Analysis of cost and energy consumption for venous trasportation

今年，货车的油耗主要调查在运输过程中。通过对船公司的调查，很难单独获得往返的燃油消耗数据。使用勉强获得的16辆卡车的数据，我们得到了如下的能耗作为车货总重的函数公式：y = 36.2 x^<0.419>, R^2=0.80然后，根据油耗标准，得到如下公式：手动挡柴油车：y= 51.2x^<0.354>, R^2=0.99；自动挡柴油车：y=49.0x^<0.383>, R^2=0.94；手动挡汽油车：y=4.8x^<0.697>, R^2=0.96；并以包括厢式车在内的6辆轿车为研究对象，通过改变载客量进行了油耗实验。得到如下公式：。对于节能型轿车，y=113x^<0.197>, R^2=0.96，或y=100x^<0.214>, R2=0.95，对于厢式轿车，y=158x^<0.234>, R^2=0.79。无论如何，认为能源消耗与汽车总重量成正比是不现实的。因此，在分析山口县所有生物质废弃物运输到宇部市所需成本和能耗的案例研究中，利用以上16辆卡车的数据，采用公式y=16.2x^<0.5>, R^2=0.74。比较了按订单将芯片厂数量分别减少到19、13、6家的效率。从成本和能源消耗的角度来看，减少数量是不利的。输送所需能量在0.51% ~ 0.67%之间。

This year, the fuel consumption of cargo truck was mainly investigated on transporting process. Hearing surveys to shipping companies could hardly get available data of the fuel consumption separately for back and forth. Using the data barely obtained for 16 trucks, we got the following formula of energy consumption as the function of overall weight of car and cargo. y = 36.2 x^<0.419>, R^2=0.80. Then, according to fuel consumption standards the formulae were obtained as shown below.For diesel truck with manual gear: y= 51.2x^<0.354>, R^2=0.99, with auto-gear: y=49.0x^<0.383>, R^2=0.94 For gasoline truck with manual gear: y=4.8x^<0.697>, R^2=0.96 and for gasoline own car: y=1.44x^<0.856>, R^2=0.97. Moreover, using 6 cars including van-type, the experiment of fuel consumption was carried out by changing the number of passengers. The following formulae were obtained,. For fuel-saving car: y=113x^<0.197>, R^2=0.96, or y=100x^<0.214>, R2=0.95, and for van-type car y=158x^<0.234>, R^2=0.79. Anyhow, it is not practical to consider that energy consumption is proportional to the overall weight of car. Therefore, in a case study to analyze the cost and energy consumption necessary for the transportation of all biomass waste in Yamaguchi prefecture to Ube city, the formula y=16.2x^<0.5>, R^2=0.74 using the data of above 16 trucks was used. Comparing the efficiency in cases that the number of chipping plants is decreased to 19, 13, 6 by order. By decreasing the number it becomes disadvantageous from the point of cost and energy consumption. The necessary energy to the transportation is in the range from 0.51% to 0.67%.
