This essay stems from the problem with which tianjin port is confronted , contributes to the research method and theory on how to allocate equipment in order to optimize the efficiency of the loading and unloading assembly line . up to now , there is no a ripe method on that above . so , this paper applies optimum method and economics theory , attempts to set up a series of analyzing methods and optimum models to improve the efficiency of dock loading and unloading , and reduce the operating costs , and increases more profits 本论文从天津港生产中的现实问题出发，结合发达国家港口设备管理的经验与中国港口的实际，通过对港口装卸作业系统地分析，逐步缩小系统的研究范围，确定提高某一码头作业线的机械装卸效率为研究目的，建立一个作业线合理选择工艺流程和配机的数学模型，并提出相应的解法。
Over the years , obsorbing the advanced technology , the association has developed the straight line drawing machines , wet drawing machines , upside down style wire drawing machines , spool take - up , pay - off unit , wheel heat treating winder , heat treatment take - up , pay - off unit , strander machines , pre - treatment line machines 多年来，吸收先进的专业技术，已研制开发了具有国内领先水平的直进式拉丝机，水箱拉丝机，倒立式拉丝机，收放线机组，工字轮热处理收线机，热处理收放线机组，预处理作业线，管式股绳机和成绳机。
As a key part of the port crane , slew bearing ' s fault has a negative impact on the efficiency of the whole product line , as well as great direct and indirect loss . because of its compact structure , direct observation and frequent disassembly are not available for monitoring and routine management 大型回转轴承装置是港口起重设备的关键部件，一旦发生故障，会影响整个作业线生产，带来巨大的直接和间接损失，而其大型、封闭的结构又决定了不能依靠直接观察和频繁拆卸来对其进行故障监测，这就给大型回转轴承装置的日常管理带来了困难。
The company as an export - orientated enterprise is engaged in manufacturing matching decorative items of cars and has formed several production lines and powerful r & d team to meet the needs of customers . with the principle of adhering to responsibleness , sincerity and reliability and the aim of developing further and better , the company has gained large praises and popularity from customers at home and abroad 本公司以专业生产激汽车配套装饰品为主的外向型企业，目前已形成多条作业线和技术研发力量，保障用户的需求，爱信本着务实，诚信的原则，追求更高，更远，更实，更精的目标，已赢得国内，国际上众多客户的赞誉与信赖。
In the paper , the methods how to manage the raw material fields is devoted . accord to the wuhan iron and steel ( group ) co . industrial port " s level , with operation research , physical distribution , computer technology how to deal with transport , loading or unloading stockpiling advance an idea . in the paper , the raw material fields " physical distribution system is departed to three part : optimum burden , the best line , loading and unloading advance , step by range and step by level , its can be implement so as to improve the product ' s competition ability 本课题的研究内容主要是原料场混匀配料及作业线系统优化，它包括配料计划的选择及作业线选择、料场的货位及贮量的合理配置等几项的综合优化，是一个比较大的物流系统的规划。主要以武钢工业港原料场为例证展开研究的。配料计划的优化是以可以降低成本并保证成份控制为目标进行线性规划的。
The dsh mech . recently copes with the production and installation of the equipments ( and related coating lines ) for the internal or external pipeline anticorrosion coating , all of which comply satisfactorily with relevant national or international standards and guidelines for steel pipe anticorrosion technology 近年来我公司一直从事管道内外涂层防腐设备的制造与安装,并生产制造与之配套的各类防腐作业线；作业线成果能够完全按照国内和国际上通用的管道防腐技术标准进行钢管内(外)涂层涂敷。
