摘　　要：港口“多品种,小批量”的原料取配送服务助力钢厂实现JIT生产,但取料机故障等作业突发事件也成为制约“港-钢”连续作业与生产的重要因素。因此,本文基于柔性生产机制提出精细化取料工艺,并以作业完成时间最小化为目标建立取料机应急调度模型,设计IBFA算法进行求解。最后,结合故障事件进行仿真实验,得出并分析了取料机应急调度方案。结果表明,应急调度可有效降低突发事件带来的影响,提高港口作业的柔性和效率,为实现港口物流链与钢厂生产链的无缝衔接提供科学的理论与方法。With the development of the port industry and the continuous ssprogress of the transformation of traditional industries,the“Port before Factory”was successfully born.The meaning of“Port before Factory”is“the port in front and the steel enterprise in the rear”,which is an innovative form of enhancing the cooperation between the port and the iron and steel enterprise.After the raw materials needed by steel enterprises arrive at the port,its are temporarily stored in the port yard.Then,according to the production needs of steel enterprises,after the reclaiming operation of the reclaimer,the raw materials are delivered to the production line of steel enterprises by the port in a fixed,fixed and quantitative manner.Under this mode,the port reclaiming operation is more frequently driven by the“multi-variety,small-batch”raw material distribution orders of steel enterprises,which puts forward higher requirements for its operation quality and distribution time.And there is uncertainty in the operation of the reclaimer.Therefore,how to deal with the failure of the reclaimer has become the key to affecting the cooperative production of ports and steel enterprises.In order to improve the agil⁃ity of the reclaiming operation in the yard,the flexible production theory of the manufacturing industry has been introduced into the management of the reclaiming operation in the port,and the refined reclaiming process has been proposed,which includes three aspects:the layout of the yard,the process of the reclaiming operation,and the emergency scheduling scheme of the reclaimer.Among them,in the emergency scheduling scheme,through multiple scheduling,the delayed tasks caused by the failure of the reclaimer are evenly distributed to other equipment,which reduces the impact of emergencies on the overall operation progress.On the basis of the refined reclaiming process,with the goal of minimizing the job completion time of the reclaimer,an emergency scheduling model of the reclaimer is constructed.In addition,since the
