修造梯田需要大量调运土方。土方调运得是否合理,直接影响梯田的修造进度和劳力的安排。一九七五年,我们将科学出版社出版的《运筹学》第二章关于解决物资调运问题的图上作业法原理,移用于人工修梯田中解决土方调运问题,很有效果。简介如下。梯田施工中土方运输量是以调运土方数(立方米)×运距(米)来表示的。因此修造梯田时应找出土方总运输量最少的方案。用图上作业法寻找土方调运最少的方案,有如下几个
To build terraces need a lot of transport earthwork. Whether the transfer of earthwork is reasonable or not will directly affect the progress of the construction of terraced fields and the arrangement of labor. In 1975, we transferred the principle of the working method on the map of operations operations, Chapter 2 of Operational Research, which is published by Science Press, to the problem of earthwork transportation in man-made terraces. It is very effective. Brief introduction is as follows. The amount of earthwork in the terraced construction is expressed as the number of earthwork transported (cubic meters) × distance (meters). Therefore, the construction of terraces should find the least amount of earthwork transport programs. Use the map method to find the least earthwork transfer program, the following
