【摘要】 本文以煤炭港口路径选择提供理论依据和提高港口周转率为目的,通过实地调研和阅读国内外文献,建立煤炭港口的GPRs网络;通过借助GPRs网络的双箭线表示法,将工序间的时间约束关系清晰的表示出;通过借助GPRs网络的单线表示法,方便的找出中性关键工序等奇异关键工序,这不但为煤炭港口路径选择问题提供理论依据,还为提高煤炭港口设备利用率和煤炭在港周转率的研究开拓了一条新途径。更多还原

【Abstract】 The process route of coal port is introduced in this paper.It can be found that there is an abnormal phenomenon;under certain conditions,reduce coal port material taking machine work sets,port turnover unchanged.It against the traditional concept that when to reduce the material taking machine work sets,the port turnover will be reduced.The abnormal phenomenon can improve the coal port equipment utilization and the port turnover.Firstly,the characteristics of the process flow in coal port is analyzed.Then,a coal port GPRs network is established.Lastly,it can be found that there is an abnormal phenomenon in coal port working process.更多还原
