| Abstract: | The cleaner production assessment of coking project was conducted according to Cleaner Production Standards-Coking Industry(HJ/T126-2003),in which there were 87 assessment indexes,this resulted in the difficulties of data collection,moreover standard comparison method was adopted to get only the cleaner production level of every assessment index,was unable to determine the cleaner production level of some project in coking industry.In order to clear the relationship between the cleaner production levels of ... |
| Keywords: | principal component analysis(PCA) standard comparison method cleaner production assessment assessment indicator coking industry |
