摘　　要：通过对航道维护船艇现行备件物料供应保障体系进行调研分析,发现多数供应保障优化研究成果局限于成本费用最佳而忽视备件物料需求时效性的问题,提出将航道维护疏浚任务等级进行划分,建立时间竞争成本模型,引入排队论中强占优先权法对不同任务等级供应保障时间成本进行优化,通过算例找出各环节服务机构的最佳配置。The spare parts and materials supply guarantee system is investigated for the waterway maintenance ships in Yangtze river. It is shown that the current researches of supply guarantee usually concentrates on cost optimization rather than the timeliness of waterway maintenance task. In order to solve this problem, a method is set forth to classify task levels of waterway maintenance dredger and establish a time competitive cost model. The preemptive priority method of queuing theory is introduced to optimize supply guarantee time cost model for different levels of task. A numerical example is given to obtain the best configuration in different supply guarantee service stages.
