20.500.12556/DKUM-96323 Optimization of operations in bus company service workshops using queueing theory Public transport companies are aware that the success of their operations largely depends on the proper sizing and optimization of their processes. Among the key activities are the maintenance and repair of the vehicle fleet. This paper presents the application of mathematical optimization methods from the field of operations research to improve the efficiency of service workshops for bus maintenance and repair. Based on an analysis of collected data using queueing theory, the authors assessed the current system performance and found that the queueing system still has spare capacity and could be downsized, which aligns with the company’s management goals. Specifically, the company plans to reduce the number of bus repair service stations (servers in a queueing system). The main question is whether the system will continue to function effectively after this reduction. Three specific downsizing solutions were proposed and evaluated using queueing theory methods: extending the daily operating hours of the workshops, reducing the number of arriving buses, and increasing the productivity of a service station (server). The results show that, under high system load, only those solutions that increase the productivity of individual service stations (servers) in the queueing system provide optimal outcomes. Other solutions merely result in longer queues and associated losses due to buses waiting for service, preventing them from performing their intended function and causing financial loss to the company. queueing theory service workshops buses maintenance traffic information transmission public transport javni potniški promet prenos prometnih informacij vzdrževanje avtobusi servisne delavnice true false true MDPI AG Angleški jezik Slovenski jezik https://www.mdpi.com/journal/vehicles © 2025 by the authors Članek v reviji 2025-12-18 14:31:46 2025-12-18 14:31:46 2025-12-19 03:18:34 0000-00-00 00:00:00 2025 0 0 17 str. št. 3, št. članka 82 Vol. 7 Jul. 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2025-06-20 2025-07-27 2025-08-06 656.1 261658371 10.3390/vehicles7030082 2624-8921 vehicles-07-00082.pdf vehicles-07-00082.pdf 1 0ADEB4201EED404C5B2569C2522036E4 cec4f2805551734971446845bd8cbab94cfb7e0dfe5102545af818cb4c5ce585 35b3543a-dc16-11f0-af12-00155d580e02 https://dk.um.si/Dokument.php?lang=slv&id=201536 https://www.mdpi.com/2624-8921/7/3/82 0 3ce21986-dc16-11f0-af12-00155d580e02 https://dk.um.si/Dokument.php?lang=slv&id=201537 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo 0 0 0
