摘要
根据我国磷矿、磷肥运输网络的现状及特点,运用系统工程原理,采用图论方法和数据库技术,建立了全国磷矿、磷肥运输网络计算机系统。该系统可生成铁路运输、水路运输、铁水联运等多种运输方式下的费用最少路径及其他任意路径或两者的混合路径,并计算出相应运距、运价等数据。该研究在"七五"国家重点科技攻关项目"全国磷资源开发系统研究"中已获满意的应用。
On the basis of the present conditions and characteristics of national-wide transport network of phosphate ore and phosphate fertilizer, the systems engineering , graph theory and database technique have been applied to create a national-wide computer transport network system of phosphate ore and phosphate fertilizer. The system can develop a most economical route or arbitrary route or the above combined route by selection from various transport ways such as rail,water and their combination,and can calculate the relative transport mileage freight, etc. The system has been successfully used in the national phosphate resources development
system study--a national science and technology key
project in the seventh Five-Year Plan.
