Megjegyzések:	In terms of road transportation, the ratio of newly purchased electric passenger cars is increasing to the detriment of internal combustion engine vehicles. According to current assumptions, this process will continue, but the speed and extent of the change are still open questions. The entire road transport sector is just before a very significant transformation and forecasting this conversion is a burning issue. The changes will arise many challenges, among which growing electricity demand is a great concern. It simultaneously appears to shift towards renewable energy sources in electric power generation. In this work, the growth of newly purchased and already used electric light vehicles is investigated based on the example of Hungary. Taking into consideration the latest available data, the spreading of electromobility is forecasted using an exponential model. It is assumed that the annual new electric car`s number shows exponential growth until the year when all newly purchased light vehicles will be fully electric. Three different scenarios are investigated in the manuscript: one assuming a slow increase, one calculating with a rapidly spreading, and one between these two other options representing the most likely case based on the authors` expectations. Calculating the expected numbers of electric vehicles and their ratio among all light vehicles makes it possible to forecast the additional electricity demand. Based on our opinion, it is a very important and urgent issue, taking into consideration the very long investment and realization time of projects aiming at generating surplus electrical power.

Cím:	Lean Production: Barriers and Impact on Operational Performance / T. Kiss Judit
Dátum:	2026
ISSN:	2195-4356 2195-4364
Megjegyzések:	Companies have to face many challenges during their operations, given that under the pressure of strong market competition, they have to develop, among other things, their appropriate strategy, ensure efficiency and impeccable quality, prioritise the development of their products, or even launch a new product on the market. It is essential to know how to increase the performance of companies in a constantly changing market environment. The aim of the study is to investigate whether company-specific factors and limitations related to the introduction of lean production can be revealed and whether the application of lean practices has an impact on the company's operational and business performance. For the variables to be investigated, we collected data using a questionnaire survey, which were subjected to a thorough analysis in order to ensure the applicability of the PLS-SEM method. Based on the investigations, it can be concluded that the use of lean tools is more typical in companies characterised by foreign ownership than in domestic companies and that there is a significant positive relationship between company size and the application of lean tools. Lean production has a direct positive and significant effect on the company's operational and market performance.
