The study of assessment index system and method on coal enterprises circular economy
Based on Circular Economy and the evaluation index system of general principles, combined with the characteristics of China's coal companies, Coal enterprises built this first evaluation index system of circular economy. The index system consists of resource outputs, resource consumption, comprehensive utilization of resources, waste disposal four-level indicators, each level indicators and include the corresponding secondary indicators; and then determine the AHP based on entropy and the circular economy of coal enterprises evaluation method, the use of AHP are subjective evaluation of the object weight and calculate the entropy information inherent in the combination of the right to obtain comprehensive weight; Finally, the calculated level of economic development in the coal enterprises circular index. The evaluation method of coal enterprises in Henan province has been the specific application, the effect is better.
1 Summary For Case Western Reserve University’s debut participation in TREC, we chose to participate in the Enterprise Track expert search task. Our motivation for participation stems from our work developing expert search capability for our prototype vertical digital library, MEMS World Online 1 . Our work incorporates two unique aspects. First, our relevance ranking mechanism relies on term position within each document rather than the number of term occurrences. This mechanism takes into account both term document rank and term co-occurrence proximity. Second, the expert score of closely related colleagues has a small eect on the score of each related expert. This follows the intuition that experts on a particular topic within a single organization tend to closely collaborate with one another. We also make some use of WordNet synonyms. We submitted a total of three runs to this years expert search task.
