法在优选电厂配煤比中的应用

介绍了逼近理想解排序法—TOPSIS算法,同时利用熵值法确定指标的权重,并详细描述了该方法在优选配煤方案中的应用。以电厂混煤燃烧问题为例,在挥发分、着火温度、发热量和成本4种指标下,对4种配煤方案进行了优化选择。该方法能有效结合定性与定量分析,充分综合各指标评价信息,为混煤方案优选提供一种较为有效的方法和途径。 The method of TOPSIS is introduced.The application of TOPSIS method in seeking the optimum mixture ratio of blended coal is described in much detail by confirming the weight of index with entropy.For example,the combustion issue of blended coal in power plant is used and,the optimum mixture ratio is selected under the condition that four aims and four kinds of blended coals.The method can combine qualitative analysis with quantitative analysis effectively,integrate evaluating information of each index adequately,which provides a good way for the optimization of blended coals
