Abstract
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.
Highlights
Nowadays, ensuring continuity of traffic is a key element in maintaining the competitiveness of enterprises in many areas of human activity
It turns out that the Total Productive Maintenance (TPM) concept is closely related to TQM quality management, the principles of Word - Class Manufacturing and statistical modeling of reliability, which is described in the literature [3,4,5]
The literature [1,2,3,4,5,8,9,10] lists many significant losses that may occur due to the machine's operation, and which can significantly impact all components of the Overall Equipment Effectiveness (OEE) index
Summary
Nowadays, ensuring continuity of traffic is a key element in maintaining the competitiveness of enterprises in many areas of human activity. The academia began to wonder how to prevent failures, instead of anticipating them, and minimizing the effects of downtime It wasn't until the late 20th century that a coherent, popular concept of comprehensive maintenance was developed, Total Productive Maintenance (TPM). The OEE model is widely used as a key indicator of overall equipment performance, which, combined with the increasingly popular Lean Management method, allows the company to effectively increase efficiency. The literature [1,2,3,4,5,8,9,10] lists many significant losses that may occur due to the machine's operation, and which can significantly impact all components of the OEE index. Increased machine availability, no unnecessary machine purchases, comparability of companies within the group in terms of the use of machinery [11,12]
