摘要
格序决策方法在对区间数进行优劣排序方面尚有改进完善的余地,通过研究发现,改进后的格序决策方法在不可比较区间数的优劣排序上不必求出拟上、下确界,也没必要绘制偏好结构图和海赛图来进行整个过程的优劣程度排序.通过算例比较验证了改进后的方法更加简洁有效,更加有利于提高决策的效率.
The lattice order decision-making method still has leeway to be improved and perfected , by studying shows lattice order decision-making method to be improved need nether calculate the ordering superior or inferior being in progress to lattice order and nor draw preference structural drawing and Hassel picture to carry out entire process in interval numbers. Having been testified the method to be improved comparatively concisely and effectively by calculating an example, it is especially beneficial to improve decision-making efficiency.
