First, we model satellite-target spatiotemporal correlations via STGNN to predict visibility, achieving a prediction accuracy of greater than 95% that meets realtime decision requirements. Subsequently, a collaborative handover mechanism dynamically aggregates adjacent satellite visibility predictions and status parameters, screening optimal successors through relay selection to ensure tracking continuity.

However, typical operational treatment strategies rely on manual tuning and empirical adjustments, limiting process consistency, adaptability, and optimality. This work addresses these limitations and introduces an approach to modelling and operational strategy optimisation of SBR using a finite state machine (FSM) theory. The proposed framework formulates the SBR cycle as a Mealy-type FSM with cycle transitions driven by discrete input events and structured outputs that define control actions. By aligning SBR behaviour with production system principles, the model optimises input sequences and output vector parameters, targeting operational efficiency and treatment quality. This abstraction bridges the gap between process engineering and discrete event system design. Also, it facilitates modular integration with available hierarchical control architectures, supporting automated schedule generation. The advantages include formal verification potential, reduced operator dependency, and compatibility with cyber-physical CIS design requirements.
