To develop a real-time, adaptive task rescheduling framework for robotic assembly lines using digital twin technology to mitigate dynamic operational disturbances.
Formulated a digital twin architecture comprising physical entities, virtual entities, and a virtual-reality interaction mechanism coupled with a mathematical scheduling model.
Established a multi-level rescheduling strategy at the production unit and line levels governed by event-based and user demand-based trigger thresholds.
Engineered an optimization approach combining precedence graphs with an improved discrete fireworks algorithm, evaluated through robotic assembly line task scheduling experiments.
Task scheduling experiments verified the effectiveness of the digital twin model in dynamically adjusting schedules in response to dynamic disturbances.
The improved discrete fireworks algorithm successfully balanced computational time with solution quality to resolve processing time variations and advance delivery requests.
