Mobile Wireless Communication-based Closed-loop Supply Chain Management Network Model

Introduction: The informatization and networking challenges inherent in Closed-loop Supply Chain Management (CSCM), combined with the integration of mobile wireless communication technologies, present substantial barriers to the development of a high-performance CSCM network model. This research seeks to optimize and automate the CSCM process via mobile wireless technologies, thereby enhancing management efficiency and reducing operational expenditures. Methods: A mobile wireless communication-based CSCM network model was developed, consisting of a system service layer, an application service layer, a development environment, and an interface and tools layer. A data acquisition and transmission system was engineered utilizing wireless network technology, with the data acquisition controller and host computer directly linked to a router to enable bidirectional data exchange. This model was applied to a multinational enterprise to evaluate its performance. Results: One year after implementation, the enterprise's maximum procurement duration and cost were reduced by one day and 4.39 million RMB, respectively. Maximum inventory turnover days were reduced by 1 day. The number of suppliers achieving "excellent" performance increased from 7 to 9. Monthly demand planning efficiency and goods management efficiency improved to a maximum of 5.44% and 91.4%, respectively. Discussion: The integration of data acquisition controllers, WiFi modules, and mobile terminals within the CSCM network model demonstrably improves supply chain transparency and operational oversight. The bidirectional transmission capability reduces system complexity and cost, directly contributing to the observed improvements in procurement, inventory, and supplier performance. Conclusion: The study provides a practical and feasible CSCM solution for enterprises. The manuscript does not incorporate reinforcement learning algorithms, as the primary focus lies on the practical implementation of mobile wireless communication technologies within a closed-loop supply chain framework. By analyzing the application of specific electrical devices within this framework, the research delivers a more effective approach to supply chain management, enabling significant operational and financial benefits.
