A Predictive Maintenance Model for Flexible Manufacturing in the Context of Industry 4.0

Abstract

The Industry 4.0 paradigm is the focus of modern manufacturing system design. The integration of cutting-edge technologies such as the Internet of things, cyber–physical systems, big data analytics, and cloud computing requires a flexible platform supporting the effective optimization of manufacturing-related processes, e.g., predictive maintenance. Existing predictive maintenance studies generally focus on either a predictive model without considering the maintenance decisions or maintenance optimizations based on the degradation models of the known system. To address this, we propose PMMI 4.0, a Predictive Maintenance Model for Industry 4.0, which utilizes a newly proposed solution PMS4MMC for supporting an optimized maintenance schedule plan for multiple machine components driven by a data-driven LSTM model for RUL (remaining useful life) estimation. The effectiveness of the proposed solution is demonstrated using a real-world industrial case with related data. The results showed the validity and applicability of this work.

Digital Twins Approach for Sustainable Industry

“…On the basis of our previous work [29,30], the architecture is organized in three levels: resource, process and application levels. Sensors, IoTs, items of shopfloor and legacy systems are located at the resource level.…”

Strategies to Successfully Implement Industry 4.0 Concept for Predictive Maintenance in Facilities Management

“…However, large organizations must consolidate an integrated approach that will provide facilities managers with a systematic tool for facilities maintenance throughout the buildings' and infrastructures' entire service life (Shohet & Lavy, 2004). To ensure optimal performance and productivity, it is critical to have an effective approach that efficiently coordinates the failure prediction or detection and maintenance plan (Sang, Xu & De Vrieze, 2021). So, the concept of PdM is built on applying data analytics tools to evaluate operating data received via sensors which have the potential to close the gap in maintenance procedures by assisting FM teams in taking proactive measures to prevent unanticipated failures without the requirement for costly and time-consuming site inspections (Bouabdallaoui et al, 2021).…”

“…Industry 4.0-enabled implementations are facilitated with the usage of smart technologies such as big data analytics, Cyber-Physical Systems (CPS), autonomous robots, Cloud Computing, Industrial Internet of Things (IIoT), cybersecurity, Machine Learning (ML), Augmented Reality (AR), Data Mining (DM), system integration and simulation (Bousdekis, Apostolou, & Mentzas, 2020;Li, Wang, & He, 2016). The usage of complex machine and equipment in the current industry has dramatically expanded with the introduction of Industry 4.0 concept (Sang et al, 2021).…”

Enhance Supply Chain Resilience through Industry 4.0 - A view of designing simulation scenarios

“…In this architecture, manufacturers can gather industrial data from different machines, IoTs, etc., supply chain data crossing multiple organizations, as well as general news of different regions for monitoring the supply chain and updating regulations. On the basis of our previous work [18,19,20], the architecture is organized into three levels: resource, process, and application. Sensors, IoTs, items on the shop floor, and legacy systems are located at the resource level.…”
