The location problem is defined as a problem on determining where the facility should be located. Determining the facility location considers several factors: distance, customers, and costs. A State-Owned Enterprise (BUMN) that provides public service obligations to procure and distribute rice to beneficiaries (Raskin) is studied as a case study. The case study has 1500 warehouses to support community service activities. In this study, the Set Covering Problem (SCP) and P-Median methods were used to find the optimal number of warehouses to support the distribution of Raskin in Central Java and Yogyakarta (DIY) Province. Regarding the number of selected warehouses, the SCP model gives better results than the P-median. The total number of chosen warehouses is 13 from the SCP compared to 16 warehouses from the P-median. However, in terms of total mileage, the P-median gives a better result than the SCP method in each Divre and Sub-divre, with the total distance by the P-median being 941 Km compared to 1301 Km mileage for the SCP model. The P-median method also gives better results in terms of total distribution costs. [ABSTRACT FROM AUTHOR]

This article examines the operation of the largest US oil companies, which play an important role in the modern world economy and are one of the most strategic economic sectors. It was found that these companies not only determine the general economic policy of the country, but also shape the geopolitical strategy of the United States in other parts of the world. A characteristic feature of the US oil and gas industry is that it is still represented by a large number of producers, however, a possible monopolistic trend will lead to a significant reduction in the number of companies. In addition, one of the main features of the American oil giants is that they actually own only a small number of oil fields (unlike the state-owned companies in Saudi Arabia and the UAE). The operation of multinational companies involved in the US oil industry is based on their unlimited expansion in almost all regions of the world, which involves the large-scale development of oil fields and the opening of oil refineries worldwide. In the process of analysing the impact of the company's development strategy on capitalisation, it was found that the model of American oil and gas multinational corporations is based on the desire to increase their market value. A positive impact on the market valuation of US oil and gas companies is an increase in financial and economic indicators, as well as an improvement in the main operating indicators of production and reserves. In order to improve business efficiency in oil and gas countries, multinational companies allocate certain assets from the corporate structure to increase the total capital of independent companies.
