基于变权物元可拓模型的烧结矿质量评价

Quality Based on Matter-element Extension Model with Variable Weight

烧结矿的质量评价是一个涉及多指标的复杂过程,而烧结矿的质量对钢铁生产具有重大的影响,准确地评价烧结矿质量有利于优化烧结矿的生产工序。提出了基于变权物元可拓模型的烧结矿质量评价方法,运用变权理论来确定不同评价指标的权重,减少了在烧结矿质量综合评价时的主观因素并体现了各评价对象在质量评价中的主动性。以某钢铁企业烧结生产的实际数据为例,综合5个不同的烧结矿质量指标,对烧结矿质量进行综合评价,验证了模型的有效性。

The evaluation of sinter quality is complex since it concerns different indexes, while the quality of sinter has great influence on steel product, evaluating the sinter quality accurately works for the optimization of the sinter production process. In order to evaluate the quality of sinter, an evaluation model based on variable weight matter-element extension is built. We utilize the variable weight theory to solve the weight of different indexes, which reduces the subjective factors and reflects the initiative of each object when evaluating the sinter quality. Taking measured data from an iron and steel enterprise for example, 5 different indexes of sinter quality are combined to evaluate the quality, the result shows that the model is effective for comprehensive evaluation of sinter quality.
