Systems analysis and engineering, decision-making systems are based on data completeness and their validation. The study aims to provide the following grounds for a systematic comparison of economic and environmental performance of vehicles with different fuel drives. The issue of logistical attractiveness and compatibility for Ukraine is especially relevant today. Thus, specific fuel consumption is calculated by determining the cost of electricity that goes to charge the traction battery from the mains and is equivalently converted into the cost of fuel. The paper presents a method of calculating the equivalent fuel consumption for electric vehicles according to European (l per 100 km) and American standards (miles per 1 gallon). According to the results of fuel efficiency studies, it is established that the equivalent fuel consumption on the territory of Ukraine of the studied electric vehicles is 8-10 times lower than the fuel consumption of cars of the same class with internal combustion engines.

During that time frame, existing infrastructure, logistics, and involved materials were at risk of being stolen or by being destroyed due to direct combat damage or resulting fires. Established food transportation routes suffered from blockades, destruction, or congestion. Switching modes of transport for crop grains proved difficult with the absence of required transport and logistics support. The switch to vegetable oil transport proved harder still. Meanwhile, the reestablished naval transportation shed a spotlight on GIS instruments that became critical for the safety of regional food supply chain. This inspired the idea of implementing methods of assessing the safety of transport facilities with the direct participation of the user based on geographic information. These methods can be key in enabling new export routes as part of a stable grain supply chain, supporting logistics behind constructing pipelines for transportation of vegetable oils. As the food safety of the world depends on new export routes, ensuring their efficiency and security will always remain relevant. Description: The proposed review covers the first half of 2022, which is a relatively limited period for analysis, especially given the martial law conditions that have prevailed in Ukraine for more than five months as a result of Russia's full-scale armed aggression against the Ukrainian State and not only. This imposes certain requirements for reporting emergencies of various levels. At the same time, the relevance and necessity of the publication is noted. For 6 months of 2022, compared to the same period of 2021, the number of fires increased by 40.3%, the number of people injured in fires - by 31.3%, the number of injured children and adolescents under 18 years - by 17.3%, material losses - 11.4 times; at the same time, the number of people killed as a result of fires remained at the same level as last year - 49,041 fires were registered [14]. Among them, other causes – 9,069 cases (7.5 times increase), including 6,929 fires that arose because of Russian military aggression against Ukraine. This is without taking into account the fires that occurred in the territories of the Donetsk and Luhansk regions temporarily occupied since 2014 and the territories of the Autonomous Republic of Crimea and the city of Sevastopol, as well as in the territories of certain regions of Ukraine that were affected by Russian military aggression in the period from February 24 to June 30, 2022. A number of fires at grain warehouses were registered throughout June in Dnipropetrovsk, Donetsk, Zaporizhia, Mykolaiv and Kharkiv regions.
