A Markov Decision Process model for maximizing overall equipment effectiveness

Journal of Quality in Maintenance Engineering, Год журнала: 2025, Номер unknown

Опубликована: Май 31, 2025

Purpose The purpose of this paper is to present a novel high-level decision-making framework for optimizing Overall Equipment Effectiveness (OEE) in production systems. model can be used schedule the daily and maintenance tasks maximize OEE—a topic that seldom addressed existing literature within dynamic settings. Design/methodology/approach This study introduces Markov Decision Process (MDP) optimize OEE uses availability quality rate as system state vector streamline regarding scheduling. MDP was solved by policy iteration algorithm, with objective maximizing OEE. demonstrated through an industrial case demonstrating practical effectiveness improving Findings finds using MDP-based approach significantly enhances Through study, we show provides better outcomes compared traditional methods. effectively balances availability, performance, components, leading improved efficiency reduced downtime. Research limitations/implications research primarily focuses on state, which, while effective decision-making—such allocating time rather than specifying exact tasks—may not capture detailed states Additionally, model’s reliance real-time data may require high levels accuracy consistency, which could limitation systems less comprehensive monitoring capabilities. Future studies expand include additional metrics. Practical implications proposed decision-support tool managers environments. By schedules rate, helps reduce downtime, improve equipment utilization, enhance product quality. useful industries looking optimal control Social Improving has wide social implications, particularly where enhanced operational leads resource consumption waste. utilization machinery minimizing contributes more sustainable practices. Originality/value offers unique contribution field modeling , state. Unlike most focus measuring OEE, aims facilitate increasing sensory modern industries, direction holds significant potential application.

Enhancing Quality Control in the Indonesian Automotive Parts Industry: A Defect Reduction Approach Through the Integration of FMEA and MSA

Instrumentation Mesure Métrologie, Год журнала: 2024, Номер 23(1)

Опубликована: Фев. 26, 2024

This article presents the results of research related to measurement system improvement in manufacturing process part box 2ph (luggage on a motorbike).The used an integrated approach Failure Mode and Effect Analysis (FMEA) Measurement System (MSA) identify address critical failures.Begin by identifying potential failure modes through FMEA, prioritizing high-risk modes, then align these with measurements for subsequent evaluation.Implement MSA identified measurements, ensuring system's reliability precision, use guide corrective actions improvements, creating synchronized enhance overall quality.The limitation integrating FMEA that focuses only involves limitations addressing non-measurement aspects failures, such as design issues, variability, qualitative aspects, so it may not provide holistic picture risk processes.Key findings showed errors measuring instruments, recorded check sheets, were focal point urgent improvement.Root cause analysis implicated factors at start project lack confirmation from department.In response, key initiatives involved full calibration control schedule, appraiser training consistency skills perceptions, additional operators quality checking diameter sizing reduce workload.Prior improvement, revealed significant level uncertainty, Gage Repeatability Reproducibility (GRR) value reaching 76.90%.Implementation improvements resulted dramatic reduction GRR 8.97%, signaling positive transformation system.The previously unacceptable became reliable, Number Distinct Categories (ndc) values 15, indicating providing information changes.The this study valuable insights further development industry.By focusing strategies involving strengthening appraisers, adding operators, can be achieved.The implications create foundation proactive, datadriven preventing failures processes.

The current era provides challenges for several automotive industries to be able compete and maintain the quality of their products. For four-wheeled auto­motive companies, satisfying customers regarding visual appear­ance vehicle body is very important. However, internally, companies still found many defects or failures in painting, amounting 32.6%. Apart from that, rework also results additional costs that company must incur during painting process. This study aims clarify types defects, analyze root causes, provide solutions, improve process capabilities, in­crease sigma level industry. uses Lean Six Sigma method, which integrated into DMAIC approach other improve­ment tools. As a result, this clarifies four critical orange peel section, craters, melting, blur. has resulted corrective action including tightening supervision performance section operators so they are consistent committed working according Standard Operational Procedure (SOP) work instructions have been created.
