产销区划分析公式

(1)两个方向的运输成本近似比例:

式中,tt分别代表重车和空车方向的运输成本;RR分别代表重车和空车的平均总重量; KS代表空车列车运行每总重吨公里的费用与重车列车运行同样费用的比例。
(2)
相邻两生产基地产销分界点分析公式:

式中,C1C2别代表两生产基地的生产成本(元・t-1);t1t2分别代表由两生产基地至分界点的运费率(元・t-1km-1); l1l2分别代表由两生产基地至分界点的距离(km)
(3)
考虑产品效益时的相邻两生产基地产销分界点分析公式:

式中,U1U2分别代表两生产基地的单位产品的效益量。

(4)产销区划中的基本建设投资分析公式:

式中,Cn1Cn2分别代表计算期中两生产基地不包括固定资产折旧的生产成本(元・t-1); tn1tn2分别代表计算期中两生产基地产品运输不包括交通线固定资产折旧的运费率(元・t-1km-1); l1l2分别代表由两生产基地至分界点的距离(km)
