The Impact of Single Minute Exchange of Die and Total Productive Maintenance on Overall Equipment Effectiveness

Abstract

Due to intense global competition, manufacturing companies need to improve and optimize productivity, increase production and flexibility, and gain competitive advantages. Companies have begun to look for new approaches and strategies in the field of production management. This includes tools like Single Minute Exchange of Die (SMED) and Total Productive Maintenance (TPM), which aim to manage machines and equipment, reduce waste and lead time, and ensure and enhance competitiveness. The main objective of this study is to explore the connection and the context of the use of industrial engineering tools, namely SMED and TPM, and to monitor and evaluate Overall Equipment Effectiveness (OEE) in industrial companies in the Czech Republic. A comprehensive questionnaire survey of 200 companies and a detailed evaluation of the operational performance of 92 companies were carried out from the third quarter of 2019 to the third quarter of 2020. It was found out that 20.5% of companies implemented SMED, 26.5% of companies implemented TPM, and 54.0% of companies did not monitor and evaluate OEE. The research confirms the theoretical link between SMED and OEE and between OEE and TPM. The statistical significance of the use of SMED and TPM separately was not demonstrated. However, the mutual interaction of using TPM and SMED on the OEE level was proved.
