Overall Equipment Effectiveness (OEE) is a Key Performance Indicator (KPI), which describes the efficiency of using technical resources. The index allows improving the efficiency of the production process, and also reflects the potential of the unused production capacity. In the presented case, new possibilities were proposed for the application of this model in public transport. First, the theoretical foundations of machine reliability, as well as the principles of comprehensive maintenance were presented. This discussion presents how to implement the OEE index to assess the effectiveness of vehicle use in a public transport company. Weaknesses were identified in the use of vehicles and changes were proposed to improve the OEE index.

The paper focuses on computer modeling of the reliability of technical systems using FlexSim simulation software. It presents the theoretical foundations of machine reliability and principles of describing this phenomenon. The discussion demonstrates how to estimate the main parameters of reliability analysis - MTBF and MTTR. The end result was designing a simulation model and assessing the impact of machine failure on the productivity and performance of a technical system.
