摘　　要：针对我国未来“八纵八横”高速铁路网络背景下的时速250 km以上货运动车组货运产品设计问题,首先采用不等权组合预测模型预测全国货运量及发展趋势;其次构建各货运方式货运量-平均运距、分担率-平均运距的拟合曲线及表达式,确认铁路货运优势平均运距及区间最高分担率;再次,定位货运动车组货运产品为铁路高端货运市场;在此基础上结合其特点对其货物品类,明确分担率及未来需求;最后从产品属性定位出发,建立效益最优化与综合评价模型,结合铁路货运产品谱系,设计出以当日达、次晨达、次日达为主的货运动车组货运产品谱系.Aiming at the design of freight products for freight multiple units with speeds over 250 km per hour under the background of"eight vertical and eight horizontal"high-speed railway network in China in the future,the unequal weight combination forecasting model is used to forecast the freight volume and development trend of the whole country,and the fitting curves and expressions of freight volume-average distance,share rate-average distance of each freight mode are constructed to confirms the superior average distance of railway freight transportation.The freight products of EMU are located as the high-end freight market of railways,and the share rate and future demand for its freight categories are clarified on the basis of the characteristics of EMU.From the product attribute positioning,the benefit optimization and comprehensive evaluation model is established,and the pedigree of freight products of EMU is designed for the main products to reach the same day,the next morning and the next day.

关 键 词：货运动车组货运 货运量 平均运距 分担率 货运产品 综合评价模型
