| 摘 要： | TOPSIS（technique for order preference by similarity to ideal solution）法是一种多目标决策方法，其思想在河流污染检测中可用于解决多目标系统的优化布点问题。本文详细介绍了TOPSIS法的原理、度量距离以及TOPSIS方法的详细计算步骤，并在求一般目标与理想目标的距离时尝试对其进行改进。实例表明：改进后的方法充分运用了优化矩阵的信息，优选结果符合客观实际情况。在开封市境内的各个河流共计13个断面采样点中，经过改进后的TOPSIS方法优选后只需检测第1，4，6，8，9和11号断面即可，这样利用尽可能少的检测断面获取了最有空间代表性的环境信息，由此可见这种方法在河流污染检测中有较高的合理性和实用性。 |

| Abstract： | TOPSIS (technique for order preference by similarity to ideal solution) algorithm is a multi objective decision method, which can be used for distributed points of optimization problem of the multi objective systems in the testing of pollution in the river. This paper has introduced the TOPSIS method’s principle, metric space and its detailed calculating steps. It has tried to improve this method when the distance between general object and ideal goal was being solved. The example shows that the improved TOPSIS method makes the best use of optimal matrix information, and the optimizing result is in accordance with the actual situation. Through this method only the 1, 4, 6, 8, 9 and 11 ones of the 13 section sample points of the rivers in Kaifeng city need to be tested. And the maximum spatial representative environment information can be got with the minimum testing section. It shows that this method is effective and applicatory. |
