The Electric Energy Sector of Kazakhstan: State and Vision for the Country Taking into Account the International Trends

The main objective of this paper is the study of the modern state of the electric energy sector of the Republic of Kazakhstan, as well as the determination of some promising directions of the country in view of the global trend of the electric energy sector. The desk study, trend analysis, and literature review were used as the methods of the research. The conducted research allowed concluding that many factors had significant influence on a rapid change of the global energy sector and the way energy was produced and consumed as well (including the climate change, development of new sources of energy, application of innovative technologies). Nowadays, the electric energy sector of the Republic of Kazakhstan is facing a lot of intrinsic factors (including the need to modernize infrastructure), as well as the changes in global markets which require long-term planning and the environment for attracting new investments. It is necessary to take into account the global energy environment during the development of a growth strategy, including some changes in the dynamics and organization of the world production and demand in energy, development of renewable energy resources, and implementation of "smart" networks. Keywords: electric energy sector, fuel and energy complex, alternative sources, renewables, energy infrastructure. JEL Classifications: Q20, Q42 DOI: https://doi.org/10.32479/ijeep.774

Economic rationale for determining the optimal layout of racks and aisles in enclosed warehouses for single piece cargo

The purpose of this study is to substantiate the effectiveness of the selection of options for the placement of racks and aisles in covered warehouses for single-piece cargo. As part of the study, the storage capacities were determined, considering the peculiarities of storage and movement of such goods. To achieve this goal, an algorithm was proposed for selecting the effective placement of aisles and racks in the warehouse. This algorithm considers various factors, such as warehouse capacity, interaction with various modes of transport and reduction of downtime of vehicles waiting for loading and unloading operations at these warehouses. The practical significance of this research lies in the fact that its results make it possible to improve the interaction of various modes of transport through the warehouse, increase the capacity of warehouses and reduce downtime of vehicles waiting to perform operations in these warehouses. This helps to reduce time costs, increase the efficiency and efficiency of warehouses, as well as improve the overall logistics chain of transportation of packaged goods
