Along with the expands of guest roll conveyance and the fury in the market competition more and more , its hardware environment ( i . e . , the berth and the ship ' s amount ) is shortage ; its software environment , such as the management , operate etc . , also cannot keep up with the situation more and more 在港口滚装业不断膨胀、市场竞争越来越激烈的同时，其硬件环境，如泊位、船舶数量等越发显得不足；其软件环境，如管理、经营等也越发显得跟不上形势。
The conditions of the lashing system on board chinese ro - ro ships are investigated and the western research results of the same problem are introduced and compared . in chapter 3 , mechanical and mathematical models for the estimation of the loads in the lashing systems of road vehicles on board ro - ro ships are developed . the result is calculated and simulated by the computer program which was provided by professor s . turnbull from oxford university , britain 通过比较国外同类问题的研究方法，针对我国现有滚装航线上实际运输生产中的车辆绑扎系固的状况，作者采用了建立滚装船上车辆绑扎系固力学和数学模型，并结合专门的计算机计算程序计算和模拟结果的方法，对滚装船上车辆绑扎系固的绑索的受力情况进行了全面的定量分析和计算。
Surveying & comparing on basic conditions of large port area and related port areas , the author forecasted scale of transport volumn & trend of development ( transport volumn of domestic container , bulk cargo - , roll vessel , passenger transport of high speed & routine liner , type of ship ' s development ) by mathematic method . operating distribution , adjusting programming , regulation of programming area and reconstructing time & function were put forward , steps and ways of exploitation were established 并对大港区及相关港区基本条件进行了系统的调查比较，运用数学方法对大港区运量规模与发展趋势(内贸集装箱运量、大宗散货运量、滚装运量规模及发展预测、滚装、高速、常规班轮客运量、船型发展预测)进行预测分析，提出了未来生产布局调整规划与规划区域的界定，及改造时机与功能规划，制定了开发步骤与开发方式。
Highway : it is an intersetion of weiwu expressway ( nationhighway ) , pengshui highway , muhuang highway ( bothprovincialhighways ) and pengfeng highway ( town - levelhighway ) . itisalso connected with jiqing , tongsan expressways as wellas the expressway network in three provinces in northeast china through penglai ? dalian ro - ro navigation line . the transportation is quite convenient 公路? ?国道威乌高速、省道蓬水路牟黄路、县道蓬丰路在此交汇，连接济青高速、同三高速，通过蓬（莱）大（连）滚装航线与东北三省高速公路相接，形成四通八达的公路交通网。
2 ) the small - sized shipping companies should take the vivid strategy , develop the source market positively , chahge the sea - going ship and combinate the cargo source condition . thus , it takes the direction to container , roll - roll and liquid ships and develop railway and river combinated , main and auxiary road combinated , river and sea combinated , main and auxiary road directly reached , river and sea directly reached , various ways close combinated . 3 ) we reduce the passenger transportation of the changjiang river , on the other side , we should develop the passenger travel market 2 、中小型航运企业要制定灵活的发展战略，积极开辟货源市场，结合货源情况，对适航船舶进行改造，使长江运力朝集装化、滚装化、液装化等特种运输方向发展，走联合发展的路子，开展铁江联运、干支联运、江海联运、干支直达、江海直达多种方式紧密结合。
