Improving operation of the croissant production line through overall equipment effectiveness (OEE)

Abstract

Purpose Overall equipment effectiveness (OEE) is a metric for estimating equipment effectiveness of the industrial systems. The purpose of this paper is to identify maintenance improvement potentials using an OEE assessment within the croissant production line. Design/methodology/approach The present work is carried out by analyzing the failure and repair data of the line. The failure data cover a period of 15 months. During this period the croissant production line usually operates over the entire day (24 h per day) in three 8-h shifts per day, and pauses at the weekends. Descriptive statistics of the failure and repair data for the line based on scheduled and unscheduled interruptions were carried. Moreover, the actual availability (A), performance efficiency (PE) and quality rate (Q) measures, together with the complete OEE for each working day for the croissant production line, were shown. Findings The main objectives are to understand the operation management of the croissant production line, and to measure the OEE characteristics in precise quantitative terms. OEE analysis can help the company to identify the primary problems concerning the A, PE and Q and acts immediately. Originality/value This paper presents a successful evaluation of OEE which will provide a useful guide to aspects of the production process, which identifies the critical points of the line that require further improvement through effective maintenance strategy (i.e. total productive maintenance). Moreover, the analysis provides a useful perspective and helps managers and engineers make better decisions on how to improve manufacturing productivity and quality.

Implementing total productive maintenance in a manufacturing small or medium-sized enterprise

“…OEE is obtained by the product of three factors: availability(A), performance(P), and quality(Q) (Tsarouhas, 2019). The relationship between OEE and these three factors (Hedman, Subramaniyan & Almström, 2016) Theoretical cycle time refers to the shortest cycle time that can be achieved under optimal conditions .…”

Analysis and directions of OEE and its integration with different strategic tools

“…Since, it is important to collect and use raw data for the OEE computations, the case studies are the most reliable way to check the results in the engineering sectors. The case study, carried out by Tsarouhas, 78 has analyzed the failure and repair data of the production line through OEE. The data was taken over a span of one and half year which reveals that the production line operates over the entire 24 hours in three shifts each day and halts at the weekends.…”

Overall Equipment Effectiveness: Systematic Literature Review and Overview of Different Approaches

“…Figure 3c indicate the top 10 most productive authors, including the number of articles (N articles) and total citations per year (TC per year). Greek author Panagiotis Tsarouhas was the first in the top 10, with 83.33% of his publications reporting cases in which OEE was applied to different production industries, e.g., croissant production lines [25], ice cream production lines [26] and production plants of Italian cheese [27] to identify potential opportunities for improving production systems. Braglia and Huang published four articles, whereas the other authors from the top 10 published three articles each.…”
