As an emerging technology in the era of Industry 4.0, digital twin is gaining unprecedented attention because of its promise to further optimize process design, quality control, health monitoring, decision and policy making, and more, by comprehensively modeling the physical world as a group of interconnected digital models. In a two-part series of papers, we examine the fundamental role of different modeling techniques, twinning enabling technologies, and uncertainty quantification and optimization methods commonly used in digital twins. This first paper presents a thorough literature review of digital twin trends across many disciplines currently pursuing this area of research. Then, digital twin modeling and twinning enabling technologies are further analyzed by classifying them into two main categories: physical-to-virtual, and virtual-to-physical, based on the direction in which data flows. Finally, this paper provides perspectives on the trajectory of digital twin technology over the next decade, and introduces a few emerging areas of research which will likely be of great use in future digital twin research. In part two of this review, the role of uncertainty quantification and optimization are discussed, a battery digital twin is demonstrated, and more perspectives on the future of digital twin are shared. Code and preprocessed data for generating all the results and figures presented in the battery digital twin case study in part 2 of this review are available on Github. |

Digital Twins for Construction Assets Using BIM Standard Specifications |
|
10.3390/buildings12122155 |

|
|
Digital twins (DTs) are one of the latest technology trends in all industries. However, DT development in the architecture, engineering, and construction (AEC) industry is still in its infancy. Digital twins have been proposed as tools that can be applied to several challenges in various areas of the built environment. However, their widespread use is hampered due to the slow pace of digitization of the AEC industry, in addition to the absence of a formalized standard for digital twins’ implementation. We began this study by systematically reviewing publications related to DT applications in the AEC industry in four databases, resulting in 229 publications after applying the proposed criteria. The systematic review highlighted the lack of standardization for DTs in the AEC industry. Additionally, this study assessed the current status of DTs and analyzed the evolution of the concept of DTs in the AEC industry. We also proposed a conceptual framework for DT development for construction assets, using the existing BIM information management standards (i.e., ISO 19650) to promote a better interoperable digitalized built environment. |

Mapping the Data Needs and Challenges of Hydraulic Model Development during a Crisis |
|
10.1061/9780784484258.066 |
|
|
|
When crises occur (e.g., disasters, public health emergencies), water infrastructure systems are often forced to operate outside the conditions for which they were designed. Hydraulic models can provide utilities with essential information in a crisis, allowing for near real-time system performance evaluation and informing management response. However, hydraulic modeling remains inaccessible to many water utilities due to extensive data, software, and skilled personnel requirements. Data needs are particularly troublesome because the water sector lags behind other industries in embracing advanced data management and analytics. Researchers have outlined steps to increase data analytics in the water sector and put forth new data management systems in areas such as hydrology and asset management. Notably, a classification system for hydraulic modeling data needs has not been developed. To address this gap, we documented the development of a hydraulic model of the water distribution system serving the University of Texas at Austin. In this study, we (1) classify hydraulic modeling data needs, (2) demonstrate model applications in both a crisis scenario and routine system management, and (3) assess key challenges in modeling. We found that the model can provide helpful insight in a range of management scenarios (e.g., identifying areas of poor system performance), but data-related challenges such as lack of standardization and extensive processing requirements hinder model development. As such, we recommend policy changes that incorporate model development into emergency response plans, ensuring they are in place before a crisis occurs. |

Machine Learning and Data Analytic Techniques in Digital Water Metering: A Review |
Water |
10.3390/w12010294 |
|
|
|
Digital or intelligent water meters are being rolled out globally as a crucial component in improving urban water management. This is because of their ability to frequently send water consumption information electronically and later utilise the information to generate insights or provide feedback to consumers. Recent advances in machine learning (ML) and data analytic (DA) technologies have provided the opportunity to more effectively utilise the vast amount of data generated by these meters. Several studies have been conducted to promote water conservation by analysing the data generated by digital meters and providing feedback to consumers and water utilities. The purpose of this review was to inform scholars and practitioners about the contributions and limitations of ML and DA techniques by critically analysing the relevant literature. We categorised studies into five main themes: (1) water demand forecasting; (2) socioeconomic analysis; (3) behaviour analysis; (4) water event categorisation; and (5) water-use feedback. The review identified significant research gaps in terms of the adoption of advanced ML and DA techniques, which could potentially lead to water savings and more efficient demand management. We concluded that further investigations are required into highly personalised feedback systems, such as recommender systems, to promote water-conscious behaviour. In addition, advanced data management solutions, effective user profiles, and the clustering of consumers based on their profiles require more attention to promote water-conscious behaviours. |
