A Digital Twin and Big Data-Driven Opti-State Control Framework for Production Logistics Synchronisation System

Abstract

The randomness and persistence of dynamic disturbances pose significant challenges to resource integration, task allocation, and goal setting within production logistics system. To maintain the optimal operational state of production logistics system over the long term, predictive planning and intervention must occur before disturbances arise, whereas adaptive adjustments are necessary to correct system states after disturbances occur. However, the effective implementation of these control strategies is hindered by several obstacles, such as a lack of comprehensive data and valuable knowledge, which impedes the support for opti-state control (OsC). Fortunately, with the advancements in information technologies such as the IoT and digital twins, it is now possible to collect and process vast amounts of real-time, full-lifecycle big data, thereby enabling more informed optimisation decisions. This paper proposes a digital twin and big data-based opti-state control system (DTBD-OsCS). The architecture integrates big data analytics and service-driven patterns, effectively addressing the aforementioned challenges. Within this framework, both predictive opti-state control (POsC) and adaptive opti-state control (AOsC) strategies are incorporated, along with the development of key technologies for implementing big data analysis. The proposed architecture's effectiveness is demonstrated through application scenarios, and experimental results and findings are thoroughly discussed. The results show that the proposed architecture significantly enhances the efficiency of production logistics systems and effectively reduces the cost impact of disturbances on the system.
