1. Introduction

Proactive maintenance is a proactive policy that aims to identify, analyze, and correct the root cause of a failure before it causes further problems and leads to machinery failure. Implementing this policy can enhance reliability, availability, maintainability, and safety (RAMS),

[11]

. As depicted in Figure 1, a digital twin (DT) is a digital version of a physical object or system. It can successfully model a virtual object from its physical counterpart. The main function of a DT is to provide a two-way data flow between the virtual and physical entity so that it can continuously upgrade and improve the physical counterpart,

[5, 6]

. NASA first used the term digital twin in 2010, which was described as “an integrated, multi-physics, multi-scale, probabilistic simulation of a vehicle or system that uses the best available physics models, sensor updates, fleet history, etc., to simulate the life of its flying twin.”

[32, 38]

. Michael Graves was the first to propose the term DT,

[12, 37]

. Recently, DT has been utilized in various manufacturing fields, and it is promoting positive developments in these fields,

[16, 19]

. Kritzinger,

[23]

recognized three levels of DT integration, namely digital model, digital shadow, and digital twin, as shown in Figure 2. Attaran,

[3]

mentioned the main DT applications in manufacturing, as presented in Figure 3. Many diagnostic tools are available to identify and analyze the root causes of failures. Failure Mode Effects and Criticality Analysis (FMECA) is the most common diagnostic method, which consists of two analyses; the Failure Mode and Effects Analysis (FMEA) and the Criticality Analysis (CA),

[18, 40, 11, 37, 43]

. DT enables maintenance management to accurately identify equipment status, proactively predict faults, and enhance reliability,

[1, 2, 4, 26, 47]

. DT contains a set of adaptive models that can emulate the behavior of a physical system in a virtual system, obtaining real-time data to update itself along its life cycle,

[39, 3]

. Figure 4 shows an equivalent representation of the general architecture of DT,

This study focuses on the performance and applications of DTs in proactive maintenance policies and the importance of DT in maintenance management for improving equipment RAMS (reliability, availability, maintainability, and safety). This study is an extension of a previously published paper,

[10]

After this introduction, this paper is organized as follows: In Section 2, the literature review is carried out. In Section 3, the research gap is identified. Section 4 includes the DT framework for proactive maintenance. Finally, Section 5 focuses on conclusions and future directions.

2. Literature Review

Digital twins (DT) can provide a real-time response to the manufacturing system and increase flexibility and reliability,

[13]

. According to Hu,

[16]

Figure 5 illustrates some of the key milestones in the development of DT. In 2016, Siemens used DT devices in Industry 4.0, resulting in a tremendous growth in related publications.

Figure 5. The milestones of DT development.

Proactive maintenance can reduce failure risks, improve system uptime, extend the equipment life, and lower process down time losses. DT can model individual equipment or processes to identify variations that indicate the need for preventive maintenance. The goal is to estimate, predict, detect, or diagnose the condition of the component for more effective maintenance. This can prevent costly failures before a serious problem occurs. They can also determine if better materials or processes can be used or help improve cycle times, load levels, and tool calibrations,

[20, 46]

. The application of DTs enables the monitoring of the condition and prediction of abnormal conditions in machine tools. This greatly enhances the safe and efficient operation of mechanical process systems. Parameter optimization plays a crucial role in the optimization of the operation process. Traditional parameter optimization methods rely on manual experience and often involve high levels of uncertainty. DT operation process facilitates the suppression of errors and the optimization of operating parameters, thus laying the foundation for achieving high-quality and high-level operation,

[16]

DT represents the innovation that has spurred evolution and adaptation in the aerospace industry. For instance, employing DT for an aircraft or rocket ship is believed to enhance global tracking accuracy by 147%. In a recent survey, 75% of Air Force executives favored DT solutions for their industry. DT enables engineers to ensure the safety of the aircraft by looking into the potential aircraft’s problem before any danger. For example, Boeing, the world’s largest aerospace company, uses DT solutions to improve the safety of the parts and systems used to manufacture commercial and military airplanes. DTs of specific aircraft models enable technicians to use augmented reality (AR) overlaying the DT data on the real plane, facilitating faster and more accurate inspections and improving maintenance efficiency. As a result, Boeing has achieved a 40 percent improvement in the quality of the parts and systems,

[29, 49]

. According to GE Research,

[9]

GE’s DT technology is revolutionizing how the aviation industry handles maintenance. Predicting engine wear, such as the blade wear on the GE90, saves airlines millions of dollars in costs and prevents aircraft from landing unexpectedly, especially in areas with sand, a major contributor to the problem.

According to Pinello

[33]

, the European Space Agency (ESA) also adopted the DT approach for its ExoMars mission. They built Amalia, a physical and DT of the Rosalind Franklin rover. This duo serves a vital purpose: anticipating and solving potential problems before they occur on the Martian surface. Overall, using both physical and DTs significantly increases mission success by minimizing risks and improving rover performance.

