Digital twin technology is a crucial enabling technology for achieving management concepts such as digitization, intelligence, and service orientation, and it serves as an effective means to promote the integration of the digital economy with the real economy. As digital twin technology gradually transitions from theoretical research to practical implementation, the requirements for digital twin models have become more diverse, and higher quality standards are demanded. Therefore, establishing standards for the assessment methods of digital twin models is of significant importance for improving the quality level and application capabilities of digital twin models.

On November 1, 2023, the China Information Association released the group standard "Digital Twin Model Assessment Specification," which came into effect on the same day. This group standard was co-drafted by Beijing Boneng Technology Co., Ltd., the Computer Network Information Center of the Chinese Academy of Sciences, the National Industrial Information Security Development Research Center, SANY Heavy Industry Co., Ltd., Dalian University of Technology, the 716th Research Institute of China Shipbuilding Group Co., Ltd., the Aerospace Planning and Design Institute, and a total of 58 other units. The standard is characterized by its strong specificity, operability, and practicality. The introduction of this group standard provides guidance for work in the digital twin field, with comprehensive and substantial content that possesses certain innovative and leading features, filling the gap in standards in related fields.

This document establishes the assessment principles, content, and standardized processes for digital twin models, providing an operational assessment method that can be implemented before the operation of digital twin systems. It conducts a comprehensive assessment of digital twin models to ensure their quality meets the required standards. This set of standardized assessment criteria is provided for builders, users, and third-party assessment organizations of digital twin models, which helps to enhance the quality and application capabilities of digital twin models and aids in their promotion and application implementation.

As one of the participating units in the compilation of the "Digital Twin Model Assessment Specification" group standard, Brilliant Co., Ltd. has been deeply involved in the fields of digitalization and informatization for nearly two decades. With the concept of "infrastructure digitization and digital infrastructure fundamentalization," the company has developed its own intellectual property rights digital twin operating system, BLinkOS. It offers a complete range of industry digital twin application solutions, from data and platforms to professional digital management systems, and is based on big data, cloud computing, and cloud storage architectures. Boneng Co., Ltd. was the first to apply digital twin technology to the civil aviation field and has created benchmark digital twin application cases such as Beijing Daxing Airport, Beijing Capital Airport, and Chengdu Tianfu Airport. Currently, Boneng Co., Ltd. is applying its complete digital twin airport construction experience to fields like smart transportation, smart energy, smart water conservancy, and smart ports.

In the airport field, Brilliant Co., Ltd. has created benchmark cases for digital twin airport projects such as Beijing Daxing International Airport, Beijing Capital International Airport, Chengdu Tianfu International Airport, and Ezhou Huahu Airport. These projects cover capabilities like integrated air and ground operation twin monitoring, digital control towers, virtual inspection systems, and emergency simulation drills and command scheduling. They can empower the entire lifecycle of Type Four Airports, providing support for all lifecycle-related data, processes, and businesses from planning, design, construction, and operation to maintenance.

In the expressway field, Brilliant Co., Ltd. has implemented the Taihu Tunnel Digital Twin Visualization project, offering capabilities including integrated road and tunnel twin display, vehicle twins, traffic flow analysis, environmental monitoring, and event simulation. It has transformed from a single method of operation management that relied only on video monitoring to a comprehensive operation and supervision under the twin platform, which includes the operation status of various facilities and equipment, real-time traffic conditions, and prediction and simulation of various events, significantly enhancing the operation and management level of expressways to achieve knowability, manageability, and controllability.

In the water conservancy field, Brilliant Co., Ltd. has built a digital twin lock dispatching system based on the digital twin operating system BLinkOS. By integrating the operation and dispatching of locks with visualization and combining BIM with GIS, it constructs a 3D visualization model for real-time monitoring and visual presentation of lock operation and dispatching. It allows for a more intuitive view of alarms and issues occurring during the ship dispatching process. It automatically checks for violations during the ship's lock passage through safety monitoring and image analysis. Based on the characteristics of ships passing through the lock, the operation of the lock, and navigation dispatching, it optimizes the ship dispatching sequence under the premise of ensuring navigation safety, achieving system security and flexibility.

Brilliant's Digital Twin Operating System BLinkOS enables users to quickly build and develop twin visualization applications with zero or low code, greatly improving application construction efficiency and reducing input costs. It truly achieves low-code, true twin capabilities. With multiple approaches such as a digital foundation, service platform, IoT platform, and empowerment platform, it empowers users' digital and intelligent transformation and can be widely applied to smart cities, smart transportation, smart energy, smart water conservancy, and other scenarios.
