Introduction

As the level of urbanization continues to rise, urban density will continue to increase, making the urbanization process increasingly complex.

In this context, the concept of "smart city" has emerged and has become a key tool to solve urban challenges. It integrates different the core of smart city is to integrate infrastructure into a "system of systems".

Stakeholders, including users, and infrastructure within each smart city extend the lifecycle scope (see Figure 1).

A major advantage of the "system of systems" is that the specific performance of all infrastructure in their respective areas can be measured against their impact on the overall city.

Through this verification process, these overall goals can be adjusted and the contribution of each infrastructure can be obtained.

Therefore, by integrating and operating smart city infrastructure and verifying and updating it throughout its life cycle, the expected goals of smart cities are always achieved efficiently (see Figure 2).

Currently, the owners of various infrastructures focus on combining subsystems without ensuring that the types of infrastructures are to ensure the overall coordination of the technical requirements of smart city infrastructure, we first need to clarify the functions of each subsystem should be configured according to the needs of the smart city. Secondly, it is also necessary to fully consider the demands of various stakeholders and Life cycle construction and operation of infrastructure.

To address these issues, this document focuses on achieving a fully functional smart city infrastructure, based on GB/T 45844-2025.

The general framework and process for the development and operation of smart city infrastructure proposed by ISO/T R37152.2016, MOD focuses on three aspects.

Elements (see Figure 3).

---Element (A). Component specification allocation and confirmation of allocation procedures;

---Element (B). Internal/external exploration, planning and operational strategies for smart city infrastructure;

---Element (C). Sharing and interaction of information among relevant parties.

All stakeholders will benefit from applying this framework (see Chapter 5).

GB/T 45845 "Smart City Infrastructure Integrated Operation Framework" aims to provide a framework for smart city infrastructure business collaboration (including process and method), which is intended to consist of two parts.

--- Part 1: Full life cycle business collaboration management guide. The purpose is to provide a clear understanding of the development and operation of smart city infrastructure.

Implementation guidance for "Element (B). Internal/External Exploration, Planning and Operational Strategies for Smart City Infrastructure" within the framework and process.

--- Part 2: Development and Operation Guide. The purpose is to provide a common framework and process for the development and operation of smart city infrastructure the implementation guide for "Element (A). Component specification allocation and confirmation of allocation procedures" in the Smart City Infrastructure Appropriate measures should be adopted to ensure coordination.

Note. The infrastructure, stakeholders and life cycle stages shown in the figure are for illustrative purposes only and could include other infrastructure such as urban agriculture systems.

1 Scope

This document provides a framework (including processes and methods) for business collaboration in smart city infrastructure.

Note 1.The framework proposes synergies between infrastructures, between infrastructures and stakeholders, and between infrastructures and the external environment.

NOTE 2 This document aims to better identify and manage the coordination of smart city infrastructure.

This document applies to both new construction and renovation projects.

Note 1.New projects, i.e., the simultaneous planning and design of smart city infrastructure, are conducive to improving the overall operational efficiency of new major infrastructure projects.

and value.

Note 2.The transformation project is a further expansion on the basis of the first type. In view of the increasing interdependence and complexity of urban infrastructure, smart A new model of urban system integration management is designed to effectively support and optimize the governance efficiency of existing urban areas.

It takes into account the rapid development of technological innovation and environmental sustainable development in the country.

Note 3.This document provides a management case (not a management system) for the integrated operation and coordination of smart city infrastructure.

The scope of the smart city infrastructure is to ensure that the different systems that make up the smart city infrastructure are coordinated with each other and do not overlap with existing work related to individual infrastructures.

The infrastructure shall be implemented in accordance with relevant standards during the construction and management process.
