Called the trainman , as , after a few minutes of darkness and smoke , daylight reappeared 在黑暗和烟尘中过了几分钟后,又重见了天日。
With the improvement of train speed and the quantity of passenger increasing , how to inform traffic departments parameters about train in good time and report vehicle - dispatching information to trainman so as to guarantee security of train ' s run and management of traffic department is still one of questions which are in dire need of solution 随着我国列车运行速度的提高以及客流量的大幅度增加,如何保证将机车车辆的运行状态等技术参数实时传输给运输指挥和管理部门,以及如何及时、可靠、安全地将地面调度信息告知机车乘务员,实现运输安全的有序可控、确保行车安全是急需解决的技术问题之一。
Vsp is both a pivotal tache in logistic distribution optimization and indispensable in electronic commerce . it can increase logistic economic benefit and realize logistic rationalization . the systemic study on the theory and method of vsp is the base on the growth of logistic intensivism , the establishment of modem chain of command , the development of its and ec . now , the problem is not only applied to the field of auto transportation , but also to ship avigation communication electricity industry management computer application etc . the algorithm has been applied into many combinatorial optimization problems such as the trainman ' s shift arrangement in avigation the optimization design of cargo arrangement in ship company 对货运车辆进行调度优化,可以提高物流经济效益、实现物流科学化。对货运车辆调度优化理论与方法进行系统研究是物流集约化发展、建立现代调度指挥系统、发展智能交通运输系统和开展电子商务的基础。目前,问题的形式已有很大发展,该问题以不仅仅局限于汽车运输领域,在水运、航空、通讯、电力、工业管理、计算机应用等领域也有一定的应用,其算法已用于航空乘务员轮班安排、轮船公司运送货物经过港口与货物安排的优化设计、交通车线路安排、生产系统中的计划与控制等多种组合优化问题。