DTs have been increasingly used in condition monitoring and fault diagnosis (CMFD) in recent years. Table 1 shows the survey of DTs in maintenance over the past years. The details of these studies are explained in the next section.

3. Research Gap Analysis

The literature review shows that the application of DT techniques in proactive maintenance remains very important for managing the maintenance of critical equipment to improve equipment RAMS (reliability, availability, maintainability, and safety) and achieve maintenance excellence. However, there is still a need for a common platform based on creating a physical model via a common methodology. This is a requirement for implementing the DT concept of proactive maintenance. Moreover, implementing DT technology, for maintenance activities in a production plant, requires creating a DT for each machine. Finally, a more detailed review of the literature should also be conducted to identify further gaps, which will be addressed within the framework of constructing and fine-tuning the proposed model.

4. Digital Twin Frameworks for Proactive Maintenance

As mentioned earlier, manufacturing maintenance costs and downtime losses are very high in different sectors, which justifies the investment in creating DTs to optimize maintenance activities. Figure 6 shows a DT model in maintenance,

[10]

According to Dihan

[5]

, data analysis is the technology driver of a successful DT system. Since data is the fundamental difference between a successful and unsuccessful system, proper guidance of data structure should be given due attention. Figure 7 shows the DT data analysis process for building a successful DT.

Hosamo,

[15]

suggested a DT predictive maintenance framework for air handling units (AHU). The proposed framework utilizes DT technology for fault detection and diagnostics and predicts the condition of the building components so that the facility management staff can make better decisions at the right time. Figure 8 shows the principle of a DT in proactive maintenance. The proposed framework includes three main steps, Data acquisition, predictive maintenance process, and BIM model for information visualization and monitoring. Spatial information can be obtained from the BIM model. The BIM model was integrated with predictive maintenance results to support decision-making by developing a plug-in extension for Autodesk Revit using C sharp so that the FM team can easily understand the data. The three main levels of this framework will be explained in detail in the following sections. For facility management, COBie (Construction Operations Building Information Exchange) and Industrial Foundation Classes (IFC) are information exchange specifications for the lifetime capture and transfer of information.

Karkaria,

[21]

introduced a DT framework for proactive maintenance of long-term physical systems. Figure 11 shows the tire health DT framework demonstrating the flow of information, and important components of DT like offline training, model update, and decision making. As shown in this figure, the digital twin begins with the offline training of the Tire Health Temporal Fusion Transformer (TFT) model in Step 1, leveraging historical datasets which has operating parameters (𝑇!) - conditions under which the tire operates, usage parameters (𝑈!) - how the tire is used, and state parameters (𝑀!) - the current condition of the tire. Additionally, within our digital twin framework, we get our dataset with inputs derived from a physics-based Tire Design Finite Element Method (FEM) integrating physical insights with measured data. Incorporating a physics-based Tire Design Finite Element Method (FEM) is crucial to accurately understand the tire's physics-based state, ensuring a comprehensive analysis of its condition through the integration of physical principles with observed data. Then the Tire Health TFT model, a critical component of the Tire Health Digital Twin, facilitates real-time predictions of the damage state. A continuous quantity, named as Remaining Casing Potential (RCP), is considered as the damage state parameter). RCP serves as a key indicator of tire endurance damage, allowing for proactive maintenance decisions. The predictions by the Tire Health TFT model are subsequently compared with real-world instances of tire damages. This comparison allows us to quantify the discrepancy, effectively measuring the difference between the model's predictions and the actual tire damage data in Step 2. We utilize observed discrepancies to refine our Tire Health TFT model. It is important to highlight that, following an update, our model evolves into a hybrid version. Despite this transformation, we continue to refer to it as the Tire Health TFT model for consistency and clarity in our discussion in this paper. Then the updated Tire Health TFT model, with the Tire State Decision Algorithm in Step 3, informs timely tire replacement decisions. Thus, our tire health digital twin has the surrogate model, which is updated in real-time, and aids in making predictive maintenance decisions.

5. Conclusion and Further Work

Proactive maintenance is a policy that aims to identify the root cause of a failure and correct it before it causes further problems and leads to machinery failure. Implementing this policy can enhance reliability, availability, maintainability, and safety (RAMS). This paper focuses on reviewing the applications of digital twins (DT) in proactive maintenance. DT can be used as a data-driven digital concept or technology to effectively address critical equipment maintenance issues. DT enables maintenance management to accurately determine equipment status, proactively predict faults, and enhance reliability. The application of DT technologies remains a critical proactive technology for critical equipment to improve equipment RAMS and achieve maintenance excellence. Several DT frameworks for proactive maintenance have been discussed. Furthermore, this study provides a comprehensive roadmap for future research initiatives aiming to fully utilize the capabilities of technology design teams.

In future activities, the author plans to integrate DT methodology and Lean Six Sigma approach into a more general maintenance management framework for critical equipment whose main role will be to assess and improve the health status of machines, improve reliability, and plan maintenance activities.
