A NEW SCORING APPROACH TO CALCULATE OVERALL EQUIPMENT EFFICIENCY: A CASE STUDY

Abstract

Purpose: The aim of the study is to compare and analyze Overall Equipment Efficiency (OEE) and Total Effective Equipment Performance (TEEP) metrics, identify deficiencies and suggest a new and usable OEE calculation methodology for a manufacturing company. Methodology: The results of OEE, TEEP, and the proposed method were compared in a faucet production company in Turkey. The defined scorings were used to maintain the structure of the OEE focused on losses, and the TEEP metric was used to include planned downtimes in the proposed method. Findings: According to the results of the study, the proposed metric broaden the structure of OEE that focuses solely on equipment, while maintaining its structure that focuses on losses. Originality: No other study has been found in the literature that compares OEE and TEEP metrics over the same production data, and then focuses on the strengths of the two metrics and proposes a new method. It is predicted that the study will fill this gap in the literature and will be a guide for the development of different new metrics.
