Economic sanctions imposed on Heterogeneousstates have played an important role as a tool of pressure in recent decades. Considering that most non-conforming states with the US are important players on the energy market, a large part of this country’s sanctions policy has been focused on the energy sector. With the evolution of the US shale oil industry, using energy as a tool of sanctions against target countries has received increasing attention by US presidents in recent years. The US is using the geopolitical shift as an international strategy to compete with other powers in the energy sector such as Iran, Venezuela, and Russia. The US aims to use its energy embargo policy to curtail the influence of these players on the energy market and prevent their anti-American policies by fermenting economic crises within these countries. The question arises as to the extent of the effectiveness and sustainability of this US foreign policy strategy in a transitional international order. The article hypothesis is that due to inefficient unconventional resources in terms of market crisis, the rise of counter-hegemonic coalitions, and geopolitical tensions in regions such as the Middle East, one cannot be too optimistic about the sustainability of this situation. The authors of the article will endeavor to explain the above hypothesis within the framework of the hegemony theory and by using the trend-analysis technique, while addressing the driving forces.

The purpose of this research is designing an Total Interpretive/Structural Model for the Entrepreneurial Orientation of SEM Subsidiary Oil. In this qualitative and quantitative methodology, five university experts in the field of entrepreneurship participated in the meta-analysis and Delphi field to identify the research components and propositions from the same research and then to reach competence. The identified component theory and propositions were analyzed by Delphi analysis. In the quantitative part, with the participation of 25 managers of SMEs Subsidiary Oil Subsidiary Oil and using matrix questionnaires, the identified propositions were stratified into a range of most influential propositions to the least effective ones. The results in the qualitative analysis section illustrate the existence of 3 main components in the form of the 15 final statement based on theoretical adequacy and are quantitatively identified; (X4) As Entrepreneurial Tendency Component Propositions at the Level of Information Technology Capabilities and Proposals to Change Traditional Warehousing (X7); Agile Production by Scale-Saving (X8); and Cost Control through Timely Evaluation of Machinery Depreciation (X9) Entrepreneurial at the competitive level The most influential causes in the oriented SMEs Subsidiary Oil Technologically are the entrepreneurial businesses.

The United States is the world's first producer and consumer of oil and play a special role in international oil market relations. In a sense, due to the differences in the energy programs of the parties of this country, we will see significant changes in the international energy markets. The Trump's economic thinking in business field is based on the neo-mercantilist while the Democrats believe in global and multilateral trade. The most important energy policies of the Republican Party are the development and expansion of fossil fuel production, increasing the share of the oil market, lifting environmental restrictions, confronting OPEC, and unilateralism in the oil and gas trade. In contrast, the Democrats' most important plans in the US election are to return to the Paris Agreement and re-impose environmental restrictions, reduce oil production through legal sanctions such as taxes, expand renewable energy and use financial resources to manage the oil market and trade convergence. The main question of this article is what effect do US parties energy programs have on the oil market? The method of this research is a qualitative in a descriptive-analytical manner using desk research.

Supply chains have experienced rapid growth in recent years. Focusing purely on economic performance to optimize costs or return on capital can no longer guarantee development or sustainability in the chain. Hence, the concepts of green SCM and SSCM emerged to emphasize the importance of social and environmental concerns along with economic factors in supply chain programming. Using the SD method and considering KM , this study investigates the variables related to this topic and the variables of sustainable supply chain management and it determines the relationships between these variables and their impact on the research purpose. To achieve this, first, previous studies are reviewed, and the relevant variables are extracted and finalized according to the experts. Next, SD modeling is designed and various scenarios are defined by changing the effective values of the system. Eventually, several policies are presented to achieve the optimal situation. The optimal values for the ten main influential variables are extracted according to the expert opinion and the effects shown in the model are determined by these changes.

Companies need to exactly manage their assets to balance performance, risk, and cost. The ability of an equipment to provide a certain level of performance is influenced by its design, utilization, deterioration, and its life. On the other hand, in order to obtain the desired level of performance and reduce risk, proper planning of maintenance activities during the period must be done. To manage this issue, organizations must develop a suitable method for their assets from the acquisition stage to the disposal to obtain the required processes and, ultimately, to earn the desired profit. In this study, considering Pipe line as a case study and identifying the LCC, risks and three indicators includes of reliability, availability and maintainability as KPIs. They were weighted by using the opinions of eight expert and DANP method. The final weights of LCC, risk and KPI Respectively are: 0.269, 0.301 and 0.429. Considering different strategies in each phase of the asset life cycle, different scenarios described for the equipment life cycle as follows: 1)Buy- RCM- Replacement 2)Buy- RCM- Overhaul 3)Buy- CBM- Replacement 4)Buy- CBM- Overhaul 5)Buy- TPM- Replacement 6)Buy- TPM- Overhaul. Finally, based on the gained expert’s viewpoint from questionnaire and MOORA technique to rank the scenarios the desired scenario (Buy- TPM- Replacement) was selected.
