基于AHP和PCA的企业能耗水平评价

为了对企业能源消耗水平进行评价,构建了能耗水平评价模型,并对各项能耗水平指标的内涵作了解释;利用主成分分析法(PCA)对底层指标做了综合,作为相应准则层的指数;利用层次分析法(AHP)确定了各个层次能耗水平指标的权重,最后用一个实例来说明该能耗评价模型是可行的。

To Evaluate on the Level of Enterprise Energy Consumption Based on AHP and PCA

In order to evaluate the level of enterprise energy consumption,a energy consumption model on enterprise was established.Each of energy consumption indices was explained.The result obtained from the bottom indices by using the principal component analysis(PCA)was used as the index of the relevant criteria.The energy index weight on every level was determined by using the analytic hierarchy process(AHP).Results show that the evaluation of enterprise’s energy consumption level based on AHP and PCA is feasible.
