摘　　要：船闸施工量庞大、涉及资源多、各工序交错复杂,仅凭人脑经验很难站在全局的角度制定科学、精确的施工计划。在多资源约束下,对船闸施工网络计划仿真建模和资源均衡优化方法进行研究。在分析典型船闸施工流程设计和施工空间划分的基础上,建立典型船闸工程施工网络计划仿真模型和多资源约束下船闸施工网络计划“工期固定-资源均衡优化”的数学模型,设计相应的遗传算法,并通过实际工程进行验证。结果表明,此模型和算法可行、有效,解决了多资源限制下的船闸施工网络计划资源均衡优化问题,为船闸施工进度、资源以及成本管理提供科学有力的依据。The ship lock construction has huge workload,which involves many resources and interlaced and complex various processes.Therefore,it is difficult to make scientific and accurate construction plans from the overall point of view only on the basis of human brain experience.We study the simulation model and resource balanced optimization method of ship lock construction network plan under the constraints of limited total multi-resources,establish the simulation model of construction network planning for typical ship lock project and the“fixed construction period-optimization”mathematical model of lock construction network planning under multiple resource constraints based on the analysis of process designing and space division of typical ship lock construction,design the corresponding genetic algorithm to solve it,and verify by engineering application.The results show the model and algorithm are feasible and effective.It solves the resource balanced optimization proplem of ship lock construction network plan under the constraint of limited total multi-resource,which can provide the scientific and powerful basis for lock construction schedule,resources and cost management.
