灰色关联度分析法是对多因素之间发展趋势的相似或相异程度的描述,是灰色理论的一项重要组成部分。首先将各烧结指标赋予权重值,将其划分为3个等级,然后基于灰色关联度法计算出6组试验方案的烧结指标与理想指标之间的关联度,根据关联度排序进而确定出各方案的优劣情况。最终得出印尼海砂最佳配比为7%,最高配比应不大于12%,实际生产表明该方法可行有效。
Gray relational analysis is a description of the similarity or dissimilarity of the development trend among multiple factors and is an important part of gray theory. First of all, each of the sintering index is assigned to the weight value, which is divided into three levels. Based on the gray relational degree method, the correlation between the sintering index and the ideal index of the six experimental schemes is calculated, and then the schemes are determined according to the degree of relevance The pros and cons of the situation. The result shows that the best ratio of Indonesian sea sand is 7% and the highest proportion should not be more than 12%. The actual production shows that the method is feasible and effective.
