Predictive Scheduling of Parallel Pump Systems Based on Airport Gate Assignment Peng Liu, Jing Gong, Bohui Shi, Shangfei Song



The pipe network fuel supply system plays a crucial role in guaranteeing the secure and uninterrupted operation of the airport. The issue of high energy consumption in parallel pump systems has attracted much attention and concern. A predictive scheduling method based on airport gate assignment is proposed to achieve closed-loop control. Serving as the foundation for supply optimization, airport gate assignment problem is solved to determine corresponding gates for flight refueling. The hydraulic steady state simulation is carried out to identify the position of the lowest-pressure fuel hydrant. In order to reduce operational energy consumption, the dichotomy method is employed to determine the minimum allowable pressure at the inlet of the pipe network. Taking into account pump switch times as an indicator for pump maintenance, the optimal scheduling strategy is finally achieved through dynamic programming. Operational and maintenance costs are proved to be significantly reduced with the application of the proposed predictive scheduling strategy.
