Summary

With the rapid development of advanced information technologies such as the Internet of things (IoT), big data and cloud computing, the traditional supply chain has been transformed into a digital supply chain. Digital supply chains may help to maintain high growth by reducing operation costs and improving the efficiency of supply chain management with the help of digital methods. As a result, digital supply chains can assist with the construction and management of smart sustainable cities (SSC).

Recommendation ITU-T Y.4910 provides a maturity model of digital supply chain for SSC referring to the key performance indicators (KPIs) for SSCs in Recommendation ITU-T Y.4900 and the maturity model for SSC in Recommendation ITU‑T Y.4904. Both of these Recommendations support the maturity model for digital supply chains. The use of the maturity model for digital supply chains has specific benefits for socioeconomic indicators, such as: environmental sustainability, productivity, innovation, and trade. This maturity model helps identify the goals, levels, dimensions and assessment methods of digital supply chain for SSC. It is designed as a practical tool for city managers and all related stakeholders to study the performance and benefits of digital supply chain from economic, social and environmental perspectives. Thus, this Recommendation gives general guidance for accurately assessing the maturity of digital supply chains and help in achieving sustainable development goals for SSC.
