Outline
To address the challenge of coordinating and scheduling construction vessels in large-scale water projects such as waterway regulation, this problem is modeled for the first time as a Dual-Resource Berth Allocation Problem (DR-BAP). A mathematical model is established with the objective of minimizing vessel waiting costs and resource preference mismatch costs. To solve this Non-deterministic Polynomial-time hard (NP-hard) problem, a Two-Stage Hybrid Cuckoo Search Algorithm (TSH-CSA) is proposed. In the first stage, the algorithm employs dynamic priorities, a load balancing guidance strategy, and a historical congestion feedback penalty mechanism for macroscopic resource allocation. It integrates domain knowledge and feedback information to optimize fitness evaluation. In the second stage, the algorithm integrates an adaptive dual-population mechanism and an intelligent restart mechanism to achieve a microscopic, refined solution. Overall, the algorithm establishes a global iterative framework of "allocation-scheduling-feedback" to enhance its global optimization capability. Simulation experiments based on a waterway regulation project show that, compared with the standard Cuckoo Search Algorithm, TSH-CSA exhibits significant improvements in solution quality, convergence speed, and robustness. These results verify the effectiveness and advancement of the proposed model and algorithm in solving complex engineering scheduling problems.
