【摘要】 为研究铁路与公路运输在现代物流中的协调性,运用数据包络分析方法,以1990—2004年间中国公路、铁路运输的相关数据作为输入和输出指标,并将数据进行标准化和综合化处理,利用DEA模型,用LINGGO编制线性规划求解程序,计算协调发展程度。计算结果表明,公路运输与铁路运输之间协调性随着年份的推移有良好的发展趋势,但在此期间内也有少量波动,反映出国家公路与铁路运输的发展程度及趋势。更多还原

【Abstract】 In order to research coordination between railway and highway transportation in modern logistics,the paper uses DEA(Data Envelopment Analysis),takes relevant data of China railway and highway transportation from 1990 to 2004 as input and output indices,makes standardized and integrated treatment to the data,applies DEA model and LINGGO to establish solver of linear planning and calculate degree of coordinated development.Calculation results show that coordination between railway and highway transportation becomes better in past years,despite some fluctuation.更多还原
