耙吸式挖泥船疏浚施工组织仿真优化*

合理制定最佳疏浚施工组织计划，需要考虑众多影响因素及其不确定性且各因素之间相互影响。通过航道疏浚工程施工作业仿真模型，描述运营船舶进出港和挖泥船疏浚施工过程中存在的不确定性，以最小化船舶船班费用和碳排放成本之和为目标，重点分析疏浚段长度和挖泥船船队配置对疏浚工程船舶船班费用、碳排放成本以及综合成本的影响。结果表明，提出的基于仿真和优化的方法可合理制定疏浚工程施工组织计划。

Simulation and optimization for dredging construction organization of trailing suction hopper dredger

To develop an optimal dredging construction organization plan,it is essential to consider various influencing factors along with their uncertainties,all of which interact with one another.We develop a simulation model for dredging operations in waterway dredging projects to describe uncertainties involved in vessel arrivals and departures,as well as in the dredging process of trailing suction hopper dredgers.Based on the objective of minimizing the total cost,we analyze the impact of dredging section length and the dredger fleet on dredger operation expenses,carbon emission cost and comprehensive cost.The results indicate that the proposed method based on simulation and optimization can develop a rational construction organization plan for dredging project.
