At the same time, the efficiency of the logistics system when simultaneously processing large volumes of data and constantly updating it is determined by the speed of processing user requests and the accuracy of the responses provided by the system. Within the retrieval-augmented generation architecture, a hybrid information retrieval method has been proposed, based on the combined use of a vector-graph data representation structure and large language model. Experiments showed that the hybrid method achieved best accuracy rates of 0.24\u20130.25 (among all considered methods) with enhanced scalability capabilities (when the number of nodes increases fourfold, the time increases only twofold\u2014from 0.09 s to 0.20 s) due to the limitation of the graph traversal area when implementing the graph component of the hybrid search. An optimal range of 30\u201350 nodes to be traversed was also identified, balancing precision and query processing speed. The findings are of practical value to logistics system developers and supply chain managers aiming to implement high-precision, natural language-based information retrieval in dynamic operational environments.<\/jats:p>","DOI":"10.3390\/bdcc10020051","type":"journal-article","created":{"date-parts":[[2026,2,5]],"date-time":"2026-02-05T15:24:19Z","timestamp":1770305059000},"page":"51","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Hybrid Method of Organizing Information Search in Logistics Systems Based on Vector-Graph Structure and Large Language Models"],"prefix":"10.3390","volume":"10","author":[{"given":"Vadim","family":"Voloshchuk","sequence":"first","affiliation":[{"name":"R&D Institute of Robotics and Control Systems, Southern Federal University, 105\/42 Bolshaya Sadovaya Str., Rostov-on-Don 344006, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yaroslav","family":"Melnik","sequence":"additional","affiliation":[{"name":"Institute of Computer Technologies and Information Security, Southern Federal University, 105\/42 Bolshaya Sadovaya Str., Rostov-on-Don 344006, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9588-2194","authenticated-orcid":false,"given":"Irina","family":"Safronenkova","sequence":"additional","affiliation":[{"name":"R&D Institute of Robotics and Control Systems, Southern Federal University, 105\/42 Bolshaya Sadovaya Str., Rostov-on-Don 344006, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-6104-6084","authenticated-orcid":false,"given":"Egor","family":"Lishchenko","sequence":"additional","affiliation":[{"name":"Institute of Computer Technologies and Information Security, Southern Federal University, 105\/42 Bolshaya Sadovaya Str., Rostov-on-Don 344006, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1260-8676","authenticated-orcid":false,"given":"Oleg","family":"Kartashov","sequence":"additional","affiliation":[{"name":"The Smart Materials Research Institute, Southern Federal University, 178\/24 Sladkova Str., Rostov-on-Don 344090, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander","family":"Kozlovskiy","sequence":"additional","affiliation":[{"name":"Institute of Computer Technologies and Information Security, Southern Federal University, 105\/42 Bolshaya Sadovaya Str., Rostov-on-Don 344006, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,5]]},"reference":[{"key":"ref_1","first-page":"135","article-title":"Intelligent System for Countering Groups of Robots Based on Reinforcement Learning Technologies","volume":"Volume 329","author":"Ronzhin","year":"2023","journal-title":"Frontiers in Robotics and Electromechanics.
