摘要
对各产销量和单位运价既定的运输问题,可用表上作业法等求出相应的最优解。但当前的产销系统中是否存在不合理的产量布局、如何制定合理的产量布局以及当某地产(销)量发生变化时,应首先相应地调整何处的销(产)量,才是经济上最合理的,目前尚缺乏定量分析方法。本文通过对运输问题的分析,提出运输问题边际值的概念,并阐述如何应用边际值来解决上述问题。
For the transportation problem to which the different amount of supply,demand
and shipping cost per unit is known;the relevant optimal solution could be found
by transportation statistical tables or other simplex mcthods.However,there are not
any quantitative methods of analysis yet on such problems like whether the distri-
bution of supply in the current systems is rational or not,how a rational distribution
of supply sould be worked out,and which demand(supply)should be adjusted with
economic rationality as a certain supply(demand)alters somewhere.In this paper,
the solution of these problems is discussed and acquired by use of the concept of the
marginal value of the transportation problem derived from the analysis on the trans-
portation problem.
