The academic forum was divided into four groups for presentations. Firstly, under the hosting of Professor Li Min, the "Operations and Green Supply Chain Management" group presented their findings. Four doctoral students, Pei Yiyin, Wu Mengchu, Liu Yanping, and Chen Wanying, reported on their research work from various aspects such as research background, research ideas, and model construction. Pei Yiyin, a doctoral student from Nanjing University, shared her research work on "Manufacturer Encroachment and Promotional Effort on a Hybrid Online Retailing Platform". She established a game theory model between manufacturers and retail platforms to explore the interaction between promotion effort decisions on hybrid retail platforms and manufacturer encroachment decisions. Wu Mengchu, a doctoral student from Southeast University, reported on her research work "Buy Online and Return Instore in Omnichannel Operations". She proposed a formalized model to evaluate the impact of omnichannel return collaboration on consumer behavior and channel profitability to provide consumers with a better shopping and returns experience. Liu Yanping, a doctoral student from Fuzhou University, shared her research on "Optimal Production and Maintenance Strategies for Manufacturing/Remanufacturing Leasing System Considering Uncertain Quality and Carbon Emission". She established a production maintenance decision-making model focused on maximizing lessor profits by considering the impact of the quality level of leased products on manufacturing and remanufacturing equipment and the remanufacturing rate to study decisions concerning the production and maintenance of the manufacturing/remanufacturing system. Chen Wanying, a doctoral student from Fuzhou University, presented her research work on "Patent licensing remanufacturing decision considering carbon trading policies under the lease-sale channel". She studied the patent licensing remanufacturing strategy under CTP's leasing channels, constructed a supply chain comprising OEM and TPR,  further analyzed the impact of CTP on OEM and TPR decision-making, and considered the production strategies and profit changes under information asymmetry.


"Operations and Green Supply Chain Management" group presentation


Subsequently, the "Logistics System Optimization and Management" group had presentations from three doctoral students: Zhou Ruiqi, Zhai Youzi, and Yao Hua, who shared their research work. Doctoral student Zhou Ruiqi from Nanjing University presented her research work titled "The Last-Mile Delivery Strategy: Relay Station Service or Delivery at Home?" Her study investigated when express service providers choose to use third-party relay station services under various competitive conditions. She also discovered the existence of a threshold for relay fees and analyzed its impact on demand and profits in monopoly situations. Doctoral student Zhai Youzi from Southeast University reported on her research entitled "Allied Two-tier Hospital Systems: A Comparison of Two Resource Sharing Strategies." She aimed to provide guidance for decision-makers creating higher social welfare, resource utilization, and sustainable hospital alliances, proposing a solution involving constructing a two-tier hospital system consisting of ULHs and LLHs to address resource utilization imbalances. Doctoral student Yao Hua from Southeast University presented her research on "Analyzing the Threshold Effect of Environmental Regulation and Logistics Industry Agglomeration on Road Green Logistics Efficiency." Using the Super-SBM model and panel regression model, she conducted an empirical study on the relationship between environmental regulation, logistics industry agglomeration, and RGLE.


"Logistics System Optimization and Management" group presentation


Then, under the hosting of Professor Xue Weili, the presentation of the "Artificial Intelligence Technologies and Methods" group began. Three doctoral students, Deng Ming, Zhang Linjing, and Xu Lipeng, shared their research findings. Deng Ming, a doctoral student from Southeast University, presented his research work titled "Solving Inventory Routing Problems with Single-cycle Random Demands Based on Deep Reinforcement Learning." He proposed an end-to-end framework using reinforcement learning methods to solve the Inventory Routing Problem (IRP). Doctoral student Zhang Linjing from Southeast University reported on her research titled "Target-oriented Robust Cold Chain Routing Optimization". She used a target-oriented framework to study how to make decisions on vehicle routes considering acceptable costs and carbon emissions to minimize the risk of violating customer expectations for freshness. Xu Lipeng, a doctoral student from Southeast University, shared his research work titled "Identification of Key Industries for Regional Carbon Emissions based on Interconnected Multilayer Network Coupling". He addressed the issue of traditional single-layer network models being unable to differentiate regional differences and couplings in carbon emission networks. He constructed a single-region carbon emission transfer matrix model and a multi-region carbon emission correlated multilayer network hyper-adjacency matrix model, providing theoretical support for cross-regional collaborative emission reduction and promoting integrated regional development.
