受限水域积压船舶应急疏导组织优化决策模型
|
摘要
为平衡受限水域船舶长期积压可能带来的损失及应急疏导组织所需的人力、资源等成本投入,从积压船舶应急疏导组织实际需求出发,以保障通航安全性为约束条件,构建应急疏导组织投入与积压损失最小的多目标优化(MOP)模型;针对三峡坝前积压船舶开展模型实证研究,提出符合船舶积压现状的疏导途径,并运用遗传算法(GA)求得其应急疏导组织策略。研究结果表明:所构建的多目标优化模型能为决策者提供不同偏好下的受限水域积压船舶应急疏导组织优化决策方案集。
The paper was aimed at facilitating the balance between the loss of long-term shipping backlog in restricted waters and the cost needed for emergency evacuation organization. A multi objective optimization model with minimum cost and backlog losses was built after considering the actual demands of the shipping backlog emergency evacuation organization,and the constraints of water safety objective. The model was verified by the example of the emergency evacuation organization of the ship backlog in the Three Gorges Dam. The GA was applied to get the emergency evacuation organization strategies in this restricted water. Results of this study demonstrate that the multi-objective optimization model can provide different emergency evacuation organization optimization schemes for decision-makers different in risk preference.
