The findings of the research show that environmental and currency uncertainties intensify the volatility of companies' stock returns. These uncertainties in the previous period have the opposite effect on the volatility of stock returns in the current period. Also, the relationship of trading volume and stock price variables with stock return volatility is negative, because when market uncertainty is high, traders are expected to move more towards stocks of safer companies. The greater the volatility of returns in the previous period, it is expected that this will intensify the volatility of stock returns in this period as well. Examining volatility of stock returns can be useful in analyzing market participants' motivations.

Cell Formation Problem (CFP) is a famous issues in group technology, where an analyst aims at forming groups of machines/parts (so-called cells), in such a way that machines in every cell process as much as possible parts from this cell and as less as possible parts from other cells. In this article, a Harmony Search Algorithm (HSA) is designed to solve the CFP. In order to evaluate the performance of the proposed algorithm, 35 sample classical problems are examined. The experimental results indicate desirable performance of the proposed algorithm. In addition, applicability of the proposed algorithm is demonstrated by a real-world case in project human resource management. Since the megaprojects in oil industry require a wide range of jobs, thus grouping of individuals with considering their skills is an important challenge. The paper defines the job grouping problem as a CFP, and solve a real-world problem using the proposed HSA.
