Faced with a Chinese market encompassing over ten million installed elevator units and a structural shift from "incremental expansion" to "stock optimization," industry upgrade has become an inevitable trend. In the safety domain, research focuses on proactive technologies such as bio-inspired 3D-printed energy-absorbing materials, Prognostics and Health Management (PHM), and seismic risk analysis. In the realm of intelligence, technologies including agent-based group control scheduling, digital twins, and IoT platforms are driving a fundamental transformation of operation and maintenance models from "passive response" to "active early-warning." Within the service sector, the industrial value chain is extending from manufacturing towards "manufacturing + services," catalyzing new models like full-lifecycle management, ondemand maintenance, and policy-driven regulatory optimization. The review indicates that multidisciplinary crossover and deep industry-academia-research integration are pivotal for steering the elevator industry towards safer, more intelligent, and greener development. 2025-01-01T00:00:00Z https://rep.bntu.by/handle/data/163713 Research on the intelligent transformation for small and medium-sized manufacturing enterprises in Zhejiang province Zhang, Taoyuan; Lin, Chenlei; Qiu, Jier; Su, Dongjian; Zhang, Wei; Zheng, Jiageng This paper examines the current status and identifies four core dilemmas of intelligent transformation of SMEs in Zhejiang. Drawing on domestic and international advanced experiences, the study proposes targeted countermeasures to provide theoretical support and practical references for promoting the intelligent transformation of Zhejiang’s SMEs and advancing the construction of a global advanced manufacturing base and a strong digital economy province. 2025-01-01T00:00:00Z https://rep.bntu.by/handle/data/163715 Digital transformation of supply chains in Chinese industrial enterprises Yakushenko, K. V.; Ke, Sun Against the backdrop of accelerating global industrial chain restructuring and digital transformation, the digitization of supply chains in Chinese industrial enterprises has become critically important. Based on this, the paper constructs an organizational-economic mechanism model with a "driving layer-core layer-supporting layer" and perorms an empirical test through case studies of Chinese enterprises. The results indicate that such a mechanism greatly improves the operational efficiency of supply chains, the capability for collaboration, and the ability to innovate. It provides practical recommendations to enterprises and policymakers to facilitate transformation. 2025-01-01T00:00:00Z https://rep.bntu.by/handle/data/163710 Handheld visual inspection technology: components, applications, challenges and trends Wenwei, Dai; Yulong, Gong; Linya, Chen As an emerging interdisciplinary field integrating machine vision and portable devices, handheld visual inspection technology is widely valued for its flexibility, low cost, and strong usability. It overcomes the limitations of traditional fixed systems in volume, cost, and adaptability, with broad prospects in industry, healthcare, cultural relic protection, and agriculture. This paper systematically sorts out its development status: it summarizes research background, significance, and existing deficiencies via literature review; details core hardware/software components and the workflow from image acquisition to feedback; classifies application scenarios and verifies practical value with cases. 2025-01-01T00:00:00Z
